Can someone please tell me how to remove those plastic lugs that hold the rear diffuser in place..
Thanks

Do you need a trim removal tool ?

Thanks mate..Spent over 30 mins last night trying to establish a method of removal before giving up, and removing the axle back with the diffuser in place.

Bit of a pain thou, that they are not replaceable.

Knew there had to be a logical explanation..

Sorry I meant snip but you got the idea.

I agree I wish they were reusable

There has to be a method of removing these damn clips without murdering them..
Such a PITA BMW went this way... How could they install a unremovable panel clip..

Can anyone give me a quick how-to on removing the diffuser? I have a CF one on the way but it sounds like its a little more difficult than the 135i...

Haha.. I still haven't decided on the Akra yet... and if I do I'll probably get the Titanium tips so shouldn't be a problem...

I heard an Akra the other day. It sounds mental but I still feel like its a ridiculous amount of money for an exhaust...

Even the more expensive 135i exhausts cost less than the cheapest 1M exhaust...

Not sure yet... Asked Stu to find me one... The discussion went something like this:

ME: "All the diffusers out there suck. The brand name ones are ridiculously priced and I don't like most of them. The eBay ones are all questionable quality and they're stupidly priced too. Can you find me a decent one at a decent price?"

STU: "Sure."

A day or so later he told me he'd found and ordered one. That was a month or so ago. (They had to fabricate it after he ordered it.)

It arrived at Advan today and hopefully it's already on its way to me..

Now you know as much as I do... I'll report more once I've got it...

Which one did you buy?
Just wanted to add some additional information to this thread.

The OEM diffuser is attached to the bumper via 4 plastic single-use pop rivets (6x21mm): Part # 51118222901

You can snip the tops off from above where the diffuser attaches to the bumper and then work the plastic rivet head free. As Ian///M pointed out the rest of the diffuser is attached via clips which are pretty snug.

To replace them with new blind rivets you'll need something like this tool:

(Apparently the heads on HF's standard rivet gun are too small to accommodate the plastic rivet pin on these pop rivets.)

refreshing thread question

do you have to remove the rear bumper or drop the exhaust to replace the rear diffuser?

It is not necessary to remove the bumper or exhaust to pull the diffuser. Just have to be patient.
