Hi, 

Looking for a bit of guidance with these errors. They do clear on restart, with no issues.

 

Basic OBD2:

P0299 (Pending) - Turbocharger/Supercharger "A" Underboost Condition

 

Engine:

19225 - Turbo/Super Charger Underboost

25710 - Turbo/Super Charger Underboost

 

On investigation the Turbo Actuator socket was damaged, believing this, I replaced it and did the adaption. We believe the one we replaced wasn't original, due to the fact the circlips were missing off the end of the sjadt. However went for a spin today and error comes back.

It appears to happen on a return journey after the engine has warmed up a second time, usually when I'm about to overtake. But, if I try to replicate I have no luck ever !

 

Next plan of action was testing the vacuum lines, maybe they're losing pressure. We had a look and they appear okay.

 

Following that, pressure sensor. 

 

Any ideas what else to check?

Air pipes or intercooler pipes loose or split possibly.
