hi ,just had mafless remap (speed density ).on my 02 bug,since getting it back ive noticed errattic idle when cold ,once warmed up it settles down to 900 rpm .also when warm and i turn on anything ,ie lights or heater revs go up to approx 11oo and stay there .thanks ,ian

 

I have the same issue, so will be interested in the answers.

 

Who is doing the mapping, same guy or place ? if so, if these faults are after the remap, suggest talking to the mapper to fix

 

yeah will have to take it back, i just wondered if i can do anything my self ,as such a pain to get car there and to leave it there and try to get transport home .
