2013 Audi Q5 Hybrid Check Engine Light On: P2257, P0414, P2009, P2088, P0245, P0456 Error Codes - What Does This Mean?
My 2013 Audi Q5 Hybrid has the check engine light, EPC light, and a hybrid warning with an exclamation point illuminated. After bringing it to a local auto parts store for diagnosis, they retrieved several error codes: P2257, P0414, P2009, P2088, P0245, and P0458. The technician noted that having multiple fault codes simultaneously is unusual and suggested a possible short circuit in the wiring harness. I'm looking for expert insight into what these codes indicate and how to diagnose or fix them. Any advice on next steps would be greatly appreciated.
I agree with the technician's assessment. Begin by inspecting the wiring harness for physical damage, including cuts, abrasions, rodent bites, or signs of overheating. These issues can trigger multiple fault codes in a hybrid system like the 2013 Audi Q5.
