Easy to do in old BMWs since the iDrive screed is embedded in the dash and my smart phone fits snugly in this slot .

Where the in built navigation comes handy for me is on two lane highways and twisty curvy roads. I turn on the nav screen and it gives me a good idea of how the road curves up ahead. Not saying that I trust it completely to plan overtaking maneuvers etc... But it's nice to know if there is a sharp curve ahead. Also if I am out of home town it does throw up some good info like road names, fuel stations, eateries etc... around the area that you are driving through.
Hi. the absence of traffic info is definitely a negative as far as the F25 Nav system is concerned. Where the NAV does score is accuracy, it locates the car with far more accuracy in an urban canyon versus either my iPhone or nexus (probably due to the external antenna) The HUD integration is another plus, And it also works very nicely with the DTE indicator in the instrument cluster.

Will try to get an update can see accurate and useful it is. if CarPlay worked on this, I wouldn't even make the effort.

Update : Drivetrain error – Faulty EGR valve.

The infamous 'drive train' error popped up in my car about a month ago during Diwali time while I was driving to the airport to drop off some relatives.

Power corrupts! My BMW X3 xDrive30d M Sport. EDIT: 3.5 years & 50,000 km update!-img_20191026_153631.jpg

The car went into some kind of safe mode on the fly, as I could feel the reduced performance. The engine wasn't revving beyond 2k RPM or so and the car felt real sluggish. I have read many instances online about BMWs where such errors are one off cases and the error just goes away after doing a full ignition off and restart routine. I was afraid that the car might not fire up at all if I turned the ignition off, so I found a deep enough slot at the departure drop off and turned the ignition off and started the engine again. The engine did fire up but so did the error, which came on within a few seconds of startup.

Luckily Navnit Motors service centre is just a stone’s throw away from the airport and I decided to drive straight to the service centre and report the problem. But as luck would have it we got caught in a major traffic jam caused by a prominent political leader's return and his supporters celebrations which blocked the airport road for nearly 2 hrs. Every inch of space was taken up on the road and there was total frenzy and break down of all order. Cars were just inching up at a rate of 1 metre per five minutes!! If it's the transmission we are looking at here, this was not what the doctor ordered, surely. A complete breakdown here would have been catastrophic. I kept the engine running and moved to N at all times whenever we were stationary. I had some guests waiting at home and Dad, who was with me at the time, was in no mood to go to Navnit and waste further time. Since the car was running, we decided to drive on towards home . We somehow made it back home (we were stuck on the road for nearly 2.50 hrs in the jam) and parked the car at it's usual parking place.

The next morning I wanted to check on the car and fired her up. Same error within a few seconds flashed on the screen. But this time it was accompanied by a check engine light on the cluster. I am pretty sure it wasn't there the previous day. I moved the car forward a few meters and then it happened. The car started shaking and the engine sputtered a few times and just died bang in the middle of our driveway. I tried to fire up again after a couple of hours just to see if I could move it to the side. Same result. I got out and could smell something burning. Popped open the hood. No smell, no smoke. Bent down and felt the smell coming from underneath the car. I made no further attempts to start the car.

If this had happened to us the previous day in the traffic jam , I can't imagine what our plight would have been! The next couple of days the car stood in the middle of the drive way as it was the festive weekend. I did reach out to BMW roadside assistance and they were ready to send me a tow truck to tow the car to the nearest service centre albeit on a chargeable basis since my car is not covered under RSA. Since Navnit was closed anyway I decided to contact them directly once they resumed duties.

Observations
  • The car was shifting gears fine all this while. I did not feel any jerk etc.. from the engine or gearbox.
  • Since about a month or so, the car was just shuderring a little during start up and shut down. It was barely noticeable actually. But when we shut the car off at the airport the shake during shut down was definitely more violent and noticeable.
  • Engine oil level was at full level. Temp gauge was showing normal reading.
  • The engine was sounding kind of funny in that safe mode.

I suspected a faulty fuel pump. As per the internet this is a common problem with BMWs. Drivetrain errors can mean anything from the transmission to the turbo to the injectors or any failed sensors. This was the first time such an error had popped up in the car and I was quite disturbed by this occurrence. Although I had warranty, I was scared of the scenario where the service centre is unable to diagnose the issue properly and I end up facing recurring issues and multiple visits etc.. It has happened with many German car owners and well documented on our forum.

Another possibility was adulterated diesel. But I had driven all the way to Belgaum and back just 15 days back and the car was absolutely fine. I had last tanked up in Belgaum (60 litres of diesel) and driven all the way to BLR. The car was running on the same fuel even now. So I didn't think it could be adulterated diesel.

Thinking about the places I've taken my car, I can't imagine what I would have done if this had happened during those drives, esp with family. Just last year I drove to godforsaken places like Honnemaradu with family. My running is 90% highway. So the car dying like this in my own parking place was a miracle in itself.

