ECU Malfunction 5/5

Excellent efficient service. Easy send/receive system. Personal touch via staff phone calls to validate information. Expensive, but job done! Highly recommend

Excellent 5/5

I had a failure on my instrument cluster of my Focus 2010 reg. My local Ford dealership wanted over £1600 to supply & fit a new cluster. I had initially thought about scrapping the car but apart from this problem it was in a really good condition. The service and communication from ECUTesting was excellent throughout the whole process. 6 months on from installing the fixed cluster, the car is in great condition and has had no further issues.

Repair of power steering pump 5/5

Had my power steering pump repaired which turned out to be much cheaper than buying a new pump, and also easier than trying to find a used pump, as this model doesn't appear much on eBay. The pump was returned within 5 days. Note mechanic will need to use a plug-in fault tester after re-fitting the pump to reset the steering position sensor otherwise it reports a fault on the dashboard and disables the traction control.
