W126, BENZ AID - COMMON QUESTIONS AND ANSWERS

Thanks and a suggestion

First off, i would like to offer my thanks and appreciation for your oasis in the desert of dealerships. You folks make the old adage," the only stupid question is the one you don't ask" a reality. You have to love these cars to do what we do and your commitment shines! Now...suggestion..the special tool that you offer for the removal of the 103 water pump is a godsend. you might however offer the tool with this stipulation...PAY ME WHAT IT IS WORTH AFTER YOU USE IT..you might be amazed at the return on that concept!!! Thanks again and continued success. Dan

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)

Diesel Engine Specific Aid

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.
