First of all thanks for any help that I receive from this forum. You guys truly are amazing.

Last night I was on a spirited drive when the car threw a reduced power red warning light. It happened under full power. I was able to turn the car off and restart it ok to drive it home.

I just got back from my local shop. They pulled the two codes:

P1372 Valve Lift control, above limit value
P1508 Function monitoring of torque comparison

I did notice the other night when I was driving in normal sport-mode the car hesitated or sputtered under heavy throttle twice.

Modifications to my car:

Cobb stage 3 tune
Full exhaust with high flow cats
AMS intercoolers
IPD plenum

The car has had a history of oil in the passenger side intercooler. This issue has yet to be fixed.

To add, I recently had the battery replaced. I am due for spark plugs as the last ones were put in about 17k miles ago.

Thanks!

 

I have this same issue with my 997.2 TT. I've been told everything from I have a bad turbo to I have the oil level in the car too high. It's still a mystery to me as well. My car has 18k miles.

I also have AMS intercoolers and have had the lower intercooler boost hoses popping off under load. Happened about 5 times until I finally took the car to a shop and had a metal spacer machined to take the place of the crappy plastic spacer AMS provides.

 

I have been told similar things about the oil. My passenger side turbo was rebuilt 2 years ago, but I still get oil in the intercooler.

Fortunately, I haven't had an issue with the intercooler hoses.

 

did anything come of this? im seeing a p1373 (no other codes), intermittently, and have unrelated boost loss (intermittent as well), so I'm curious what your resolution was.
