Tow bar and M performance diffuser?

As I understand it the carbon fibre M diffuser is not compatible with cars fitted with a tow bar, but does anyone know if it works with the matte black M performance diffuser?

The BMW dealer should be able to tell you if it is compatible. I have the electric folding towbar on a 540iX and fitted the M Performance exhaust and that requires a different diffuser (bigger holes for the tailpipes) but not sure if that is the same as the one you mean?

You can also often determine if parts are compatible or not using RealOEM

Thing is, they don't seem to be able to answer. I also had to inform them a new bumper is needed when installing M perf exhaust (same as you have).

The diffuser I'm talking about is partno 51192412406 Rear diffusor, matt black that goes on the M performance bumper. Concerned the folding towbar will damage the "fins". Searching different sites provides little help as I have seen some state it's not compatible and some indicate it works.

But if i understand this spec on RealOEM the matte black diffusor should work (see section 8-10):

Correct?

The way I read that is that it won’t fit as the part says “under the condition that the vehicle does not have a trailer tow hitch”

I believe that statement is regarding 51 19 2 412 405 item 10 the full CF version.

My apologies. I think you and OP are correct in that parts 8 (51192412409) and 9 (51192412406) should fit and part 10 (51192412405) would not.

Time will tell - I'm going for it

MPE + M performance black matte diffusor, will probably do the side sills as well

Will do Canuck99

Will talk to the dealer on monday so it'll probably take a couple of weeks, will update when done and post a video pre and after for those interested in what the 4-pot G30 530i sounds like with MPE. Have a decent microphone so hope to give you good sound outside and inside. Let me know if there is anything else you'd like details on.

Hei Jeg er litt i samme situasjon som deg ang hengerfeste (tow bar) på en M550i...finner nesten ingen diffuser som passer.....hvordan gikk det med deg når du monterte disse to M-Performance itemene på bilen..? Har du noen bilder? Flott hvis du kan sende noe på +4791693023

Mvh

Morten

I just bought a new 530i.
It has the lower rear carbon fibre diffuser. I want a boat and really need a tow bar. How did you go? I want to keep the diffuser, but need a tow bar.

Also, have you done any performance mods to your 530i?
