If it is an early C2 model, it might be worth trying to clean the idle control valve.

Suggestion

Cleaning the throttle body might help, but this normally causes an erratic idle, rather than a consistent slow idle.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

hi can someone help the idle seems a bit slow i wondered can it be adjusted it looks to be ticking over about 550 rpm(unless im reading it wrong) also fluctuating by about 20 revs is this normal?any help on this subject would be great. many thanks. :?:

POST 2Original post

:welcome: No it can't be adjusted. The tickover should be around 700 rpm +/- 20rpm. If it is an early C2 model, it might be worth trying to clean the idle control valve.

POST 3 / ORIGINAL POSTEROriginal post

its a 2001 c4 should i clean the idle valve? thanks

POST 4Original post

Being a C4 it will have electronic throttle, and these don't have an idle control valve. Only the early C2s with mechanical throttle have them. Cleaning the throttle body might help, but this normally causes an erratic idle, rather than a consistent slow idle. If it is idling at 550rpm then something is a bit amiss. It might be worth getting a diagnostic check done.
