Get in!! ABS fixed with a hammer thanks to you guys !!

I've just logged on to start a thread about a problem with my 06 GS that started this morning, but this one is so similar I might as well add to it. Just after hitting the London traffic after my usual thrash from home the red triangle of death appeared along with flashing Brake Failure. I also noticed the speedo had stopped working except the odd flick of the needle. A quick dab of the brakes to see what I had and all seemed good but I still pulled over at the next safe spot and had a quick check over and nothing seemed wrong. The brakes were working normally, even the servo, so I switched off, restarted, and the warning lights were gone, only to reappear a further mile or so up the road when the speedo once again started playing silly buggers. I reckon in my naive lack of knowledge that it's the speedo sensor causing the Brake Failure light to come on, something to do with the ABS maybe (because the speedo wasn't working). It could just be that the bike is absolutely caked in shit after leafy Kent has experienced weather of Northern unpleasantness. She's 65K old so something or lots of things could be knackered and also last night on the way home I hit a boulder in the road (it suddenly emerged from between the wheels of the car in front) at about 50 that caused a bit of a heart in mouth moment. Anyone got any ideas what my new fault is? Thanks
 
Check the wheels are not damaged!!! :o

Mine at similar mileage has had the speedo sensor playing but it's now working again. :nenau

I'd expect the actual sensor to work or not work (its a transistor) so I'm guessing the connecting wire might be damaged somewhere along the line.
 
Just to throw a a spanner in the hammer fix thread ,as predicted by some the fix was only temporary 😔normally brake failure light goes out after self check and riding off but solid brake failure appears any where between 3 and 12 miles .don't think it's rear sensor as speedo fine and TC still works when failure light is on .Another member posted recently that he took his bike to motoscott nr Luton and had abs pump stripped and fixed while he waited,as I'm only 20 mins from there I will have to bite the bullet sometime and pop down .pretty crap really on a bike with 17 k on it also with a wanked fuel strip as well 🤐.still best bike to ride since I started in 1978 so doubly annoying.
 
If there is a sticking motor brush, clouting the casing will only ever be a temp. fix IMO.

If you have the "Failure" light on, no ABS and a working Speedo then,
freeing off the brushes is the likely and best long term fix.
 
Older bods will remember electric fuel pumps on cars. They were always mounted around the bottom of the tank/wheel arch area.

The points in them used to become sticky and fail to pump, which resulted in you having to lie in the road and hit it a thump with a wump of wood
carried for the purpose. Was a common sight and great fun in a line of traffic.

I had one of those on an MG Midget 1275 and on a Mini 1000. Both had new contact points but had to be replaced. Another top product from Joe Lucas Prince of Drkness.

Motoscot did my ABS pump too (on an '07) earlier this year. Not while I waited as it was with a full service but the whole lot took them only a few hours. I'd recommend them without hesitation. My bike had only 21k on the clock so don't feel too bad about yours failing at 17k. In fact there's a theory that the less the bike is used the sooner the pump goes - not sure whether that theory's got any evidence to back it up.

Steve at Motoscot told me he'll no longer replace fuel strips because the main dealer he gets his parts from won't honour the parts warranty on the new fuel strip when it proves not to work, as is apparently often the case. They'll honour the warranty only if they fit it themselves. So if you want that fixing you're probably going to need to go to a main dealer (or elsewhere).
 
Thanks for that sproggy,will definitely have to pay him a visit ,fuel strip just a pain with permanent warning triangle,on I use trip like in the old days and wouldn't replace strip unless BMW make it reliable. Oh and before anyone says tape over warning light ! Great till something else goes and you'll never see it 🤔
 
The fuel strip presumably has a variable resistance. So if you can find out the resistance it offers when the tank is full (or, at least, not empty) you could disconnect the fuel strip wiring outside of the tank and bridge the wires with a resistor with the appropriate resistance. Then the dash won't display the warning triangle for fuel level reasons but the facility will still exist for any other issues that crop up.

Not quite that simple. Look <a href="http://advrider.com/index.php?threads/fuel-strip-spoof-results.1040056/" target="_blank">here</a>.

There's nothing in that link that suggests it's anything other than simple. OK, if you disconnect the strip heater then you need a second resistor to spoof its presence rather than just the 2k one but it's hardly complicated.

I would like to take the resistance readings from a working fuel strip. Then a suitable gauge output could be delivered by a microprocessor or even a set of ballast resistors.

It's been shown that 2K spoofs a full tank reading. It would be nice to know what resistance gives the empty tank reading

The trip is fine until the speedo sensor starts acting up. You then run out of fuel having covered "only" 150 miles. Which is why I've been working on a float gauge.
 
I reckon there'd be a market for a simple plug in gadget knocked up by an electrical minded bod to plug in instead of fuel strip 🤔

The biggest issue is getting a suitable plug so how hard can it be?

It looks like the tank full reading is 2000 ohms. If tank empty is 1800 ohms it would be a simple matter to connect up a sliding float gauge with ballast resistor. Ive bought some trimmer potentiometers to have a fiddle about.
 
fixing ABS with a Hammer

I don't know what Idiot came up with this one !!!!

We repair these units , if you hit it with a hammer it cracks the magnets in the motor and makes it impossible to repair
STOP using a hammer

We can repair these units , also improving on original design so that this fault wont happen again

for Repairs give us a call ( don't hit with hammer)
