Top 20 1998 Mercedes-Benz SL-Class Questions & Answers

I have a 300SL and I encountered a similar problem. My dash lights were not coming on, the car was not starting and there was a ticking noise coming from the passenger side(near airbag) when I was trying to start the engine. I noticed that my ignition switch was slightly getting loose. There is an adjustable cover around the ignition key ( like one inch wide) that can be easily tighten by hand. The purpose of this cover is to hold the ignition in the proper place for the electrical contact. It also has a few marks on it which show you if it is properly aligned. By adjusting it to the proper spot, I was able to fix the problem and the car starts just fine right now. Sometime (once in 6 months) it gets loose again and I have to re-tighten it, but it only takes 5 seconds to do so. It seems like the ignition switch is very sensitive on these cars and the smallest misalignment of the switch can make the car not start. I hope this helps.

its in the trunk

Hi Your S class has two batteries. The smaller one is located in the engine bay, and the bigger one in the boot (trunk). No need to access any of them, simply open the door with key, insert key to start engine, you will notice that not all ignition lights will come on, but the engine WILL start, and the batteries will be recharged after a short while.

did you look in the trunk?

There is a good set of instructions at www.benzworld.org Do a search for outside mirror replacement and i think you'll find all you need to get this accomplished.

you will have to remove the seats in the back or go through the trunk on 2 seaters to access the motor to disconnect it. if you try to force it manually you will more than likely cause more damage............please rate

you should have a fabric panel behind the front seats.if you can not gain access to the motor from the trunk.
