The Random E46/ZHP Question Thread

Rubber sound dampening material under coupe rear bench: how important is it? Is there something I should replace it with instead (e.g., Dynomat, etc.)?
I pulled the backseat and that rubber is completely shot--pretty sure a mild sneeze would destroy the remaining pieces...

Seems like everyone just removes it and leaves it out.

Thanks, Vas. The mobile search wasn't yielding anything useful. It was absolutely disgusting under there :eeps

You could clean out that shitty rubber dampening and install dynamat there. There is a DIY out here which shows you all the places in the interior where dynamat can help cull NVH.

Have you checked the Lighting forum? http://www.zhpmafia.com/forums/forum...hp?53-Lighting

I'm new to the forum, and barely have the right to comment, and certainly shouldn't complain, but as informative as this thread is, and I read it daily, why can't the questions be asked in the most appropriate technical forum section? This is a more technical thread vs. the "What did you do to your..." one. I find myself saving individual responses in my own bookmarks, and a good Search tool will, eventually, help me find other tidbits. Just a question - thanks for your consideration!

Is there a zkw stamp on the lens?

Also what does the label on top of the headlight say?

If the bowls are burnt, remove the back cover and the light bulb and look inside. If it is burnt, you will notice the bowl to be not chrome

I have a roll of dynamat in the garage if you want to throw some in there.

All ZHP sedans that have Xenon came with ZKW's from the factory. The question isn't whether it's ZKW, the question is if a previous owner has replaced them yet. By the sound of it, they have not. As others have said, the surefire way to tell is by removing the bulb cover from the back of the headlight as though you were going to change your bulb and look at the projector bowl. If you see burn marks, you have ZKWs that need to be replaced.

If you plan on keeping your car for a long time (several years), I advise you to replace them with something entirely different, not another set of ZKWs, otherwise it will happen again.

Found a dent on the A-pillar (right side). Given its location, are these PDR-able? luckily paint did not chip

Never know until you ask. They can do some pretty amazing things if they're good..,
