Increased fuel consumption by raistlin

VeeKay is proving to be a tad thirsty at the moment :(

No other indications beyond increased consumption that I am able to perceive. Russ had her on T4 (Testbook version 4.Computer Diagnostic System) a few weeks ago prior to the 160 re-map and the engine was sound as a pound.

Doesn't seem related to the re-map as it has only been the last week or so that I've noticed the change in consumption.

I suspect there are a plethora of things to check so would anybody who knows be kind enough to list them for me please?

MAF (Mass Air Flow Sensor) Sensor (out of spec or snide Bosch one?)
Wrong setting on Synergy Unit (if fitted)try turning down slightly
Dirty Fuel Filter
Fuel leak from damaged or corroded fuel lines
Blocked Dirty Air Filter
PCV (Positive Crankcase Ventilation Valve) Unit
Leaking hoses (More difficult to find but only needs small hole)
Dragging brakes
Handbrake not releasing properly

........and a heavy foot or cold start mornings in a Autobox car

Just a quick few from memory, will find full list later Paul.

i went thro this two weeks ago.mins has every thing checked but in the end down to the fbh running most of the time which was due to faulty sensor.but as it was new and the freelander one with a wider operating range i did not suspect it.this in part was because i did not.and for that matter still dont no what the range of this one is a opposed to the standard rover one.

Thanks John :) I've now worked through he list and can find nothing wrong. I can't confirm leaking pipes though, other than a visual check.

Paul.
If it went on its own something must be sticking maybe EGR (Exhaust Gas Recirculation Valve) staying closed when it should not thats if you have not done the bypass or did it change when you replaced the air induct ? did you recently change the PCV filter etc best to try and find out otherwise it may come back with a vengence :roll: ad you may end up having to get a V8 ;) no best to have a good look at things in July meet wont hurt Arctic

OK Steve :) At the July meet then - assuming nothing gets in my way. FYI, the EGR is bypassed and I haven't changed anything else recently.
