T5 Auto 128kw problems?

[BobD]

With my 6sp man i am getting 8.6-9L/100k using DP tuning module. All up it weighs 2490kg,

What is a DP tuning module?

I assume you are not talking about a Multivan with that consumption as they only come in manual with 4 motion. What model is it?

It is a double door swb transporter, DP module comes from Berrima Diesel. It improves power and torque from 128kw-400nm to 155kw-455nm.

Does yours have the particulate filter like mine has? I would rather it didn't as it seems to increase fuel consumption and the manual also says you can't use bio diesel.

My 6 speed manual 4-Motion TDI gets around 10.5 l/100 Km's around town. This appears to go down significantly on highway driving. Recently did Adelaide/Alice Springs return, and got around 8.5 l/100 Kms.
2005 Multivan Highline, 128 Kw 4-Motion with DieselPower chip.

I have a 95 t5 multivan tdi auto with 90000klms. I have averaged 8.4l/100 since new.. On trips i can get as low as 7.3l/100.
AC costs around 0.5l/100 in my experience.
I can't understand how your economy can be so bad unless in traffic jam.
Towing a large fiberglass boat I get about 11l/100ks
The AS rating of 8.9 is very good indication of expected economy with mixed city and country.

I assume you mean 2005 Multivan as the T5's didn't come out until late 2004.

I was expecting 8.9l/100km at worst as I was getting great fuel economy from the T4 TDI. My computer tells me it is getting about 10.9 but the fuel pump is telling me over 11, consistently since I got it. Most of the driving is around town but it doesn't seem to change much on the couple of long runs I have done.

As I said my Multivan has the diesel particulate filter, climate control, all the electronic gizmos under the sun and other strange things in the engine bay that I have never seen before. Does yours have the particulate filter, Bert? I notice that the specs in the manual show significantly higher fuel consumption with a particulate filter versus without.

Anyone else getting similar fuel consumption to me in the 128kW auto Multivan?

Yes Bobd your right my 128kw multivan is a 2005 model. And mine has all the electronic gizmos like your which make little difference to economy except for the climate control. All autralian multi's were the same spec. We don't use climate control unless in summer. Can't understand why you would use it otherwise. I also have a friend with a 3 month old multivan reporting the same economy as mine. The AS rating is easily achievable and a very conservative indication of economy.
An observation worth mentioning is when the vehicle is cold the economy is bad. If a large percentage of your trip is prior to the engine reaching temperature then that would impact severly on your economy. Also keep your foot light on the gas until the engine is at full temperature as you would be surprised how bad this can impact economy.
Maybe take it out on teh open road and test with warm engine to see if something is really wrong.

You raise a point that I only realised about 2 weeks into new ownership, I drive a lot further after an overnight stay/cold start before the engine is fully warmed compared to my previous T4 dual fuel van......it takes alot longer before full warm up.
