ABS fucked up MOT woes

If you take it to an different test station tape may work - but if the same tester he might just notice the tape and fail you again. I'd just whip the bulb out - no way he could know its not fixed then.
Don't go leading yourself up blind alleys checking for stuff that doesn't apply to your bike (read Steptoes post 16 earlier). Things like brake levers and bulbs only apply to servo bikes.
I think pulling the ABS warning relay in the fuse box will put the lights out.
Try it!

So just fuck the MOT and bring out the plumbing tape?

Ian, please elaborate.
Which fuse?
Which fuse?
.. and cables are fine. Spoken to my local MOT geezer and a piece of tape aint gonna cut the mustard
There's no requirement that abs works, it's not even mentioned in the testers manual, nor is any lights flashing an issue, these are a requirement for the car mot, they are not mentioned in the bike mot

I haven't looked, but seem to remember something in the manual about 'inappropriate repair to braking system' being a fail - i.e if a component isn't working correctly its a fail..... But if it all "appears to work correctly" it shouldn't fail - if the light don't flash it works ok
Sorry bit of misdirection there, the fuse 1 is used for other services.
Removing the blue ABS warning relay should put the ABS warning light out.

take the bulb oot the warning light pour yourself a large 
one jobs a good un

My 1150GS passed an MOT last month with the lights flashing away (and ABS not working). Never even batted an eyelid at it. Same are yours though, it's doing it on the turn of the key rather than pressing the starter but I've not worked out what is up yet and it's not resetting.
Likewise, mine has done this every year since I got it. Unless I gave it 5 seconds after turning the ignition on before pressing the starter button, it used to fail its abs self test every time - the MOT tester never did this
I've got a MOT tomorrow - a new starter motor means for the first time the abs is likely to be working - wonder what the tester will do?

So I quote the official MOT testers manual, and to prove me wrong you quote an advertisement from some mot station?
I think I win at top MOT trumps
probably not relevant but has he check dot 4 levels

I think you do
I've just done the same google search as Bill (probably).
He appears to have quoted the one result that confirmed his conjecture
Edit: he's edited his post - done a bit more googling
Some useful information
Extracted from from this source:-
http://www.largiader.com/abs/absfault.html
ABS2
ABS2 uses the same two warning lights as ABS1: the ABS light and the bulb monitor light.*
At key-on, the two lights will flash together and continue to do so until the self-test is complete (which doesn't happen until you start to ride away), at which time they extinguish.*
If the self-test fails, they will begin to flash alternately. The exact moment when the fault happens will help you know what caused it: if it happens before you start the engine it is an item that is tested at power-up. If it fails when you start the engine, it is almost certainly low battery voltage. And if it fails when you ride away, it's probably a modulator or a wheel speed sensor.
It might be worth reading the whole article. Because by using a simple 12v LED it is possible to read the fault codes. The problem could be as simple as a failed ABS relay ( the one located under the cover on the ABS module).
