We have an 08 Touareg with the 4.2 litre V8.

What is your question?

A little over 2 weeks ago an oil pressure light came on. We don't go to the dealer because we've not had good service there and I have never trusted them. We took the car to out local shop and they checked oil pressure and said it was on the upper end of factory spec. They called VW of America and they suggested changing the oil pressure sensor. They did. It didn't fix anything. They said they thought it would be best at this point to take it to the dealership. We did. The dealer has had it for about a week and a half and they called yesterday to say we have no oil pressure and the pump needs to be replaced. The estimate was $4500
