Earlier this week I pulled away from the auto parts store into traffic. The car accelerated like normal, then when I lifted off the gas pedal the engine went to idle and wouldn't rev at all. Pushing the pedal did nothing. I coasted to a stop in a neighborhood, popped the hood, and verified that the engine reacted to inputs at the throttle body linkage. Since the problem was between the pedal and the throttle body I assumed the throttle cable might have broken. I called a tow truck. Fortunately it was a cheap local tow.
When I got home I pulled the lower dash cover and inspected the throttle linkage. I found the cable intact but the small rubber bushing in the pedal arm had disintegrated and fallen out. With no bushing holding it, the hook end of the throttle cable became detached from the pedal linkage. The rubber bushing (part# 35411152331) is a $2.50 item. It's easy to replace. This is a small and hidden wear part that I hadn't thought to check before (until it left me stranded). I figured I'd let everyone know. Maybe it saves someone else the hassle of a tow. This is 22+ year old rubber after all... it's gonna be hammered after many years of use. I bought one for my track car too.
Below are photos of the old bushing that broke & fell out and the new one in place in the pedal linkage.

That’s on the accelerator pedal linkage? Wow, I haven’t heard about that issue. Thanks for pointing it out.
Thanks for posting the part number, too!

This also happened to me! I wish I saw this post before it happened.
problem is that pedal stop is not adjusted properly so at every WOT bushing has to take all of the pressure of the throttle stop. It also seems that genuine bushing is harder rubber and aftermarket ones are softer rubber that does not last or falls out.
Does the bushing go in the top or bottom hole?
I checked the throttle pedal stop just now and that definitely wasn’t the problem. There’s a tiny amount of slack in the throttle cable when the pedal is fully on the stop. So like E85STI’s bushing mine just dry rotted and fell apart with age.
I'll check mine tomorrow after work!
FCP has them for $2.69

What's the emergency fix if it falls apart in the middle of nowhere? Can you zip tie the metal end of the cable to the metal of the pedal and and prevent it popping out until you get a replacement?

Yes. Unfortunately I was without zip ties when the bushing broke and a tow truck had already been called. I thought the throttle cable had snapped. While waiting I used the screwdriver in the factory tool set to remove the cover panel under the dash and look around. I found the failed bushing right as the truck pulled up. But you could certainly rig something to keep the cable end in place if it happens.

Did the pedal feel "loose" or without tension when it happened?
Makes me think I should keep some zip ties in the car in case of any emergency! Good idea importbanana!
My throttle had been feeling a slight bit sloppy recently upon initial application when starting off and when reapplying the throttle after a shift, so I took a look at it today. There wasn't much left of the bushing, just a few pieces of sticky, crumbling rubber. The arm where the bushing fits is a bit different than the OP's, one hole instead of two, but installing the new one was a snap...the worst part was refitting the finicky under panel.
I had ordered the bushing from FCP Euro back in February when I first came across this thread. When it arrived I placed it in a safe place so I could easily locate it when it was needed. At the beginning of this month I decided to swap out the bushing, but after looking high and low couldn't find the new one, so I ordered a replacement. This is the kind of stuff you deal with when you're 79 years old, just happy that I can still change oil and fix the easy to get to small stuff...

Checked mine today and there's nothing left. Time to order a bunch to have some spares on hand!
Price may be up, but check the shipping cost...FCP usually beats the others.

Today I replaced mine. Old one didn't look like it was about to fail but still good to replace it.

If you have a local dealer it might be worth a check with their parts department. Last year when mine failed 35-41-1-152-331 was $2.27 + sales tax and I was able to pick it up next day.
So, this happened to me last week as I was leaving COTA after participating in a BMW M Track Days event. I didn’t have anything available to temporarily fix it, but I searched around and found a discarded heavy wire cable (Nite Ize rubber twist tie) and my son had it installed in a few minutes and we were on our way.
I bought a new bushing from the local BMW dealer. They wanted to charge me over $6 for it, but when I showed them my BMWCCA membership card the price dropped to $2.24, including tax.
