I have noticed my Audi A2 is idling rough and making strange noises. What steps should I take to diagnose and fix this issue?
ReplyStart by checking your spark plugs and ignition coils. If they are worn or damaged, replacing them can improve your idle. Also, clean your throttle body and ensure your air filter is clean.
A common cause of rough idle in Audi A2s is a faulty mass air flow sensor. This can be replaced fairly easily with a new OEM part. Another possibility is a vacuum leak, so check all hoses and connections.
It's always a good idea to do a scan with a diagnostic tool to see if any trouble codes are present. This can point you in the right direction for the specific issue causing your rough idle.
