The 159 was in with a failed heater (only blowing cold air) a couple of weeks before the end of the 2 year manufacturer's warranty. As it was going to cost more than £1k to fix (it was £700 just for the parts
- needed a new heater box - plus 10 hours labour so probably nearer £2k in the end), they had to wait for authorisation from ARUK which added about 24 hours to the time off the road.
Now the Sat-Nav has gone on the blink - yes, I know it's not the best and to be honest I hardly ever need to use it, but if it's there then it should work - so in it has to go again. Only difference is that now it's into the 3rd year, it has to be inspected by someone from the warranty company. I took the car to the dealer at the arranged time yesterday, the guy was there waiting, took the car straight into the workshop, tried a new disc, made no difference (still thinks I'm driving around in a field somewhere in North Wales
) so he authorised a replacement unit there and then (at a cost of £2.5k
- thank God for warranties!)
Got a call from the dealer today to say that the new unit is on its way, should be here Tuesday and I just need to pop in for 15 minutes or so to get it fitted.
So from what I've experienced, if anything the 3rd year approval process is quicker.
