Did your car misfire when you removed the tune?

[UndergroundEuros]

yes it did, dealer told me 500.00 to fix it, they said my o2's are messed up and they know it was moded. I'm so fucked now. Think my warranty is gone.

Ahhh...you actually re-installed your Stock downpipes? How did they it was modded? Maybe tool marks on the O2's?

UPDATE: I am just got all six injectors replaced along with plugs, I am picking up my car tomorrow.

I clearly remember when I swapped my plugs about a week ago they did have a strong odor of fuel, specifically the ones that were mis-firing (4-5-6)

This is NOT a DIY, I think injectors are around $300+ each!!! and since I had mis-fires in 3 cylinders they replaced all six....$2,000 in parts alone!!!!!!

lucky you, I fixed my problem I am good to go now!

So in the end was it just that you had your o2 sensors swapped?

[gian p.r.]

Well I had this problem on the mornings and the dealer told me there is a campaign because of malfunction of the Piezo injectors, so I thought they were going to change them but they end up changing the software and a oxygen sensor and till now the car is running great

[UndergroundEuros]

I had this problem and it was fixed under the previous version of this bulletin before the updates and it did not fox the problem. If a bulletin that was done to your car is subsequently updated with a different solution does the dealer do the updated work automatically or does it need to be brogut to their attention?

Hey bro I'm getting misfire cylinder 1 2 and 3...and I changed out the plugs coils and injectors and it still says misfire 1 2 and 3...u think it might be the o2 sensor?? Cuz I'm not getting any codes on o2??

I have a 2006 330XI . . . problem with cylinder #5 misfire . . . I replaced the injectors, plugs, coils, fuel pump/regulator (bitch to replace). It's as if the plug is not there (it is). I swapped the coils to one of the others and still on #5. I don't know what to do . . . when I took the plugs out a couple were pretty bad. The only thing left is to swap the plugs with one of the other ones. #5 is not getting a spark apparently since when I disconnected the coil there is no difference.

I was driving to work and #5 (I think) failed and the car ran as if a coil went bad. But just as I pull up to my driveway, it stopped.

It took a few minutes for the car to throw off a code.

I don't know what else to replace?

This must be the grand resurrection of all threads

I just had cylinders 123 misfire and the codes indicated bank one 02 sensors. I took my tune off and the problems went away. Time for a new tune, but first new plugs and coils since they are due soon.
