Hi All I havce a 1999 340 and the gas solenoid valve coil is overheating the result is the gas flow is much reduced ( now almost useless)Questions01 Is this a common fault?02 The coil detaches by one circlip from the body of the valve , if I replace this coil will it solve the problem? or does the whole valve need to be changes ?03 I am in UK does anyone know where I can get this part over here?04 The coil id a Parker hannafin item Thanks in advance John
