Some 15 days ago my GT had a sudden loss of power while driving.
Boost could not rise more than 70kpa,i had no CEL !
Car was driving smoothly even so and after i shut down the engine for abt 10 mins and restarted verything was fine...140kpa!
Today,the same thing happened...after i stopped for 5 mins i restarted and boost was there again.
I've done a bit of forum search and the only thing i could match was a leaking gasket between turbo and intake...but the interminent symptom does not match.
Can you please help a bit on what might be the problem...?
If not a bad gas maybe a blow off valve,wastegate..?
Thank you in advance !
