Any one on the South Wales area able to help me ,, c220 diesel 2008 ,, injector one leaking had two mechanics re seal them ,, they keep leaking ,, the third time I watched him and when finished ,, at idle was ok I didn’t test drive untill he left as it was early in the morning after returning I checked and was leaking again so going to get a Honda washer and try that ,,, think it’s worth gettting the injector tested or even renewed ,, I’m letting the guy try again as he said he’s never had a problem doing them ,, but if there’s any one local that can do it please feel free to help out thank you
