Help with replacing trim....

Hi - has anyone tried to replace the triangular trim between rear passenger door window and quarter panel glass (black gloss piece)? For some reason the piece on the passenger side is fine but drivers side is badly corroded, I have taken a look but cannot work out how it comes off????.

Also can anyone recommend where I can get a replacement (tried A8 parts but they can't help - apprently its a common problem so the cars they break always have corroded pieces).

On a related note, I'm also trying to find a replacement passenger door mirror. The unit is fine but the chrome cover is scratched badly - searched and searched on-line with no luck (also tried A8 parts but no luck), so any help appreciated (along with clues of how to replace - I'm a complete novice to the world of DIY car repair!!)

I can't understand why they used alley for this piece, but used a black plastic and therefore corrosion free trim on the "B" pillar.

The picture from EKTA suggests its just a pop off item. You could always just pull it off and see what happens! If successful let us know as I am in the same boat.

I think you have 2 choices. Get one from A8Parts and repair/respray or new from Audi.

Also in the same boat.

From what i can remember Ian mentioning - i think you have to take the whole top part of the door off

I'm sure he'll be along to verify shortly...

Thanks for this - I was about to charge in hoping it would pop off (that could have been an expensive learning curve!!). I'll hang on and wait to see what Ian says......

okay - so tried to see how I could remove the trim as when washing the car at the weekend a piece of paint actually flaked off leaving a horrible white powdery mess behind

It turns out that you do have to remove the top section of the door trim as well as the door card by the looks of things as the fixing sits about 2 inches below the door sill. Frankly the thought of pulling the door to pieces without much of a clue as to what I'm doing put that idea to rest.......so plan B - repair in situ

This actually turned out to be pretty straight forward - in fact the more coroded the trim the better as the gloss finish is sprayed on to a sort of rubbery/plastic coating a couple of milimeters thick on top of the aluminium - what seems to happen is that water gets between this and the aluminium and 'blows' causing the white powdery effect and 'bubbling' behind the paint. Where its coroded the paint and rubbery stuff can be just pinged off with a flat blade leaving the aluminium exposed below.

Mine was only gone in the corner so the rest had to be sanded down to the bear metal (this rubbery finish won't let you get it smooth and feathered in to the aluminium no matter how hard you try as it just has an 'edge' to it) so I sanded thru grades 240 all the way down to 1200, primed, then painted (3 coats) and then laquered (another 3 coats)

Now, with it in situ you can only get to the visible part above the rubber seal on the window, but if your patient and careful you can mask it up and get the paint just below the door seal so cannot see anything even on close inspection.

So, 5 hours start to finish in elapsed time - in total only about 2 hours work (rest was waiting for each coat to dry) and bingo - nice shiny trim again
