I am new to the forum.... So hello everybody
have recently got a 2002 a4 avant 1.9tdi got it cheap as was in need of a turbo, turbo fitted all fine and runs perfect but I noticed it was not reaching correct running temp (needle was in 50) so I got a new thermostat and temp sensor for good measure last night put the new thermostat in and sensor and run it up to temp, pulled the pipe of to expose the hole by he bulk head to allow for air to come through still the bottom radiator hose was http cold after 45 mins have run it up the road etc so possibly a faulty new thermostat?
any ideas appreciated
thanks in advance
