2005 Audi A4

The B6-generation 2005 Audi A4 pairs a turbocharged 1.8T or 3.0L V6 with Audi's full-time Quattro all-wheel drive and a dense network of control modules that expect a battery in peak condition. Voltage-sensitive electronics in Audi vehicles can produce misleading fault codes when the battery begins to weaken — codes that look like sensor or module failures rather than a simple battery issue. OKC Mobile Auto serves Oklahoma City area Audi owners with mobile battery replacement, handling the coding and installation on site.
