Hello all,

I am going to view a Mondeo 51 (new shape) plate on Saturday. The owner said it has has 4 new tyres, pads and is in getting it's MOT done, however the ABS light keeps coming on. The garage is meant to be looking at this as well.

Is it a major issue if the light is on?

sounds to me like a sensor??

or could it be worse!!!!

 

it will fail an mot with this light on but it could be somthing as simple as dirt in the teeth on the shafts or as bad as the abs unit.

 

Could it turn out to be costly,

MOT, can I not just take the bulb out before it was tested?

 

most common is a wheel sensor, which are cheap, worst case is a new abs ecu, they aint cheap to buy but a piece of piss to fit yourself

 

How 'not cheap' are they?


50,100,200?

 

cant just take the bulb out as it will still fail as it should come on for around 3secs and then go off

 

not sure on a mondeo abs ecu; but i bought a audi A4 avant with the abs light on as it was cheap; Audi wanted £1052+VAT + Fitting for the new abs ecu.

i found a new ABS ecu for £600 inc VAT and fitted it myself.

ideally if you can take a mechanic with you with a scanner, you can see what the fault code is and then make a decision from that.

Also maybe be worth checking if the ABS pump & ECU are one combined unit, if they are and it does need replacing you're talking more money cos you've got to bleed the system in after fitting a new pump

 

if ti does turn out to be costly try second hand breakers tg_91 use link below for there number.

sorry we only deal in cosworth and the odd evo , ,
but thanks for the plug !

 

lol we had 1 at our garage on a A3 had the abs light on for 3 years and ended up fuking the whole system up abs ecu pump the lot lol was 600+vat just for the pump!!

- i could just be a dodgy sensor like said needs a diagnostic cjeck should tell you straight up then!!
