Rating 4.88
Excellent value for money. 5/5

I had a customer with a failed DSG unit in a VW Polo and as usual ECU testing were excellent and provided me with good communications and a refurbed unit within a week and my customer was back on the road. Excellent service all round.

Quick turn around 5/5

Very happy with service kept well informed and quick turn around all worked out for ribbon on airbag easyily damaged.

Faulty ABS module 5/5

My ABS module stopped working and the dreaded dashboard lights flashed like a disco. I checked with VW and they quoted me £1300 to replace!I found ECU testing on the web. Very easy process, just take take off the part and they arrange collection,repair & delivery in a matter of days. At each stage they kept me informed. ECU said that they would give me 10% off for leaving a review as well! (Still waiting for this). Can't fault them!
