Servicing, diagnostics, AdBlue faults and mechanical repairs carried out where your car is. Over 25 years of hands-on experience and a simple rule: We give honest repair advice and only recommend work that makes financial sense. Our diagnostics identify the root cause of the fault, helping ensure a reliable, long-term repair.
Time-served, experienced hands on your car, not a weekend hobbyist with a socket set.
If a repair isn't worth the money, we'll tell you. No padded bills, no vanishing acts, no ignored calls.
Home, work or roadside. No garage drop-off, no waiting rooms, no courtesy-car juggling.

An AdBlue warning is one of the most stressful lights on a modern diesel — because once the countdown starts, your car eventually won’t restart. Main dealers often quote hundreds just to look at it, and frequently replace parts that were never the problem.
We diagnose the actual fault at your home or workplace: AdBlue level and quality sensors, blocked or failed injectors, faulty pumps and heaters, NOx sensors, tank issues and SCR-related emissions codes. Where a repair genuinely isn’t worth it, we say so up front.
AdBlue warning on the dash, countdown to no-start or a blocked injector? We diagnose the sensor, pump, heater or NOx fault at your door and get you moving again without a main-dealer bill.
Won't start, cutting out or lost power? We come to you at home, at work or at the roadside and fix the majority of faults on the spot.
Interim, full and manufacturer-schedule servicing on your driveway, using quality oils, filters and parts with everything logged for you.
Engine management lights, limp mode and intermittent electrical gremlins traced properly with professional scan tools, not guesswork.
Clutches, timing belts, water pumps, cooling systems, exhausts, sensors and more, carried out mobile wherever it's safe to do so.
Knocks, pulling, squeals and MOT advisories sorted: pads, discs, shocks, springs, bushes, wishbones, arms and bearings.
We come to you, so there’s no need to arrange transport, wait around at a garage or disrupt your day.
Work is carried out on your driveway or at your workplace while you get on with your day.
Manufacturer-level scan tools and live data — faults are traced properly rather than guessed at.
SCR systems, NOx sensors, injectors, pumps and dash countdowns are our bread and butter.
Trusted oils, filters and components, with everything recorded so your service history stands up.
