Very professionnal and quick service. My ABS pump have been fixed about one week including the send and the back of item and for an affordable price compare to Audi garage. Thanks !

Great service, good communication and quick turn around. Highly recommended.

Well what can I say as the title suggests really. From the start of my interaction with this company I could tell the level of service provided! The repair and transaction was soo easy ECU testing send the parcel company to collect your part the day after you fill out the online form (SO EASY) and within 2 1/2 days later I received my once faulty item fully repaired and after fitment I could not have been happier. So a big thanks to ECU Testing!

First class service. Updated at every stage on it’s way to being repaired. Five days from start to finish. My L200 is back up and running, Great job fully recommend. John H .

I am really happy with the service ECU testing have provided. My car part was collected repaired and delivered back to me all with in a week. They kept me updated through text msg and e-mail. A very reliable company who also have reasonable charges.

The service is efficient and they inform you on the status of the reapir every step. Sent in my ECU on the monday and got it back thursday morning fully repaired. I had exhausted all avenues of repair options with mechanics and technicians, as nobody could fix the problem and other ECU repair centres had turned me down as they couldn't repair honda ECU's. I would rate this service 5 star excellent.

I had the common abs pump faults on my BMW 130i. I sent it to ECU testing on Thursday and I received it back on Saturday good as new for a fraction of the cost of a replacement. I’d definitely recommend their services

Removed unit on Sunday, in the post on Monday, it was diagnosed and fixed by Thursday so had it back Friday ready to go back in the car within 5 days! Delighted to have a warning-light free instrument cluster again! Thank you ECU Testing!

Excellent service, faulty abs pump arranged & collected by company on Monday, returned to me repaired on Thursday. Text updates were sent to me on every stage of the repair, very polite and helpfully customer care via telephone. Brilliant company & excellent service, thank you.
