I thought so too, everytime the car gets an oil change, the lag gets worse, but the engine sounds better.
I'm still waiting on the successful resolution of my car's troubles. MASS are trying hard, but we will need to see the regional head of service if things are to happen.
But we're having a very long stretch of holidays here in kerala(weekend+vishu+election day), and that is holding things up.

I really, really, really, really, really miss the car.

The gearing would be 'short' rather than tall in first gear.

you are correct, my bad.

@ripper: still car is in garage? are they working on it or waiting for the regional engineer?

@ripper: Any update on the regional engineer checking your car? I too am interested in knowing why this delayed boost happens and what it's effects might be

The car is still with local MASS, there is now a turbo available from a crashed/total loss swift, that is going to be swapped in to confirm that it is a turbo problem. if it is, and the problem is solved, then we'll talk to regional head.
Fingers crossed, the issue should be settled by next week atleast.

A few Observations From My Side

Hi All, I haven't been too active on the forum ever since my initial ownership thread (primarily coz I was busy clocking the miles on my VDi). I am now at the 9200 Km mark and have had 2 services till date. The observations on the Turbo and other things is given below:

Before 1st Service:
Turbo was insane (probably because the engine was "tight" in the beginning). It used to spool up at around 1900 rpm ( I could hear the turbo whine starting) and go crazy at 2000 rpm. It was great but there was a definite roughness in the engine. Everything else was fine. The car was rattle free and a pleasure to drive.
Mileage: average 16kmpl (40% city 60% highway, all with A/C on)

After 1st Service (at 900 kms):
Turbo was still hissing away nicely and all was well with my world. The car was rattle free and driving really well. One thing that I noted was that at around the 4000 Km mark, the Oil indicator on the dashboard stayed on for about a second after a cold start. I guessed that this is because of the viscosity of the oil having changed over the 3000 Kms. In any case, there were no issues with the turbocharger throughout the 4000Kms after this service.
Milage: Best: 18.8 kmpl
Average 17 kmpl
Worst: 15.6 kmpl (Highway, Very hard driving 120kph avg. speed)
(50% city 50% highway, all with A/C on)

After 2nd Service (at 5000 Kms):
The first few days after the service, the turbo seemed to have lost it's "kick in the rear" feeling and I was quite disappointed. After a few more days of driving the turbo seemed to have miraculously 'recovered' and I was feeling the kick in my backside at around 2100 rpm. Recently (post the 8000 km mark) the Oil light starting coming on again just after cold starts and the turbo effect also seems to have reduced (though it isn't gone). Also the dreaded rattles started in the front right door (I suspect the power window assembly) and the rear left of the car (I suspect the seat belt). Will have the rattles checked in the 3rd service at 10K.

Mileage: Extremely consistent 17.7 Kmpl (50-50 City and Highway with A/C)



My take on the whole turbo thing is that it seems to be somewhat phychological (try driving another "normal" - i.e. non turbocharged car and then get back to your VDi - you'll feel much happier ).
I also feel that lots of people (including myself) will be dissatisfied with the "psychological" explanation and there could be a genuine physical issue which is causing this (i.e. plumbing issues). My last guess it that as the engine loosens up and the kilometres pile up, it seems that the power delivery in the VDi becomes more liner.

Question - as the viscosity of the engine oil changes, does that also affect boost? Has anyone tried to check if the turbo "whoosh" is better when the engine is cool than when it has reached ambient temperature?

Oops, so you are suspecting that the issue could be with Turbo? Im keeping my fingers crossed too. By the way, i had escalated the issue to the regional head and i was supposed to receive a call from them this week. I havent received anything yet so far and i will also try to follow-up from my end to see if we can arrive at a solution. Thanks Ripper.

Engine oil light going out after a sec of cranking is normal, this is due to change in viscosity and the oil contamination. Run an engine flush at 10 or 20k interval and this will disappear for a while. But really nothing to worry.

Regarding the turbo woosh, i think you are right to an extent since most of us get used to the power and then slowly the urge for more starts. Things that can be checked is to keep a tab on air filter health, air pressure, fuel (IOC regular works for me well) and then the air pressure. I havent touched the plumbing till date. I check the health by listening to the whistle of the turbo while reving (sounds sweet at nights).

With my 195 65 14 tires i have noticed that couple of pounds less and car feels less enthusiastic as well as the mileage drops by 1 kmpl.

Once in a while stretching the engine and long runs on highway do help and seems to make a hell lot of difference to the power delivery of the car. Just another reason for a trip to me

More than viscosity i feel the grade and the quantity matters, keep the oil level at F or lil below F at cold and only in cold should you check and the car performs the best.

WRT temperature, cooler the climate better these engines perform. I feel there is a perceptible difference during winter and late night runs in Bangalore climate. But funny part is if am doing long trips after the car has run some 100 kms (even in peak summer), i get a feeling engine really performing well (esp the turbo pull).

