Been a while since I posted.
So far my headlamps still work.
I had the switch for the interior fan burn through earlier this year or at the end of the last. Fixed it recently for the MOT with a flip switch. I can now turn it off and on which is really all I did with it anyway but I plan to do a more elegant fix in the future at some point.
I also fixed the leaking sunroof. Only took me a few years to accomplish that 🫣.
Everyone kept telling me that they thought it wasn't possible to fix it and that I should just kit it shut or replace the whole sunroof. In the end what worked for me was actually really simple. I bought 20 meters of closed cell EPDM tape something like 10mm wide and 5mm thick and taped that to the glass pane instead of the frame and glued the ends together with a glue that stays flexible and that so far seems to hold up very well, even with frequent opening and closing. I installed some new second hand 80s door speakers. It's a bit of a shame that the previous owner fitted speakers there. Also there appears to be crosstalk so it's essentially giving me mono output. I also picked up a working 7 band graphic equaliser/booster that I'm hoping to pair up with a hidden Bluetooth receiver to get old school looks with modern features.
Oh and the rear reflectors didn't pass MOT so they stuck extra reflectors on the rear 🙁 safety first though 😕

Great to read your update.

I like your idea about the equalizer-amp and a bluetooth module. I have modified a Blaupaunkt radio with a built-in module that allows a signal pass through when not playing. Getting decent sound quality in the Murena is a bit challenging, one issue being that even with bigger speakers, the rear is essentially open which means that the low end "short circuits" back to the rear of the speaker. I think the door speakers will work much better in this respect, but I don't have them, and like you, I prefer not to. I've worked on making a very compact "subwoofer" that fits above the glove compartment...

Rear reflectors are available from Simon, but could you post a picture of exactly what did not pass?

Oh wow a small subwoofer sounds genius. I probably will have to do an overhaul of most of the looms at some point. There's several weird electrical issues and the grounds seem fine for as far as I can see. So for the moment I reckon I'll just lay down a new set of speaker cables to at least solve the crosstalk.

I attached a picture of how the place that did the mot solved the reflectors for the moment. I can't visually see anything wrong with the original ones but the problem is that they don't bounce back enough light anymore according to the measurement tool. Well there's a clear difference between the new reflector and the original ones.. Also, it's not that he's making any significant profit from selling me those so I didn't question his judgement on that ground. When you say that Simon sells reflectors. Do you mean that that square under the reverse lights can be replaced?
