Today it is really pouring rain. Anyway, my 300D all of a sudden felt like it lost all power, thought I'd have to pull over. I read some posts about the EGR valve maybe being screwed up. How can I test this? Nothing's been done to the car recently and it's not smoking at all except at startup. How can I access the turbo to sort of spin it a little by hand and check for play in the thing. I can't hear so I have no clue if the thing is squealing or anything.
Is there a wastegate on this turbo set-up that might have hung up open? Could heavy rain cause problems? I wouldn't think so with a diesel but.... Same fuel I've been using for months. Car is used mostly at hi-speed 70~85 80 miles a day. A/C is not working so it's not the compressor kicking in. Any advice greatly appreciated.
