Hi Febi supply the mounts and a shed load of other parts as O.E., I found that out when I bought my oil level sensor, Audi wanted nearly £200 with the VAT so I bought a Febi sensor from my local spares shop for £67 and guess what the Febi item was exactly the same except someone had ground the VAG/Audi logos off of the casing, the only thing left was all the casting numbers which matched perfectly, the guy at the spares place told me they do it all the time as they are not allowed to sell O.E. marked parts in their packaging, so if you want to buy a badge engineered part in the right box for twice the price +, knock yourself out.
Steve.
