Battery Replacement & Electrical Service
Modern Audi and VW batteries require ECU coding and registration -- not just a simple swap. We handle the complete process so your car's charging system works the way it should. One mile from Manchester on Route 101.
More Than Just a Battery Swap
On modern Audi and VW vehicles, replacing the battery is only half the job. The new battery has to be registered with the ECU so the car's Battery Management System adjusts its charging profile. Without this step, the car doesn't know a new battery was installed and will continue charging as if the old one is still there. Dealers charge separately for the coding. At Reflex, it's included.
OEM or Equivalent Battery
The correct group size, cold cranking amps, and AGM specification for your vehicle -- not a generic fit from the parts store shelf.
ECU Battery Registration & Coding
We register the new battery with the vehicle's control module so the charging system adapts to the fresh battery's capacity and chemistry.
Digital Vehicle Inspection
A full digital inspection with photos and notes -- tires, brakes, fluids, belts -- included with every service visit.
Free Loaner Car
Drop off your car and take one of ours. Every service visit includes a free loaner vehicle -- your day keeps moving.
Your Audi or VW uses a Battery Management System (BMS) that controls how the alternator charges the battery. When you install a new battery without registering it, the car still thinks the old, degraded battery is installed. It will overcharge the new battery to compensate -- shortening its lifespan significantly. Registration resets the BMS so the charging profile matches the new battery's actual condition.
Every battery replacement is backed by our 3-year/36,000-mile warranty -- three times the coverage of the typical dealer warranty.
The electronic system they have for car reports is fantastic and very informative. It lets you know exactly what's going on with your car and what needs to be fixed sooner rather than later. I was interested in buying a Golf R from a dealership that said the car had been serviced at Reflex Tuning. I reached out to the shop to ask about the vehicle, and Heather knew exactly what car I was talking about and told me that it was a solid vehicle and had been well-loved by the previous owner. I ended up buying the car and will only bring it to Reflex. It did need a few things, which they took care of quickly, and reassured me that there were problems with the car and not that I had completely forgotten how to drive a manual vehicle. They're super honest with things, efficient, and communicative. The electronic system they have for car reports is fantastic and very informative. It lets you know exactly what's going on with your car and what needs to be fixed sooner rather than later. I'm so glad that I found my Golf, and even more so that Reflex is around to take care of it. Highly recommended!!!
