ABS Pump Repair 5/5

I found this service online and ECU Testing was also recommended by a local mechanic. I had a constant traction control warning light illuminated on my 2006 Mazda 3 Sport dashboard. All research and a diagnostic fault code pointed to the ABS pump. Mazda quoted £1200 to £1500. I removed and sent my unit off to ECU Testing. They confirmed a repairable fault, fixed the unit and sent it back really quickly. Very much a lifesaver!
