For the first time in my ML270 18 years on the road, it has failed it's MOT yesterday. I rather thought it would fail on emissions and did quite a bit of work on the fuel system with cleaners etc, it flew through, recording 0.5, however. Left hand rear spring is snapped. Bottom coil detached itself. The really annoying thing is I replaced both rear struts 3 years ago. Due to weather and being a bit weak now due to illness ( not COVID ) I am going to have the garage do it, they are sure they can replace just the spring as have a decent spring compressor which is a floor mounted one. There is also some play in the front off side lower ball joint, and as I have one already going to get them to do that as well, parts and labour will be about £300. It hurts a bit to let someone else do it and pay the bill, but as passed retirement age, do not want to do these type of jobs now. If I did it myself, would have to buy a strut compleat, which is about £150, then spend a whole weekend grovelling about on the concrete.
