Thanks to everyone for their various comments. I greatly appreciate them. Here is an update for any additional thoughts.
As I mentioned, I need to stick with a 2000 AWD V70 for various reasons. So my dilemma is limited to sticking with this specific car or asking the dealer to undo the deal from August and then I’d get another one. So is it better the devil I know.
The following is my best understanding of how they explained it to me.
They replaced the air mass meter and the wiring harness. I forgot to mention in my first post that when the replaced the oxygen sensors they also replaced a fresh air pipe with a redesigned one. The PCV system is now all new. They believe that the problem was oil was not condensing properly in the PCV system and was affecting the wiring harness and the rest of the PCV system. They think this might have been due in part to the original design of the replaced fresh air pipe and possibly the prior owner not doing regular oil changes and maintenance.
They think that the failed ETS was unrelated and not beyond normal for 50,000 miles (they think that it was a poorly built ETS that these cars came from Volvo with and mentioned similar problems with the ABS system).
They’ve driving it for 82 miles and run it hot and cold in the shop. Everything comes up okay. They understand that I’m going to have my own mechanic look at the car and their reports and give me a second opinion before I decide whether to keep it or not.
It seems to me that I have a 50-50 situation. I have a brand new PCV system and ETS on a vehicle with 50,000 miles and an unknown service history. I could get another car with an unknown service history.
Any additional advice? (I know, drop the AWD and get a FWD, but that’s not an option for me).
Yours,
Mark
