Another D2 S8 gets some TLC

its good to see someone who does their own repairs to this extent

Thanks all, for your kind words and helpful information.

I've got the oil pressure switch on order, so hopefully that'll solve the recurring warning.

The electrical fault on the gearbox is probably the wiring to the selector switch itself, as I already identified a broken wire there, so perhaps some damage has occured as it has been moved around.

The CD changer has always been quite unreliable, so I really need to look at alternatives to try and get a iPhone interface. The Dension offerings look quite pricey unless I can luck out with a used one.
Any other suggestions?

Thanks again
Brian

The Dension Gateway Lite BT seems to have rocketed in price. A year ago I paid £105 + shipping.
Now it's £199

I know others have used something like this though which is half the price:

It looks like you've got a fog-light grille missing there.

I like these usb-nachruesten.de for simple bluetooth and hands-free addons, although last I checked they weren't shipping to the UK any more. Simple and reliable if you can get hold of one though - that's what I put in Paul's FE.

There are of course the OEM-lookalike Android units that Marcel and I have too. They have Carplay for a higher level of integration, but are obviously more complex to fit and not really plug & play.

Weird faults like that in the TCU are usually a symptom of water ingress. Alas the TCUs are becoming pretty unreliable these days and so they are quite rare and expensive. I'd swap it out for a known-good unit to see what happens before chasing wiring issues. I may have one I can lend you for diagnosis - I'll have a look.

Out came the interior – which I wanted to do at some stage, just not right now.


Once rather drowned yaw sensor. The acceleration sensor looked okay, but this had fried itself.

I wonder if there is a way the sensors could be mounted off of the floor, say 10mm, to alleviate the dangers of water ingress. One of MJ's magical designs for a support mounting that could be made waterproof as well?

I spent ages looking for a working alternative head unit, but none are 'stock' and trying to keep the car as original as possible - at the moment.

Yes the Nachruesten works great. connects automatically when in the car. Currently using my mobile for music, calls (hey google), and google maps / waze. Only drawback is that I need a mobile with at least a 10" screen!

Thanks Paul. I think we are a bit doomed with the sensors, as the rear seat air duct runs over the top of them. Then again, a smart 3D printed case or clamshell might work with some o-rings to seal it where it mounts to the bosses on the floor. Wiring might be a bit tricky to waterproof though.

Maybe I'll go a bit 1980's and find a way of bagging them up

I have seriously considered the viability of a multi-point moisture detection early-warning system, since protecting things against water ingress just allows the water to stay there and damage something else. Conductive pads on the floorpan, in the boot, electronics box, and a little above the base of the raintray would let you know something is amiss and needs investigation, before anything bad happens.

Thanks MJ - useful info indeed.

There are a couple scrap cars in the breakers that I might go and plunder, for the acceleration units. I think the Yaw sensor getting water ingress seems to have then fried the acceleration sensor, as it didn't look water damaged

I'll go and research the usb-nachruesten website. Maybe shipping to the UK is becoming more possible now that things have settled a little.
