While the weather has been cold iv noticed my car hasnt been getting hot, changed the coolant and such but made no difference so I thought I would change my stat. Iv located what looks like the housing and removed it but no stat inside. The part iv removed is the plastic housing next to the sai on the engine block. Iv picked one up from euro carparts and they have given me a thermostat but my question is, is my stat that plastic unit, and is it map controlled or am i looking in the wroung place?? Car is a 2000 s3 apy cheers
