I'm constantly refining the how to and FAQ articles. Here are some recent videos added to the turbocharging article http://www.myturbodiesel.com/1000q/turbocharging.htm - they help show what a runaway is.

This is why I do not suggest removing the anti-shudder valve/intake flap. It's not likely but if it does happen severe engine damage could result. If you have a manual you could put it in high gear and step on the brakes to stall the engine but if you have an auto you can't. And of course, the first and foremost thing is to drive safely and keep the car under control - no point in crashing the car or getting killed to save the engine!

This is a bad CV joint that I found - it was causing a vibration at idle when in gear. It's unusual for an axle to be the cause of such strong vibration when the car isn't moving but it does. http://www.myturbodiesel.com/1000q_how_to/b5/CVboot.htm The writeup is for a Passat (also works on Audi A4 and A6 of the same generation) but the general tips on CV boot repair are the same across really any car.

crap

Well im new here and have been reading up on all the forums and so on. Taking a closer look at my 2000 beetle 1.9 tdi the anti shudder valve has been removed along wit the actuator that works it. Was looking for possible boost leaks cause my engine light is coming on with maf, egr and glow plug faults i think the glow plug faults are from leaving the key on so long for the code reader. MAF is new and there seems to be alot of oil in the innercooler and leaking from the base of the egr, making me worry about turbo seal and hence runaway. Does anyone have any ideas about the leak as far as maybey unhooked actuator on shuddder valve or base seal on egr. it seems like i am leaking oil but im not sure if its just drip from base of egr i changed it when i got it and put 4.5 quarts now its kinda low again. Is there any way to know how much oil in innercooler is too much.

A little oil in the intercooler is normal, maybe a half pint? I don't know but a lot of oil could be from a leaking seal. A leaking EGR weep hole is common but not normal. The glow plug faults are a common problem, it's probably the harness or plugs. Glow plugs are really cheap and new ones should work better too so I'd replace them all.

will the glow plug code come from key being left on so the code reader can communicate with the ecu, cause the glow light had gone off before it read the codes and can bad egr cause maf code

No on glow plug.

Bad EGR - maybe. If the anti shudder valve was removed, the EGR may have been removed. Can you take a picture of the section right before the intake manifold showing what you are talking about?
