CEL, Running fine? Here are the codes...
2003 A4 1.8t Avant Quattro, 84,000 miles.
My CEL just came on. I recently completed 80K service (oil, timing belt/water pump, air filter(s), plugs).
Ran VAGCOM and here are the codes:
I'm just starting to troubleshoot this, but will I damage it by continuing to drive the car until I figure it out? Any input appreciated.
Thanks in advance.

Found the leak... now, part #?
The leak is a fractured check valve at the rear of the valve cover, in pretty tight quarters:
Now I just need to figure out: Will any check valve do? Or do I need a specific part #? EuropaParts.com: In-Line Check Valve - 058905291K - OE Aftermarket
