the VAG COM scan got a reading of 120...I believe that is mg/h...what ever that is, at idle

Sorry....what ever you call the intake section where the CCV Hooks uprdkern said:What's a throttle body?
What are the MAF readings? Sometimes the readings are different than expected, because the air flow is different than expected. How many miles on this puppy?
Also, it's a chore to read. Putting in line feeds at paragraphs and such makes for easier reading and understanding.
I have been gathering all my service records for the potential buyer and while scanning in some of the major ones I noticed that the vacuum hoses were replaced during the last major repair. I would post the entire report but at this point I am actually more interested if anyone thinks that this even qualifies as a limp mode or if this is something different.l_c said:Bassewitz ... I'm no expert but it sounds to me like it could be some type of vacuum issue. Not sure whether that means, in the path to the turbo actuator. You may need to set something up that would allow you to monitor the MAP (actual) vs requested, right after initial start-up of the engine. The system goes into limp mode because something's not entirely right.
I don't know why, but my limp mode problem (on my 2002) had something to do with the EGR valve (replacing it fixed my problem). [ Replacing N75 didn't fix my issue. ]
I wouldn't assume that the door chime has anything to do with the limp mode. I guess it's possible, but I wouldn't assume that association because I know that those darned microswitches in the door lock modules are prone to not work (after a while). Larry C
I just heard back from the buyer of my car. He owns a shop that fixes fuel injection pumps and turbos.bassewitz said:I have been gathering all my service records for the potential buyer and while scanning in some of the major ones I noticed that the vacuum hoses were replaced during the last major repair.

Thank you everyone for your input.
Not hard on it at all... drive more, worry less!werdna said:Related question on this: is just cycling the ignition switch while driving otherwise bad for the engine? My owner's manual ('03 ALH) makes a big point of not bump-starting the car, but warmed up and turning at 2k rpm might be a different story. Any opinions?
The one time I've needed this, I idled it, shut it down, then used the starter to bring it back and let it stabilize at idle before picking up the load again. More than happy to hear I'm being paranoid here!
Hopefully got a final fix on my mysterious overboost / limp mode problem -- Tomas cleaned out quite a bit of caked sulphur from the intake area. After a little testing I'm unable to get it to fail once warmed up at high RPM's, where before I could get it to replicate pretty well on my 100 mile commute when punching it hard above 70mph. It also would fail when towing up steep grades with heavy acceleration.Thorne said:Per Tomas Sport Tuning it was the N75. If that turns out to not be the fix, I'll update this forum.
. It will do 75mph, but cannot accelerate up the hill, even at WOT, like it used to. I have verified all is well on the intake side. My next thought is some sort of restriction in the exhaust. Thoughts?
