Mk4 2000 MY 1.8T 150bhp remapped 3 years ago.
I recently used the car on the motorway and noticed the MPG indiactor was "hunting" it zoroed out then seemed to reset itself, then slowly climed up to 200mpg the started to drop back down to around 9mpg then back up again. It did this when i came off the motorway too but the mpg did not have such a great high to low range. I have tried a few ignition cycles and the problem persists. I do not yet have any diagnostic equptment (but can borrow a basic tool)so have no dtc's to post.
Any ideas folks before i go any farther???

firstly welcome :smiley:
2ndly - press the rocker button on your wiper stalk to cycle through you trip computer :wink:
3rdly - stay and enjoy the forum :smiley:
4thly - read your owners manual if you have one :tongue:
-
yes someone mentioned the stalk reset to me today, i will consult the owners manual, just thought it was unusual for this to happen.
thanks. :undecided:
I read the manual and did a stalk reset, now all is well. It does pay to read the manual. CHEERS
Ive not had the car long and it did seem unusual. :rolleyes:

you have several options in the trip computer :smiley:
the one you stumbled across is you instant MPG so it works out roughly how much fuel you are using depending on throttle position, speed, engine load etc etc
the computer resets 2 hours after the ignition is switched off although if you have a 2 in the corner this is your long term computer and resets after 99 hours and 59 minutes of driving

Rhys, your just a wealth of knowledge!!! :smiley:
I never knew the Number 2 comp programme reset after 99 hrs!! That explains why my long term mileage on it zeroed then! :smiley:

cheers Scott :smiley: nice to know my knowledge is somewhat useful :smiley:
the No2 trip is useful for working out your proper long term MPG (if you're into that sort of thing :laugh:) and will actually closely match your fuel consumption per tank :nerd:

As this is in discussion, how many of you reset the trip after a short journey?
If i drive for say 7ish miles stop the motor leave it for an hour then get back on the road, temp gauge reads 90 and trip 1 says 41mpg.
Reset to zero do the same journey back it'll reach 60mpg easy? :huh:
Anyone done this? I'll assume its a false reading? :undecided:

yep its a false reading really as your car is up to temperature in no time at all so will give you a much improved MPG figure :smiley:

i do it sometimes if my car has been into the garage and been left idling or taken out for drive around the block (dread to think how they actually drive it mind!)
-
I am really happy if my MPG is over 40mpg, but of course some drivers (thinking of a certain Indigo Blue driver!!!) cry if they get as LOW as that!!! :grin: :grin: :grin:

:cool:
-
what were you doing like 20mph?? :huh:
or is it because you're car is no longer farting its boost over the road? :tongue:
-
Steady trip home from work, sat at about 60.
Most probably down to the fact I have more power lower down now so dont need to use the engine so much :smiley:
-
You diesel boys just love to torque!!! :grin: :grin:
-
I got 41MPG average over the trip to Leicester including on the RR.
-
Since I have sorted my boost leak my mpg has gone up. On the Leicester trip I got 33mpg but since last Tuesday when we sorted the pipe work, I filled up the same day and the "miles to empty" started at 310miles, asnd since driving on the tank its gone up to 375miles!! My car makes fuel :grin:
Seriously though I think on a run it would do 40mpg easy. will post up when I do a good run :wink:
