Circuit High Input codes like C0185 are mostly caused by defective alternators that develop excessive voltages, although there may be other causes as well, such as short circuits that 'leak' current into a particular system from other, unrelated systems that work on higher voltages. Note that in the case of short circuits that leak power into a control circuit, there is likely to be other, seemingly unrelated trouble codes present along with the code(s) being investigated. Diagnosing a 'high input' code will always involve a thorough testing of the charging system as a first step, followed by measures to isolate the system from all other possible sources of power during resistance, continuity, and reference voltage tests.

If your battery pack voltage out of range check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system C0185 and engine control unit are in charge of monitoring a bunch of different battery pack voltage out of range, and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Audi Ad C0185 OBD2 Code

A common cause of code C0185 is the failure of Battery Pack Voltage Out Of Range, but there are several other possible causes as well, such as ;

Failures of clutch motion/travel sensors.
Faulty Crankshaft Position Sensor (POS)
Fuel injectors may be faulty
Oil flow restriction in the oil passages or the variable camshaft timing (VCT) valve body

C0185 is a kind of Chassis Trouble Code

Diagnosing chassis noises can be one of the most frustrating problems technicians face. Fortunately, manufacturers have engineered noise, vibration and harshness (NVH) diagnostic techniques and equipment to find the source of the noise.
