Just of late my car has been a ****** to fire up , This only happens when the car has been left for atleast 6 hours , Ive charged the battery and it isnt temperature ( weather ) related It turns over as normal just takes maybe a second or so longer than normal, Any ideas anybody?? While playing with vag com ( no faults found ) i noticed the coolant temp. read on vag com shows around 100 degree and the dash shows 90. this surely isnt the problem is it?? I mean a faulty coolant temp. sendor??
