Coolant leak


Registered User
Need a bit of advice here.

I have pressure tested the system on my S4 and it is slowly leaking coolant from what looks like the nearside aux-radiator, im not sure how to get in and have a good look at this and also would this be an audi only part?

Im also getting a leak on my 3.0.

Hope to get it sorted this week and will report back on where its coming from

Turns out it is the aux radiator on the passanger side:( £138+vat from audi, not to bad i thought. Hope to get it fitted on Wednesday night:)
