    AAARGH!!!! 2001 S3 temp issues and more!!!

    Any thoughts on the following symptoms for a 2001 S3
    • Car struggles up to get to and does not maintain a normal running temperature
    • ECU light on
    • Below average MPG 24ish careful driving used to get more
    • The air con does not know what temperate it is, I.E whatever temp I set it at it blows about the same and the air does not get hot.
    Any suggestions as to what will be causing these issues and which I should tackle first?

    Many thanks for the help!!!!!

    Having been through a similar experience, point 1 will be down to the thermostat, resulting in point 4, and 2 and 3 could be the CTS incorrectly reading the coolant temperature and therefore running slightly rich. Thermostat is about 24 from Audi, the CTS around 8-9 from any parts retailer.

    Note - I had a "genuine" Audi thermostat fitted by a dealer, didn't resolve the problem. Collected and fitted a "genuine" Audi thermostat myself today, problem resolved. I did the CTS too, purely because I had my tools out and it's only a 5 minute job.

    As said, change the thermostat first then see how things go
