After 112,000 miles our RS4 turned into an idling jet engine over the weekend so it seems one of the PCV has given up and will need replacing. I believe the parts for the left and right side are as follows but where's the best place in the UK to get them? I can only find some on eBay from Lithuania and would rather try a UK Shop if possible. I'll give the local dealership a call tomorrow but wondered if there was anywhere I'd missed as they seem to be scarce at best.

Just after a major service too. Great timing

Thx
