Evening, my old ‘85 300TD OM603 flung up a bit of a problem this evening and wondered if the group could help. About 6 months back I renewed the rad, top and bottom hoses, water pump and thermostat. I have not renewed that small piece of rubber pipe running off the thermostat housing because I...

Evening, I’m after a few bits for my ’85 300TD if anyone can help please? Front and rear mudflaps - with logo Fuel sender unit (touring/estate version) Roof rack Ta! Dot

Morning, I'm bringing up what seems at first sight as a subjective issue of running temperature on a W123 diesel. Looking around the US forums there seems to be varying views on running anywhere from under 80 degrees to just over 100. I'm obviously still acquainting myself with my 300TD, with...

Evening all, in addition to the 123 I’ve recently got hold of a 1991 300TE. It’s been pretty well looked after, but I have taken it on with a couple of issues. I’ve decided to post here instead of the electrical section, forgive me if that‘s incorrect. M103 engine I think. When I fire her up...

Evening all, I’m currently still getting to know my ’85 300TD, and she’s beginning to run well. In doing this I want to begin cleaning components in the engine bay and the fuel pipe work to give a nicer appearance. The injector pipes covered with orange insulation tape which I began to remove...

Ahoy all, I’ve fitted a rather nice Blaupunkt MR21 Hamburg stereo into my W123, and I’m getting awful sound from the speakers, no real volume either. I’ve had a look at the speakers and they’re Blaupunkt too, but can anyone suggest any alternatives? I’ve also got two speakers in the rear at the...

Hi All, I’m making some progress with the ‘85 300TD, although still having some electrics issues I’ve put on another post in the appropriate section. My replacement rear passenger door actuator arrived today and was duly tested and fitted. Works a treat. I worked around the rest of the doors...

Evening all… Slowly making progress but have run into another problem. When I bought the car the previous chap had fiddled about with some of the earth wires under the dash. He could not remember why. I had about three exposed which meant I had no indicators working on the car. Electrics...

Morning All, does anyone here know of a supplier of window rubbers and channel for a 123 at all please? Also for the sunroof? I’ve seen the guy Kent in the US does them all but won’t ship to UK. Most of mine are pretty good but I’ve got the drivers door channel falling out. Thanks all Dot

Morning All, So I’m getting on with trying to sort out the ‘85 300TD. It will not turn over. Ignition on, glow plugs actuate, nothing else aside from the click when you turn the key to position 2. He told me that he’d also been trying to remove and aftermarket car alarm (80s style) and had...

Hello, I’ve recently delved back into classic Mercedes ownership in the form of a 1985 W123 300TD auto in classic white with 157k on. Structurally excellent, but currently not running due to problems extracting an aftermarket 80s alarm system which the previous owner lost the will with. So...

Evening All, I’m working on my 92 300 TD and am a bit stuck. All running fine and no history of electrical issues. Done my insurance so my son can drive it, but have had to have a black box fitted. Fitter arrived and had trouble finding a spot so was talking to his mates on the phone for...

Afternoon all, I'm after some help please. The old '92 W124 300TD decided to not start the other day; issue - no glow plug lamp on the dashboard. No bother, she's an old girl so with a little Easy Start, I was able to get home. Running like a dream. So I did some online investigation as I've...

Dear All, I'm re-commissioning my old 92 W124 300TD with the OM603 fitted and want to do a few jobs to get me started. I've been trawling the net all morning with little success so I'm turning to the forum for help. I want to change the fluids as part of this. Can anyone recommend the best...

Morning, I'm in the midst of resurrecting the old 300TD, 1992, 260k, auto... and I seen to have lost the vacuum system. I've repaired one of these on a W123 in the past, but I just wondered if there are any pointers or a diagram available so I can nail the problem please? I've got the tools and...

Hello All, My son wants to use my old estate while his own car goes in for a winter's welding and restoration, so he's asked if he can use the tank for while (the boy has taste). The thing is it hasn't been on the road for 4-5 years, and needs a few servicing bits (which I can do) doing as well...
