Hi,
More trouble with temp. When the car is in IGNITION, not engine on, temp is unstable in dash. How can I fix this? Have already changed temp-sensor.

Regards

Sounds like Battery problems to me?

Has the ECU software been updated? Commonly noted issue in the GP section which a software upgrade normally resolved

Hi, can the ECU lose software update after battery change? /M

Ahh, now error P1684. It won't go away, battery?

P1684 = Fault during self learning of throttled body (low battery or plausibility)

Could be a battery problem but I would expect that to give other problems, not only the temperature guage.

New battery

Hi,
I have an idea, if battery is broken the light will light less when fan kicks in. Could generator be broken? How can I test it?
What type of model/generator will fit 1.6 dyn 3door with AC?

Throttle was jamming, half open. Almost stuck when it tries to open it by hand. Took the throttle appart and oiled it. Sprint is ok. The car more awake now. I have used FiatECUscan 3.6.2 and tested coil. Seemes ok!? Fan is ok. Injectors are ticking with the test. B1684/P1687/P1220 are gone now. The car is still sometimes unsteady. I hade switch coil one by one with another coil and still little unsteady.
