Customer Testimonials

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

Thank you so much Turner Diagnostics

Thank you so much Turner diagnostic, my Vauxhall meriva came in jumping down the road and I've come out jumping for joy that it's stopped you truly looked after myself and my car. Being a woman it's always daunting going into a garage but I am very impressed! Thank you again I will be coming back and will be recommending you to all.

Cant thank the guys at Turners Enough

Can't thank the guys and Tuner Performance more, my Astra VXR went in with an emissions fault, with a last minute rush before my MOT they had booked me in on the same day and had the car back within 2 days completely faultless, mapping re done, emissions fixed! Car pulls like a train and makes an incredible sounds due to the pops and bangs I added to the mapping! Fantastic work and will for sure be back for some more work in the near future!
