I bet you felt awful pulling over like that and allowing the 640 to "win". My father told me a similar story in 1980 when he was in his 320i and the Mustang was forced to pull over due to a mechanical failure. Bummer.

Hey, guys, driving home today(no WOTs, just regular driving) got half an engine with 29cf and 29f2 codes. I have new plugs with less than a mile, stg 2+ aggr with VRSF dps, 7" FMIC, ETS CP with TiaL BOV, AFE stg 2, BMW PE with 2nd cat delete.

HPFP has been replaced about 10k ago and the car has just under 22k miles. What could that be? I read that the code is thrown sometimes if tune has been altered, but it was not. Any help is appreciated, I cleared it for now.

Sounds like you might need a HPFP.

My car is in at the dealer right now.
Ran rough, half engine, threw similar codes.
This will be the 4th HPFP in my car......

I'm starting to hate my e90.

I had a similar issue. I removed the Cobb AP and I am now running the stock tune and I don't have any issues. I am glad I didn't go crazy replacing parts and wasting money to fix/replace something that was not broken

^^ thank you guys. So should I check Injector for the third cylinder since that is the one throwing the code?

Car is still under factory warranty till Dec 22 and than CPO, but I'm not sure if I will have time to take all the mods off before that.

From this, it sounds like you're clearly having something fueling related. Recently my car was having trouble cold starting and constantly running lean, no matter what tune (from my PROtune to the Stage 0/Stock Map). Turns out I needed 6 new injectors since I had the original ones in from 2008. Fuel trims are always in check and it's now running super smooth.

If someone has INPA, then can check if the injectors are operating within acceptable range. If you have Warranty (especially the original manufacturer warranty), get that car in a dealer ASAP so you could possibly have any repairs covered.

Any idea if the dealer you're going to use is mod friendly? Some dealer's in the Tri-State hate mods, others don't mind as they're clearly not responsible for any of the failures/have been installed correctly.

Thank you. Decided not to risk it and coinsedentially I had enough free time at work to remove and put stock intake/DPs/CP and reflashing the EVU back to stock. Car is at the dealer now, we'll see.

I dropped it off at Tenafly, last time I did it the car had Vanguard exhaust, intake and suspention and they did not say anything.

Good luck. I've used Morristown/Open Road and as long as the tune isn't installed, they've never given me any trouble.

Tinkering around with DashWare this morning, I added a new logging parameter to my usual track layout, Load Req. & Load Act. Not sure if it adds any value to the video, but I thought it might be interesting to see. All the positional data in the vid was logged with my AiM SOLO GPS, but I used the COBB for all the engine data.

I'm also working on an overlay with the default logging parameters, I'll post an example once I go out and do a pull. My temps are unusually low in this video for a track day because it was only 37 degrees outside

Very cool! Is the Cobb data loaded into DashWare after your run, or somehow combined during the run?
Also, I couldn't tell if you were using your paddle shifters - or were you in S mode.
Thanks for sharing!

Yes, I load the .csv files from the AiM and the COBB into DashWare along with my video file and sync them after my run. DashWare lets you do data files from multiple sources which is nice. You're right, I used the paddles for every shift. I keep the car in DS mode on the track.

Probably best to replace all 6, especially if the 2 failing ones are on separate banks

I'm sure the answer is in this thread somewhere, but I can't find it :-(

Anyone know if you can use the troubleshoot menu on a 335i other than the one the accessport is married to?

Thanks!

Gonna guess yes, since you can use the troubleshoot menu without it being married to a car.

I've done it at the track with my AP to read other people's codes. Very helpful.
