Hey guys, I've got gauge cluster issues which are multi-layered and didn't bring up any concrete answers in search.
I recently took ownership of my 325e Baur and knew at purchase that the Odometer didn't work - an easily fixable issue with replacement gears, sure. I thought - 'I'll get to it soon.'
Then, on its last drive, the gauge cluster failed - all gauges dropped to zero save for the speedometer which kept working. OK - a little searching dug up the SI batteries as most likely culprit.
At least I now had the necessity to pull out the cluster and deal with both issues at once. Now here's where it gets tricky:
I've pulled the cluster and, if you look at the pics, my VDO cluster (logo on face, stamped on back) has a Motomoter speedometer unit in it. And the later-series Motometer Lithium battery SI Board. That doesn't seem right?
Further to this, yes the odometer gears in it are toast, but also there seems to be some heat damage on the Motometer speedometer PCB (pics attached). I'm wondering whether this may have been the cause of the cluster failing, and not the batteries?
Is this sort of PCB component damage repairable, or should I begin searching for a whole new unit?
Is my gauge cluster likely a Frankenstein assembly done by a previous owner - and when replacing components should I be looking to replace like-for-like with what's in there?
