2.5l manual Jetta 140k 2011
New oil leak. Dealer reports it as vacuum pump but i haven't checked yet. I see that it's a common problem and there are replacement gaskets and I'm leaning towards that option. BUT, could replacing the vacuum pump improve air conditioning in any way???
this car has always had trouble creating cold with the ac. It's been checked and refilled with refrigerant twice, no known leaks. It does cool down a bit when reved up and moving down the road, but it's warm at idle. Are they related on this car? Some have done the delete and report no ill effect on breaking, but what about AC efficiency?.
