My front splash shield is trashed, and I'm looking for a replacement but there is apparently a difference between the one for an automatic transmission (8K1863821) and the one for a manual transmission (8K1863821B). My car is a manual. I'm looking for an aftermarket or used part and wonder whether it's possible to use one off of an automatic. The new Audi part is obscenely expensive.

I don't know for sure, but the splash shield only extends under the engine and not as far back as the tranny. The mounting points on the frame s/b the same for either auto or MT6. The one on my MT6 is flat - nothing special for the tranny. I would risk it. You can always drive without it, too. It keeps the engine from getting whacked by road debris or dirtied, and there are conflicting and inconclusive discussions on whether it helps aerodynamics.

 

I did end up getting a splash shield off of an automatic, and it fit fine.
