Hi everyone, new to the Z3 fraternity so looking forward to some good advice and help. Recently purchased this little beauty, it had been stood on a drive for approx 12 months. Ever since passing my test many many years ago, I've always wanted a soft top car so when I saw this on a drive looking sad, I plucked up the courage to knock on the persons front door and luckily they agreed to sell it. Came with a mountain and I mean a mountain of paperwork and an original Z3 manual, which is more like an encyclopaedia because its that thick. Not had to do much at it at all, passed its MOT 1st time with no advisories, such a lovely car to drive. One thing I do need to replace is the DISA unit. Priced a new one and (as you all will know) they are quite expensive, so would anyone know where I could possible get my hands on a second hand one, or is it possible to replace the diaphragm as believe this is what will have failed inside the unit. Also, is there anything I could use to give the rear window some life back into it, as its quite dull at the moment. Thanks

You used to be able to buy a kit to rebuild the DISA valve from eBay. I assume you still can?
Greygate plastic polish (another eBay sourced product) makes a world of difference to those old plastic rear windows.

Local supplies of one of Disa membranes dried up a year or two ago..you can still get the rebuild kits from the states cheap enough. Alternatively there are a few rebuilt ones on eBay. It’s not as straightforward a job as you’d think to do yourself.

Ahh right ok, so failing the rebuild kit would you have any idea where I could get a second hand one?
