What Customers Say
Definitely recommend Darren. My engine light on my BMW has been on and off for weeks, couldn't get to the bottom of it. Was told the DPF needed cleaning so got in touch with Darren. He came to do the job only to find out my twin turbos had not been installed properly by a previous garage... Darren fixed and connected them both back on for me. I am absolutely over the moon. Very professional, helpful and friendly.
Had a DPF clean on a Ford Kuga which needed it. Darren phoned in advance as to when he would arrive, explained throughout the procedure and what to expect afterwards. No pushy unnecessary sales spiel, totally genuine and honest... Thank you so much for coming out on a Saturday morning. My personal rating 101%.
Rather sluggish 2L Passat in for a remap and carbon clean, giving it over 100 extra bhp and over 160nm of torque with instant fast reaction throughout the entire rev range. Even when in high revs the car felt smoother and managed to come out with even better fuel economy too. Great remap, worth every penny and more. I highly recommend.
