01 Turbo - Can only achieve .4 BAR boost?

[aracerx]

Interesting problem that has a few of us baffled. PST 2 shows no codes. all air passages are tight, swapped MAF sensor with known good one/disconnected battery for limp home possibility/install evo diverter valves. should see .7 - .8 bar. ANY suggestions applauded-thanks for you time-Mark

I had this exact problem after the winter, it was the wastegate down on the turbo that was a little harsh, after I put a little lubricant on it and forced the arm forwards and backwards a few times it started to go smoth and I saw 0.8 on the bar meter again :)

I hope you have this same fault. GL :)

Did you solve your problem and if so how. I have the same model and year as you do and unfortunately have the same problem

thanks

Had the same problem and it was the hose (broken) that goes right before the Throttle

I had this problem too. Mine was a mouse that nested on top of my engine and ate through the knock sensor wire. The motor puts itself into a "protect" mode and would not go over .4 bar. Sure there are no codes?

Good luck
