DTC/P0019

P0019: Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor B)

Quick Answer

High SeverityNot safe to driveIgnition

P0019 means the crankshaft and the exhaust camshaft on bank 2 are not in the correct rotational relationship. The code only appears on V-engines (V6, V8, V10, V12) because bank 2 is the side that does not house cylinder 1. Common causes include a stretched timing chain, a failed exhaust VVT solenoid on bank 2, a worn camshaft phaser, or oil flow problems.

Estimated repair costFrom €60 to €6000+, varies by vehicle

What does P0019 mean?

P0019 is a ignition-related diagnostic trouble code classified as high severity. When your vehicle's ECU detects this condition, it stores P0019 and illuminates the check engine light.

What are the symptoms of P0019?

If your vehicle has triggered P0019, you may notice one or more of these symptoms:

Check engine light illuminated
Loud rattle from the front of the engine at cold start
Rough idle and possible misfires on bank 2
Hard starting, particularly when warm
Noticeable loss of power and hesitation
Increased fuel consumption

What causes P0019?

Here are the most common causes of P0019, ranked by how likely they are to be the culprit:

highStretched timing chain (chronic on Audi 3.0 TFSI, VW 3.0 TDI, Mercedes M276)

highFailed bank 2 exhaust VVT solenoid

mediumLow or degraded engine oil restricting VVT operation

mediumWorn timing chain tensioner on bank 2

lowFailed bank 2 exhaust camshaft phaser

lowBank 2 exhaust camshaft position sensor fault

Is it safe to drive with P0019?

No - address this immediately. Drive only short distances to reach a workshop. P0019 indicates the exhaust camshaft on bank 2 is out of correlation with the crankshaft. On an interference V-engine, continued driving risks the chain skipping teeth and bending valves, which on a V6 or V8 means a 5000 EUR or greater engine rebuild.

How do you diagnose P0019?

Follow these steps to pinpoint the root cause of P0019:

Check engine oil level and condition. V-engines share oil between banks, so low pressure or contamination affects both. Use only the manufacturer-specified viscosity and approval (BMW LL-04, VW 504.00/507.00, MB 229.5/229.51)
Listen for cold-start rattle from the front of the engine. On V6 and V8, the rattle may originate from one bank specifically. A stethoscope helps localise it
Use a scan tool to monitor live cam phasing data on bank 2 exhaust. Compare actual versus commanded angle. Deviations over 5 to 10 degrees confirm mechanical timing fault
Test the bank 2 exhaust VVT solenoid. Resistance typically 6 to 13 ohms. Inspect the mesh screen for sludge debris. A clogged screen is a common quick fix
If the solenoid and oil are good, suspect timing chain stretch or guide wear on bank 2. A workshop will need to remove the bank 2 valve cover or front cover for inspection

How much does P0019 cost to fix?

Repair costs for P0019 vary depending on the root cause and your vehicle. Here are typical estimates:

Repair	Parts Cost	Labor Cost	Total Estimate	DIY Difficulty
Oil change with correct spec oil	€40–€100	€20–€50	€60–€150	Easy
Replace bank 2 exhaust VVT solenoid	€80–€300	€60–€200	€140–€500	Moderate
Replace timing chain kit on V-engine	€800–€3000	€800–€3000	€1600–€6000	Professional

Common questions about P0019

Why does P0019 only appear on V-engines?

Bank 2 refers to the side of the engine that does not contain cylinder 1. Inline engines have only one bank, so P0018 and P0019 cannot appear on them. P0019 specifically requires a bank 2 exhaust camshaft sensor, which means the engine is at minimum a V6 or V8.

Is P0019 worse than P0017?

P0017 and P0019 are essentially the same fault on different banks. The mechanical severity is identical. However, P0019 is usually more expensive to repair because it implies a V-engine, where timing chain access requires more disassembly. On engines like the Audi 3.0 TFSI, the supercharger and intake manifold must come off.

Can I just replace the bank 2 VVT solenoid first?

Yes, it is the cheapest first step at 80 to 300 EUR for the solenoid plus 60 to 200 EUR labour. If the solenoid fixes the code, great. If P0019 returns within a few weeks, you are dealing with a stretched chain and the solenoid replacement was diagnostic data, not wasted money. Always change oil at the same time.

How long does a timing chain job take on a V6?

Plan for two to three full days at a workshop. On the Audi 3.0 TFSI, removing the supercharger, intake, and front engine accessories is half a day. The chain work itself is another half day. Setting the chains, reassembly, and test drive is another full day. Labour totals 15 to 25 hours depending on the engine.

P0016 Code: Camshaft Position Correlation (Bank 1 Sensor A)

P0016 means the crankshaft and camshaft are out of sync. Usually a timing chain stretch, VVT solenoid, or oil issue. This can be expensive if ignored. Here is how to diagnose it and what to expect.
