CTT code 0012

[Magnum08]

Recently purchased an 08 Cayenne turbo with 50K miles and just got a check engine light. Durametric code is 0012---value below lower limit value.

Anything I could check for first?

Any help would be appreciated.

P0012/1349:

Possible fault cause:

- Solenoid hydraulic valve camshaft adjustment faulty

- Allocation of camshaft to inlet camshaft incorrect

- Dirt in system

- Solenoid hydraulic valve mechanically blocked

I suggest you reset it and see if it comes back....

[Magnum08]

Thanks for the quick reply Loren. I have reset it and it comes on pretty frequent.

Will checking for boost leaks help? What steps should I take first?

[Loren]

If it is a P0012 then it is camshaft related not boost.

When did you last change your oil? It could be as simple as small particles of debris causing the camshaft actuator to hang up.

I changed it last 1200 miles ago but it's my 2nd interval changing the oil. I too don't think it has anything to do with boos leak but that's what the shop thought.

I might just have to take it to the experienced Indy since dealer doesn't want to touch it. Modified and ecu upgrade.

What rough estimate in labor am I looking at? Parts and labor?

[Loren]

Does the car run ok?

[Magnum08]

Yes comparing it to when the code is cleared not much difference.

They may or may not be need for work.

If you want to feel safe you could commit to 1 hour labor to have the dealer/shop put it on a PIWIS tester and see what else pops up - if anything.
