Hi thanks skyisblue, I did think about trying to get another tcm but decided it was too risky. When i had first contact with ecutesting they said, "if it is un repairable we might be able to supply another one" I guess it would have been one they obtained themselves and repaired. Maybe you...

The problem with TCM had not occured before. "Transmission fault" and limp mode started at 97,000 miles and within a few weeks the car was too unpredictable to drive. For example if it happened when joining a motorway. I am glad to say that MB took the valve body which carries the ECU, out of...

My 2010 180 cdi has the Transmission Fault Go To workshop, OBD codes 793,722 and 720. My intension is to use ECU testing to rebuild the ECU. Having disconnected electrical connector, drained oil removed bottom cover, filter and removed the 12 screws securing the valve body plate I cannot get...

Afternoon All, I have a 2010 180 cdi with the Transmission Fault and obd codes 793,722 and 720, the plan is to use ECU testing to rebuild the ECU. Having disconnected the electrical connector on the box and removed the 12 screws securing the valve body plate ( and managed the oil removal) i...

hi Wong i have a A180cdi cvt, at 25k it played up, ratio got stuck joining the motorway I slowed down and increased speed again and it cleared. MB had it or a week and I think they just drove ir hard. I got them to change the transmission oil at the time, they did not want to do it. No...

my A180dci started playing up at 31k. eventually after pleading with the dealer they agreed to change the gearbox oil and charged me £207. That cured it. so if you want to sleep at night I advise get merc to change the oil every 30k. Mine has doen 57 now and still behaving but it will get a...

I was concerned about the CVT box, it was noisy a bit of a hum, and occasionally refused to change ratio. After complaining to Mercedes they eventually changed the gearbox oil early at 30,000 miles, now it has quietened down and behave impeccably. my wife loves it. I shall be changing the oil...

our 2010 car is too low for speed bumps which it hits regularly, it is an avantgarde with sports pack, not our choice but a good car otherwise. Is there any way the body can be raised? Do all springs and shocks have to be changed? the main problem is he low front end. Are the old mac strut...

I had the same noise and changed the injectors it did not fix it, I am sure air being sucked into the fuel system is contributory because the injection timing will move, delayed pressure rise with air in the lines to the injectors. Changing the seals in the pump discharge valves helped mine...

I had same problem and after doing all o rings on pipes it persisted. The last job is to change the seals on the delivery oulet valves to the injectors on the fuel pump. It now starts instantly and has done since I did the job a year ago. It is very fiddly and you need special spanner for...

hi axelvic. I used copper because getting them through to the self leveling valve and lining up the threads would have been nigh on impossible using any other material suitable for the conditions. They have been on the car for 3 years and no sign of any problems. I joined them back onto the...

Can anybody tell me how to reach the post of John Macintyre on b class cvt . I have been directed by e-mail to this link http://www.mbclub.co.uk/forums/engine/113116-b-class-cvt-transmission-failure-new-post.html . I did get to the correct thread initially but now I am directed to this one. I...

jetboy thanks, I have refitted them after cleaning the faces more thoroughly and it is a lot better.

I have fitted non oem front pads that do not have a chamfer on leading and trailing edges like the oem ones. Is this the cause of my slight judder please? I have already remounted the new discs with great care.

I have been in London in summer heat in traffic with no viscous fan, the electric fans come on at around 103 deg C but only for a few seconds probably once a year. Mine is ready to go back in service. A great advantage is better access at the front of the engine and it really is so much...

Dear all my viscous coupling has been under my workbench for three years now. Without the fan the engine is quieter and no doubt uses less fuel. However I do rely on the electric fans but they have only been on three times and the coolant temperature rarely exceeds 100C. Frankly in my...

Hello arjafffer and all , The claim news is quite excellent, better update you on mine. The car behaved itself for two weeks after software update then same judder happened again. Back to Mercedes this time a another dealer Newbury the one we bought the car from. They had it for a for...
