Hey, thanks madmods! Much appreciated
So, I'll try and disconnect the battery and do the routine you described. Is this to reset the programmed ECU and then make it start over again with a "clean sheet"?
How long should this drive be and what revs? Just vary my driving? Some city and some highway?
It is going in for a small service friday aug 23.rd. I'll make sure they check that the tiptronic coolant valve works as it should, even if I'm doing the above mentioned routine.
