Cale i ja sklopili auto lagano i polako bez ikakvih problema. Jeste da je bilo malo nejasnoce oko ulkapanja ali nista nije neresivo. Svima se zahvaljujem na korisnim konsultacijama. Sad mi preostaje samo da vidim da nabavim program i kablove za dijagnostiku, cisto daima i sve radim sam na auto. :)

Sto se tice popravke lock na temu auto sklopnje i vozi se :D
