I'm looking for help diagnosing a problem we are having with our 2004 PSD I'm fairly sure it a turbo but thought I'd pick yawl's brains and see what you think. We left last Friday for a short camping trip and about 10 minutes into the trip I started thinking that the old girl was running a bit sluggish. At first I thought maybe it was just me since it's been since last August that we've had the camper out. When we got to our first hill it was clear something is wrong. At first I noticed when I put a little pedal to her there was a strange high pitched sound, much different than the regular turbo whine and it was sporadic and eventually went away. There is clearly a lack of power as I could barely maintain 45-50mph and I could do 65 up this hill and had plenty of power left before. The only other symptom is that at high RPM's and under load there is a loud "gushing" noise from what sounds like the turbo area. I thought it might be a pipe had come off but I cant see anything obvious. I don't have a boost gauge so I don't know what she's getting for boost but I'm not getting any CEL's, she's not smoking, she seems to be fine at idle, low RPM and all the other T's and P's are fine. I'm probably going to take it to the dealer but thought I'd check here and see if anyone has any advice.
Thanks!
