CEL on 2008 Cayenne S

[chucklong]

Gents,

The CEL came on last Friday so I hooked up the Durametric and ran the fault test. The only code to come up was 0021. I reset the fault and it came back on within 60 miles. The car runs perfectly fine in all areas of operation and rpm. I did a little research on this and checked the camshaft deviation while the engine was running, bank 1 read 2.62 CA and bank 2 read .37 CA.

If someone can point me in the right direction on how to accomplish the below maintenance, I would really appreciate it.

Semper Fi

P0021 Adjustment of Inlet Camshaft in relation to Crankshaft, Bank 2 – Signal ImplausiblePossible cause of fault- Dirt in oil circuit- Sealing strips on inlet camshaft adjuster faulty- Oil pressure too low- Mechanical fault in inlet camshaft adjuster- Magnetic hydraulic valve faulty

Try an oil change first and maybe a flush
