Problem with a SEAT LEON 1.9 TDi FR

SEAT LEON 1.9 TDi FR 67K

Lack of power when under load, no fault codes stored. After switching the engine off and restarting, the power was restored until the fault reoccurred. Suspect fault due to sticking variable vanes on turbo.

The fault was cured by adding Diesel Turbo Cleaner and Advanced Formula Diesel Treatment into the fuel tank. The car was then taken on an extended road test and has been running fine since.
