300D dash lights fail after radio install

My old Becker radio in the 300d gave up, so I replaced it with something new. Everything seems fine except now it seems I have lost dash lights? Any advice would be appreciated.

Was having hard starts in the cold last week, the glow plug light went out. Ordered the clean=out tool and 5 new glow plugs. Job went smoothly with your instructions. Starts great again, Thanks!

Salvaged Spares

Hi, all; newbie here.

I'm not sure if I've selected the correct chassis number because MB use different classifications of their models over here in Europe; however, I should imagine that the principles would be the same, regardless of location... at least I hope so.

The problem I have is that my beloved Benz (E240 Elegance Tiptronic - 2597cc; registered November 2000) requires a new ignition switch. Enquiries made to dealerships have all quoted me a price of roughly $800 for a new switch and 'Green Key' (apparently needed to programme the new switch into the car's computer).

Here's the $64,000 question: can I use a salvaged switch (cost $40) and programme that into my car using a 'Green Key'?

Please... someone give me the answer I'm hoping for!

617 Turbo diesel Low Power at low RPM

I have a 1982 W123 with about 240,000 miles. It runs great at normal highway speeds.
The problem(s) are first at low RPM it takes a lot to get the car going, it can be floored and barely start to move. The other day my wife parked on a hill and when leaving it took a long time for her to move. (transmission is good, just replaced) Power is excellent when rev's are up, it will actually chirp the tires when shifting gears.

Fixing Leaks (oil and coolant)1981 300cd

My 1981 300CD has some leaking issues. I have traced the coolant leak to the fact that the radiator has bulged along the upper edge and is leaking fluid under pressure from the joint between the tank and radiator.
Are these repairable? What else uses the same radiator or one close enough that I can cross reference to try to find a good used or inexpensive new rad?

1983 300D Just installed Optima 34R

A note on putting an Optima battery into a Mercedes. If you can dig up an Optima 34R instead of the standard 34, the posts will be in the correct position for the Mercedes cables. The battery comes with a couple of adapters. If you drill out the driver's side battery clamp stud and put a long bolt through the new hole, you can use the type 78 (looks like a 'C') adapter hold the battery in. You will need to add an insulator to the '+' cable as the OEM setup uses a cover on the battery.

380SL Hard Top problem

I am trying to replace the mechanism that holds the rear of the hard top in place on my 83 380. I loosened the nut to remove the shaft but there is a plastic piece that fits over the locking mechanism that will not allow me to remove the shaft. Does anyone know how to take it off (and replace it when reassembling) without destroying it?

Any help would be appreciated.

Thanks

heater fan fuse 1985 300 TD

I have and run for the last ten years a 1985 300TD wagon, about five years ago I replaced the heater fan motor. Now the fuse seems to be blowing frequently. Sometimes I can get it to last a few days, then only a half hour or so. I did notice in the fuse panel someone before me, conveniently painted a little red dot by the heater fan fuse. The fuse in there is a blue one and that's what I've been replacing it with.

Thanks,
Jonathan
