W116, BENZ AID - COMMON QUESTIONS AND ANSWERS

82 300D has slight miss on one cylinder

82 300D has slight miss. This engine has 157,000 miles on it and runs good at highway speed. I can losen the fitting on each injector and make it run like a gas engine when you pull a plug wire. Has only slight miss when all injectors are tight. There is definitly a lose in power at low speed taking off from a light etc. The injectors have been pop tested and all are good. Compression test shows around 325 to 350 psi on all cylinders. I have adjusted the valves twice to make sure one was not to tight.

Multi accessory electrical short

i have a frustrating situation with my 89 300sel. my #15 fuse is blown, and it will immediately blow if replaced. My seat belt warning light constantly flashes, cabin light will not come on when doors are opened. they can be turned on manually, and my central locking system is inoperative. I realize that I most likely have a positve short to ground. Any ideas about a good place to start looking? Do these three symptoms point to anything specific? Any and all assistance would be appreciated. Thanks Dan Hammond

88 190D diesel engine wont stop!!

I have a 1988 190d 2.5 liter NA. I started the car like normal except that the brake pedal was very stiff as though the power brakes had stopped working. Also when i went to turn off the car it kept running so i hit the manual stop on the fuel pump. So the problems are simultaneous. I heard that it is a possible bad vacuum but im not sure please help. thank you.

Is Bosch style alternator compatible with Bosch Valeo style alternator

I have just pulled off my alternator for replacement and have found it to be a Valeo style. When looking for a replacement, I have found that Bosch makes a "Valeo" style and a "Bosch" style. Are these alternators interchangeable given the same plug for the wiring harness? Thanks, Justin 92 300D 135k (daily driver) 85 300D 305k (wife's car)

Okay, so I bought a 1983 300D Turbodiesel. And now:

Hi all. New member as of today, and today I also picked up my 2nd Benz. I have some experience with my 1971 280S, but today, I bought my first diesel. The cars rather amazing overall, for a black on black leather car with original paint. One owner. 200K miles. A few little problems that I already see answers and/or parts for. Here's my concern. The car is amazingly slow from a stop to 10 or 20 MPH. Then it's decent, much like a gas car. I see an unusual "part", seemingly disconnected in the engine compartment. It's like a little frame with heavy coils inside of it. What is that part??? It seems to perform much better once it's warmed. I know NOTHING of it's history aside from a clean VIN check, one owner, 400 miles in the last 2 years and it was probably garaged.

84 300TD Wagon won't start parked on a hill

My '84 300TD Wagon won't start if parked facing uphill - even the SMALLEST of inclines actually. Doesn't seem to have a probably parked facing downhill. Because bleeding the injectors gets it to start, I'm assuming it's air "in the system". Is there something I can do about this or is it just because the car is old? Thanks.

87 300TDT IP shut off valve

My 87 300TDT has began to be hard to start after it has warmed up on a warm day here in FL. Has left my wife stranded 2 times. After it cools off overnight it starts right up and runs fine. I am thinking that it is the Injection pump shut off valve- The IP was replaced by Mercedes about 2 years back and they did not replace the shut off valve. Could some one describe what happens when this valve begins to be intermittent or fail? Many thanks, David
