I agree, it’s about overtaking safely when needed and not having to downshift three times to get up a moderate hill for me. Although overtaking still needs a bit of a run-up!It's a fair point, right tool for the job and all that. Was never expecting it to be a rocket ship, just a bit more oomph to help with safely passing the 40mph in a 60mph types who seem to have their HQ down here.
You need to reset your expectations by driving around in shit cars for a while.Don't get me wrong, it moves around just fine, but it's my first van so I'm (wrongly) comparing to the sportier VAGs from a former life![]()
That's likely a gearbox thing (assuming you have DSG...)if a little ponderous on throttle response
Yup!That's likely a gearbox thing (assuming you have DSG...)
So the school run and local driving is the worst situation for any modern diesel. They need a good blast and clean out every week. Running under quarter of a tank won’t allow the regen to work, so try to always run with more than 1/4.Certainly the first one, the van is used for the school run more than we'd like (15 mins there/15 mins back). It gets the occasional longer trip every 2-3 weeks of 1-2 hours. Fully aware that's less than ideal for a DPF equipped vehicle, hence looking for a run around to spare the van from those trips.
With 27/28mpg, it quite often finds itself with less than 1/4 a tank...

As mentioned via DM we’d need to take a good look at it to work out the issue. It’s very hard to help diagnose without the physical vehicle. Some datalogging and live readings would really help see what’s happening.

Which of the sensors?a sensor in the DPF

Data logging and verification of the fault P226D was done here (post #66)what to log/monitor and how to drive while logging, I can try and do that and post the results.

Is the exhaust tailpipe sooty?

[T6_measured] Monitoring DPF regeneration, DPF condition, EGR operation
@ebiii Attached an addendum to Torque - containing the following T6 PIDs "T6-01 Lambda" "T6-01 NOx sensor" "T6-01 Particle sensor current" "T6-01 Particle sensor operation time" NOTE: "T6-01 Particle sensor operation time" will be logged only once in 10 seconds - to not unnecessarily slow down...www.t6forum.com
Been given a couple of places to try nowAny decent independent will know what to look at and test. Do you have a Transporter specialist near you?
Oh wow...Thanks, it's not related to the issue.
Definitely not a good sign!
Below mine after 6 years. Only faint stains can be seen on bright white towel.

I would say that the DPF matrix is damaged and the van is running fuel rich, that exhaust IMO is very sooty even by Euro 4 standards. This would explain the poor MPG.Oh wow...
I was just reading elsewhere I should be able to run my finger on the inside and it should be clean.
Do you think this is pointing to a breakdown/failure of the DPF itself and the EML fault is telling me too much soot is getting through? Would this also explain the poor fuel economy if the DPF is failing?
It hasn't been checked for boost leaks but I'll put that on the list.I would say that the DPF matrix is damaged and the van is running fuel rich, that exhaust IMO is very sooty even by Euro 4 standards. This would explain the poor MPG.
If you have Carista Beta you can monitor the injectors in Live Data.
Safe to say that the DPF is knackered and if I were you I’d be removing the map and getting the injectors checked.
I’d also be doing an oil / filter change, if there’s this much carbon going through the exhaust I doubt the engine oil is very clean.
I assume you’ve eliminated the possibility of a boost pressure leak?
It’s there, have a fish about, I was looking at mine just 2 days ago.downloaded the Beta version of Carista but couldn't see the injector data anywhere in Live Data?
