In the autumn of 2001, the renewed 4300 series models corresponded to the earlier 4200 series models. In the larger models, the most significant change was the addition of a turbocharger to the 4370, which increased torque. The torque characteristics of the 4355 had also improved. The cabin had updated controls and upholstery, and the noise level had slightly decreased. The exhaust pipe was now located in the pillar.

In 2002, the 4365 was introduced, featuring an intercooled four-cylinder turbo (106 hp). Otherwise, it was completely identical to the 4355 and replaced the 4360 model in the lineup at the same time when MF's representation was transferred to Kesko in the summer of 2002.

MF's production in England ended at the end of 2002. The Peria was never manufactured in France; instead, the stocks made in England were used up during 2003, after which the 4300 series was replaced by the 5400 series.
