Also rattling!

Well, as you have read in my previous messages, my 190E 2.3 8v (1992) also makes a rattle. Next week I will take it to a Mercedes dealer to have it fixed. I hope they don't have to change the whole tensioner assembly, that will cost about 500 dollars! Hopefully changing only the belt and the shock absorber will cure the problem.
About the blown ECU fuse, does someone know if that's a common problem in 190E 2.3 also? Is it located in the same place? How do you gain access to that fuse? I am anxious to see if mine is blown too!

Best regards.

Hellme, I hope you get all your problems solved. When so, carry the car to the previous owner to see its face ;-)

Another interesting question

Thanks, Babybenz!
"Unfortunately", my fuse was OK. However, I found something very interesting: it is a kind of rotary adjustment with numbers near the ECU, very similar to the one that is in near the ignition ECU, in the opposite side of the hood. What is this new adjustment? I have heard about an adjustment of the ignition timing, but that should be near the ignition ECU, so I assume it was the other. Can it be something related to the enrichment of the mixture as it is near the fuel injection ECU?
Babybenz, if you have the service CD, could you please check this? I would be very pleased to be able to change it (I have heard that the previous owner had "something" changed to gain in economy at the expense of performance, perhaps is this!)

Thanks, babybenz, but now I am totally lost:

Thanks, babybenz, but now I am totally lost:
My car has one rotary switch at the front, near the ignition ECU, with 2 positions: S and N, currently set to "S".
Behind the battery, near the fuel injection ECU, there is another one with positions from 1 to 7, currently set to "1".
Does someone know what is this mess?

BTW, I use regular 95 octane fuel.

Best regards
