Thread: D5 owners (or prospective owners), read this

There is heaps about this on another thread.

So if the oil dilution detection system fails,there goes an engine....

Washing fuel into the cylinders as part of normal DPF operation doesn't seem good for the bores and rings either.

We have a Tojo work van with DPF,has about 50000K on it and no issues at all.

Just does the regen every so often by itself,sometimes upping the idle.

Reading the UK Land Rover forum threads, it claims that LR have pulled this bulletin, as it been doing the rounds on the internet and would no doubt been causing them some grief.

I”m really hoping they have pulled the bulletin because they have solved the oil dilution issues,
but I doubt it.....

my new D5 arrives in late January/ early February, any ideas what to do?

If you are not driving short trips and let the DPF regen complete its cycle you will be OK. Most of these problems come from short trips. If possible run an additive which will assist combustion helping prevent the DPF from doing a regen as often.

Interesting read, my discovery arrives late January and will be travelling around this big country of ours
hope I made the right choice

you have to treat a Diesel engine differently to a petrol powered vehicle and many people don't or are unaware that they should.

as stated above this should really only affect vehicles that only ever do short runs and never pull a load as they will clog a DPF quickly.

pulling a decent load regularly ensures the DPF gets a good clean out and ensures the bores don't glaze excessively in my experience.

high revs on a diesel motor alone, does not load the burn cycle. pulling a heavy trailer, pulling a van or a horse float does.

as with the earlier Diesel engines if the vehicle is never loaded then you should use something like Cost Effective Maintenances FTC DEcarbonizer

i used it on my late model VW with DPF and i had none of the issues many others had with the DPF setup.

i also use it in 2 @ 300TDi powered land rovers as they tend to glaze their bore if not used to pull a decent load on a regular basis.

it does make a significant difference and is a far superior product to the others i have tried over the years.

That would depend on how the regen activation is triggered. Some may trigger on fuel burn, some may be on DPF differential pressure etc.... If its monitored from an actual differntial pressure sensor setup then yes you could in reduce the DPF regen cycles. If its calculated from a fuel burn rate from the manufacturer then it most likely wont make much difference as they will do a regen for whatever its been calculated/programed to do

I didn't realise that some regen on fuel burn my only experience is differential pressure. Hopefully fuel burn is mainly on commercial vehicles (ie. trucks) as I haven't heard of it being used on passenger vehicles.
