Took my S2 out tonight for the first time in about 6 weeks, it last ran perfectly.
For some strange reason I now have very little boost. My gauge is showing about 0.5 bar. Had vagcom in the car while i was out and read the codes there were 4 i think. So cleared them, drove off and had full boost in second gear, changed to third no boost.
Checked the codes again when i got home, they are;
00540 knock sensor
00513 engine speed sensor
Have checked the MAF sensor connector/plug and the WGFV connectors all fine.
Anyone have any ideas?
