Repaired at reasonable cost Repaired at reasonable cost 4/5

The unit was sent with the test form completed, the repair was done & unit returned & re-fitted to vehicle. All working no problem. Only complaint is time it took to turn around as they were busy. Would use the again.

Very efficient service and communication. Very efficient service and communication. 5/5

Hard to think how they could improve really (other than charging less!). Very pleased.


The repair has been done on time and the unit has been installed and works fine. The company has been very informative about receiving and working on my unit by sending e-mails on the process. I have done about 1000 Km so far everything works fine. Excellent service 5 strars !!!!!

BMW M3 ABD pump repair BMW M3 ABD pump repair 5/5

Excellent customer service. Friendly and knowledgable staff. Identified problem quickly and repair carried out in a matter of hours - at a fraction of the price of a replacement unit from the manufacturer. Would certainly recommend to anyone!

Buggered in New Zealand Buggered in New Zealand 5/5

The module died and replacement quotes in Auckland were outrageous. A forum search brought up ECU Testing and their (deserved) reputation. Long story short, the entire process right from first contact was extremely well communicated. The unit was repaired and returned quick smart, it's now installed, everything as it should be. On the road again yeahhhh! Thanks for the outstanding service people you raise the bar very high. Cheer

Service Service 5/5

Excellent service, sent on Monday and received back at the garage on Friday, fitted and drove away on Friday. With a life time guarantee what could be better. BMW wanted £1500 + vat!!! ECU testing repair and updated and my BMW specialists at Wareham (Dorset) all done with repair, fitting bleeding the brakes for £385 in a gooden!

Abs pump failure Abs pump failure 5/5

I would highly recommend using this company if you want to save yourself in excess of £2000. This company proved to be a financial saviour when I discovered the the cost of getting this problem with my 2007 335d coupe sorted through BMW. The communication through the process was excellent as I was informed continually about the progress of abs pump unit.
