[kane1210]

when i have the climate control off , there is still slight airflow through the vents why is this?

Also since having the car ive had to replace both cv boots anyone else had to do this ?

As long as you don't have the CC set to recirculate, then when you turn it off there will still be a trickle of air through the vents when you are driving, as air is forced through the HVAC unit.

If it bothers you, hit the recirc button and direct the airflow to your feet before you switch of the CC.

+1. TBH I've had this happen on other cars, so not a surprise for me.

Forward motion of the car will still force air through the vents.

What specifically was wrong with the boots?

You really don't wanna be using the recirc for anything more than very brief periods.  You can end up getting light-headed due to reducing oxygen content.

Me thinks they 'split' it for you!   CV boots should NEVER split that early!

You saw it with your own eyes?   And you also saw the tel-tale traces of 'further evidence' to support a split CV joint boot?

It's amazing how many cars fail MOT's for split CV boots.

If the garage is short of work it is so easy for them to 'accidentally' catch them with a screwdriver during the test, especially as they get older because they can get weaker.

It's a nice little job for them because the parts cost buttons but they can usually sting you for an hours labour, in which case most people will pay this because it's "only a hundred quid or so" to get the car through it's MOT on the same day and save the hassle of going back.

It is a point that was raised before but having your MOT done by a place which makes it profit from repairing cars is not a good idea. You are better off taking it to a council-run testing station that does not do any repairs.
