P0019 on Audi
Crankshaft/Camshaft Position Correlation - Bank 2 Sensor B
P0019 on Audi vehicles indicates crankshaft/camshaft position correlation - bank 2 sensor b. Au7o has documented this code across 1 Audi model — most commonly on Q7. This code means the engine computer detected that the crankshaft and camshaft positions on bank 2 (sensor B, typically the exhaust camshaft) are out of their expected correlation — in other words, the cam and crank timing don't line up correctly. The computer compares the crankshaft and camshaft position sensor signals to verify valve timing, which is often controlled by a variable valve timing (VVT) actuator. A correlation error points to mistimed valve events, frequently from oil-flow or VVT issues, a stretched timing chain, or sensor faults. You may notice rough idle, reduced power, poor fuel economy, or a check-engine light, and ignoring it can risk engine damage. Typical repair costs on Audi range from $4,500 to $9,000, depending on the specific model and root cause.
Common Causes of P0019
- •Stretched or worn timing chain (and worn guides/tensioner)
- •Faulty variable valve timing (VVT) actuator/solenoid (Bank 2)
- •Low oil level or dirty/sludged oil restricting VVT flow
- •Faulty camshaft or crankshaft position sensor
- •Clogged VVT oil control valve screen
- •Damaged sensor wiring or connector
- •Jumped/misaligned timing during prior service
P0019 on Audi by Model
Audi Q7(1 issue)
- 2007-2010 Q7 4.2 FSI (BAR) Timing Chain Guide and Tensioner Wear - Rear-of-Engine Chain Drive2007-2010
The 4.2L FSI V8 (BAR) in the first-generation Q7 4L uses a rear-mounted timing chain drive with plastic chain guides and hydraulic tensioners. The guides embrittle and the tensioners lose their ability to take up slack, especially on engines run past their oil-change interval or on short trips where sludge forms. Owners first hear a brief rattle at cold start that grows into a constant rattle or whine, and eventually the chain jumps a tooth and sets cam/crank correlation faults. Because the chain drive is at the back of the engine, the correct repair requires pulling the engine (or engine and transmission) out of the vehicle - which is why this failure so often totals an otherwise good high-mileage Q7.

What does P0019 mean on Audi?▼
P0019 stands for "Crankshaft/Camshaft Position Correlation - Bank 2 Sensor B." This code means the engine computer detected that the crankshaft and camshaft positions on bank 2 (sensor B, typically the exhaust camshaft) are out of their expected correlation — in other words, the cam and crank timing don't line up correctly. The computer compares the crankshaft and camshaft position sensor signals to verify valve timing, which is often controlled by a variable valve timing (VVT) actuator. A correlation error points to mistimed valve events, frequently from oil-flow or VVT issues, a stretched timing chain, or sensor faults. You may notice rough idle, reduced power, poor fuel economy, or a check-engine light, and ignoring it can risk engine damage. On Audi specifically, this code is documented across 1 model.
What causes P0019 on Audi vehicles?▼
Common causes on Audi: Stretched or worn timing chain (and worn guides/tensioner), Faulty variable valve timing (VVT) actuator/solenoid (Bank 2), Low oil level or dirty/sludged oil restricting VVT flow, Faulty camshaft or crankshaft position sensor, Clogged VVT oil control valve screen. Specific causes vary by model and year — see the per-model sections below.