I contacted the dealership thereafter and they sent their mobile assistance team over. At first the technician suspected bad fuel. But when I said I am running the same fuel for the past 600 odd kms, he said it could be due to low fuel in the tank. (The reserve fuel icon had just lit up and range remaining was about 80 kms). He said sometimes when the fuel level goes down, air or vapour gets trapped and the pump may not be able to build pressure. He gave me a jerrycan and asked me to bring 5 Lts of diesel so that we could top up and see if that helped. He wanted to bleed the fuel lines once.

He had his diagnostic tools with him, so I wanted him to run the diagnostic scan first so that we could see what the error code is. So we plugged in the laptop and the error code was : 255C00 - EGR Valve position control. Valve open too wide.

We topped up diesel and tried starting. Engine started, but within a few seconds the engine died in a similar fashion. The diagnostics guided him to open a plastic trim and move a spring-loaded attachment manually. He did that and also lubricated it with a spray and then poured some synthetic engine oil over it. We started the car and the car fired up normally. No drivetrain error, no CEL. He then ran some EGR diagnostic program cycles which lasted about two minutes each time and the engine would rev up and the black circular flap like thing would turn left, turn right, turn left, turn right. Quite a flimsy looking thing it is with a thin rod connected to it which would open the actual valve deep inside I suppose.

After doing this, the engine idled normally and there was no error code in the car. But I could see in his laptop when he ran the scan once again, the same error code showed up and with the word "existent" next to it.

We did a small test drive and the car drove normally. He suggested I take the car to the service centre and get it checked thoroughly once. I was apprehensive to drive the car, but the technician said there was very little chance of it stalling again. The service centre is about 15 kms away on Airport road. I suggested he follow me till the service centre just in case the car broke down in the middle of the road. He assured me the car won’t stall again so soon. He told me he had another call in the vicinity - "If you are in trouble, just whistle".

Apparently, (as explained by the technician) the ECU software is programmed in such a way that when you are driving and get a major error like this, the car goes into safe mode, turning down all settings to a safe threshold, to allow you to get to safety and it does all it can to keep the engine running. Once you reach your parking place and shut down for a long time, say overnight, the car goes into a sleep mode. And then when you restart after a sleep mode with an existent major error, it stalls immediately, thereby not allowing you to move the car out of the “safely parked space”. Don’t know how far this is true, but it surely seemed to have worked this way in my car.

I drove the car to the service centre without any further trouble. Explained all this to the service advisor. For the third time, I asked him to check whether my car is covered under the EGR campaign. On earlier two occasions he had denied. This time it shows an 'open' status for the EGR campaign in the system. Apparently, that has nothing to do with the valve and is related to the EGR cooler or something. Anyway, I insisted on a full replacement of the faulty part and no shortcut fixes. I asked what could be the reason for this fault. He said - carbon deposit build up.

They kept the car overnight to check the fault and the part thoroughly and called me the next day to inform me that they have recommended for the EGR valve to be replaced under warranty. But the part wasn’t in stock with the dealer nor BMW India stores. So the part had to be ordered from Germany with an ETA of 15 days. The valve was cleaned and lubricated, but I was advised not to take the car out of station to be on the safe side. Local drives – no problem. So I drove back home and parked the car in its usual place. I don’t use the car in the city much anyway, so it wasn’t really much of a problem.

The part took about 3 weeks to arrive. I got the call and promptly took the car in and the got the valve replaced. They kept the car for two days for fitting, programming and two days of test driving the car for 10 kms each day. It was all good and I got back the car yesterday. The car does feel smoother and the engine quieter. Maybe the EGR was leaking exhaust gases at idle and low speeds as well, I don’t know. Since I drive this car only few days a month and switch from petrol cars to this car frequently, I didn’t notice that the car was sounding a bit rough.

All’s well that ends well, I hope and suppose. But this incident has certainly dented that feeling of invincibility and bullet proof reliability that this car had built up in my mind over the past 4 years and 50,000 kms or so. It has been super reliable till this incident. I just hope there are no more hiccups as I intend to keep the car for many more years to come.

Btw the total cost of the part to the company was about INR 16,000 or so which was covered under warranty. My only out of pocket expense was Rs. 2,000 for the emergency assistance, which should have been covered by the company. I did request for it to be waived off, but let it go since the technician was prompt, sincere, well equipped and helpful.

Dissapointing to hear about a mechanical failure with a BM engine.
If the SA had replaced the EGR as per the recall (and your request) you may not have had the problem. You must report this to BMW when they call/email with the survey.

Fortunately you were able to sort things out without great inconvenience or personal risk.

With so much emission control stuff on board to cause us grief, the days of EVs are not far away.

I shudder to think how low budget Diesel cars will function under BS6.

An unfortunate event there, Santosh. But as you said, all's well that ends well, I suppose!?

I would say, don't be too perturbed by this incident, as far as reliability goes.

Why don't you shoot an email to someone higher up in BMW, narrating the entire incident. It helps when you've placed your grievance on record and creates a foundation for future incidents, god-forbid.

This explanation does not pass the smell test. I would think that the valve was partially operational when hot, but when it cooled down overnight, it got completely stuck due to the carbon deposits.

