Dealer-level diagnostics, without the dealer price.
Full main-dealer scan tools across every major brand - we read what your warning light is actually telling you.
A warning light is never the fault - it's a message. We use the same brand-specific diagnostic platforms the main dealers use (BMW E-Sys, Mercedes Star, Audi ODIS, JLR Topix, Porsche PIWIS) so we read the actual fault, not a generic OBD code. Then we tell you the truth about what's wrong, what it'll cost to fix, and what can safely wait.
What's included in a full diagnostic
- Brand-specific scan across every control module - engine, gearbox, ABS, airbag, body, comfort
- Live data review (sensors, actuators, adaptations) - not just stored codes
- Visual workshop inspection of the issue and surrounding components
- Written summary of findings with a quote for any repair work
- Honest advice: what's urgent, what's wise, what's optional
Common faults we solve
We see the same patterns hundreds of times a year. Most of these are over-diagnosed elsewhere and ramped up into engine rebuilds when the actual cause is a £40 sensor.
- Engine management lights that 'come back after a reset'
- Limp mode and reduced power warnings (turbo, boost, EGR, DPF)
- ABS, ESP and traction control faults
- Mercedes ELV (electronic steering lock) and start failures
- BMW battery registration, charging system warnings
- Audi/VW DSG gearbox mechatronic faults
- Random electrical issues - intermittent shorts, parasitic drain
Why specialist tooling matters
A generic code reader will tell you 'P0299 - Underboost'. That's where the conversation ends in most garages. Brand-level tools tell you which actuator, which adaptation, which value is out of range - and let us fix the cause, not the symptom.
