What specifically do you mean by the heater was playing up, but now was working again? was it blowing cold constantly despite the engine being up to temperature?
I had an issue with one of ours where the coolant system had got a significant airlock in it, and after I ran the car to temperature with the heater turned up to the max and the system burped a load of air, it started blowing warm air in the car again

Yeah should have been more specific - was constantly cold, absolutely no heat from the vents at all, even on a 3hr journey -
@lynx @BrickMan - 2014 vintage 1.6, that's the first I've learned about a header tank full of silica, sounds ominous - Jesus who thought that would be a good idea! Our local mechanic is good for most things but sounds like it might be time to abandon it in the nearest VAG garage, cheers for the tips!

Random one - the heater in our roomster has been playing up recently, local garage has had a quick look at it when it's been in for service etc. but no dice... recently it's also been a bit sluggish at low revs/speed - didn't ever think the two could be related but end of last week the engine check light came on, shortly followed by the DPF one - it sees mainly 20 mile each way motorway trips most days so not predominantly short journeys.
Gave it a good run at ~3k rpm over the weekend & the lights are still on, however it feels much better at the low end, but also the heater has started working again - wtf? Could it be some sort of sensor problem or is it about to shit itself?
