    w123 auto box adjustment

    I have a 240td with autobox (1981). It has only 80k miles from new. WHen the car changes gear from say, 2nd to 3rd, it overrevs a bit before the next gear is selected. I am told there are two adjustments - one determines WHEN the gears cganfe and the other determines HOW quickly or smoothly it...

    Bleeding SLS on w123 estate

    I have rear SLS. I have just changed the spheres and fluid. I had heard the SLS is self bleeding and if so, how long does it take? I ran the engine for about a minute and bounced up and down in the rear but it is still low at the back. If it isn't self bleeding, how do you do it? thanks

    240td suspension spheres

    I am going to change the rear suspension spheres on the self-levveling suspension. Does anyone know the best place to buy these in the UK? I assume I drain the fluid or at least take off pressure, unbolt the old ones, bolt in the new ones, replace the fluid and bingo! Is it any more complicated...

    c180 oil level...

    You aren't going to believe the stupidity of this question.. I have a 2011 c180 diesel. I want to check the oil level. There is a red handled dipstick near the bulkhead in the engine bay but I cannot remove it. I also don't see any menu item which has an oil sensor level. Am I stupid or about to...

    240d compression

    I have a 240d from 1982. 120k kms from new. It is low on power and my garage tells me the compression is low on three cylinders. Seems odd since I had a test 4000kms ago and it was ok. So, it could be, I guess, head gasket, valves or rings. First, am I right and second, what is the most likely...

    w123 water leaks

    I seem to have the classic problem on the w123 estate that when it rains I end up with water in the rear foot wells. I need to remove the two plastic air vent covers on the bonnet/firewall to start with. They are attached with small square pegs that seem to push through. If I do this are they...

    Apologies if this has been asked a million times but how do you check the timing chain stretch on this engine? If it needs changing, is it relatively easy to do using a chain and a split link? thanks

    Injexion 5

    Anybody ever used this for cleaning injectors? It is meant to go into the fuel tank but I am told these things can be used directly by filling up the fuel filter with it instead. Anybody done this? (and done it with this specific product or are all the products doing this basically the same?)...

    240d engine noise and injection pump

    My 240d engine has done 100k kms in 30 years. The engine seems to be pretty noisy to me. I have done the valve clearances but nothing else. Injectors? Can the injectors be cleaned or only changed? All the filters are done btw. Also, there is a tinkling sound coming from the front of the engine -...

    180cdi 200cdi 0r 220 cdi

    I am told the C-class engines above are all the same but with different power outputs. Is this true? If so, how is the power output changed from one engine to the next and of course, can you 'upgrade' with some magic chip? :-)

    Diesel injection pump oil leak

    There is a leak of oil from the joint between the injection pump and the engine on my w123 diesel. I assume this is the gasket that needs replacement. Do I have to remove the pump and put a new gasket in or can it be eased out a bit and the joint redone with jointing compound? If I have to...

    240td auto box won't change up

    240td - 120k kms from new and never a problem. Suddenly it won't change up to top gear as it used to. The fluid level is correct and the fluid is in good condition. Any clues? I have not taken it for a long drive to see if it is heat related since I didn't want to get too far from home.

    w123 diesel running on three?

    My 240td ran perfectly until yesterday. I went out and it stalled after a few miles. Before it stalled it stuttered and hesitated like it was short of fuel and then ran on three and then stopped. I checked the fuel level and now if I try to start it will go after about 1 minute solid cranking...

    w123 rear calipers

    I need new rear calipers on my 1981 240td. The original parts are Mercedes but for new ones, I have a choice of Bendix, ATE, Girling etc and no-one can tell me which are the right ones to order. The piston diameter is 38mm. Can I fit any calipers with this piston diameter? My chassis number is...

    190e hesitates and misfires

    1989 190e. Runs well but recently after it has run a bit and then stopped it misfires and hesitates when restarted. Apart from the usual -distributor cap, dirty leads etc are there any other known problems this could be which are specific to the 190e? thanks

    190e won't start - odd

    190e 1989. I have not used it for about a month and it has been in the garage all the time and now won't start. The battery is fine and turns it well. There are sparks at the plugs and the tank is full. There are no blown fuses. The first time I tried to start it it did fire for about two...

    Checking 190E viscous coupling

    My 190E gets a bit hot (idling in traffic even when freezing it touches 105c on the gauge). I changed the thermostat and when moving the temperature is always at 85c or so. So, for the viscous coupling for the engine fan - how can I check it or oil (?) it to make sure it works?

    How easy is it to remove/inspect/change the rear springs on a w123 estate (with self levelling)? I have a knock from the rear and I need to look at the springs since sometimes they break right at the top. How long to do it? Any hints? Simple or not? thanks stuart I also posted this in the...

    Hello, I have a w123 (240td) 1982 - only 120kms though. Ever since taking it to have th injection pump adjusted a few years ago, I have leak of oil between the pump and the engine. I tried tightening a bit but it doesn't help. Is there a gasket between these two parts? I looked...
