Doc007 Posted March 11 Share Posted March 11 Does anyone know if this magnetic diff plug (Gold Plug Magnetic Plug M22 x1.5 AP22) will fit a BMW diff plug? The one that comes with the diff has a tiny O-ring and the Gold one just has a washer? With the replacement plug would the washer need to be replaced each time it is undone?

22daz Posted March 11 Share Posted March 11 That’s the right plug, I don’t bother with a new washer each time I check and wipe. It nips up quite nicely. You will need a 1” socket or spanner. They are advertised at 26mm but they aren’t.. because they’re from the US. 22daz Link to comment Share on other sites More sharing options...
ACaterhamCalledFern Posted March 11 Share Posted March 11 I've just done this over the weekend. I've also had to order a new socket to tighten it. I also bought a magnetic plug for the sump. I got mine from merlin motorsports. 1 Link to comment Share on other sites More sharing options...
Area Representative Geoff Brown Posted March 12 Area Representative Share Posted March 12 As I stated further up the page a degree of 'intelligent grunt' is required on the mag plug to prevent a weep. I recently removed my Gold plug which has been fitted for some four years & the aluminium washer shows no wear or the groove that copper washers have after several removals/refits. If the BMW back plate has the plug mounted at a downward angle it will be appropriate to file down at least two flats to avoid the De dion striking the plug. Otherwise leakage will occur ! Best thing is to offer up the plug, tighten correctly then check & mark exactly which flats require adjustment. My diff has the angled fitment so two flats were chamfered to about half their thickness to avoid axle contact. Link to comment Share on other sites More sharing options...
Doc007 Posted April 7 Author Share Posted April 7 FYI I ordered the above diff plug and it was too small for the BMW diff. Link to comment Share on other sites More sharing options...
