Re: Alfa 146 1.6TS (1997) Probs!!
the speedo always sits at 10mph, it recalibrates itself there apparently.
145s are pretty noisy, sound insulation is quite poor compared to more modern cars and wind noise especially from the door seals is very poor, sop much so later cars had a revised door seal. Mine gets much noisier at 75 from the doors. Also the gearing is low compared to some cars which is why it does not need a 5 mile run to hit its top speed.
BTW, no idea about the lighter, I would suspect the design is a bit different and the socket is deeper on the Alfa so the contacts do not reach, my Saab was similar. You may have to get behind the console and wire an alternative arrangement in.
