Hi all,
I have an Audi A3 2.0 TFSI Quattro 2004 with 111,000 miles on the clock - I have had it fully serviced this week and the MOT passed 2 months ago with no faults or advisories.
I've noticed the engine when driving takes forever to heat up and won’t hit 90 degrees centigrade, but if I let the car sit and idle it will reach 90c.
When driving from 90c onto a motorway the gauge shows the temperature to drop down to quarter, so roughly about 70c. I cannot hear the engine fans running when this is happening.
This week I had both the thermostat and the coolant temperature sensor replaced. Prior to the thermostat being replaced the engine fans would come on straight away on ignition and at random intervals - this does not happen since having them replaced. Coolant levels are what they should be as well. The only error code returned was stating the original coolant temperature sensor was faulty.
Note that before having the thermostat changed, the car would never reach 90c at idle, it now does from the replacement
When I turn on the car heating to the max, the air feels lukewarm at best even when the engine says its 90c - When I turn the heating on though, I can see the temperature gauge start to drop until I turn the heating back off again.
The car runs fine and never over heats.
Any help is fully appreciated.
