Hello all , my first time, as i have not had any problems so far with my S max until the last two weeks very cold temperatures. My car is takeing
a lot of cranking before it will start. i have tested the glow plugs in situ they seem ok, but no volts showing at the 4 pin connector on
the top of the engine. i have been told it may be a faulty glow plug controller relay. problem is i cannot locate the relay. can anyone
help me
