Hello

has anyone got any advice on how I might sort out my T4 dashboard clocks that have gone mental. Speedo, fuel and temp gauge all showing strange readings and they move about.

As mush as I'd love to say my 1.9TD is doing actually 110mph it is driving me nuts. I've had the clocks out and looked for any re-soldering that might need doing but no joy. I can't even seem to find a right replacement set on eBay or anywhere else. My set seem to be a little rare?

Part number is 53923262.
Any ideas?

Possibly not a rare model, just that they are ALL faulty now.
Part that is needed to fix them is no longer available (if it's the type I'm thinking of).
LOADS of threads/posts about it.

There must surely be a fix for this?
If there is sufficient need then I'd like to think that some enterprising person will come up with the part required.

If you can identify the part that is nla, and you know someone who can speak good German, I'd try a German T4 Forum such as

Dashboard - T4Forum.de

It seems there will be lots of us in the same boat eventually, so please keep us posted as to how you get on. Good luck...

IF it's the part I'm thinking of, it's an integrated circuit that is no longer manufactured, and unless you find someone with 10 year old stock, there is no substitute.

Look here (I used the Search function ):

Search results for query: Instrument panel fault

www.vwt4forum.co.uk

Plenty of reading.

Thanks for that link - interesting. The 'search' facility seems to work much better than it did before the Site upgrade!

Biffro - I assume that your speedo is electronic, ie not cable driven?

Thinking aloud, and wishful thinking at that - would it not be possible, at least theoretically, to replace the Integrated Circuit with a remotely wired Printed Circuit Board? Anyway back to the present.

I look forward to hearing how you get on finding a replacement panel.

Thanks lads.

Bloody hell, there's loads of us! At least I'm not alone . Looks like up stuck with Ebay tracking. Might have a crack at a German site but would have to some how convert the dial to MPH.

At the moment I'm using my iPhone with an app for a speedo.

AFAIK, once you get an "electronics board" that works, you can swap the speedo dial....after-all, it's only a metal plate with numbers on it!

@Jim24,
"Thinking aloud, and wishful thinking at that - would it not be possible, at least theoretically, to replace the Integrated Circuit with a remotely wired Printed Circuit Board? "

Considering the original IC probably contained something like a 1000 components (300+ transistors), I think you may need a roof box to mount it on.....

Evening.

If you google Dash Cluster Repairs and you will find companies that repair these. Give them a call with your part number and they will tell you if it's a model they can repair. A mechanic friend took mine out and has sent them to a company in Southampton for repair.
The other alternative is to give James at Cali Campers in New Milton, Hampshire a call 07770827527 he may have one as he has a warehouse full of T4 parts

I hope this may help

 

[Biffro]

Thanks Welchy, that's a good shout. I've tried Cali Campers but they said they haven't had one of these in for months.

Hi Biffro.

Hope you manage to get it sorted.

Cheers

Hullo

I had a similar problem on my T4 2.5tdi some years ago, which surfaced a few days after a service. The clocks would not always zero on switch-off, and/or would behave erratically and read silly things like 130mph or 6000rpm (at a real 40mph). Problem is it affected the vehicle running (feedback issues?).
Anyway I spent a year trying to track down the fault but in the end had to ask a T4 specific garage. Apparently these issues MAY arise if the battery is accidentally disconnected while the engine is running - this seems to upset the ECU and/or speedometer circuitry. In my case the speedo was at fault and I was able to get a 2nd hand unit (in KPH, but as I live in Spain what the hell). It cost me an extra 30 quid to have it re-clocked to the equivalent of miles on the odometer. The MOT/ITV here haven't noticed so no problems with the mph-kph switch).
Now I'm not saying this is your problem, but I know that at the time of the service we were using a 'convenient' battery disconnect fitting on the battery because it's a motorhome. These things are a pain in the bum and I suspect the garage mechanic simply failed to reconnect this properly due to not realising he could simply have unscrewed it to isolate the battery.
Bottom line is this may require an Ebay speedo unit, but if you do, then try and get them to re-clock it as part of the deal. I also believe it's possible to send yours off to have it checked by independant speedometer specialists. At least you would eliminate this as the problem source.
I don't suggest you use the opportunity to reduce your mileage however . . . .
Good luck.
