What have you done to your car today?

Any pics?

Nope, it was also dark, and snowing. :p

Dad has been out there unbeknown to me and spent about 20 minutes removing the pipe the clamp was on, and then removing the clamp, and putting the pipe back... This is why he is the engineer and I'm me... :(

Haha no OK, I tried to remove the pipe but I couldn't, and spent a long time persisting at getting the clip off instead. He persisted at trying to get the pipe off and it turned out to be easier. :p

Replaced the Toyota Startup screen with this
 
Spent last night looking for the best way to fix this wiper issue..
The bolt/bush is not meant to turn, but it is. Meaning the wiper arm cannot be removed. So I took out all the air vent stuff covering it up. The bolt sits in a nice thick steel housing so my plan is to use an Hss bit and drill a nice pilot hole through the casing and the bolt itself. Then use a split pin (cotter pin?) to lock it in place without doing anything too permanent. Simply removing the pin will mean it can go back to how it was.

Before you do anything permanent try one of these

Loosen the nut off, put the two legs under the arm them tighten it down on the nut. Unless the damage they've done prevents the mech from moving the arm

Had new PS4s put on the other week, wake up today to a totally flat tyre, pump it up and hear it hissing... Nail on the edge :(

Gutted :(

Ok, so this is my wiper situation:

Cannot undo this nut, as the bolt is spinning freely. BMW say it should not be..

The underside of the bolt, and where is interfaces with the mounting linkage.

This spins with the top nut as I try to undo it.


This is my plan:

Drill a hole carefully through the mount, through the centre of the bolt/bush, and then slide in a split pin. Once this is done, im hoping this will at least allow me to remove the nut, and then I can look at how it functions in that way. BMW say it should be a stationary part, so I guess it can probably stay that way. Otherwise, I can get a replacement mount online and replace if needed.

The last time I had that happen, I dremmelled a slot along the top of the thread and used a flat blade screw driver to hold the thread and a ring spanner to undo the nut, but depends on access and how tight it is although that only took 2-3 minutes to sort out, had it not worked that your idea of the split pin actually sounds quite well thought out!

I had thought about dremelling the top to put in a big flathead, but a couple of things put me off.

There is not a lot of thread poking out, so it would probably be quite weak.
It will look a bit unsightly afterwards
Potential for repeat removal would be lower.

However, if my plan fails, I can always resort to that method :D
 
I don't understand how that bolt/threaded rod is meant to not spin freely? What is supposed to be stopping it from just turning? It's almost as though it should have a single bolt fixing rather than a threaded rod+nut. Also, when looking from the angle of the second pic, what is that on the threaded rod? Is some sort of retaining washer? I'm not convinced something *is* broken here, as it looks like there is no way of removing that nut without bolt spinning, meaning it was designed that way, and there must be a special way of removing it. Otherwise they would have used a bolt+nut combo so you had something to counter the force when undoing the nut up top.

The other thing I would be thinking about doing is removing that retaining washer, putting some pressure on the bolt (from the direction that the second pic is taken) and then turning the nut and hopefully both nut and threaded rod would come out as one?

For info, that's what the threaded rod looks like when it's not free. An unfortunately, there isn't a separate part number for it - it's all part of 61617174969 which is the main wiper linkage. The good news is that if you do need to replace the entire linkage/motor - they aren't exactly expensive for a decent second hand part.

Still can't see what is meant to counter the torque of the nut though.
 
Ah, ok I've figured it out:

The flat part is meant to keep the bolt from just spinning freely. Obviously the bolt has corroded/been done up too tightly previously which means that when the windscreen man has tried to undo it, it's the bolt has bent the flat part of the wiper linkage, causing it to just spin freely. With this in mind, I would locate the bolt back to where it is meant to sit, then put an impact wrench/socket spanner over the nut, pull/push it hard toward the flat bit of bolt/linkage and hope that this will stop the bolt from turning and allow just the nut to turn. Using an impact wrench will be so much easier for this.
 
amazing!! That makes it very clear. I was thinking much the same as you, it didn't quite make sense.

But, whatever, the guy has totally knackered it. Claiming that as wear and tear is a bit odd.

I guess BMW saw it spinning, and just said, it's not meant to be like that!

Well, it's a bit of a 50/50 I think. It doesn't appear as though the windscreen guy has been negligent as he's tried to undo the nut, and the part that is supposed to keep hold of the bolt has bent because the nut was corroded/done up too tight. The only thing he could have done is realise that the nut was done up too tightly, not tried to force it, and instead soaked the nut/bolt in WD40 type stuff and/or use an impact wrench. But really, this is going to be a judgement call as to what you consider to be putting too much force on the nut before withdrawing and trying something else.

Yeah, and their £800 bill is utterly ridiculous too. The worst case scenario is that the nut needs nut-crackering/cutting off (10-15 minutes), and a new wiper arm installed (20 minutes) with a new nut.

Even if you use genuine BMW parts, the bill should be £150 for a new wiper arm, £1 for a new nut and an hours labour - £250 would be about right. £800 is just insulting.

The good news is that you can cut your parts bill down to £40 if you use a second hand part, plus a new nut from BMW and either nut crack the nut yourself, or get a garage to cut it off in about 5 minutes flat.
