Have a decent shop check your alternator. Mine had fried a component inside - can't remember what atm.

Oh, I guess it was a resistor in the rectifier plate.

I had it repaired, and the issue seemed to go away.

Since then, I am using a custom made 130 amp alternator (for my electric steering and such). No more problems...

The alternator is an known good alternator.

Could the engine earths, alternator earth effect its control ?

Serial number of the unit?

So where is this written please?

Lloyd

On the bottom side of the ECU.

Ok S/N: 10228

While online, with the engine off, reduce the running voltage to 14.2 (down from 14.4) and click burn. Wait 10 seconds, then start the engine.

Ok thanks

I will try tomorrow.

Ok it worked but it needs a quick press of the accelerator before the battery light goes away.

Thanks Dimitris hopefully this will be reliable as this car is my daily
