This is the second or third type I have seen a thread saying not to use the R134 in a mercedes diesel but I have had my 76 240d converted over for three years without problems and it seems to get colder than with the R12 (it was leaking with the R12 and I converted when I had the system fixed).
Is it just certain systems or am I going to have trouble with mine in the future?
I have not dhecked the evaporator or rear suspension just the things I knew about for the 115 and 123 bodies. Thanks
