The first probable cause would be the wheel bearings. The problem might be in its infancy, but you might also start hearing it at lower speeds as it gets worse.

The second one is a bent alloy wheel. GTO's 530D ownership report had a member complaining of humming, and later found that it was actually a bent alloy wheel causing it.

Get it checked by your service centre ASAP.

Apart from the issues Vishy76 has mentioned, if there is uneven wear of the treads, this could result in noise from the wheels. Check the tire treads for uneven wear. If there is uneven wear doing a tire rotation may help in reducing the noise, as the driven wheels tend to produce more noise (in this case the rear wheels).

Also as you mention the car has run 28K, the tires may also be nearing end of life, in which case they may need to be changed. From the comments from many users, it looks like the RFTs last maybe 25K to 30K.

Never tried tyre rotation unless the service centre did it on their own. All 4 tyres are new and were changed at around 27k mark on the odo. While changing the tyres, I was told that the alloys are bent. I thought it's more like a money making scheme. Let me get the alloys checked. I don't drive harshly or have not taken the car to potholes rashly. But there's a very little we can do in Bangalore's pot holes and speed breakers ridden roads.

Has anyone tried shops which repair bent alloys or, I am looking at deep hole in my pocket?

Please dont repair alloys. Generally they dont work. They make the alloy round, true, but the structural integrity of the alloys takes a big hit. Because of which next time you hit a pothole, the alloy wheel could shatter, crack or whatever causing an immediate deflation and total loss of control of the car.

A new set of alloys might be expensive but it's cheaper than a major accident

+1 to Nikhil. If the alloys are bent, the best is to replace them. They could be expensive to replace, but that is a price to pay for safety.

I own a MY17 320d sports line. I got a call from the BMW service center today informing that there is a software update for the car and to send it in for the same.

Does anyone know what this could be about. I asked them if it was an idrive update,which I found on bmw.com/update, but they mentioned that its not specific to idrive but a general update for the car software as per the info received by them.

Can anyone throw some light on this

Its something to do with the EGR valve if I'm not mistaken. Some small tweak. They will update the full software of the car. I got a call for my car too, but haven't had the time to send it in till date.

Hi folks,

Im thinking of upgrading my 320d prestige (F30 LCI) with some new accessories. Thinking of changing my instrument cluster to the new digital Multi function display, the idrive screen to the 8.8 inch, and M-sport steering wheel with cruise control.

I contacted bimmer tech USA and they said they can ship the original parts (made in Germany) to me. Has anyone tried their service and how reliable are they? Also, has any 320d owner upgraded their cars with above mentioned parts...if so please do share your reviews after fitting the parts. Will I have any problems with customs in Bangalore as I stay here?

Hi Kiran, I was also contemplating the larger screen and M-sport steering wheel, but did not move forward since I wasn't sure about warranty issues. I am giving the link below wherein "Sail" had installed the steering wheel on his 3GT:

What price have you got for these mods?

Thanks for the link! Just type Bimmer tech on google and see the hompage. They have loads of original upgrades for every BMW out there. I only enquired about the digital instrument cluster which is approx 1 lakh. Plus installation I need to find someone reliable here in Bangalore. Lemme know if you have any good contacts or recommendations.

hello everyone.

it was time to change my tyres in my 320 d, as i have always been using RFT since i bought the car, but recently i ordered advan neova ad 08 r tubeless (for the first time)for my other car and was superly impressed with the handling and grip of the tyres.

as the tyre wall is stiff/hard compared to most of the tyres we get here in india including yokohama india (side wall is good ike rft) i wanted to use the same now for the bmw as well. i always dreamnt of putting these tyres but due to restrictions i dropped my plan, but this time i was committed to get these tyres from abroad and finally i did it.

i am very impressed with over all handling, grip and also the look of the tyre, and the thudding sound from the rear has gone that we get in the RFT, as per me this is one of the best tyre i have ever used in life till date. i completely stand by it, if you can go that extra mile and get these tyres from outside india then i highly recommend you to try this.

few pictures for you to have a look at this beautifully groved tyre:

i am still running a staggered set up though, front 225/45/18 and rear 245/45/18

Hi,

I am one of the recent members to acquire the 320D. This is a December 2013 manufactured Sportsline Variant which I picked up in November of last year. I didn’t make an ownership report as the F30 has been here for quite some time. In fact the facelifted LCI too has been here for more than 2 years. The only thing which could invoke curiosity in the ownership thread probably would be the buying decision. In case of my car purchase it can be read from the thread which I had started last year when I was deciding between the Octavia and the 3’er.

http://www.team-bhp.com/forum/sedans...8-tsi-dsg.html

However in absence of my 3 Series ownership thread I would like to share any updates which may be helpful to others here in the official review thread.

