These are great cars, and they have one of the best diesels MB ever produced. In addition to all the same issues that affect similar era 124s, I'd say that the relatively weak 722.4 transmission is an area of concern, as well as the by now aging engine management vacuum devices that control the EGR and turbo boost functions.
Of particular concern would be the vacuum pump, which if not addressed can eventually implode, sending tiny bits into the engine and potentially taking out the timing chain. An upgraded pump is available, and is less likely to suffer this catastrophe.
The E300D was made in 1995 only. The other 124 diesels were 300D in 1987 and from 1990-1993.
The weaknesses of the actual 95 E300D are biodegradable engine wiring harness, likely A/C evaporator leaks leading to replacement, highly likely glowplug seizure into head, and possible headgasket replacement. Otherwise, great car with high 20's mpg town and mid 30's mpg highway.
1995-1997 to be precise and that would make them W210 body.
The non-turbo 3l diesel engine has some glitches with actuators and is considered underpowered, but let's establish what exactly we are talking about?
Posts #3 and #5 still have you mostly covered, even if it's a '95 MY. That's rather a high amount of mileage, but these cars, and in particular that engine can last for many more. Hopefully the price reflects the mileage
Those engines were mounted for 1 year on W124 and for 2 years on W210 models. There is wealth of information about them in W210 section. Common problem at 10 years mark are deteriorating fuel lines, what is not a big deal to repair. Besides the engine surging I have not hear about any problems with them. If there is issue with vacuum pump on them, that would be the only time I hear it.
Than in lack of diesel section, we are advised to post diesel topics in General section.
That's so I can find them online, if I manage to get thru with online purchases, that is. Still can't find credible stores to ship to Saudi Arabia. Hopefully I find them in English so I can distinguish my face from my *** looking around.

It's an age since I last worked on a 722.4 box changing the fluid. Does anyone have a link to the current MB spec sheets please?
The 7222.6 has an excellent 'DIY section' although I can't seem to find similar for the older unit, apols if I have overlooked it.

My E320 1995 has went through a recent tune up and I have fixed a couple of CELs. I have changed the bio-junk upper wiring harness and throttle body. New air filter, spark plugs, spark wires and coils. New 02 sensor. Cleaned MAF sensor. Transmission fluid and filter change and that's about it...
My ASD light has been permanaently on for some time. I am not experiencing any problems. New legislation in UK means that I will fail my MOT test and have to take my car off road. Anything to do with the brakes is a serious failure in UK and I am not allowed to drive it, even home from the...
I have the w124 with the famous BEEEEEEEEEEEEEEP chime noise. Sounds like an oversized mosquito. I really want a new one, like the new 2018 G M chime sounds awesome. This one imo sounds like a great chime:
Or something like it. I just want to know the easiest way to replace the buzzer to any...
