So I've only had my 2012 2.0 TDI Sportback since end of January this year, and the wife and I went out for a motorway run today to try to get this DPF regeneration light thingy to come on, but there was no sign of it at any point during 2 separate runs at a constant speed of 59mph, in 4th gear, at a fairly constant 2,500rpm. First run was 43 mins and the second was 25 mins.

Not entirely sure what's going on here. For the last 3-4 weeks or so, I've been doing very short journeys of only a couple of miles, twice a day to take care of my elderly Mum. There's not been any time for a longer drive and so I thought it would be a good idea to give the car a better run to help clean the DPF, but nowt happened.

To make things worse, when we got back home and parked up at the house, the sun was hitting the instrument panel, and it was easy to see where all of the warning lights were located in the binacles, even though none were lit up other than the parking brake. There was no sign of a DPF regeneration light.

From what I understand, I thought it was located on the rev counter, in the area that the needle covers at 2,000rpm. Is that correct?

Also, I do have a DPF don't I? The car's a 2012. I thought all diesels sold in the UK were fitted with one from 2009 onwards.

Your car does not have a DPF regeneration light, they don't work like that. It'll automatically do an active regen when it feels like it by injecting additional fuel into the exhaust to burn everything off. It'll do this every 200-300 miles without your intervention, you do not need to do anything, and you do not need to drive it in any particular way.
It'll do it whether you're on the highway at 80mph or in town at 20mph. The only thing that'll give it away that the regen is happening is that an automatic will downshift a bit more aggressively, the throttle will be more sensitive, and the exhaust will be louder.

That's not the answer I was expecting I have to say, but the outcome couldn't really be any better. That's absolutely awesome! Thank you very much for your explanation, it's much appreciated.

The car's a 6 speed manual by the way.

Thanks bud 👍
