counter

I'm just about to go out and see why the rev counter doesn't work on my 1992 300TE (M103 engine). I've also noticed that the air conditioning doesn't work and I think I found a thread saying they may both be related? (Although it probably just needs gassing) Should the air con make a "click"...

My 2000 CLK has developed a minor fault with the instruments, when switched on or off the rev counter needle vibrates (enough so you can hear it )for about 7 seconds. When switched on it does this at zero then it, the temp and fuel gauges all spring up and work normally until it's switched off...

Anyone know how to repair a rev counter which isn't working? Is there a common item which wears away and needs replacing?

on the 'after reset' trip menu does the total mileage reset back to zero after 1000 miles or does it just carry on. We go on holiday next week and i'd like to keep a record of the mileage we do so if it restarts i'll need to make a note elsewhere. Daz

Hi, Can anyone assist with the problem i'm experiencing with my new car? This is the 1st Merc i've ever owned and has took the shine off it. When you are driving on a Motorway, as the speed hits 70 mph at 2500 rpm, you notice what can only be described as a surging in the engine, as though...

I was trying to connect the power to one on my heated washer jets the other day and must have shorted it out because number 10 fuse blew. This protects the fan clutch, washer nozzles, rev counter, heated mirrors and the outside temp gauge. I replaced the fuse today which got everything...

I have changed my instrument cluster on my vito 108cdi 2000 model. The instrument cluster came from an automatic vito and mine is a manual and so the speedo, rev counter etc is severly out. I have been told that the cluster will need calibrating and that i may have to take it to a dealer. Any...
