DPF came standard with the MY11 Facelift, but it was an option I think prior to this, to be honest in 32k it hasn't been a problem.

It's heat...not revs or speed.

Revs whilst in neutral don't give heat off like moderate revs whilst travelling at a moderate speed. Your best bet is to get on a motorway, and if you're just doing one junction to clear it out, use 5th gear.

All the people that think they're ok as they do lots of motorway driving aren't immune though, one day after 60k miles ish you'll need a new DPF. Mine: 2012 Golf GTI Edition 35

I’v got the DFP full on the display after running without diesel due to faulty reader. When i took it to the frontier (LR Agent in Sri Lanka) said either you can spend Rs 18000 to clean it or just take a ride in the Sothern Expressway. and before i was going to the LR agent there was a big white smoke for 1 min so i knew it's the DPF. So agent reset the error code and i hit the freeway on 3rd gear 3000 RPM 80km/h (50/mph) for 20min to down south and returned home with on 120km/h and all ok so far no errors runs smooth.
