Electrical & Battery Repair
European cars run dozens of computers on multiple CAN, FlexRay, and LIN buses. When something goes wrong, it usually shows up as a weird symptom on the other side of the car. We have the tools and the patience to trace it.
Signs you need electrical repair service
- Battery dies overnight or after a few days parked
- Random warning lights that come and go
- Windows, locks, mirrors, or seats stop working
- Hard start with a slow crank
- Headlights or dash dim at idle
- After a new battery, you got a 'register battery' message
What we do
- Battery, alternator, and starter testing and replacement
- Battery registration and BMS coding (BMW/Audi/Mercedes)

- CAN bus and module communication diagnostics
- Wiring harness repair and connector replacement
- Comfort module, BCM, and instrument cluster service
Why Denver chooses us
We don't replace modules until we've proven the wiring and power/ground are good. Most 'bad module' problems are actually a broken wire or a corroded connector.
