coastline taxis Posted July 17, 2011 Posted July 17, 2011 ok driving along loads of power and good mpg. Then engine light comes on and car goes into limp mode. plug it in and no faults present. Go to live data and all appears normal. then when the car is ready it will put the light off and run normaly. have taken snapshot of live data when car is running normal at 3000 rpm and compared it to snapshot of when the engine light is on and the data is the same. Now while were pretty compotent at using the scanner now. the ecu does remain a bit of a grey area so my question is could the ecu be faulted and put the engine into limp mode and take it out of limp mode or is it programed to only do that when its notified of a fault of one of the sensors Quote

It was showing I was slipping thwe clutch at 3000 revs (I wasn't but it thought I was) so shut the car in to limp mode and then after 10 mins or so allowed me to proceed. Be Warned, the time-out delay gets longer each time. Cheers Gary Quote
