Got it back from the garage today. Sorted my rattle exhaust (hopefully it will stay quiet now), sorted airbag warning light and hopefully sorted my erratic idle. Been gone since thursday only set me back £120 so happy with that.
Since being back iv fitted aero wipers to the front, that seems to have sorted my drivers side wiper scraping up the window rather than clearing it.
Also got my sharan badge, sanded it down just started to paint it.
