It's just water and mud from driving through big puddles!I don't really need a VAGCom because i can see which sensor it has broken (the filter pipe is resting on top of the broken sensor and snapped the cables off the top.The filter pipe should sit higher but the bracket that holds it up was crap and broke
If ETKA was working on my laptop I'd tell you in 5 minutes Is there not a visible part number on it?
