I'm driving a 1999 A6 2,5Tdi. Now the car feels like 15 horsepower and max 3,000 rpm.

The only fault in VAGCOM is 00575- Intake Manifold Pressure: Control Limit Not Reached

I have checked al what http://wiki.ross-tech.com/index.php/00575 says.

-Hoses seems ok
-Pressure Unit for Turbo Charger seems ok
-Solenoid Valve N75 workes
-Air filter is clenaed
-Airmass sensor is changed


The strange thing is when i messure on block 011 with VAGCOM it says before engine is started 694 mbar and 1010 mbar

when I start the engine the values are 1120 mbar 1000 mbar


The 694 mbar seems stange. Normal pressure is about 1000 mbar som maybe the intake manifold pressure sender -G71- is bad?

Had been a lot of help if someone could messure block 011 for me and post the values.

Sorry for my norveigain-english ..

Did get that same code on my Jetta 1.9TDI. Turned out to be a bad/cracked/old vaccum line from the N75 valve to the waste gate.

I'm assuming the car dropped into limp mode after getting that code? Can you clear the code?

In limp mode all the lightes in the tiptronic will light up? This happens if i pull out the cable ftom the airmassmesure.

The car is not in limp mode (lightes in tiptronic don't shows). Yes I can clear the code, but it comes back fast.

Can maybe be a cracked/old vaccum line, but I have checked all of them visualy and they seems ok.

Still thinking the 694mbar pressure is stange when motor is'nt running

Have you tried <a href="http://www.tdiclub.org">TDIClub.org</a> (US)or <a href="http://www.tdiclub.com">TDIClub.com</a> (DE)? They have forums that have TDI specific discussions.
