2015 F10 M5 (콜드에어인테이크, 애프터마켓 머플러 장착)의 LTFT와 STFT 값이 비정상. 양쪽 뱅크 간 연료 트림 편차가 7-10% 이상으로 나타남.
MAF 센서 문제로 추정됨. 애프터마켓 인테이크의 MAF 센서 하우징이 OEM 하우징과 다른 직경을 가지고 있을 가능성 높음. OEM MAF 센서는 특정 튜브 직경의 체적 유량(Q = 유속 x 단면적)을 기준으로 프로그래밍되어 있으므로, 새 인테이크의 MAF 하우징 단면적이 더 작으면 동일한 공기량에 대해 더 높은 유속을 감지하게 됨. 이로 인해 ECU가 연료를 과다 분사하게 됨. MSR에서 해당 인테이크용 MAF 센서를 별도로 판매하는지 확인하거나, 애프터마켓 MAF 센서를 구입하여 새 인테이크에 맞게 튠 받을 것을 권장.

I did more track days in my E60 than all my other cars in the past combined I would hazard a guess at. So many fond memories. My advice, put a decent set of brakes on it, I ended up with 12 Piston Calipers and 400mm rotas with all the track days I did and it really transformed it and the confidence it gave to the car.

250k miles on this one. High mileage cars appear to gravitate towards me. I went to see this one courtesy of Bolidemichael of this parish. I've wanted an M5 for a while, and this one intrigued me because of the mileage and the fact that the then current owner had done all of it bar 30k! It was either going to be worn out and a waste of time, or well maintained and worth a shot. Luckily for me it was the latter. My high mileage 911 had just slightly broken on me yet not actually failed to proceed (detailed in its own thread). I needed another car while I sorted that out and this fitted the bill

Regarding the biggest bill, I think I will still never ever get over the £800 oil filter housing gasket for my Gallardo or the £600 exhaust clamp (4 required!)
