Pictures of the circuit board, both sides are at the bottom of page one by the way Mark, have a look see what you think. I'd like to try and get this fixed.

I've just had a look at mine and it's a VDO cluster!

It's probably been contaminated - by crumbs from that sandwich :D

Sorry , that's not helpful is it :shake: I've got to admire your tenacity though so good luck fixing it.

Second one first.
Large black gear in the middle as reference.
At 9 o'clock, there is a mark across a track. Is it dirt, or a scratch? If the latter, is there a break in the track? Easy enough to check, with a DVM, measure (zero ohms) between the two component pins at either end of the track.
Slightly up from that mark is a large solder connection, which may well be to the motor. It's hard to tell in the photo, but it's got a couple of qualities that might suggest a dry(cold) joint. If you have a soldering iron, I would reflow all this connections. It costs little more than some time and a bit of solder.

First one second
The motor is likely controlled by that IC in the top right corner of the component side pic. It would be a little more complicated rigging this circuit to run without some other bits of kit.

It occurs to me that disabling the odometer would be a great way of hiding the mileage on the car.

Thanks for that Mark

I'll take a closer look at that scratch and get an DVM on it! And then I think you are talking about the lump of solder just next to the scratch? (The lower left of the two similar ones close by the scratch?). I can take a closer pic. Macro the **** out of it! Lol

I have got a soldering iron but would be very under confident in using it. Would I just need to put a dab on the scratch, and then a further dab on the nearest 'lump', or does the lump just have to be livened up with a hot iron?

There is a breaker b4 1.9tdi in Aberdeen which I could go and take a look at I suppose.

And yeh, going through this process I've learnt how to clock an old car! Lol. Kind of why I want to get this one fixed, so as to show honesty down the line.

True enough, although with the MOT history check these days you'd have some explaining to do anyway.

Things have certainly come a long way though compared with the looks of these clocks.

For reflowing solder

Option one. A quick once over that I've been guilty of, also. Just reheat it, and let it cool as normal. However, if there's any contamination on the competent leg, this may be a temporary fix.

Option two. I usually wick off the old solder, apply flux, and fresh solder.

along with solder wick (copper braid which is used to remove old solder)

and flux.

If yours is VDO, you can probably use bits from the Ebay cluster.

You can use a multimeter to check the traces on all the tracks to the IC. You should have continuity to all pins

Well I tested all the tracks on the circuit board and all measured 0.00ohms. Everything does look ok...so had another look at cogs etc and I found this...the missing cog! On the end of my finger.. Same colour as the old small cog. It was jammed in amongst the other cogs....I just wonder if this was stopping something!!!!

Will put it back together and go for another drive! Fingers crossed, again!! Lol

Ha, well done. That definitely deserves a beer. :)

Hopefully finally done.

Good job for persevering

:)
