AGU 1.8T IDLE ISSUES

Post by lukas1zn »

HOWSIT GUYS ...

okay firstly when i accelerate i can hear air sucking noise , its pretty noticeable , did check for boost leaks but could not find any . I have a boost gauge and on hard acceleration it holds on 0.5 bar boost .
secondly after i accelerate hard and put load on the engine , the car starts to act like its in limp mode , when i stop it feels like the car wants to die . if i switch it off and start it again , the idle drops right down like it wants to die and then picks up to 1000 rpm and holds there .
in the morning when i start the car put it in reverse and come out the driveway and then try to put it in first gear every time i press the clutch in to change to first my rev gauge goes up to like 2000rpm for couple seconds and then drops back down to 1000rpm like normal(without touching the accelerator) .
ran a diagnostics on vagcom no fault code and no mil light on .

man if someone can at least push me in the right direction i will really appreciate it .

Serious vacuum leak somewhere.
Check all the boost and vacuum hoses again.

What's the condition of your MAF, You could clean it and see if it makes a difference if its does then replace it. That gave me endless issues
