Warning light
Whilst overtaking in second i got carried away and accidentally red lined it to 7k rpm. After this an amber engine light came on the one that means half power available take it easy and get your engine checked. The light has now cleared since the engine has been of. Is this just precautionary or i should be worried. Car is 135i btw.
Thanks for any replies |

Your choices now, take to the dealer and have code read, or drive the car until it duplicates the problem, which might not happen. I would take it to the dealer. I would hate to be overtaking a car and loose all power. You might also consider buying a code reader. I have one and its the best purchase I have ever made for the car.

I had pretty much the same thing happen. About a month ago I was heading up to some land of mine in the mountains to meet with surveyor and was just started the climb up a grade when the instrument panel lights up like a Christmas tree. I get the ½ engine light and hardly any power. I pulled over and turned off/on the car but still had the ½ engine light. I went back home and took my truck up. When I got back home from my journey I started the car and it ran fine. I called the dealer and they wanted to look at the codes. Turns out I had a cylinder 2 misfire. They swapped the spark plug, coil and coil wire with cylinder 4. Problem has not come back. I questioned the SA about the HPFP issue and he told me the computer only stores the last couple of codes and it was a cylinder 2 misfire that showed up. It could be the HPFP but shows up as a cylinder 2 misfire. I am sure our car has many sensors/checks going on and it only takes on sensor burp to mess the whole system up.
