Has Mercedes Always Been This Bad?

jshepguis:
A friend who has recently retired and sold on his haulage business told me one of the big problems hitting the industry, is the availability of good experienced technicians/fitters whatever they are called nowadays.
He says youngsters not coming into the industry and a lot of them, if they can’t find the fault plugging in a laptop don’t know how to start trouble shooting!

To be fair sorting out a failed injector from loss of compression and even which/how many cylinders are down was never easy in the case of a diesel engine and modern ones need the computer even to sort out the basics.If the thing won’t start at all it obviously gets even more difficult.
