Every now and again both the ABS and traction control lights come on, stay on for a bit then go out, any ideas????
-
Iffy ABS sensor
Reluctor/castellated ring clogged with crap/damaged
Failing ABS ECU

Cheers Andy :y, where can I locate these :-\

your ABS sensors are on the back of each front wheel hub & on the wheel end of each rear drive drive shaft.
The ABS ECU is incorporated into the ABS modulator under the bonnet ..... pretty sure there's a maintenance section guide over removing it to send away for repair. :y

Does the speedometer stop working when the light is on?

Yes, that still works.
Edit, I mean NO it still works.

Probably just a sensor :-\ Not sure if it does it, but would specific codes come up with a paperclip check :-\
Money on the front N/S sensor :-\

Cheers Gollum, I'll do the test at the weekend :y

No, would need a talk to a Tech2 ;)

Just noticed the speedo does play up when the lights come on.

Above still applies. Sensor/clogged ring/ECU. :y

More likely to be an ECU issue :'(

Agreed - abs ecu fecked :(
-
Agreed,but worth checking the other possibilities first though. :y
-
Thing is for the Speedo output, the ABS ECU takes an average from all four wheels, so as long as at least one sensor is working then the Speedo should work normally. Any numberof possibilities would put the light on, only one will upset the Speedo :'(
-
If its post 1998 (ie, MFL or FL), my first bet would be ECU.
Note, the ECU failure (when still intemittent) can leave speedo and MID working fine.
Worth plugging into Tech2 if you have one, and looking at speed signals, but as my dear old father used to mutter, something about urinating into headlong force 9.

Thanks for all the replies :y paper clip test no good for this?

.......... paper clip test no good for this?
No. It just does engine codes. ;)

Thanks Andy :y

in my experience 99% likely a failing abs ecu - can be refurbed by bba reman

Has anyone used BBA reman for an ABS ECU repair?
my one needs done have used them before for a clocks repair on a TT and they were good, not tried them for this.
Also am I sending the ABS block plus the ecu for repair or just the ecu?

BBA are pretty good. Just the ECU to send for repair

Just the ecu needs sending,BBA or ECUtesting.com fix them :y
