ABS fucked up MOT woes

[Deleted account 190117001]

If you maintain a good relationship with your MOT tester you should
be able to put the bike in for the test with no worries.
Arrive at test station,
tell the tester (honestly) about any minor issues.
He will have a giggle and tell you to take the pile of ancient shit somewhere else.
Bike will be booked on the computer.
Coffee will be made.(by you )
A large box of chocolate biscuits will change hands.
Biscuits will be eaten.
Piss taking will commence , coffee will be drunk.
One or two serious questions will casually be asked.(how thick are the brake disks ,is a common one)
These questions will be answered truthfully,
and are there to see if you know about your own bike.

More piss taking.
Including slagging off his hardley movingson in the corner.

My MOT tester knows i will not take him a dangerous antiquated piece of Bavarian shit.

MOT ticket will be printed, money will be handed over and you will be told to fuck off and next time bring coffee not just biscuits.

i phone up on friday and let him know i'll be there at 8 am saturday morn when he opens (no-one else around )
we have a quick chat ,about 4wding, fishing and kids - he then checks the mileage and writes the ticket out.


You make your own luck ...

I've two places i get bike mots from.
They both call me if they get a BMW in that they can't diagnose.
Hence at MOT time we just end up bitching about customers while the mot clock ticks down.

put a multimeter on the sensors in Ohms range Front one is up right side of bike behind the oil cooler usually on the fairing brace that runs to the alloy frame the rear one is on the frame rail just under your right buttock under the saddle again cable tied to the frame rail

They should both read the same approx + or - 15 ohms

If the ABS rings are clean and no teeth missing / or debris in them I can nearly guarantee its the rear sensor?

For some reason I have had a spate of them this last 3 months all the rear sensor

Have you had tyres fitted recently it was the only common factor in the three of them

A quick test is :- If someone nearby has a good working ABS sensor just plug it into the loom and try it. From memory I didn;t have to clear the fault it can see both sensors so the system OKs itself and the lights do what they should

TO Turn off the lights temporarily Remove ABS relay and If you pop off the ABS control plug and find the green wire that goes to Pin 15 and carefully cut it so you can join it up again (while you are at it route a bit of twin core cable back to the fuse box You can install the ABS check after engine running modification with a relay and another 20 mins of poking

I go with removing abs relay (blue) to turn the ABS warning light out. I also go with removing the ABS connector from the control module, that should put the General Warning light out.

However, IMHO cutting wires at this stage is a bit deep. If you leave the connector unplugged there is no need to cut the wire.

He only wants to get it through an MOT, with a view to fixing it at a later stage.

The only reason to turn off the ABS lights is if they get on YOUR nerves.

The MOT tester wont care. Put it this way... the lights flash even when working correctly. The MOT tester isn't going to take the bike for a spin. or ride it far enough for the ABS to self test and engage. so.. switching off the lights is pointless.

Register it in France, we don't have an MOT test, (yet).

I agree, but he has already told the tester he has an ABS problem.

We don't know who the testing station is. If it were a BMW franchise then the tester might spot the ABS is faulting. Ie alternate flashing as opposed to flashing together.

If there are no lights, then he could at least argue the ABS has been removed.

Yes Ian Agreed about not cutting wire "BUT" I would rather cut the wire and tape it to prevent accidental contact (or solder the wires to a new two core cable fed back to the relay/fuse box) with the view to reconnecting at a later stage than to leave the ABS ECU itself and connector open to debris and moisture on the holiday

but as already posted abs fault is an advise, so it matters not how good the tester or even if he is an expert in Bmw, Vosa say it's a pass and advise, so that's what the tester has to do

If only things were that clear. Like lots of things this seams to be down the MOT testers interpretation of the rules.

In posts 6 and 7, I get the sense that the tester would probably fail the bike.

If the tester had stated the bike would pass with an advisory notice, then I don't think dubster would be in such a panic about getting this sorted.

On the basis of what I've seen here in posts, I would be inclined to bite the bullet and take it for MOT as the bike is and if he tries to fail it, ask for clarity. Not much comfort though.

FFS! 4 fucking pages devoted to whether it will pass an MOT or not...and only a few replies as to how to fix the bike?

Check operation of the rear brake light switch?

 

[janitor]

Can he not disconnect the lights, and take it to another MOT station.

FFS!
I guess you didn't read the bit that said it's not a servo bike then?

There's been plenty of input regarding things to test (and a fair few red herrings from people who can't read). We all eagerly await dubster's post regarding his latest tests.

It's a power on self test issue which greatly restricts the choice possible failures. My best guess is an abs sensor wiring fault.

 

[dizzyrascal]

MOT tester !!

In the first instance particularly due to the time restraints the most obvious thing to me would be to take the bike to a different MOT station, they are not all the same and will interpret the same problem differently.

My wife had her car failed because there was a fresh air thing hanging from the rear view mirror, the tester did not remove it and actually wrote down the reason for the fail on the paper work, needless to say it took less than a second to remove for the re test.

It's not down to the tester vosa make it quite clear in the manual, Vosa tell them how it's going to be, if the tester thinks otherwise then tell him you will appeal to Vosa, the tester will then pass it, just to avoid the bolloking from Vosa

The tester has discretion in a lot of things, but they can't re write the manual

The manual says!

The vehicle presenter should be
"advised of any defects found on an ABS system"

Bottom of section 3.1

What time is it booked in

I have to go out in the afternoon
and must know if it passes before I go

My money is on a pass

You should try reading the posts before adding your tenpenny worth of wrong information. .

 

[dubster]

Thanks for all the replies gents.

I'm starting to think it must be a faulty sensor, as Dr farkoff suggested, since i recently did fit new tyres. Everything else I've checked and double checked (sensor gap, battery etc)

Had another chat with MOT geezer today and hopefully can pass the bike with an advisory.

Thanks again to everybody. Much appreciated.

Correctimondo The world is full of testers who think they know better, usually just before you tell them to go and read the feckin' manual.
