63 Plate Freelander 2 DPF Warning Light

Cobby44 · Aug 29, 2022

Afternoon,

This morning on my way into work I was welcomed with the attach warning light on my dash.
I have a FL2 63 Plate 2.2 SD4 with 112,000 miles on the clock purchased in March.

I’ve had no issues up until now (if this is an issue).

Can anyone shine any light on this at all? Do I need to get it booked into a garage? Diagnostic check?

Thanks in advance.

It says see the handbook, so what does the handbook tell you to do?

From memory the dealer will force a regeneration, but just because the pressure sensors say the DPF is full, doesn't mean it is. A split in the downstream exhaust pressure sensor pipe will often flag a false DPF full issue, as it's not registering the correct downstream pressure.

Probably needs an Italian tune-up down the motorway.

Take it for a drive at 50mph constant or above. When hot it will trigger a dpf regeneration if one is needed. I would assume so as thats what the message is tellng you, unless something is wrong and triggering the message by default.

Regeneration occurrs at speeds of 37 to 70mph. A full regen can complete in 9 minutes but should complete in 20, if the system is working ok. No need to drive it like you stole it.

So, you might have to burn about 1/2 a gallon of fuel to regen the DPF.

And this is good for the environment.

In typical use the dpf should regen when needed without fuss. Dunt need a full regen. It's happy with a partual regen. It uses a very small amount of extra fuel in the process. The benefit is to reduce the particle output from the exhaust. Sometimes yer may need to go for a drive but thats no hardship when its a Freelander.

DPF warnings generally happen when car is only used for local trips. My son used to get it regularly, but since his girlfriend moved 50 miles away, he no longer gets the issues as it regen's itself on the M40.

It simply regens when the vehicle is at higher seeds, the assumption being that the vehicle is then out of a dense urban area.
Technically the same crap comes out the exhaust, it just saves it up until the vehicle is away from a densely populated area, using the above assumption.

They burn oft the stored soot at a higher temp so there's less particle output. My exhaust end pipe is surprisingly clean when compared to non pdf FL2's. Mines just done it's 60th full regen.
