fast, efficiency, and five times cheaper than a repair at opel. Thanks ecutesting !

Found ECU testing on the Internet having been quoted £700 for a new instrument cluster from Volvo and £200 for a similar unit on eBay which would have required re-programming. Item was collected by DHL when promised and back with me in about a week. I was kept advised of progress by email and SMS. All now working including the trip computer/info display.

Excellent service

Sent my Vauxhall Corsa ABS Pump for repair (no braking effort at front near-side). Very easy to arrange uplift of the defective unit. Excellent communication from the staff at every stage of the process. Returned in the stated timescale and repair at a fraction of the cost of a new unit. Very impressive service, can highly recommend.

If you have any doubts about your ECU, arrange for it to be collected and tested with ecutesting.com and save yourself time and money. I had intermittent starting problems with my 2006 Honda Accord which ecutesting has fixed. The unit was collected the day after booking it in, tested and repaired a few days later, and returned on next day shipping sealed and securely packaged with warranty.

Mercedes A180 that had the common limp mode issue, fixed and sent back in under 5 days. ECU Testing are the best in the trade.

I thank you for a first class service that was informative and carried out quickly and efficientlY. I have no problem in recommending your company and will certainly use you again. Clifford Rawlings BFW Ltd.

The ECU (transmission) for our Merecedes A Class was repaired and worked correctly for around 5 miles. Then the problem returned, the transmission workshop management light returned, and the car is unable to select 1st and reverse gears Very disappointing, and money wasted

Fantastic professional service. Part was received and immediately they kept me up to date through message and email. When the part was examined it needed fixed I was notified and it was fixed and dispatched that day. Put the part in and light went out straight away. New would have been over 1k and this was a mere fraction of this with a lifetime warranty. Couldn't recommend more.

No comms fault with the engine ECU so sent to ECU Testing. Found the fault and fixed it within the week. Excellent professional Service
