[s-cars] Boost issues

[Pasqualoni, James E]

Taka,

This sounds like it may be a thermostat failure.  Oil heats up b/c coolant
is not running thru the engine.  Coolant does not appear to be too hot b/c
temp sensor is in reservoir.  Coolant can not circulate through the system,
but builds pressure as the temp increases to the point where something
(radiator neck) breaks.  This happened to me years ago in my old 91 100.

Hope this helps.

It was a beautiful day today so I decided to take the Audi to work..... BIG
mistake. Couldn't see more than 13psi peak, 10psi continuous throughout the
gears, everything seemed okay at the time.

I didn't think it was anything serious until I got a CEL and the oil temp
(?!?) started rising mysteriously, while the coolant temp was not.

Proceeded to limp the car off the highway, got the car to a safe location
when steam came out from underhood- still coolant temp is around 2/3, oil
temp went to 150C, shut the car off immediately.

Found a broken radiator neck, will be replaced soon, but what to make of the
oil temp rise? The CEL was from the temp sensor, that's all I've found so
far.

Any thoughts? I wonder if there was some sort of problem that was limiting
boost, or if I just have a leak somewhere.

AAA Plus is great- free 90mi tow!
