I have been having problems with my PDAS switch not working and narrowed it down to no voltage at pins 1 and 2 at the valve block. This comes up with code 34 according to Adrian streathers book.
where is the valve relay so I can test it? I have another 964 c4 so I can swap parts over but at a loss now.

Thanks

The relays are right on top of the pump.

Thank you, I guessed as much after reading up over the weekend, I have swapped this relay over with a known good one so take it that the ABS pump is at fault.

I had similar codes and a new accumulator and bleed solved all my problems. YMMV
