Driving to chavtown on sea today.After 20 miles ABS/TC lights came on, speedo working fine.
On the return journey, same thing after the same miles.
Assume its the beginning of the end for the ABS ECU, although surprised speedo hasnt gone wonky as well. :-/
Not the end of the world as I have an ECU here from a year 2000 2.5 which mine is, so should be a straight swap.

You need to get codes read. ABS ECU failure  generally gives the lack of speedo too, so your problem could be a failed/failing wheel sensor.  :-/ :-/

Good point Andy.I wonder if I disturbed something when I changed the rear shocks/springs last week.

Not always - when the Estate one went initially had abs/tc lights on - with time speedo operation became intermittant then packed up completely as well as loss of speed sensitivity on power steering.

Have had a look around the rear, checked the speed sensors were plugged in etc. All looks ok.
Just used the car and the ABS/TC lights are now on permanently.Speedo and PAS are still working fine so far, although rev counter seems very jerky at low revs - not sure if that could be connected. :-/
Looks like I need to study up on changing ABS ECU. Does the whole pump need to come off, or can the ECU part be changed in situ ?

...Does the whole pump need to come off,.

NO!!!! don't take the whole ABS unit off, you'd need a Tech II to cycle the ABS pump to bleed it all if you do.

 

or can the ECU part be changed in situ ?
Tia.

Yes! apparently - never done one myself 

[tunnie]

the ECU/Pump is an all in one jobbie, not a job i'd fancy doing, removed one on TB's Goldie, it already had half the engine components stripped out, still pig of a job!

No it ain`t

Ive removed a couple myself this year, but that was using a hacksaw on the brake pipes etc.Will be a bit different this time.
Glad to hear the pump doesnt need to come off.
Will have a wander in the guides section and hopefully find some  - giudance.

Yep, fiddly job. Makes it easier if you can unbolt pump from mounting bracket and carefully bend it up with brakepipes attached to access the lower torx bolts

Cheers Rob.
Not planning on doing it today.Hoping to nurse it through until Monday when I will have several days off work, so no need to rush and panic.

No it ain`t

maybe we need to re-write the guide

ive stated for some time that guide is over complicated, and wants a rewrite
