When I first bought my beloved M5, it was amazing. The previous owner told me he had the infamous "Drivetrain Malfunction". He had the plugs, coils, fuel pumps replaced under warranty.
Performance Mods include:
ESS High Flow Catted Downpipes
Acrapovic Exhaust
MSR Intakes
ESS Stage I tune
All seemed great for a while...Then this happened:
Great.. Now the troubleshooting begins...
Downloaded codes and get this
Reset ECU to stock and problem eventually came back so it wasn't related to the tune.
Decided to pull plugs and check for wetting.
Bank 1:
Bank 2:
Hooray! Leaky injectors..
After biting the bullet and ordering all new genuine injectors from FCP, I was on the website looking around and noticed the OE Bosch injectors were in stock at 1/3rd the price. Sweet, ordered those and sent the genuine's back. Before I sent them back, I did a side by side comparison to make sure I was good. I will note, I went with the original EU5 injectors.
Yep same same... Kind of weird that there aren't any caps to keep the o-rings from expanding... o well. On to the replacement!
Teardown
Finally got those buggers out.
Back Together!!
Reloaded the tune and all is well so far! About 1000 miles down now going strong!
If anyone has any questions, don't hesitate to ask! Fell in love with this car all over again! Thanks for reading.
