According to Bentley, the aircons with non regulating compressors have the thermostat like i have. Just wondering if any aircon experts can advise how i would connect this one in its place instead. Its got a thermistor as opposed to a gas thermocouple. There are three leads, red, green and black. I assume the black will be ground - is this going to be needed? The old Ranco A10 thermostat has only 2 connections Thanks

Thats pretty serious Shaun, thanks for posting, great picture, certainly gives a lot of detail. Did you have new metal welded in? How did the body shop ensure all the old sealant was removed?

looks like the sealant had failed in a particular spot - pulled off the trim and cleaned out the crud and rubbish in the channel. It seems the windscreen may have been refitted prior to my ownership (some 20 years back) and not too neat at that. The sealant seems to have separated at a point along the screen hence the entry point for water just by the DAB aerial. In the interim i've use some black gasket sealant and pressed the trim back into place. Didn't seem to have any water in the car after the rain last night fortunately, just some water condensing. I'll leave it open for a while to ensure its sealed ok and then refit the soundproofing and carpet. Thanks to everyone for the input. I'll be looking to get the screen replaced at some time and will see if there's any rust around the frame that needs welding or other treatment. That way at least any old sealant will be completely removed

The Passat B4 seems a good option then - i like the idea of more light in the car, creates a feeling of more space. Sorry Matt, just for my understanding do you mean a Passat glass in a Mk3 mechanism? Thanks for the heads up to Leo GS Burley - i'll drop him a note and see whats available

Anyone know whether a Mk5 sunroof would fit? Or maybe just the mechanism with the corrado panel?

sorry to hear that Matt. I replaced my soundproofing with some MLV and some open and closed cell foam. Of course the open cell foam got soaked, but thankfully its dried out. My car is pointing nose up, hence running down to the back of the car. |I've just shoved in loads of newspaper on the side screen edge and along the inner sill but water, being the insidious thing that it is, will certainly find a way in somehow. In the interim, is there any kind of sealant i could use on the outside in the slot where the outer trim fits in? I'll be putting some self adhesive rubber around the window in the meantime until i can book the bodyshop Edit: just seen that the photos dont show the water droplets on the trim at all, just the rain and inside misting, so there's nothing to refer to. They look clear on my phone though

Right, i definitely need a roof cover! Went out in the rain to have a look and its coming from around the top of the windscreen. Great 😡 I'll have to book to screen in to be replaced and resealed i suppose, but in the interim I'll probably pull off the old windscreen trim and replace with a stick-on seal, although not sure if that will stay on any any speed. Obviously it doesn't help if i have to drive in rain. Alternatively it could use some butyl rope on the inside and outside of the screen on top of the sealant. Not sure, but I'll need to think quick! The trim doesn't provide a seal its just an aesthetic, so i presume the actual sealant inside has somehow failed. Is there any way to remove the trim.piece at the front of the roof panel? It seems to originate about 5cm in from the corner, then track round, pool in a recess in the black seal and then drip into the car when the recess gets full. The pics might make more sense. Btw its rain on the outside as opposed to condensation on the inside, fortunately.. And condensation on the inside of the frame - so perhaps safe to assume that the sunroof is probably not the culprit..

good shout on the roof cover - ill definitely look into that! Any suggestions on the roof seal? Would this be any good: https://www.ebay.co.uk/itm/385038501623?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=ghqy_imatbi&sssrc=2047675&ssuid=62a0Nzj5QWe&widget_ver=artemis&media=COPY

Some pics from this morning. Paper at the front was wet and you can see where water has tracked round from the top. Some has again dripped onto the vent and speaker pod. But the door was totally dry around the edge so perhaps its leaking from somewhere else? Is there something to replace the sunroof 'seal' with? I know its not supposed to be a perfect seal hence the sunroof drains. If i had a proper garage i could remove the headlining completely as well as the sunroof and look at it throughly. See the moisture on the windscreen (although none around the moisture absorber!)

good point Shaun - i'll check the alignment of the door against the roof line and body

Great pointers Matt, many thanks. Should have taken some pics but i'll have a go tomorrow. Anyway, refitted the membrane and cleaned up the butyl seal. Swopped back the old sunroof panel keeping an eye on the clouds! The metal sunroof panel was wet on the inside although there was a small amount of water on the inner panel. Like you say it is pointing to an issue with the sunroof drainage. I've just wiped everything down again to see what happens tomorrow - its been raining again so hopefully should see something. Or ideally not! I'm also just wondering if today the water was just condensation on the body frame as it evaporated as i've removed the A pillar cover. Most of it had droplets from the middle of the top down towards the dash and a few drops sitting in the LHS dash vent. Only a very small puddle in the back today - about the size of a 50p piece.

