Hi all, M102 W124 230CE, losing coolant (about 3-4 pints per week!) I have looked when hot, when cold but can see no obvious leak, reasonably new radiator, thermostat plus housing and expansion tank cap. Also when I go to top up, invariably there is still pressure in the system. I did a...

Ok, My MB Stealer has now had my car over 5 weeks. The last time I heard anything from them, 3 weeks ago, the issue was with coil packs.... The car developed a miss fire and pluging in my OBD-II tool, it reported a miss fire on #2 and #4. When the MB mobile mechanic arrived his Xentry showed...

Hi All, I've never undertaken this job and would like any advice on which kit to buy - and any tips on using it if possible! I have a couple of Petrol engines as well, so it'd be handy if they were dual purpose - or are they all if they work for diesel? Many thanks in advance. Cheers, Paul

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...

So, i went to start the car last night. It compressed once then sounded like it lost pressure when cranking. Oh fun...Went to a friend to borrow a compression tester and sure enough, 30 psi on cyl 1, nothing on cyl 2. By this point i was getting very wet in the rain in my drive and decided to...
