disconnect the battery..far far easier..can be done standing up instead of a-la-houdini under the dash.

 

Having tried it several times in sorting out my little problem - the definately behaved differently than before. And it also cleared the ECU memory - as before - fault code was present - afterwards the fault code went away until the AFR went odd again.

I can only say that this standard procedure in OZ.

Question - when you cut power to the ECU, how long do you wait for the capacitors to discharge - a minute, hour, day, week?

The easiest way is to be at an aftermarket supplier whilst they have a "Select Monitor". In the supplier/customer relationship maintenance ritual they do it for free

It also ensures the car has no past or present defects stored that the non-technically minded of us were unaware of, and that the voltage generated by the car will not blow the lights I intend to have fitted next weekend..... but that's already mentioned in other threads
