Just bought a 2000 S80 sedan yesterday.

It has a new exhaust, new fuel filter.

Leaving the lot, the engine light came on and it chugged slightly. We drove back and the dealer said the power cleaning of the engine compartment must have caused moisture to get in some how. He did a diagnostic and said we need to replace the number 3 coil perhaps. We drove it 50 miles home, and in the driveway the oil pressure alert came on.

We had driven this to a local mechanic who pointed out the exhaust issues which were fixed. A slight leak to keep an eye on but not serious. He said it was a solid car in very good condition.

But as a Volvo lover, but not a Volvo repair geek, I'm a little freaked out about what could this be? If it's just a coil, that's easy, but what explains the oil pressure alert? Can I drive it to a repair shop, or does this require towing? I've asked one Volvo expert, but I want to be sure before I drive it.
