100% recommend this garage. I was on my way down to London on the M6 when the engine warning light came on and the engine started juddering. I came off the motorway and rang around garages in the area. Motor Diag was the only garage that could fit me in at short notice and help me continue my journey. Even despite the short notice they diagnosed the issue so quickly and then fixed my car within only a couple of hours. So fortunate to have found this garage so that I could continue my journey on the same day. They were also so polite and caring. If I lived in the area I would definitely use them again. Thanks ever so much for your help!

Very pleased with the service at motor diag, Mark explained everything and it was very obvious he knew his stuff, he repaired my vehicle quickly, even requested to keep it longer to give it another through check 😁 friendly staff, quick turnaround, knowledgeable staff and excellent prices, will definitely use again

First time I've used these guys. Not only did they phone ME back when they said they would they sorted my TPMS sensors. Unusual (I find) to get such good service. Use them!

Had a engine failure error and the car wouldn’t start. Came out on lunch to the car as I couldn’t get it going and had the problem sorted within half an hour. Running again, no errors, no problems. Top job
