Codes P1372 P1252 P1253 and the fix
In case someone else has this. My Mk1 turbo gave the codes
CODE STATUS
---- ------
P1372 .............................. 62
P1252 .............................. 28
P1253 .............................. 22
No check engine light. Turbo boost intermittently dropped down under 100% load. VTG turbo linkages were changed at the dealer. Left one was loose and did not operate the vanes properly. Very inexpensive fix.

I'm seeing a p1373 with similar turbo loss (intermittent). Any idea on what your part numbers, or parts were for your case? Were these the actuators/solenoid (I think the part no:9A110530803) or another part?

I think they are the linkages for the variable vanes. I just had mine replaced since the Indy said they were almost falling off which may be why I was getting the 1372 code. We will see. The part numbers I believe are 99712312470 and 99712312370. One for each side.

Those things also are pretty prone to rusting and getting stuck/stiff.

I was talking about the actuators and their linkage arms. Porsche even issued a service bulletin on how to lube them because it was becoming an issue. You can access them to check (and lube) pretty easily with the rear end on ramps.

Don't even need ramps, just lay down and reach up to the turbos. Easy to access. Which lube do you need to use? Might do mine.

Thanks for the info. I threw P1373 on Saturday and boost would drop under load. Lubed both actuator rods this morning with high temp grease. Only required two short pulls on a desert backroad before boost was nice and steady under load. Feels smoother on boost, too.
