184ps FR TDI Regen Frequency
- Thread starter Dt-spd
- Start date
Something like that.
2000 to 2400 rpm at a steady speed over 40mph until the dpf light goes out
And yes - they say 15 mins should clear it.
2200RPM would be around 70MPH, I suppose. No idea if you're right or wrong about increased fueling but I haven't seen that comment before. It strikes me that if that does happens at 2200RPM and that co-incides with 70MPH then it's an odd speed to choose to deliberately impact MPG.
Generic DPF advice is keep is somehwere between 1750 and 2500 at around 50-60MPH (which may mean using a lower gear than top) but the point on VWs with EA288 is even in lower gears the DPF doesn't heat up more. It's all about the load. I guess it would get warm if you were pulling a large caravan!

Ah, OK - that makes sense if you've got to the stage where the light is on and the owner is doing a "Regeneration Drive". It's the lack of passive regen which is bugging me.

Mine used to do quite a lot of active regens (would notice higher idle speed or fans running when I turned off the engine) but today is the first time in over 3k miles that I've noticed it doing it. Interesting to see the comment saying it will do it every 465 miles as I haven't noticed this on mine. Maybe it's doing it whilst I'm on the motorway and that's why I don't notice
Logged some data at a constant 2200rpm on the motorway ( about 120kph ) and DPF outlet temp doesnt go above 310degC, so not enough for a reliable passive regen. Engine operating mode doesn't change so it doesn't change fuelling to improve a passive regen. Looks like most users will have a active soot based regen triggered when soot gets to about 18g ( 250-300 miles ) and if that doesn't happen then at 465 miles it does a distance based regen. Which all makes good engineering sense but not best for oil dilution or fuel economy.
The general advice about driving 1750rpm - 2500rpm is just to make sure the driver is operating the engine in the range where a active regen is most efficient at generating heat. It needs a defined range as its not easy to tell a customer they need to be driving harder because they then start revving it hard which doesn't make as much heat and makes more soot.

Is this engine as bad as the old PD167?, as we are looking at getting the 184 FR but am worried about limp home mode etc...
I ran a 2007 Golf with the pd167 engine and the 184 is much better. Better power delivery and overall much nicer to live with. The 184 does sound a bit agricultural at times but modern injection systems and dpf are a step change from the pd setup.

So I shouldn't see the dreaded limp home a lot?, I ended up having the dpf removed on our PD as it was happening every two weeks the dpf would need a regen
want my honest oppinion..
After running a 184tdi fr for last 7months its only did a full clean about twice
that is ive noticed it doing its regen when pulling up from a run outside my house so i left it running.
25mins the last time it did it....
Thats on a 9,800 mile engine..
it only had 4500miles on when i bought it in march.
As for it sounding Agricultural its far from it...
It doesnt even sound like a Diesel this engine...
I prefer the Tractor sound of the Mk1 FR 1.9PD 150hp engine anyday over this.
Its like a quiet 1.6petrol engine & it revs like one if you want it too.
But loads more torque than any 1.6petrol or 2.0petrol easily.

This engine EA288 as designed to work with a DPF where as the old PD motor was adapted to wok with one.
Completely different animals.
My worst case month for my 184TDi was 2miles to work and 2 miles home each day with only a couple of slightly longer ( 10miles ) trips at the weekends.
Still never saw the DPF light on.
