    Can anyone tell me what this part of the coolent system is so I can source the gasket/oring to fix the coolent leak, its the housing that is bolted to the engine with 2 10mm bolts and has a sensor within it

    Car is an A3 8L 1.8 non turbo 1998 Sreg

    Try a vw dealer if they are closer, normally cheaper too.

    Admittedly for a s3 but got mine from Gsf this week and was £5.90 +vat for the housing and o ring (there housing usually get brittle and brake up) where as audi wanted near double that ;)
