Our Services
From advanced diagnostics to remapping, DPF cleaning and window tinting — everything your vehicle needs, all in one place.
Engine Diagnostics
We read every fault code, trace every signal and identify the true root cause of warning lights, limp mode and drivability issues — quickly, accurately and with no guesswork involved at all.
ECU Remapping
Custom ECU remaps via VIEZU deliver more power, better fuel economy and improved drivability — written specifically for your vehicle's engine, never a generic file, backed by a 30-day guarantee.
DPF Cleaning
Professional on-car DPF cleaning restores performance, reduces emissions and improves fuel economy — saving you the cost of an expensive replacement, diagnostic included.
Window Tinting
Premium standard, ceramic and nano ceramic window films improve comfort, privacy, UV protection and security while giving your vehicle a sleek, factory-style finish that lasts for years.
Diagnostics
Your Engine Is Talking. We Listen.
Modern vehicles generate hundreds of fault signals that most garages simply miss or ignore completely. We read every single one using precision professional diagnostic tools and software.
We don't guess, we don't swap parts blindly hoping something works — we trace every fault back to its root cause and fix it correctly first time.
No warning light gets ignored, no symptom gets dismissed. Every diagnostic job ends with a clear explanation of exactly what was found and what needs doing next.
DPF Cleaning
Don't Replace It. Clean It. Drive Again.
A blocked DPF doesn't always mean you need an expensive new one fitted. Our professional on-car clean fully restores filter flow, lost power and fuel economy.
No dismantling required, no workshop delays or waiting days for parts — we come directly to your location across Somerset and have you moving same day.
Most vehicles see an immediate improvement after a single clean — better throttle response, reduced smoke, lower fuel consumption and no more DPF warning light on the dash.

Trusted by Drivers Across Somerset
"Absolutely transformed my van. More pull from lower revs and noticeably better fuel economy on motorway runs. Adrian really knows his stuff — no upselling, just results."
"DPF light had been on for weeks. Main dealer wanted £1,800 for a new one. Adrian came out, cleaned it on the drive, light gone same day. Unbelievable service."
"Three garages couldn't find the fault. Adrian diagnosed it within the hour, explained everything clearly and had it sorted the same visit. Wish I'd called him first."
