Old thread revival.....
I've been told the check valve on my brake booster hose is failing to close under boost so I'm after a new one.
However, this is proving very difficult as the guys at my VW Parts Dept cannot find the correct part for my engine.
When I give them either the 1K0 612 041 BM or GM revision part numbers they are not listed against my BYD engine code, infact when they show me the parts catalogue on their screen there are no parts with the three pipes coming off the valve, only ones with two.
Also, my one that is failing doesn't have the very short pipe coming off to the right like the one in the photo above has.
Do all Pirellis / ED30s have the BYD engine code?
Would any BYD owners be able to check what part number they have on their cars for me please? It would be greatly appreciated.
