Anyone else having second thoughts due to the new software

Potentially good news for those that have been affected in that case.

Incidentally, over here in the UK, Evo's long term test 335i Touring had to have both turbos replaced at 16k miles, due to the wastegates "sticking open". BMW's official response to Evo was that less than 10 turbos had been replaced on 335s in the UK, although there were a few actuators replaced too. One car had the fault at 8k miles.

They did ask for people to actively report any faults to the magazine, so no doubt they'll probably be more aware than most of any potential problems. They also love the N54 :smile:

Thinking about it, the fault was classed as "premature wear". So it does seem odd to possibly create more wear by having the wastegate opening and closing more than it would do otherwise, if that is what 29.2 did?

Well, since my car was built in Jan and let's say I had v29 from the factory...how could the rest of you not have v29 as well? :wink:

The wonders of the written word means I can't read into the context of whether the winking smiley is supposed to indicate humour or irony or something, so apologies if I've completely misinterpreted what you've written.

Wasn't there a 29.1 (and presumably 29.0?) as well? Unless you've been back to the dealer since for any reasonable work, you won't have 29.2 I would assume.

The problem seems to stem from 29.2 specifically, not the v29.x generation of software as a whole

[looking]

We need facts and stats to clear all this up...has there been no real figures yet?

[ChrisK]

If there was a problem :iono: it seems to get fixed with v30.

[MadisonOne]

would a turbo boost gage answer the question about turbo lag from the software updates? I know our cars don't have said turbo boost gage, but isn't this information available through the OBD?

[Dr_Jones]

I guess the takeaway is that if you are going to mod it...Dinan only. My plans were to get the dinan remap after a few thousand miles (for better highway crusing mileage :-) ). After seeing this...i think not.

Im a little concerned about the carbon buildup as this will lead to rough running/misfires over time. And with a direct injected engine there isnt a really good way to clean the intake valves as fuel is injected downstream. I know i should search this but is there concern over oil vapor from crankcase being vented back to intake?

This is a known issue on the direct injected 2.0TFSI motor i drive at present (one of the reasons why im not interested in owning my car off of warranty).

Why BMW why? Engine of the year my ass...haha

So you don't actually have a 135i yet. I'm not sure which version of software I have but my 135i has absolutely no lag off idle. I can shift to 2nd gear at 10mph and still have enough boost just off idle to not bog the engine. In other words.. it's VERY smooth and has torque right away. If someone can point me to the instructions I'll go out and verify which software version I have right now. This thread seems comical when I think about how great the car actually drives.

Update: I have 01.06 = 79.50.81

I think an oil catch can should take care of this.

SO how much boost is unsafe for this motor? I was spiking at 21psi and holding at about 16psi to redline in my 1.8T GTI for about 80K miles with NO ISSUES AT ALL. Why would a $40K car have problems? :iono:

[aus]

Stock boost is around 8psi with max safe boost around 15psi. I think Dinan runs around 13psi.

How much boost and engine/turbo's can take is not a matter of how much the car costs.

And V30 does not seem to fix anything, and many dealers don't even have it.

Because the $40k has higher compression, spools quicker, and would be pushing outrageous hp and tq figures at 21psi. The 135 has power lower in the power band than the VW, so while your gti might make decent dyno queen numbers from boost spiking and creeping, it wouldn't be usable like the 135's. What type of torque did your gti make at 21psi?

[Dr_Jones]

Cant speak for the 1.8T, but i think stage 2 (APR or REVO which would run peak boost in that neighborhood) numbers for the 2.0T are around ~280 lb-ft to the wheels. The k03 turbo is also puny and cant keep up the boost at higher revs. It spools fast though. Maybe it makes 230-240 hp at the wheels. The useable torque band is actually pretty wide....no comparison to 135.

People are making amazing power with bigger turbos on the 2.0T motor...too bad its going to the wrong wheels and the owners are without warranty. Check out the VF engineering RSR.

257wtq
dyno queen.....LOL.

[pheller]

My Jetta (1.8t) makes ~ 340 wtq, spikes to ~ 26psi, holds at ~ 24.5.

Also no problems with the engine in 70k miles.

I agree, always admired the 2.0T. My only problem is it being attached to a FWD platform.

Regarding the post at hand, I messaged my CA, he's checking with his techs. He hasn’t had a single complaint regarding lag on the 1's or 335's he claims.

[ChrisK]

Let's get back on topic :biggrin:

Has anyone gotten v30 software installed yet?

That's because most of the peope complaining are speculators who don't have their cars yet.:biggrin:

I noticed the lag the first time I really stepped on it. Not that it's a big deal, but after reading all the reviews about the 135i having ZERO lag, and coming from a fast N/A car, I had decided that all the journalists were smoking crack. There is definiatly some lag with these cars.

[0002s]

BTW...how many of the "laggers" don't have there oil temps up to 210ish? I definitely get some low rpm lag until the car is warmed up. Then I get good pull from 1400ish on.

[taiheung]

my mechanic said the moment you roll it into BMW for a service / warranty issue they'll update your software anyway - so it doesn't matter anymore when your build was, you'll eventually get the v81 and then you're screwed!

[ChrisK]

Sorry guys...I have v29 and I still have zero lag :iono:

I am interested in v30 only for my alarm. :wink:
