Guys,

New MB diesel owner and new to the boards. Didnt think my first post would be about a problem..Hahaha Have had my 240D, 181K miles, mint, one owner car, for a month now, ran flawless up until this morning. I started to notice hard starting in the cold morning a few days ago, Figured the glow plugs or relay needed to be changed since this car sat for 6 months(but warmed up every week) till i got it. So this morning, it wouldnt start. Kept cranking it, nothing. Since i was free today, decided to take the plugs out and inspect, all but one had oil/diesel gunk on them.

My understanding is if your GP isnt getting hot, then the gunk doesnt burn, hence the stuff on the plugs. Tested the plugs with jumper cables and the ones that were covered in oil were not lighting at the tips. Had extra plugs, tested them, worked, popped them in the car..Now, starter wont turn because i drained the battery from cranking it excessively..so i thought.

Hooked up car to another via jumper cables, let it charge for 10 mins or so..Lights all strong, accesories, etc. Turn the key, key wouldnt turn for a second, seemed jammed, turned it to 0 position, couldnt pull it out, jiggled the wheel a lil. Key turns, glow plug light works as it supposed to, but now the starter wont crank, and all i get is a click..

I ran out of daylight so i didnt get to try jumping the starter or tapping the solenoid..

What do u guys think? something with the starter or something with my ignition switch? Its just coincidental that the key jammed, wouldnt turn, and now the starter wont crank.

BTW, I love this car. having owned various Hondas, e36, e46 BMW's, I find that its such a handsome and nice driving car abeit slow, and I appreciate this 80's MB technology..They DID build these better back then.





TIA

-Ray

Could be a defective key switch, but more commonly the shifter bushings fail and you may not actually be in park or neutral as it indicates. If that is the case it needs to be addressed asap. But in the meantime, with one foot on the brake firmly, turn the key to the start position and start moving the shifter around. If it turns over, then you have found your problem.

MB was nice enough to provide you with another way to start the engine if you need to move the car or whatever. Turn the key to the run position, then go out under the hood. On the passenger side inner fender is a black plastic cover over a few cables. Remove the cover and you'll notice some screws.. The smaller wire is the starter solenoid, the larger wire is a battery cable. Short them together with a pair of screw drivers or needle nose pliers and the engine will crank. This bypasses the key switch and the neutral safety switch.

Boss, tried to short the starter, it barely wants to spin. When i hit it with a hammer while I short the wires, it tries to spin a little faster but not enough to crank the motor over...Looks like the starter is done. The orig owner of this car was my uncle and when i asked him if hes ever replaced it, he said no..Looks like the 29 year old starter finally took a dirt nap.

Ray, kamusta? :)

First of all I know your battery is new. Are you sure this is the correct battery? I didn't check your battery out that well since I assumed it was the right size. Should be a group 49 or better. The specs are on the battery. If the battery doesn't have enough juice it will spin the starter slowly. Are the exterior lights dim compared to before?

IIRC a failed starter does not want to spin (solenoid clicks but nothing happens). I could be wrong. How many times did you attempt to start the car? You could have drained the battery. This, plus the ignition switch issue could lead to a harder diagnosis.

If it is the starter, you're lucky because the 240D has lots of space around the starter and it's easier to replace than, say, my 300D or even a non turbo 300D.

Dood, yeah it was the starter..once i pulled it, hooked it up to the battery to test and it wouldnt even spin...Orig 29 year old starter. Amazing. Once i got the new one put it in, and a new set of GP's, it fires up with one click in the cold morning. Ur right, it aint hard to replace. =)

I hope you used Bosch or Beru glow plugs only. Did you also ream the holes of carbon build up?

People say only Bosch rebuilt Starter hold up well.

Be sure to hang on to your Paper Work so you can benefit from the lifetime warranty (if there is one).

By the way Ray, if you need a glow plug reamer send 300Dman an email. He's local to us, or you can borrow mine - I also got it from him.

Bosch has good warranty on their parts, I recently got a Bosch battery for my 190E. Paperwork came with the battery. Same deal with the rebuilt alternator on my 300D.