Update with Changing Tyres and using Tyremarket.com:

I got the car with 40,000 kms on the odo. I was told that the Bridgestone RFT tyres were changed at 30,000 kms. The manufacturing code on the tyres is of September 2015. I am assuming that these tyres might have been put on the car sometime after January 2016. I had been facing problems with one of the tyres after purchase. It was leaking air and I got it checked at the regular puncture repair shop. The issue was fixed by plugs which are used for regular tubeless tyres. Two weeks ago I faced a problem with another tyre which developed a side wall damage with a bulge and a puncture on the side wall close to the rim. The puncture repair shop did a temporary fix which was enough for me to drive the car back home and to the new tyre shop at moderate speeds.

I decided to change two tyres (one with the side wall damage and the other which had the punctures in it) with tubeless ones instead of the RFTs. I do not have the Space Saver but for now I have decided to take the chance of always carrying a tyre inflator with me in car so that in case I get a flat tyre I can at least fill up enough air to drive to the closest puncture repair shop. Also my driving is limited. I drive mostly within the city and the annual driving is just about 6000 – 7000 kms.

Since I am going with a combination of old and new tyres I didn’t want to go with different brands and hence decided to go for the Bridgestone Potenza 225/50/R17 in the Tubeless form. I checked with a couple of shops and found that the best price I was getting was around 11,500 a piece. I also checked online and found the site, www.tyremarket.com. It is a Bangalore based company. They allow one to purchase the tyres online and the fitting is done in select cities at their partner tyre shops.

I got the tyres at INR 10,628 a piece on tyremarket.com. I made an online payment. I was also communicating with them on phone. I asked them about the options of the tyre fitting shops in Bombay. The one which was closest to my place was in Goregaon East. Kwik Fix Automobiles who are authorised Bridgestone Tyre Retailers.



These are January 2018 manufactured tyres.




A random click at the tyre shop.


The payment on Tyremarket.com included the fitting cost. I had to pay extra for the wheel balancing and alignment. I was not sure if I needed to adjust the wheel alignment but still went ahead with it as I changed the front two tyres. I had to move one of the old tyre from the front which was in a good condition to go to the back.

With the two new tubeless tyres in the front I can feel a discernable difference with regards to the ride comfort. I am not sure if it just a placebo effect or indeed the ride feels a lot more softer.

The old tyres which are about two years old and have been driven about 13,000 kms still have some life left. I will replace them at a later stage with tubeless tyres as well.

Also I would like to thank a friend and a bhpian Sushil Marathe

Is it advisable to run the car on 2 RFTs and non-RFTtubeless tyres? Wouldn't it affect the stability and driving dynamics of your car?

The tyre width, profile and size is the same for both sets. (RFTs and Tubeless). The difference is with regards to the rubber strength of the RFTs which are engineered to carry the weight of the car in case of a puncture.

However I am also not keen to have different sets for a long time. I'll be changing the RFTs of the rear wheels to tubeless soon.

[RajBajwa]

My 320d December 2013 Sportsline is due for the annual servicing in August. I was trying to look up any information available online on what all elements will the 5th year annual service include. I couldn’t fine much details and hence posting the question here. My car has been always serviced at the BMW service centers. It has clocked 43,500 kms as of date. Also what will be the approximate bill that I will be staring at for servicing the car in Bombay with either of two (Infinity & Navnit) A.S.S. Centers.

Also is it worth taking the risk of going to specialists garages who work on german luxury cars such as Bosch Service Center (Thane) or D.A.D. (Andheri East).

Any inputs will be much appreciated.

Thanks,

Raj Bajwa
