Well, where shall I start.... Fuel actuator at first, which was replaced, but problem persisted. Then the air sensor, which fixed the problem for about a week. Then the fuel filter decided to crack, causing fuel pressure lose. Then the fuel pump failed, 'how wonderful.' All these issues bestowed limp mode upon my M5.
Let's not forget, a new battery, a few sliced tyres, and 'oh', my diff's leaking..... Did I forget to mention, I now have a voltage discharge warning!!!!
Should of bought a Nissan sunny........
