C4 near side mirror adjustment issue.  Hi everyone, I’m a newbie but decided to post the issue I have with my C4.My C4 is new in November 2017 but we have a problem due to wife’s height!She is around 5ft 5 inches tall and when she is sat in drivers seat she cannot adjust nearside mirror enough to see side of car.Took it to dealer for a “authorised Citroen fix” but issue is worse!Apparently they filed down part of the internal motor mounting to enable the mirror to fold in more to show side of car but all it did was cause mirror to catch the plastic housing!They have ordered another complete mirror unit, but I’m not sure that will work. Works are being done under warranty so no problem having to pay.Dealer seems to think that the C4 was designed as L Hand drive as wipers are the type you would see on those cars as well.Anyone encountered this problem and is there a known fix for it as I’m not sure Citroen have one!Cheers  By JX2566  On Thu Apr 05 2018, 09:34am
