Right filter every time
Went on my A4 B8 2.0 TDI at 71k miles. The media feels dense and the end caps are properly bonded rather than glued on thin. I changed it with the oil at the same service interval. Result is throttle response feels crisper than it did on the clogged original. Will be back for the other side.

Correct fit, sealed properly
Ordered this for my Q3 8U after the original gave up at 135k. Two minutes behind the glovebox once I had the tabs released. The media feels dense and the end caps are properly bonded rather than glued on thin. Result is shifts are smoother now the transmission has clean fluid and a fresh filter. Cannot fault it.

Genuine quality for less
Cross-referenced the OE number against my 2011 Q7 4L before ordering. The media feels dense and the end caps are properly bonded rather than glued on thin. The old one practically fell apart coming out; this went in cleanly. Result is oil pressure comes up as quickly on a cold start as it always has. Happy to recommend it.

No leaks, no fuss
Bought for a 2014 A6 C7. The media feels dense and the end caps are properly bonded rather than glued on thin. The old one practically fell apart coming out; this went in cleanly. Result is throttle response feels crisper than it did on the clogged original.

Good pleat count
Replacement for my 2009 S4 B8 3.0 TDI V6. Dimensions matched the outgoing filter to the millimetre. I changed it with the oil at the same service interval. Result is throttle response feels crisper than it did on the clogged original.
