Heater box foam sheet

[Rusty]

Can you get a replacement stick back foam sheet for the heater box seal flaps?

This would be interesting to know, as since my heater matrix went and was replaced a few years ago ive had sporadic little pieces of foam fly out at me from my heater vents.

I would also like to know if there is something to replace the old deteriorating foam with. I've got to do something before the box goes back in.

I would use something like this, glued on with high temperature adhesive

Ensure a good adhesive is used, I replaced the foam inside and the damn self stick adhesive must have failed. I barely have any hot air coming through in the winter

There is a black insulating felt padding that is used by Mercedes Benz for insulation purposes. It has an adhesive backing. I have used it to refresh a couple of heater boxes that have lost their foam insulation for the flaps. The part # should be 000-989-23-10 or 001-989-23-10. It is about 70mm in width & comes in small rolls. If you know any of the techs at the MB dealership he probably has some in his tool box.

I just re-did the flaps in the S2 today.
I used the foam backing on replacement roof lining velour. Peeled the velour off and used spray contact adhesive.

I did mine using a reasonable quality felt and contact adhesive, had no problems with it and it should not break down like the foam in the future.

This looks about the same as that used by skull. Thoughts -

Looks the same that I used.
Works chop chop.

You need a sharp blade cutter to trim the new edges but the rest it's dead easy.
The big work (more of a pity work..) it's cleaning the old one to have a clean surface.

Any chance of a new link for the foam for this job?

Also what make of matrix are people using? I don't want a cheap one that will leak in a years time!

I used this stuff https://www.ebay.co.uk/itm/201181704646

I wasn't that impressed with the fitment of the Nissen matrix, given the choice go for a Valeo as that is what my original was.
