What we do

Diagnostics and coding, done properly

Every job below is carried out on site with professional diagnostic equipment, so there is no waiting around and most visits are sorted in one go.

01

Full diagnostics and fault finding

All makes and models. Fault codes read, live data checked, and the actual cause explained in plain English.

02

Coding and personalisation

Enable or adjust hidden features on your car, where it is supported. We will confirm what is possible with a quick check before any work starts.

03

Adaptations and resets

Steering angle, throttle, brake wear and service reminder resets after repairs or servicing.

04

Battery registration

BMS reset for start stop systems after a battery change. A quick job, usually done in about 10 minutes.

05

DPF forced regeneration

Forced regen for diesel particulate filters that will not clear on their own.

06

Pre purchase inspection

An electronic health check before you buy: fault history, module versions and any hidden issues.

The honest catch

No overpromising on coding

"If your car supports it" is not a sales line, it is the honest answer. Coding support varies from car to car, and we check yours before quoting.
