The cruise control servo has stopped working. The fuel pump had to be replaced around 500,000 miles. Other than that it has only been routine things, like spark plugs, injectors, etc.
The car is on the slow side, but will go forever. extremely reliable, I have never had a single break down - keep in mind this car has nearly 3/4 of a million miles on it. It still runs like it is a new car and I recently had a Mercedes Tech go through the car from bumper to bumper including the engine to see what needed to be done. He told me that if he had not known he would have guessed the car had around 30,000 miles on it. The only thing I strongly encourage is do the maintenance like the service book recommends!!! I have commissioned a full off frame restoration for it this summer. Interior, exterior, and mechanical to turn it into a show car - I feel it has earned it. I guess in the past twenty years this car has become my baby.
P.S. Its replacement as my daily driver was a new Mercedes S-class.
WOW! 723,000 miles with no major work.
Wow! I just bought a 1983 240D W123 and I am looking forward too many years of reliable service. The only question I have is that he mentioned spark plugs. Did he mean glow plugs? As diesels have no ignition system, if someone is charging him for spark plugs, he should ask for a refund.
Diesels don't have spark plugs. I hope you're not getting billed for replacing something you don't have.
I have a 1978 240 D, it's an amazing car. "Colorado Beige" in color (I repainted it to match) The odometer is currently broken, however mileage is about 220,000, roughly speaking. If you hear sputtering near exhaust manifold, before you take it in to a shop, attempt tightening the six manifold bolts yourself. The bolts were loose on my manifold and after tightening them the car seems to have taken on a new life. A recent concern has deleoped because of "clunk" when the car is put into gear. Could it be U-joints or the problem discussed in another note wherein the dry-rotted boot has led to problem with the wheel assembly? My car was a Florida car, now an Ohio car... bad for rust.
I own an '83 240D, I absolutely love the car. I bought it from my best friend four years ago. It was his mother's car, and she kept it in immaculate condition. With over 210,000 miles, it is still going strong. I almost thought about selling it; but, the black exterior and black interior beauty is too reliable and lovely to depart with (although it only has 67hp). Viva Mercedes Diesels!
You'll be lucky if you get the same kind of service out of your new Merc. Built by accountants.
If your W123 has no door rust, spray wd40 into the drain holes. It will protect them from rust. Gut gut!
