So yesterday afternoon I head over to my good friend Mr uber's house for both car and non-car stuff. So as I am about to leave (this is now early evening) I start the car, it runs for a couple of seconds and I just say goodbye to uber, and as I look back at the instruments in my car I see that the battery light hasn't gone out, so I thought that's not right. And I think, the reasons for this could be a stuffed battery, stuffed alternator or the belt has come off. So I turn off the car opened the bonnet and low and behold the main belt is no longer on the pulley. So that would be the reason why the battery light did not go out, as there is no belt driving the alternator pulley so battery not charging. For those of you that don't know this is really bad as this the main belt in the front of the engine that also drives the powersteering pump and very importantly the water pump, so no belt no cooling.

So now what your (my) normal friends would do is offer to keep the car there till you can organize to have it towed to wherever you choose on say monday morning and give you a lift home. But this is uber we are talking here, and he and his dad had no problem with getting their hands dirty to get to the bottom of the problem (I did not even have to ask), I mean sure the belt is off, but is not really the problem, the problem is: Why is the belt off in the first place? So uber's dad fiddles around with the belt a bit, and is able to get it back on the pulleys. That is definitely not right as you should not be able to just slip the belt back on, you would need to de-tension the tensioner before you can do this, so something was not right.

Getting the car in front of the garage so that we can get more on light on the matter, we quickly found the the whole top hydraulic tensioner is almost completely loose. So we proceeded to remove the intake snorkel and the fan, to get a bit more room to work. Removed the bolts that just seemed to be barely keep the tensioner in place and removed the tensioner, and this is what we found:
The whole mounting bracket is broken in half:

The rest of the bracket:

But more shocking that this is this:
This is what was removed from the block, the remains of the big bolt that was supposed to hold the tensioner in place.

Thankfully we had uber's dad there to very skilfully remove the remains of the bolt from the block. (This would have taken me ages and I probably would have ended messing it up further)

And thanks to uber and his dad we were able to quickly and very painlessly sort out the biggest problem, now I just need to get parts to refit and get my car back on the road again.

I would just like to thank uber and his dad again for the help (on my car and for helping me out with 540i parts in same day) the hospitality and for their inconvenience of my car sleeping at their place for a while, while I source parts, I really appreciate it.

I am just glad this happened there and not on my home on the highway as you don't really want to stranded next to the highway in the middle of the night.

And my car now also gets to spend some time with the best possible company next to the e24 :=):

We ended off the evening with ice cream with chocolate sauce.
(Pic or it didn't happen :grin:)

Wow, that is probably the best place in the world to have that happen! Anywhere else would have been a major headache.

Uber comes to the rescue, again :thumbsup:

You have a good car, it knows where to break, lind of like having a symptom in a hospital.

Good care is right there and immediate.

and icecream too :)

did you find any reason for it to snap like that? seems a bit odd to me... if it was normal fatigue it should be a common problem...

Uber's dad reckons the bolt went first and that means that all the strain was just on the bracket and it just gave in eventually. Who can say what happened to the bolt. There is also the possibility that someone that worked on the car before might have stuffed it up, leading to this happening.

(remembering that the one bolt on my starter motor was also damaged.)

that makes sense... hopefully it was the bolt and it does not happen again...

maybe you should replace all the bolts every time you work in that area seems someone tightened the crap out of them...

That does sound like a plan, either way, when I source part I am thinking of trying to get prices for the belts as well, might as well replace them while I am at it, and thinking of doing the waterpump seeing as it is only a couple more bolts.

Yup I have made sure to bestow rep points on uber, they were well deserved. (Still owe him big time though :bouaaaaah: )

Yeah Uber and his dad is the man! (or the men I'm not sure) :=):

One thing though, if I had any of the M54 variant cars (E46,E39,E38) I would have that pulley on mine checked out, just a thought to the guys owning those type of cars.

Big up to Uber and his Dad! This is fantastic!! And well spotted - can just imagine how much worse this would have been if you had simply driven off!!

The bolt will not break due to tensile weakness if correctly torqued , or even overtorqued say 30 % , so it could have been overtightened . A sideways force due to excessive belt tension will cause compressive stresses and breakage is in the sideways direction . Looking at the picture of the piece of bolt which looks as if it broke off in a sideways direction I would expect overtension . This may cause shyte with bearings in alternator , power steering pump and water pump .
+1111 for Uber and family :=):
