Customer Testimonials

TR6 PI tune up

Just wanted to say a huge thank you to Elliot and Eric for the great work they did with my TR6 PI. The car runs smoother now with good throttle response. Will hopefully see better fuel economy as she was running very rich. Both are friendly and knowledgeable and I have no problem in recommending them to others.

P38

Dear Elliot, I am so appreciative of your complete transformation of my P38. The 500 miles round trip from my U.K. home was inconsequential when receiving such knowledge and attention to detail. My anxieties of the numerous systems were alleviated within minutes of becoming acquainted with you. The return journey from your premises to Co Durham exceeded all expectations of how a P38 can actually perform, if maintained by a high caliber diagnostic center such as Turners. On time, on budget and a pleasure to deal with! Yours sincerely, Stephen Tomlinson.

Turner Diagnostics transformed my Range Rover P38 exactly the way I had wanted and some...

My Range Rover P38 4.6 (Thor engine) had a known flat spot of factory origin, really noticeable when pulling away from roundabouts/junctions and especially without having stopped fully. My commute of 34 miles each way includes fourteen roundabouts (I go right across Milton Keynes) so this was a real frustration for me... I talked this through with the Elliott at Turner Diagnostics, and they came up with exactly what I asked for, which was re-mapping that took all that flatness away - none of this higher revs and extra power stuff which I did not need. My P38 is now a different and much more gratifying drive - I am delighted!! As a bonus, I can also attest that I have reclaimed around 10% on the MPGs as well... that's more than Elliott and co. had suggested would be the case after the re-map! To anyone with a P38 in particular I highly recommend the remap by Turner Diagnostics... I should have had the work done a lot sooner, and I liked the fact that there was no over-selling from them... it was sorted in a day, was a pleasure all round and still is!

I wanted to say thanks for the work on my P38 RR

I wanted to say thanks for the work on my P38 RR. You sorted out a number of problems and spotted a couple more issues that needed fixing - The car drives and handles so much better now and labour charges were more than fair. Also appreciate Elliott's help when called with honest, straightforward advice on some work I was doing to the car myself. Definitely worth the 90 odd mile round trip to visit you and will definitely be back if I need more work doing. Thanks again, Scott

......cannot thank you enough!!!

Excellent service thanks Elliot, the local dealership had our Range Rover Vogue for almost 4 months (on & off) & their solution was replace the whole steering column for almost £5000, these guys had it for less than 24 hours & they diagnosed & fixed the problem for a fraction of the price & what's more, they did it with minimal fuss & a great attitude!! A most excellent find, we will 'FOR SURE' being going back there!!! ......cannot thank you enough!!! ....if anyone wants to contact me for a recommendation, please fee free, they really were excellent!!! .....going to drop a few of their cards off at the local dealership, maybe they can learn something!!

great honest guys I wish I'd found them sooner

My Kia Sedona was unsafe to drive as it stalled as soon as revs reached 2500 rpm and above. Called Kia Harpenden and waited two weeks for them to have availability to run a diagnostic test. They said they could replace the fuel rail which might be the cause but couldn't guarantee its that at a cost of £1000, if that didn't work they could try replacing something else. They told me the car isn't worth spending the money on and I should get rid of it. I contacted as trusted independent garage I've used previously with other vehicles and they said my only hope is to look for a diesel specialist, so I started looking online and found Turner performance and diagnostics and went down with no appointment booked. Elliott came straight out of the garage when I pulled up outside and listened to the vehicles symptoms I described to him and to my amazement he said on the spot what he thought it was. Initially I doubted it would be something that simple because Kia had no clue supposedly. Elliott said that if I was happy to leave the car with him he'd have it fixed in 24hours,so I did. Received phone call midmorning next day from Elliott saying I needed a new injector and I could collect car at 5pm. I can't recommend Turner diagnostics and performance enough, great honest guys I wish I'd found them sooner ??? Thanks so much
