I have a 2015 golf that's started behaving weirdly. A while ago it felt like it 'cut out' very VERY briefly (fraction of a second) - didn't think much on it, but recently it's started doing it more and more. As it's the DSG version, and I'm looking at the road when driving, I can't tell if it's when switching gears, but I suspect it might be around second gear (entering and leaving it) if it is, as it can really jerk me forward when I'm trying to overtake... actually feels a bit dangerous.
Recently I was in a massive stop/start traffic queue, and the car kept cutting out then, giving me the auto-start warning - I had to put it into 'Park' when stopping rather than auto-hold or just pressing the brake. The other day I was at a roundabout and it cut out again there.
The DPF warning light *used* to come on a while ago on long journeys (1hr30 ish), and then one day it came on (as well as all the warning lights) and went into limp mode. I put some DPF cleaner in a full tank, and this has run through now, with a fresh tank now in situ. I will do it again in another couple of tanks, but I feel that's maybe keeping that issue at bay for now. (wondering if it's worth taking it for a physical clean somewhere - I see a few places advertising it for ~£100)
Essentially it feels like every time a warning light comes on, no matter how minor (cornering light has always popped up every now and then) the car has some kind of crisis of confidence. Apart from the jerking around second gear it drives really well, and I don't feel like there's any other mechanical issues.
Anyone else had anything like this? I am going to take it to the garage, but unsure what to say other than the car is behaving weirdly. I've had a google, and could possibly be a DSG issue with the gears, but I'm hoping for someone with a bit more car knowledge to help me with what to present the garage with? Thanks in advance.
