Left Pulling is quite normal problem for fiat Punto and Linea models...I have taken my car ...couple of time but they couldn't...FIAT service is able to fix it temporarily but not permanently. After googling on this...I go to know tat...this complaint is a kind of virus to FIAT cars across the globe. The only solution is to...get the DISC's chaged....I have discussed this with the FIAT engineer who recently visited the Exclusive fiat service dealer here in hyd.... He proposed the dealer to get my DISC's chaged...waiting for an appointment!!!!
