Rev's hunting at idle

ac427 · 23-09-2019, 01:12 PM

The rev fluctuate at idle like someone is gently pressing the throttle.

Does this sound like a vanos solenoid issue?

I'll check for codes but i don't think there are any.

I replaced the Vanos solenoid and gasket but the hunting issue still remains.

Has anyone experienced this?

Turn the air con off and see if it still happens

Had these symptoms earlier this year and it was the front TPS.

Did an error for the TPS sensor show up in diagnostics?
