I finally found the green temperature sensor yesterday on my 2.5tdi cabriolet. On most posts on the forum and on google, everyone says its near the battery, but we located more in the centre of the engine bay (on the 2003 diesel).
Anyway, now i have found it, where should i buy it from? eurocarparts, ebay, audi?
anyone got the part number? are they different between petrol or diesel cars?
