Hi mate,

may well be, what I would do firstly is to get the codes read from the ABS module side. If the pump itself is playing up then it will kick up a code.

Usually when the pumps fail it is the control module mouted on them that is faulty. But it is easier and quicker to replace the whole pump.

New pumps are expensive, if you need one, get yourself a good 2nd hand one. Most of our customers that need a pump do go down the 2nd hand route.

We did have a similar fault to what your getting with a customer a while back...................he was lucky and only needed a new ABS relay.
