My 1.4 is 70kw from November 2006 so it was part of the final production series. All electrics are normal as far as I know. Has someone been altering your electrics eg previous owner?

Thank you for your reply. These electronic diferences aren´t homemade by previous owner, but maded in last production year I think, maybe it is only in 1.4 66kW. I had 1.2 16V, 1.9 JTD and 2.4 Abarth before and everything is correspondig to schematics on these cars. For example, in your 1.4 70kw, from where do you hear clicking sound of direction indicators ? Every Stilo that I had, produced this sound from Body computer under dashboard (by relay). This 1.4 66kW Stilo make clicking sound from instrument cluster (by speaker). When I replace them with another one older instrument cluster, direction indicators only flash, but without clicking sound.

It's a mystery to me, although I think the 66kw version of the 1.4 was not available in the UK, only the 70kw version.

Do you have a Fiat agent near you in CZ? They may have some information.
