- W251 r class
Hi.My 320 r class is slow to start from Cold,so with a glow light on after starting I have replaced all 6 glow plugs.No light now but still slow start so I replaced the module , same again,my only concern before doing a leak test is ,replaced the original glow module which was a Merc part with a beru part and just wondered if the difference in part numbers might make a difference .Before the glow light came on it would start straight away .Steve
