I have a Cabriolet with a 2.8 V6 engine, unlike yours it doesn’t have a drain plug on the gearbox sump instead the oil is pumped out through the gearbox dip stick tube and filled through through the same tube, I don’t know if your 2.3 has a dip stick tube but if it has you have you could fill it through this. I would say Stevey Y has the answer though!

Ebay or Audi tradition.

I’m sorry Charlie I don’t know what else you could change but I’ll be very interested in learning what the final solution is. Good luck! Turlough

Thank you Ian, this is what the forum is about, sharing our knowledge and experiences. Well done on getting your Matrix sorted, it’s one of those components I think of with dread every time I put my heater on but hopefully ill never need to change it🤞 but if I do I know there’ll be support on the forum!

Hi Malachy i would concur with everything Gareth has said! Terry.

There should be a label in the boot possibly on under the carpet or in the spare wheel well. It should also be inside the front cover of its service book. hope this helps.

Hi Imran I have a 1997 80 cabriolet which has alloy trim around the wind screen and along the side and round the roof compartment, it was badly tarnished when I bought it and I tried everything to remove it including commercial tarnish remover, it didn’t work! I eventually tried a woodturners wax that contains a very minute amount of very fine grit in it, it worked wonders at removing the tarnish and brought the trim back almost like new. I applied it by wrapping a clean cloth round my index finger, picking up some wax and working it in small circular movements, leaving it for a few minutes then buffing it, not only did it remove 95% of the tarnish but also left a protective coat on the alloy to prevent it from tarnishing again. I have attached a pic of the wax i used, it should be available on EBay or you could try any of the woodturners supplies sites. If you don’t want to go to the trouble of hunting this brand down you could look for an alternative wax but just be careful of its abrasive content, the wax I used worked very well and you wouldn’t want to use an abrasive wax that would damage the finish. The wax I used is called “U Beaut” EEE-Ultra Shine. ‘Hope this helps! Turlough.

I take it you’re asking if you should order some paint in to do the repairs yourself. As with everything it’s your call and a lot depends on how perfect you want the paint work. If the work is carried out professionally you can rest assured a rust bubble or two won’t suddenly appear under the repairs in six months time, plus the work will come with a warranty. In my experience it’s very difficult to get a good professional finish on chip repairs carried out by an amateur. I also have a 1997 dark blue Cabriolet and where paint work repairs are concerned I’d prefer to use a specialist.

Correction! Sorry the cable tensions are not adjusted at the window carrier but where they go onto the pulleys. 👍

I have cross fitted them and have never had any problems, the very early regulators (91-93) may need tweaked a bit but nothing too complicated. They are basically the same item though the frame structure may differ slightly. Worse case scenario you can transfer the motor and cabling onto your own frame though I have never needed to do it. I’m on my fourth 80 cabriolet, and I changed regulators on three of them. Tip! When you install your replacement regulator check you have the cables tensioned reasonably taught but not like a guitar string, they adjust where they connect to the window carrier. Theres no magic wand here, everyday is a school day, take your time and before you dismantle anything take a photo for reference, go for it you’ll be fine!

There are plenty of Audi 80 Cabriolet’s being broken on Ebay.

Well done Greg! The hardest part of the heater matrix is stripping out the dash but once in there it should be straight forward, good luck and keep us posted👌

I see they recommend that “If in doubt, consult a specialist for advice.” I would do that before I buy anything not after! good luck!

Hi Dylan, The only thing that qualifies me in attempting to help you is that I have had many a head scratching session over electrical anomalies in classic Audi 80 Cabriolets. is there any noise coming from the rear left window? If there is it is possibly a broken steel cable or pulley in the windows mechanism, If you can’t hear a motor running then it could be the actual motor, a relay or a broken cable, it may also be the switch in the driver’s door. The windows master switch only operates in one direction, I think this could be the switch or one of the master switch relays, as far as I’m aware there is a master down relay and a master up relay. The first step would be to test the switch, then the relay, then the wiring. Sorry I can’t be more definitive, I’ve attached two diagrams that may be of some help. Turlough.

Gareth is spot on, either refurb it, or adapt it. Sorry I can’t be of more help but please do come back and tell us how your issue gets resolved. good luck! Turlough
