Hi,

back from a maintenance service + update of my firmware (2.42 as i can remember). Garage said they have look for the wastegate retrofit option, but did see it thus no opportunity to select it :-(

With new firmware, sound is a bit louder, and car feel more powerfull. Nevertheless it remains very linear. I'm close to my initial power setup now i think. But i will always have a doubt if my car was less linear before (the famous turbos "kick ass").

I'm wondering if it is usefull for my to contact the french national after market service to explain my disappointment, and also wondering if they could have more precision with this lag fix option...

If you have any thoughts, please tell me...

Top speed is the same on my car 250 kph before and after the SW update.

One of the new things on my car is that my parking lights flash when I unlock the car. Also when I turn off the DSC I have a new icon (see photo I attached).



It feels to me, that the new software BMW has upgraded us to - keeps the wastegates open at idle - when before they were closed(I think). This gets rid of that WG rattle... but also introduces more lag when we step onto the gas pedal.






I hate the way my car feels/drives now after the SW update.

I had the software update recently and now have that same DSC symbol that you show.

I agree as to your observations:

Stock - the car is less responsive and has more turbo lag than before the software update.

Tuned - The car feels the same on a tune as it did before the update.

But there is an issue with ignition timing recovery when tuned.

New software update from BMW is just stupid and reintroducing the same turbo lag issue this thread originally was founded on many years ago.

Hi Ilma,

What do you mean by: an issue with ignition timing recovery ?

How do you know this and what is it? Do you mean after the engine starts to ping/pre detonate? ???

Also curious about the ignition timing recovery. I had the last software update and my car has been doing strange things ever since and nobody has figured out a solution.

This is a 3rd to 4th gear pull on 98 octane.

3rd gear is showing timing is maxed out, but when I shft into 4th notice how the timing doesn't recover back and stays pegged very low.

Before the BMW software update, timing for both gears looked nearly identical.

NOTE: This is not engine knock....the timing is just not rising back to where it should.

There seems to be something different in the shifting logic with the new software that seems to be conflicting with the tune.

Ilma - That is very interesting about the timing advance and recovery. I know my flash tuner over here in Germany (Marcel at www.ms-chiptuning.de ) has told me that BMW's latest SW has some anti-tuning features. This can cause problems IF your tuner hasn't sorted the tune out. This is why Marcel always does a data log before and after a flash. There is also something different in BMW line coding for the throttle plate adaptations. Marcel told me my car's new SW and another 135i he had tuned the day before with a PPK (perf power kit) had this new anti tuning SW.

I think BMW is getting wise to some of the tuning tricks on this motor. It just means your tuner has to be SMARTER!

No.....that looks like boost oscillation due to throttle closure.

Most common cause of that is bad boost control.

If that is stock then I would take it to the dealer and ask them to reflash the software.

EDIT: Just saw you run a Dinan tune......call them up. They probably haven't adjusted their software to the latest BMW update. They should be able to confirm this.

My car is currently in for wastegate rattle like empty cans. They replaced the wastegates but it still rattles like before. Sooo... any of you know if they replace the Turbos am I going to get same exact Turbos and so a pointless exercise or are new BMW Turbos improved\better than the old stockers? I am on the fence and pretty disappointed the car wont run for too long without any issues at all. I had given up on the annoying rattle after two "fix" trips, but since I am almost out of warranty in a couple of weeks, I decided to see if they get fixed this time around. Just wondering if anyone knows if new Turbos at the dealer have a better build or do I just have to swallow hard and accept this rattle will always be here with this car? It rattles worse than the 335d and that's saying a lot.

Vase - what year is your 335i ?

I thought (I am by no means an expert!) that the early ('07 or '08's)335i's had a thin actuactor arm on the wastegates. This would and does wear and cause the dreaded rattle. BMW changed the wastaget deisgn to a thicker rod and acutactors that actually can be replaced seperately from the entire turbo.

It sounds like you have an early 335i and need the new-er (upgraded) turbos w/wastegates. As for the insides of teh snails(turbos) they flow the same from what I understand.

I have acess to a speed limit free autobahns over here and 98 to 102 octane fuel. All the empty autobahn driving I did - could not improve the crappy BMW SW update that I got on my N54. Things only got better after I got my flash tune with 380 PS. I must have driven with BMW Sw update for about 1K miles for I got my tune. Once the flash tune was loaded - even just with the engine idling - I knew my old motor was BACK. All the same old rattle sounds and ripping performacne when you crack the throttle open! I won't let BMW touch my car again.

June 07 335i with 28K miles. Maybe you are right. Rattles like a mofo. Yup even after replacing waste-gates still rattles. Oh BMW we love the cars but I am also sick of the endless issues that keep coming back like a snake that keeps growing new heads every time you cut off the head.

So maybe I opt for the Alpina or M3 next time. Also, I think that the F10 is a nice-looking car (if it only wasn't so expensive).

If you think that marshmallow stars are "it", you should REALLY try out alcoholic beverages. I recommend a 2004 Remirez de Ganuza.
Hi Meyer,
how are you?
Finally I have new turbos in my car, I requested my dealer not to update the software. I have v32.x with conversion valve.

Do you know if is it necessary to update with new turbos?

My car is n54 December 06, are the performance the same with last sw?

Thanks a lot

I'm fine, just planning to get an M3...

I think BMW's procedures tell to update the software, although I doubt it is really neccessary. Performance is fine, but I don't have the all-latest software...

I think not, I have pulled the trigger on it. Not because it is faster, but because of the refined chassis and braking. You would need big money to make a 335is make behave like an M3.

turbo lag

I have a '08 335I --in 2009 my software was updated for the turbo lag and immediately I noticed the difference. The car was quicker and smoother, gas mileage improved and it sounded great.

A couple of weeks ago I brought the car back for a problem on another thread--comfort access does not work all the time (been working on this for the 3 years I have had the car). New handles and antennas were installed and the car was updated for software.

My comfort access still does not work BUT to boot, I regained turbo lag and lost the raspy sound of exhaust, lost .3 MPG and the tranny is no longer silky smooth.

Anybody have ideas?
