Outstanding service 5/5

Car immobile - stuck in DRIVE. Removed gear selector Monday and asked ecutesting for courier. Courier picked up part on Tuesday from my home. Repair effected Wednesday / Thursday and dispatched back to me to arrive at my home Friday. Kept informed throughout. Car all fixed now. Prices reasonable and much much cheaper than buying a new part from JLR

Brilliant Service. 5/5

Absolutely fantastic service from ECU Testing. New ABS module from Ford would have cost me over £1500 + VAT + Coding. My repair cost less than £300. I took my faulty ABS module to ECU testing on Wednesday PM and it was back at my house at 9am on the Friday. I really can’t praise the service enough. Thank you so much.

Excellent Service 5/5

Thanks for doing such a good job. Service was exactly as described with the unit pick up and delivery.Unit went straight back in and didn't need any coding etc. Hardest part was bleeding the brake system.Best bit was car passed MOT today which would have had no chance with the faults. Highly recommended company.Thank you. John
