560sel ignition coil

Have a 1990 560sel with 127k miles. Want to start changing the oil myself via the dipstick. Other sites say that it's best to disconnect the ignition coil before cranking the engine over after the change. This prevents too much strain on the timing chain. Have a repair CD but the coil is not behind the EZL as shown on the diagram. Looking for the location of the coil. Thanks.

Air Dam removal

I have a 79' 240D and have been doing the maintenance on the sun roof as per the Mercedessource kit. I have found that the air dam has a bit of rust on it and I wanted to remove it and clean/treat it with the anti-rust paint but I am unsure as to the best way to remove this. I am afraid of breaking it if I force it. Does anyone have any sequence of steps used to properly remove the air dam??? Thanks.

1984 300TD Fuel Guage Not Working

I just bought an 84 300TD (Yes, the wagon) and I really like it. One thing that I don't like is that the fuel guage is not working. It jumps all over at times, and at other times it will stay all the way empty (after I just filled it up) or all of the way full. Not sure if this is related, but when I fill it up, I have to put fuel in very very slowly (~.5 gal per minute) otherwise the filler fills with foam and shuts the station pump off.

1976 300D Wont change from A/C to heater

I am about to fix a 1976 300D that does not change over to heat when you turn the A/C off. We bought it from a dealer and know very little of the car's maintenance/repair history. I can tell that the car was well maintained and runs/drives great. The heater slide controls are working, but whatever is supposed to happen when you turn the A/C knob fully counter clockwise is not functioning. I was wondering if anybody knew of a common problem that I should look for when I repairing this.

1981 300 TD Wagon Transmission doesn't shift

While driving, the trany shifted to nuetral by itself. No position on the gear shift changes the condition. However, when I shift to park I do get a grinding noise before the gears mesh. Every other position is quiet. I was told that I may have to replace the transmission and I am willing to do so as long as a second opinion agrees with the first.

If I do need to replace the transmission, I need a good manual to help out.

1984 300SD - Transmission slippage

I had the rear end on jack stands and the front wheels on the ground while I was doing rear suspension work (shocks, springs, cv axles). I kept getting interrupted and left the car in that position for about 3 - 4 weeks before I finished and now the transmission feels like it's slipping. I've never had transmission problems and I changed the fluid and filter a few months ago. No fluid leaked while the car was jacked. Was it a bad idea to leave the car in that position for an extended period of time? I'm not sure how to troubleshoot this, any suggestions? Thanks.
