The 000022 Vcds trouble code often indicates a correlation issue between the crankshaft and camshaft positions. While a VCDS scan can detect this discrepancy, signified by a P0016 DTC, it doesn’t pinpoint the root cause. The engine control module (ECM) only registers that the camshaft isn’t in its expected position relative to the crankshaft, not why.
One potential cause is insufficient oil pressure to the camshaft adjusters. Diagnosing this can be challenging because oil pressure is typically measured at the engine’s bottom end, not at the critical point near the camshafts. Unfortunately, no specific test exists for oil pressure at the cam adjusters.
While you can use VCDS to perform an Output Test on the N205 and N318 cam adjuster valves, hearing the “click” doesn’t guarantee proper functionality. Internal sludge or debris might restrict valve opening, even if they respond to the test. Ohm testing the valves can provide additional insights into their electrical health.
Physically swapping the N205 and N318 valves requires removing the timing chain cover to access their securing screws, a more involved procedure. However, swapping the crankshaft position sensors (G40 and G163) might be a simpler diagnostic step, as they often share the same part number and are typically held by a single screw.
Including your vehicle identification number (VIN) when seeking assistance is beneficial for accurate diagnostics. It helps technicians understand your vehicle’s specific configuration and potential issues related to the 000022 VCDS code. Rest assured, providing your VIN doesn’t pose a security risk.
