Would like a "DPF - is regenerating" - light in th

Hi,

while the DPF is behaving fine and I couldn´t tell there was one (but it´s a ´12MY so I can be sure) and I never got the orange or even red warning light, I would be quite fond of a warning light that tells me that the ECU is doing a regerenation right yet.
Point is, the 2.2 is due to the second service at 20.000km. And the oil level is a few but noticeable mm´s above the max. mark on the dipstick. So there must be considerable amount of Diesel in the engine oil. [Don´t like].

The current software version was flashed to the ECU 5.000km ago. Maybe that it helps in this matter.

But I understand that the regeneration takes place periodically. And if it couldn´t be completed, because e.g. the engine was stopped, it will start again at the next opportunity. So .. if I knew that the vehicle regenerates I could continue driving or switch to a route which suits the regeneration better. And thus limitig the contamination of the engine oil in the end.

I think the manufacturer preferred to let the driver unaware of anything that has to do with a DPF. But I would like to know. We have to take what we get, not?

Regen is every 400 miles for me and operates at 890 degrees .

I thinks that is what the workshop manual tells me too.
But in real conditions it could happen that at mile 400 the regeneration starts but cannot be completed, because you shut off the engine at mile 403. Next day you go shopping, once the engine is warm enough and you´re driving fast enough it starts again. Before it´s completed you arrived and shut the engine off again. On the way home same thing happens.
So there are 2-3 attemps and then one completed regeneration. And the more regen the more diesel in the engine oil.

I´d like any sign of "recognition" that the vehicle just tries to regen,

Can soneone explain why the regen process might add diesel to the oil? Thanks,

Regeneration means that the exhaust gas temperatures shall be raised. This because with normal driving the exhaust gas isn´t necessarily hot enough to burn the filtred particles and thus not allways passively clean the filter.
To do so there is additional Diesel injected after the "main bang" in the cylinder already has taken place. Kind of "afterburner". IIRC the fuel consumption raises to twice the usual amount in this condition. It´s only small amount of Diesel that is washed away from the cylinder walls by the piston rings and then finds it´s way into the oil sump. But one adds to the other ...

The Dealer just changed the oil of my Dender today. Oil level is now right in the middle of the "XXXXX" mark on the dipstick. Yesterday it has been, say, 2-3mm above the max-level-mark. I don´t know how much the difference between min. to max. means. If it is 1litre then I guess there was 3/4l Diesel in the oil = 10%

Same here, though I don't have a DPF in the Defender but have one in the Freelander, but no light their either.
Used to have some issues with which could have been prevented if I knew it did not regenerate often enough.
Luckely solved since then.

OK, I am not a mechanic but can follow the principle behind the regen programme. Well sort of.

OK can understand that some diesel might enter the oil.

My question would be how much diesel would be required in the oil to cause problems?

Does diesel in engine oil actually cause problems?

OK can understand that contamination in general is not a good idea.

How do you know when it is regenerating?

Would be interested in the answer, too.

I read that some people can hear the regen. when it happens.
That certainly is not true for me - the Defender is too noisy, resp. the MT tyres are. And/or my ears are too bad.
Anyway, I cannot perceive anything.

A friend who is a mechanic for Audi/VW, once drove an Audi and noticed a hesitation at acceleration/driving. Though Audi claims the driver wouldn´t be bothered by anything related to the regen.

Good question - never felt any difference when driving along that I could attribute to the regen but then I have never been certain when it is actually operating!

Would one of the aftermarket OBD readers be able to indicate this?

Say .. wouldn´t a EGT (exhaust gas) temperature gauge help in the matter ?

I have a PLX Kiwi2 WiFi ODB2 connected to the ODB2 port and clearly see it on my iPhone App. That is fine with me. Never forget: cars have owner, Landrover have field service personnel.

Unnecessary quote removed

What info are you getting/looking at to say the DPF is regenerating?

Landybehr, we meet again, common interest in this measurement I see.

Ninety Td4, can you translate all those acronyms into simple english so we have some idea what you're talking about?