In any case, the EGR valve clogging is a common issue in most diesels and should not alarm you about the reliability of your car. It is slightly surprising that it occurred in your car which primarily runs on the highways, right? Usually EGR gets clogged when people drive too conservatively, but it's certainly very hard to drive the 3.0 diesel enthusiastically for more than a few seconds before getting deep into triple digit speeds.

I had a similar issue within 12k kms if i remember right. It was a few days after the first service. My car stalled in coimbatore and had to be towed to the dealer there. They immediately diagnosed it as an egr valve issue but even after a week of replacing it the error remained even though the car was running fine during their test runs. Had the car brought to navnit in bangalore and they managed to get the error sorted. I was told that egr valve issue crops up if u fill dodgy fuel. Anyways didn't happen again till the time i sold the car, thats was after adding 60k kms after this incident

Yes, mostly highways. I understand that the EGR valve opens mostly during highway drives and when the car is cruising and stays closed at city speeds. Is it possible that my car being run predominantly on highways meant that the EGR valve has stayed in open position for relatively longer periods leading to build up of soot and carbon?

I didn't buy the 3.0 to drive conservatively . I like to get into sport mode and make full use of the engine and chassis' prowess whenever I get the opportunity on wide six lane highways. In fact the last drive was quite brutal, if I am allowed to say so. I am also using BMW's diesel additive for 1 in 3 tank fills and generally tank up at reputed and good bunks only.

Just wanted to post an update after the EGR valve replacement. The car has been performing well without any further issues. The engine is smooth on idle and at higher revs as usual and feels pretty normal. I drove the car around town for a few days before venturing out on long drives with the family just to make sure that the car does not throw up any more errors after the EGR valve replacement.

I drove the car on the 19" Yokos + BBS wheels for about 2.5k kms before switching back to the tubeless Pirelli 18s. The 19s are very good no problems at all. Surprisingly the comfort factor never took a hit and they are nearly as comfortable as the 18s. The fresh Yokos are very silent and those 275 rears just seem to provide some unreal traction when you floor the pedal. The BBS wheels have just transformed the looks and I just can't seem take my eyes off the car!

The reason I switched to the 18s is that NH4 is undergoing widening right now and there lots of diversions with haphazard speed breakers and potholes. I do a lot of running between Bangalore and Belgaum and the roads are not in great shape. I don't want to risk it with these 19s. Also I had a drive to Sirsi coming up in December, and we did drive to some pretty remote places. Roads were terrible in some sections with road works going on etc.... Drove on rock beds for kms together. Really good decision to swap the 19s for the 18s for this trip. The tubeless Pirelli 18s have taken a lot of abuse in their stride. I don't know how RFTs would have fared in this situation. The crossover body style with enhanced GC has been very useful. Even the AWD was put to good use this trip with some mild off roading prowess needed to cover certain sections. Spare wheel + inflator + wheel changing tools kept my mind at ease.

The diversions on NH4 were very bad after the heavy rains this season but are getting better now. So I will be slapping the 19s back on soon. Can't tolerate the stock alloys now .

Close shave
Had a close shave on the highway with horses. The highway at Harihar does not bypass Harihar town and takes you inside the town for a few kms where the road turns into 2 lane. I was following a two wheeler and there was a small herd of horses (maybe 3 or 4) just standing beyond the shoulder of the road almost out of sight. A lorry was coming from the opposite direction. I wasn't showing any inclination to overtake the two wheeler and wanted the lorry to pass. But the lorry blared his horn just as he neared us and it startled the horses and one of them jumped on the road. Luckily it jumped behind the two wheeler, otherwise the rider would have been in serious danger with a lorry on one side and me right behind. I couldn't veer right as the lorry was approaching. Hard braking was also not an option as there were vehicles behind. Instincts took over and I veered right slightly, but veered back quickly into lane, braked a little and I hit. What seemed like a major body impact was actually just my left ORVM hitting the poor horse's face. The mirror cap came loose and fell on the road and the glass hanged down held just by the wires. I must have been doing something like 60 to 70 kmph and that saved the day for all of us (horse included). It was impossible to avoid the hit. I stopped and inspected for damage. There was no other impact except on the ORVM. I managed to slot the glass back into it's position and complete the drive.

I had swapped the OEM mirror caps with carbon fibre ones from Aliexpress. Came home and put the OEM ones back on. I wanted to order the same carbon fibre ones as they looked really good. I recently got a mail from Navnit Motors about some year end discount on accessories so decided to check with them first. They are quoting 45K for the M Sport caps and this is after 30% discount . Ordered a set from AliExpress costing some 5K. The last set was quite good and held up pretty well in our hot conditions.

Agree with you and @GTO wholeheartedly - if it was a BMW, then it at least needs to be a six banger! Yes, the cars like the Jetta or Octavia are so much VFM that upgrading from them needs big $$$

I am in one such dilemma, my Jetta is 6 yrs / 55K KM's done, still runs like a charm, but the itch of an upgrade is something I am unable to keep myself to... would have taken if not for the COVID situation that doesn't allow us on the road or perhaps there are sweet deals coming in the used car market, only time would tell.

On your need for power - would the ECU of a X35D be suitable, assuming it shares rest of the parts with the X30D?
