Common Fixes by Vehicle

What techs usually find when diagnosing P2008 on specific vehicles — tap your vehicle for the fix and the exact part:

2005-2014 VW Jetta/Passat 2.5L I5 easy DIY

Check IMRC actuator connector at driver side of intake. VW 2.5L harness chafes against valve cover bolts causing open-circuit fault. Repair wiring with solder + shrink. If wiring is good, replace actuator with OEM VW.

Frequently Asked Questions

What does P2008 mean?

P2008 indicates an open circuit in the intake manifold runner control solenoid circuit on Bank 1, meaning the PCM cannot control the runner flaps due to an electrical fault.

Can I drive with a P2008 code?

You can drive short distances, but engine performance will be reduced. The runner flaps will default to one position without electrical control.

How much does it cost to fix P2008?

Repairs typically range from $100 to $400. A wiring repair is inexpensive, while a solenoid replacement costs more.
