Some electrical faults are beyond a general garage: the battery that goes flat every four days, the warning light nobody can clear, the aftermarket alarm that a previous owner had fitted badly. We have dealer-level diagnostic tools, including for Mercedes and BMW/Mini, and the patience to trace a fault to a wire rather than swap parts until it goes away.
Typical jobs
- Parasitic battery drain — finding what's staying awake
- Removing and repairing old alarms, immobilisers and trackers
- Tow bar electrics, including bypass relays for LED lighting
- Coding and retrofitting factory options after a repair or replacement part
- Wiring repairs after rodent damage or a previous bad installation
- Auxiliary power for dash cams, fridges, chargers and van conversions
If a job needs a main dealer, we'll say so — but most of the time it doesn't.