@BBT- i get what you're saying. but in my case, the boost was proven to be only 2psi at 2000rpm and peak boost came at 4000rpm, that too a paltry 11psi.
also- you yourself have said that your boost is now coming at 2100rpm. thats how my car was too, in the beginning. initially, I thought the same way as you did, and drove on. Most swifts i've driven seem to be getting a late boost. and they get later the more they have done on the odo. In my case, the daily "race" style driving seems to have caused things to happen earlier.

@bala- no problem! we're all helping each other.

The reason for the delay is , the impracticality(from the MASS' point of view) in ordering an expensive turbo just to check if it is faulty in a particular car. in case it isnt, they are stuck. so we had to actually wait for a total loss swift diesel to turn up.

Jaggu: Totally right about stretching its legs on the highway once in a while and getting the kick back. I questioned ripper to no extent all the time we spoke on the phone that the kick seems less, its coming at 2100 rpm bla bla. But on a recent trip to goa and back with a run of around 1500 km the vicious kick was back although at 2100 rpm but the tension starts building around at 1900 and everything is back to normal. Mileage though is hovering between 17 to 18 on the highway with 120 to 140+ speeds.

One more thing i have noticed is after i bled my clutch like you asked me to, before the goa trip the clutch was perfect, now the pedal seems a little hard. Gear shifting is butter smooth though ? is this because of the hot weather in mumbai or something else ? the car has run 8000 km.

BBT: I ve noticed this one thing about getting the vicious turbo kick back. Clean the air filter every 1500 to 2000 km.Atleast i do it and there is a lot of dust accumulated even in 2000 km.The kick increases after this cleanup.Try it out once.Also one more thing i ve noticed is.If u keep spooling the turbo all the time in the city, the kick reduces a bit.After that u drive slowly for sometime and then jam the accelerator and again the vicious kick is back.
During night driving on the highway, whatever u do , how much ever u spool the turbo the kick is always vicious but during the day driving on the highways the car seems to get tired kinda feeling.

Okay Sorry for one more post but i forgot to mention this.
Jaggu, do u get a mild vibration on the accelerator/steering when the car is picking up from say 3rd gear at 1700 rpm or so and till around 2400 to 2500 rpm after which it stops?

I ve been facing this since around 3 to 4 thousand km and i gave it to Spectra to check it out and they said everything was normal ? Do u get this one too ?

Swift VDI - Sep 2007.
Got my 35k service done yesterday.

Changed the Coolant, Gear Box oil, Engine Oil (including oil filter), brake oil.

Coolant: Castrol has one that reads "For turbo charged engines". Was using this until I recently found that they have a "heavy duty coolant" also. The operating temperatures mentioned in the heavy duty coolant are better than the "For turbo..." one. Hence this time used the heavy duty coolant. This comes in a 3 litre can. Used 2 litres diluted with mineral water.

Engine Oil: Castrol CRB Plus (with synthetic technology). API CH4 rating, 15W-40. 3 litres. I usually change this every 5k kms (with oil filter).

Gear Box Oil: Castrol has 90W oil "For turbo charged engines" with anti foaming technology. Used this. 2.5 litres. I usually change this every 10k kms. This time it was 15k kms.

Everytime I give it for service, they add the "wiper wash fluid" and charge me Rs. 11.84. I normally add shampoo (50ps/Re.1 sachet) and then water. Before leaving for service yesterday, topped this up and gave it. In the evening while collecting the car, found that this was added in the bill. Guess its defact added. Told the Supervisor that I had just topped it up in the morning. Got a reply that they test it and hence they top it. I got a 50ml concentrate (packed Maruti Suzuki) free !.

Got the Intercooler cleaned. The Supervisor told me that they clean it with petrol. The cost is Rs.350. Wasn't charged for it.

The blower was cleaned and I was charged Rs. 240.

Had the OE tyres changed to Michelin Energy XM1 tyres (185/70 R14) on the day of the car delivery. Done 35k kms and I expect it to last another 5 - 10k kms. I get the tyres rotated every 5k kms (including the spare). These are currently filled with Nitrogen. I find that topping up once a month is good enough and the pressure loss isn't that much.

FE is between 15 - 16.5 in city. Best I've got is 17.3.
Long distance, worst I've got is 16 and the best is an unbelievable 25kms. Usual range is between 19 - 21kms.

Regards
Ravi.

Guys! Just confirmed. Its the turbo. MASS just called. Gushing about how the car is flying after the swapped turbo. Phew! Atleast now, i have an answer. Now to find out why this happened.

@rippergeo - Congrats!! So your boost numbers were right after all I hope they replace the turbo with a brand new one under warranty.

Great. Please post your inferences and also the statistics if possible (boost pressure, fuel injection). Im kind of confused as though the issue reported by both of us is extremely similar in nature, the boost pressure readings from tech2 were different. In your case, it was evident that there was no turbo boost happening, whereas in my case numbers seem quite normal. Appreciate your assistance Ripper. Thanks
