The engine warning light has been flickeringm on and off at its own mind some time now,

The garage is telling us the ECU is giving too low voltage to the Lambda, and the ECU is to be replaced, 600Quid!!The car is , of course, still running, and fine, ,but I still wanbt to know if anything serioud can happen.

Sorry, sorry!

My English should improve! ( and there is a lot to be done!)

I would be quite sceptical of that diagnosis. It's a big step to condemn the ECU, what is the evidence against it? (fault codes) Did they say which probe was getting the low voltage - or is it a probe giving the ECU a low signal?
