I have a problem with mu Engine Management light on my GT diesel. It keeps coming on randomly and putting the car in to limp mode with limited throttle and no turbo. I have had the EGR valve replaced and had the Turbo sensor changed. It happens cold, hot, fast slow, motorway and country roads. There is no set pattern for this. I pull over restart the car and it drives fine then. The light stays on and goes off eventually. I am getting a bit worried incase i have to replace the ECU. I have had the car remapped however the problem happened before but rarely but since the remapping it is happening nearly 4-5 times a day.

Does anybody have any suggestions? has anybody experienced this? This is so frustrating when taking over cars on B roads.:mad::confused:

+1:thumbs: as for frequency after remap is usually down to higher parameters ie boost/fuel line pressure,so if fault is in cars working ,remap just make it more sensitive:thumbs:


You're ECU is not broken, who did your remap? get the remap removed as it's no good ...
if some thing is wrong in the cars working you cant point finger at remap until diagnosed:thumbs:
