Rating 5
Ditto 5/5

My experience mirrors all the previous 5 star reviews, - excellent communication, quick turn around, superb value for money with a £1400 saving on a new replacement. All done remotely with my dealer while we were away on holiday! I will certainly use again if our other car gives the same trouble. Keep up the good work chaps!

Amazing service 5/5

Cannot thank Ecutesting enough, car had failed its mot due to a faulty abs module. Needed the car back on the road asap and the service I got was great! Had part back and fitted in my car 3 days later. Glad I found this company would definitely use again, thoroughly recommend them.
