Has anyone noticed slight discoloring on their rear valance from the exhaust? I have a 2.0 SLine, and the exhaust stains don't seem to come off 100%. Anyone know what the nest cleaning product to use for the valance? The SLine trim pieces are all flat grey plastic(?), and I don't want to use anything too harsh that would scratch or discolor it worse.

Any help is much appreciated!

First time I've heard this but I'm not surprised given how filthy the tips are on my A4. These 2.0's seem to run pig rich.

I doubt you'd have any issues with a good quality cleaner. I'd give the folks over at Chemical Guys a call. They have their ****e in one bag and since stepping up to buy their products, my car's have never looked better.

Simple... Get the Carbon Fiber versions instead!

This check valve and strainer, are they hard to get to and change? Anyone have a diagram?
