Had the light come on last weekend on mine, only had the car a month and was aware it could have been on longlife servicing in the past.. Turned the car off straight away (I was in town centre so was lucky) checked oil which was fine. Drove half a mile to my house and scanned car which showed no faults.
Drove 15 miles to my work the next day and had the sump and pickup off and cleaned out and did the follower at the same time. Pickup wasn't as bad as I've seen them, but managed to get it like new and sump had a layer of sludge in the bottom which wasn't pleasant either. Looks like it's just luck whether you get away with it
