Complete Parts diagram for E46

I need a part but don't know what it is, and when going to these BMW parts sites , they ask a zillion questions and in the end, its not the part I need. Is there an online reference where I can look through parts explosions and figure out what I need, and then I can go order it(I'm a visual person)

1999 323i sedan - I need the rubber/plastic part that runs along the bottom of the front windshield that has vents in it, and has holes where the wiper arms are attached. ITs a combo of plastic and rubber. I thought it would be windshield trim, but noe of the online BMW parts companies think that way. Any help would be appreciated to get me headed in the right direction.

Thaanks,

Thanks - I found it again - had it bookmarked but lost it - I love that site.

The part I need is as mentioned below, called Windshield cover - mines all cracked and falling apart - I had water in my interior last rain and thinking this is maybe the cause. Hopefully.

Thnaks,

Thaanks,

Just like BodyMan mentioned, it's a Hood Cowl / Windshield Cover.
I have them in-stock.

Hi guys, a new member here, so please forgive me if I have overlooked any protocols in my first post.

I've got the same issue with my windshield cover cracking and flaking off... probably happened when a previous owner replaced the windshield.
Any chance if anyone knows where i can source a windshield cover in Melbourne Australia or if anyone out there will send one down under?

OP,

Check your hood drain in the corners where plungers go...also, under the cabin air filter (in the housing) there are also what I believe are drain holes too. Make sure they're clear of debris. If they clog, then water from the cowl will back up and get into car potentially.

I replaced mine and that stopped my leak and I vaguely recall thinking that when cracked it bypasses hood drain and would find a way to 'bad places.' I know some have had it go into ecu...expensive!

Also, my cowl didn't fit tight against the window in all spots, but not an issue...the water infiltration happens when it's cracked...not from the 'seat' between top of cowl and windshield.

Easy diy! Doublecheck all your gaskets are overlapping correctly around cabin air filter housing and other 'walls.'

For this part, although what you mentionned above will AMPLIFY and ACCELERATE the problem, look at my post from an other tread, I figured this out after ALOT of testing with a garden hose and the carpet removed...

If that is the case, replace that black plastic trim around and under the wiper arms. This part has a seal and when it dries over time it does'nt seal any more.

Water then goes underneith and collects in a fold that leads straight into the cabin and it leaks along the fire wall on the inside. It does'nt help that the wipers tend to push water right in that area on their was down.

It gets even worst in winter because, water freezes undneith and lift the rubber clear off the glass plus, it can get dammaged when you scrape your windows...

Before you replace the part, you can check by lifting the carpet were it goes up the fire wall and put a garden hose on your windshield, if that is your problem, you'll see the water comming down the firewall. you might also see some rusty runs on the fire wall, also a good indication of this problem.

Hope it helps.
