I think an average is about 500mls.

Hi you want to keep it above 2000 rpm, so can do at slower speed in a lower gear. An average time seems to be 15 minutes dependant on temp as well. Normally each DPF regen is around the 500 mile mark. I have had one take about 6 minutes and another take closer to 30.Edited by: HoneyMonster

Can someone tell me if a light comes on on the
Dash board when a Regen takes place?
I think that mine has just done one but only signs were
The mpg dropped from 32ish to 26ish mpg and the fan
Was blowing when I came to turn off engine ???
Is this a Regen ? Passive Regen? Or just coincidence ??

Sounds like a regen that you interrupted, chances are you will get another attempt on your next run, plenty of info on DPF's on the forum, will keep you busy for hours reading it all.

I took it for a good blow out run straight after I herd the fan
Reset the mpg meter a few times after about 10 mins
It started creeping back up in the 30's as normal
But my question was does it have a light for Regen ?

No Shaun no light for a regen in action but there is one comes on if to many regens are interupted and then you must complete the regen cycle.

I have only had my 2013 Antara a few weeks now and driven 1300 miles of the 7000 miles on the clock. I have not noticed a regen in this time but at the weekend was returning home from the airport (90 miles) visiting my daughter who lives 3 miles from home on the way, switched off the engine and everything was as normal. However after an hour drove the final 3 miles home and when I switched off the engine the fan came on. I decided to drive on for a short while (15mins) in a lower gear/high revs but this did'nt stop it. I attempted it again the following day driving for around 15mins in a lower gear/high revs but again it did'nt stop it. During this time there has been a drop in mpg. I have today driven for approx 20 mins lower gear/high revs again and mpg suddenly became noticeably better and when I switched the engine off no fan! Reading dpf threads it was clearly interruption of the regen cycle. However I now have a couple of concerns and wonder if someone can advise me.
1. Do the 2/3 attempts cumulatively add up to one complete regen cycle.....or was it the final attempt that cleared it?
2. Has a full regen been completed based on the above?
Sorry its a bit long winded but would welcome any comments.

Hi, yes they add up to 1 successful regen. I tend to drive on the motorway in 5th and keep the revs at 2000. It keeps the engine under load as well as hot.

I recently had an interrupted regen on the way to work. When finished work I drove up n down the motorway for about 15 mins - sorted.

Chrisg I kept it in low gear and over 2000 revs but it took 3 short attempts to clear. Maybe next time I will run it longer and hopefully it will clear in one attempt... my mind is now at rest! Many thanks

It's not unusual for a regen to need 20 miles to complete.

I've never found it necessary to drive in low gear/high revs for a regen to complete normally. I just drive as I normally do and the regen will complete after 15 to 20 miles.

On the odd occasion when I have had an interrupted regen, the regen has usually restarted within about a mile or so when the engine gets back up to temperature, and completed as normal. The combined mileage before and after the pause in the regen was more or less the same as if it had completed in a single session.

No matter what I have done, my regens happen at an average of 521 miles.

Just had the regen light come on for the first time after 8000+ miles. Drove onto the M5, drove 6 miles to the M6 just got off the slip road onto the M6and off went the light, everything back to normal.

I tend to hold it in a lower gear,because I only drive at 50mph on the motorway,so I keep it in a lower gear to keep the revs up when having a regen.
