W124 OVP number

[balge]

Can anyone confirm part number for OVP relay K1/2 ('92 300TD)

I have p/n A2015403745

Also are there any variations e.g. are petrol/Diesel ones different Are the single fuse obsolete/old stock replaced by twin fuse type? Or are they interchangeable?

You can use the twin fuse one in place of the single fuse. I have done just that in my 126. That'a the same part number I have on my old spare OVP's and it seems to span all the models, petrol or diesel.

Good oh.

Just that I saw this

Überspannungsrelais ABS für W124 W201 W202 | 2015403745 | 2015403045 | 2015403245 | 2015403845 | Mercedes Ersatzteile

where it said
"für alle 124er außer bei Fahrgestellnummer
(124.008/ .022/ .028/ .029/ .034/ .036/ .042/ .052/ .062/ .066/ .082/ .092)"

which google says means 'all 124 except - the chassis numbers seem to be coupes and limos mainly, maybe they have different alternators or something?

Been having an odd niggle,OVP light staying on, tacho not working - but only every third or fourth start, and then everything clearing up within a minute or so.

Tried swapping a few things around and did a few basic electrical tests, alternator output is fine, rest Voltage ok, OVP fuse functioning - ie slow running gets rougher when the fuse is pulled and cleans up when fuse goes back in...

Noticed it had a different OVP when I swapped a spare in, had a single fuse one (a2015403245) in before...no change.

Think it might be the battery as the readings are all in range, but only just so probably worth a change next week anyway

Just wondered if anyone had seen similar?
