Well these r the problems :-
1) rain sensor wipers(on intermiting)
on my mk2 172 i think the rain sensor wipers r crap when on intermiting it takes ages for them 2 come on i always have 2 keep flicking the wiper arm up and down for them 2 work.
And the rear headrests, Y did renault change the style from the mk1 as they r down over the seats and stick in ya back and they look daft pushed up, so ive changed mine and fitted the same colour leather Megane rear headrests so they r just like the mk1 now.
When i had my mk1 172 it was better car i.e less things go wrong
