1980 300SD Oil Consumption

Oil consumption has appeared as an issue following the Christmas holidays. During this 2 week period, I drove very little. Following the holidays, I found oil consumption to be high. Initially 1.5 qts in the first 150 miles! Next oil top-off showed consumption down to 1.0 qt in same distance. Currrently, oil consumption has recovered to the historic 1 qt. per 1500 miles. Rear of car has oil mist grunge so I suspect it was going out tailpipe. No new external oil leaks. I suspect valve seals or a turbo seal though turbo boost has remained unchanged (max P and boost response). Comments?

1993 MB 300TE Wagon 2WD, code reader for my car?

Dear Sir or Madam,

Is there a reliable hand held code reader for my 1993 300TE Wagon, that you would recommend/sell. My local shop charges $75 just to read the codes. I am also looking for a good shop manual for my wagon. This is my first Mercedes, and I am very impressed by the ride, but there is no way I can afford the upkeep without doing the work myself. In less than a month I have spent $750 in getting the air mass flow sensor changed ($590 for the part that was supposedly OEM, and that is why it cost so much, was actually a Bosch component) and $450 for a new vacuum shift delay relay. $150 of that $1200 total was for the diagnostic read.

'82 300TD - Circuit 1 fuse blowing

I have a 1982 300TDT. My fuse for circuit 1 keeps blowing. I have the correct color fuse installed as per the fuse box specification.

Over a year and a half ago this started happening. Up until now I could just replace the fuse and it would be fine for several months, so I just let it go.

Now, however, it blows immediately as soon as ignition switch or lights are turned on.

When this blows I lose my dash lights, right rear taillight and right marker light. It basically means I can't safely drive it at night until I get the problem taken care of. The turn signals still work, by the way, if that somehow helps to diagnose the problem.

123 Suspension Torque specifications ??

123 '83 300D turbodiesel:

I am rebuilding the front end on this car and need torque specifications to properly replace the nuts and bolts in the front end. I am installing new shocks upper a-arms, sway bar bushings etc. If you have the specs available please give me a call at 310-291-2035. My car is in the shop right now and the technician asked me if I had any of the specs.

Short notice I know and I appreciate any help you can offer.

Thanks,
Michael

1984 300D Cruise control issues

Hi all. Hope the New year is being good to everybody. I work this site for all I can and have read every question that pertains to my particular car and have gained so much knowledge. I am grateful to Mercedessource for providing this great data base. That said my question is, that if I set my CC at about 62 mph and around 3000 rpm it works fairly consistant. I say "fairly consistant" as eventually it gets a little jerky. If I don't set it right around those values it runs even more jerky. It surges and then backs off again and again as it tries to compensate for rises and dips in the highway. I have read about the amplifier under the dash and loose ball sockets in the linkages. Has anyone had similar symptons and addressed this specific quirk and what was your experience and outcome.
