Hello to everyone. This was posted accidentally, how to delete the thread. Excuse me guys. :(

Check ;
INTERCOOLER O rings
Unplug MAF sensor and take for a spin,(might go better hinting a MAF but no conclusive as might mask EGR issue.
Replace Airfilter and give basic service,
Check to make sure INTERCOOLER is not damaged
Clean manifold and EGR
Leakback test on injectors
Clean Map sensor (fitted on drivers side of manifold)
Clean Boost temp sensor if facelift model
Replace crankcase breather

If still no better T4 for in depth check

Hey Mick, i have some issues with acceleration, so this is very interesting to me, i'll do the basic servis this week (air filter, PCV etc.). Intercooler is not damaged, EGR is quite clean (i cleaned it few months ago), Leakback test done (all good).

Now, how to clean the MAP sensor?
Where is Boost temp sensor? (edit) Ok, this is the sensor on the intercooler hose. As i can see, it is very oily at the moment...
And what is crankcase breather? Is that PCV filter?


Thanks
