Auto electrical work most garages refuse to touch.
ELV repairs, short circuit diagnostics, parasitic drain, modern car electronics - the difficult faults are our normal Tuesday.
Modern cars are computers on wheels. When the electrics go wrong, you don't just need a mechanic - you need someone who reads wiring diagrams, owns an oscilloscope, and has the patience to track a 0.3V drop through 40 metres of loom. That's our job. Most of our auto electrical work comes from other garages who've reached the limit of what their scan tool can tell them.
ELV (Electronic Steering Lock) specialist
Mercedes W204, W212, W221 and similar models suffer well-known ELV failures - usually presenting as a no-start, no key recognition or steering lock stuck. We repair the ELV unit itself (not just replace it with a £600 new part) and reset it correctly. Most cars in and out the same day.
- ELV motor and circuit board repair
- Steering column module reset
- Key recognition and immobiliser sync
- All Mercedes platforms covered
Short circuit and parasitic drain diagnostics
Battery flat overnight? Fuse keeps blowing? Random gremlins? We strip the problem methodically with a multimeter, scope and brand-specific scan tool until we find the actual fault - not 'we replaced the battery and it seemed OK for a week'.
Battery and charging system
- Battery testing and replacement (with proper coding/registration where needed)
- Alternator output testing under load
- Starter motor and engine cranking circuit checks
- Smart-charging system diagnostics (BMW, Audi, Mercedes)
Modern car electronics
- CAN bus / FlexRay / LIN bus fault finding
- Module coding and adaptation
- Key programming and immobiliser work
- Comfort module faults (windows, locks, mirrors, seats)
- Sensor and actuator testing with live data
