  • Vacuum system leak Moderate
  • PCM control circuit fault Low

Step-by-Step Diagnostic Procedure

  3. Test runner control solenoid operation with a scan tool

  4. Check for proper vacuum supply to the actuator

Common Fixes by Vehicle

What techs usually find when diagnosing P2006 on specific vehicles — tap your vehicle for the fix and the exact part:

2005-2015 VW/Audi 2.0T FSI/TSI hard DIY

Intake manifold runner is stuck closed -- replace entire intake manifold (runners integrated, not serviceable). VW part 06H133201AS for early applications, 06K133201 for later. Walnut blast intake valves while manifold is off. Budget 6 hours.

Labor: 5-7 hours
2007-2013 Nissan 3.5L VQ35 (Murano, Altima, Maxima) moderate DIY

Clean intake manifold runners of carbon. Nissan VQ35 gets EGR carbon in the runners causing stuck-closed fault. Remove upper intake, clean runners with throttle body cleaner and a brass brush. If actuator motor is dead, replace with OEM Nissan.

Labor: 3 hours
2007-2013 BMW N54 Twin Turbo (335i, 535i) moderate DIY

P2006 on N54 means DISA valve has failed closed OR flap is lodged. Inspect DISA immediately -- if flap is missing, check each cylinder for damage (borescope). Replace DISA with OE Pierburg; don't use refurbished units with repaired flap mechanisms.

Labor: 2 hours

Frequently Asked Questions

What does P2006 mean?

P2006 indicates the intake manifold runner flaps on Bank 1 are stuck closed, restricting airflow at higher RPMs and reducing top-end engine power.

Can I drive with a P2006 code?

Yes, short-distance driving is safe. You will notice reduced power at higher RPMs, but there is no immediate danger to the engine.

How much does it cost to fix P2006?

Repair costs are typically $200 to $600. Cleaning carbon from the runners is cheaper than replacing the entire runner control unit.
