Today while driving down the freeway I went to accelerate past a semi-truck. I didn't down shift, I just pressed the accelerator. As I did this, this light came on:



I stopped immediately and looked in the manual. On page 133 it said, "Lights up in yellow:
Full engine power no longer available
You can continue on your journey, but moderate your speed and exercise due caution. Have the engine checked as soon as possible."

I then continued home which was only about 4 miles. Once home, I used my OBDII reader to check for codes; it didn't have any. There was a note about a misfire.

Anyone know any possibilities about what might be wrong?

The car runs fine and I've noticed no loss in power. It didn't make any funny sounds when the light came on and isn't making any now. The only indication that anything might be wrong is this annoying light.

I will call the mechanic tomorrow. In the mean time, is there a way for me to clear this fault?




Just for the record:
2008 Mini Cooper S
Manual Transmission

 

No one? Not even to tell me to stop posting things you've already hashed out?

 

One way to clear the ECU is to disconnect the battery for a couple minutes, usually just the ground side. There might also be code scanners with a cel clearing function --- try your local auto parts store.

Best way to prevent this particular cel, when punching it, is to ensure there's minimal load on the engine --- RPM's are high, like 3 - 4K. This assumes your engine is in good condition.

 

Thank you oldbrokenwind.

 

OK, it's at the mechanic. I have to wait a day or two because they're booked.

They gave me a Hyundai Elantra as a loaner. Life sucks at the moment.
