temp sender unit?

2 posts in this topic

Well since the last post I've had the thermostat changed on my 1997 Audi A4 TDI and it still reads hot from cold IYSWIM. Do these read hot when the temp sender unit is knackered as a fail safe? Its worrying the life out of me smashfreakB.gif

Can't you remove it and bench test it? or does that require a full coolant drain?