Sorry, should have said the water drips were from the middle of the top edge of the inner door seal But i think you're right, its good as a preventative measure anyway, so at least that's eliminated

I took the pillar trim off and there was water dripping slightly from the inside of the seal, but just in the middle. The door membranes look intact. I did clear out the sunroof drains in the summer but recently fitted a new inner panel - maybe that's not seated properly? Its too rainy for me to try and remove and refit at the moment though!

Found a nice swimming pool in the back of my car, passenger side. Removed the soaked soundproofing and pillar trim and it looks to be coming from the middle of the inner door seal, then tracking round and running off the door sill. My car is on a slope so it all mainly collects at the back. Anyway, removed the door seal, pressed the profile a bit tighter and refitted pushing it all the way back. Had a cursory glance today and there's still a small amount collected at the back. Do you need to use any sealant or soft adhesive for refitting the seals? I'm conscious of not using something that will either attack the paint or that wont permit removal of the seal at a later date. I've also moved the striker pin inwards slightly to try and help the outer seal a bit more although this now puts more pressure on the lock when opening so I'm looking to move it back to the original position once the leak is sorted. Thanks Hasan

I upgraded from the standard 280s to 288s on mine (about 15 years ago tbh!) I do remember thinking that they were less prone to fading on hard driving and braking. A bit more sensible now so dont do as much of that tbh, but definitely a good improvement. I imagine some better calipers would be even better. From what i understood, the difference between the 288s and 312s was not so noticeable, although aesthetically they do fill the wheel better! Not sure if that comment was of any use or totally off topic.. Hasan

which connection would you say is the most likely - its a bit of a pain to get to the ones under the car tbh

Helps to use a bit of common sense first to establish a baseline! Ignition on, engine off, horn tries to sound but doesnt quite do it. Engine on horn operates perfectly. So all ok, although i thought that it would work with the engine off. It certainly did with the old scorpion alarm, perhaps its the Toad causing this? Battery was fully charged a few days back, and its quite new. 70Ah so enough capacity there. Thanks for the suggestions guys, i can imagine this wont be the end of it!

Ah yes, could be! Good call. Relay is clicking so I assume it should be ok? Good suggestion though, I'll check it again. Yesterday it tried to horn slightly as though the horn was seized. The wiring from the connectors - where is this routed? Thanks

Well here we go again. Changed the horns because i thought they weren't working. Tested the new horns with 12v directly- work fine. Pressing the horn and the relay clicks nicely, but no sound from the horn. Im assuming that there's no power going to the horn although i cleaned the connectors properly. Whats the wiring route from the relay to the horn and whereabouts is the earth? Can't see what else it could be tbh..

thanks, yes that would be great. As i dont have any covered area i think i'll need to wait until summer then if its a dash out job. Do you remember if you took everything out? Based upon Goldfinger above, its probably better to do it that way and i may as well do the heater matrix then too as a preventative measure. I had the centre and underdash trims off last summer for derattling, i should have looked at it then! At the moment, my dash vents blow warm air when the diverter is set to the screen, so presumably this is to do with the foam on the flaps? Watched a really good video from Humblemechanic where he replaced the felt and really cleaned up the airbox - but this was with the airbox removed. I suppose thats one way to do it too, but it would be good if i had a spare airbox to revamp and get ready and then just swop it in. I say 'just', corrado jobs are never that easy.. Funnily enough i've got a climatronic box in the garage that i've meant to graft into my aircon, but who knows when that will happen and i dont think the diavia modified airboxes are too common

8 years old, not bad! I'm looking to renew the foam on the diverter flaps - is it possible to get access to them without removing the dash and blower setup? Ideally i was looking to remove just the centre console. I believe someone did this not so long ago - if there are any pics available that would be great too. Nice little project over the holidays thanks Hasan

nothing like fitting nicely and properly finished parts to the car!

get rid of the Opel Manta front end and it could look quite decent

2007 until 2016 it looks like it wasnt MOT'd and thereafter it failed on a corroded brake pipe and windscreen damage. Definitely one to look at with caution - unfortunately a lot of people look at low mileage as the key factor, a point well known by traders...

Perhaps a dumb question, but if you fit 2 way speakers in the doors, is it then better to disconnect the dash tweeters? Its actually for my yaris where I've replaced the original 20 year old speakers with some (fairly basic) pioneers (ts g1720f). The pioneers sound tinny though so I'm wondering if having the original tweeters still there is the issue? Ive done some panel damping too, might stick some foam behind the speaker too. Fitted the same ones elsewhere and they didn't actually sound too bad, so not sure what's going on here. Polarity is correct too. Thanks Hasan
