Thermostat replaced

Car gave a fault message, engine not warming up fast enough...

Never noticed anything from the meter, weather is cold for the last 3 or so months with temps mostly around 32 degree.

Last Friday the code was read from the car. After that I payed a bit more attention to the meter and I noticed that when driving slower (...) the needle was just before mid indicator, not more than one mm. When driving a bit more spirited the needle was exactly in the middle.

After replacing the thermostat it showed that a small "bearing ball" thingy in the thermostat was missing..

I hate these 'idiot gauges' most manufacturers saddle us with. The temperature dials on most cars pretty much have three positions. Cold, Ok, and Hot, with a fairly huge temperature range reading OK (meaning pegged to the center of the gauge). Apparently keeps people from obsessing about it and making unnecessary service calls.

And where did that little ball bearing go? On its way to the water pump impellar? (or worse?)
I hope not!

Interesting, my check engine light came on yesterday. After a night in the service department, they found a faulty thermostat. They replaced it, lubed my clutch pedal, and installed my cup holder.

It was sitting in a corner of the thermostat housing.

I never received any messages on the dash btw.

Re: Thermostat replaced (Johann)

So the fault was detected when you read out the ECU, and not the dash?

Yes. Last friday the car was in for a service and to fit the iPD sway bars. This is when they saw the fault code and ordered the parts needed.
