Hello again everyone

I have joined the growing club of miggy owners who has the abs and traction control lights on, which indicates that there is a problem with the ABS pump or ECU.

My first query is, which would it be - the pump or the ecu.  When driving in the snow I wasnt getting any abs at all and this was a bit nervy however Im old school and remember driving cars without abs lol.  Would one or the other cause this or is it still hit and miss which one it is. 

Following on from this is, i will be trying to replace the unit myself, not an easy job by all accounts but i will give it a bash. 
I am aware that there are so many different ECU's and pumps for each model.  To take the confusion away from all this I was pondering sending it off to be refurbished instead of buying a used one (Vx new beyond finances). 

If i did this will it come back with all the correct programming for the car or would it need a tech2 session.  Secondly, does anyone know or can recommend a company that does this job and the rough cost that I would be expecting to be charged for the refurb.

Any advice on this would be grafefully appreciated.

Cheers Entwood  ,  I take it i send the whole unit, pump and ecu together?

Thanks for the contact details I shall give them a buzz.

Do you have any idea how easy it is refitting the unit.  Should i expect problems with air locks etc or is there any trick or advice for this.

That will do nicely Entwood cheers.  I dont mind scraping a bit of skin of the old hands and thanks for advice about not taking whole unit off, it sounds like that would be a right pain in the rear and no doubt i would of if you hadnt said.

I will give them a ring and see what they say.

Thanks again Entwood 

how do you know it's not a wheel sensor.

In all my time test-driving or when I had the garage - I've never changed either an ABS ECU or a hydraulic "block". I'd class them as spectacularly reliable pieces.

have probably changed a couple of hundred wheel speed sensors tho

Thanks for the advise, Im still al little unsure as to what the isssue could be, sensors or the ECU unit for the ABS.
Just to add a little more info, every now and then, probably every three or four journeys, the speedo may work and the tc and abs light go off.  This is usually only for a couple of minutes at the most and then its back to normal - warning lights on etc.

Could the ECU still be at fault or is it more likely to be a sensor failure. 

Agreed abs ecu furbared

I got ABS ECU from breakers for £60. Perfect. You need to match the prod code exactly - many variants - otherwise poss problems.
