Remember a few weeks back I posted a query about the PRNDS part of the display flashing on the DIS? Spoke to Audi at the time, they didnt know what it was and advised bringing it in if it did it again. It did it on thursday, phoned them, took the car straight in - they pulled an engineer off of lunch, plugged it in, and within a couple of mins had determined that a sensor in the gearbox has failed. No mechanical fault, all still drives beautifully.. However - wouldnt let me take the car on, as this needs sorting under warranty, bit of a problem as I was booked on a ferry to france a few hours later and they had no courtesy car.. all sorted within minutes though, they contacted audi central and organised a hire car, approved to take abroad, for as long as i needed it, and I was sat in it within 40 mins.. Audi even loaned me a nokia charger as I normally have the in car kit.. So, Service from Southampton Audi absolutely top notch on this.. however, the implication of this blasted sensor failure turns out to be a whole gearbox out job, replacement of the Gearbox electronic control unit, and a 5 day wait before the parts even arrive from audi.. Am very glad this is under warranty! Have to say I might think twice before purchasing a second-hand car with a multitronic, despite how much I like the box, if a simple sensor can cause this much work.. Though presumably a DSG box is similarly equipped with internal electronics and sensors! Maybe just unlucky..
