reset fuel range after new dsi

[James Moore]

hi all,

sorry been busy to post, but had my dsi replaced a few weeks ago and when i fill it up, the range used to show 350-400 miles on a full tank.

now it shows 250-300, is there something in vag i have to reset? to make sure the reading is right?

Does the MPG read correctly?

 

[James Moore]

how do you mean correctly? , it reads and moves, ie goes from 24mpg to 35 mpg et'c when driving slow and not on boost

 

[aragorn]

well does it give the expected figures? Surely you must have an idea of your normal MPG, and whether or not its displaying this or some other incorrect average?

If the MPG is correct, then theres nothing wrong with it, it'll probably just take a couple of tank fulls to sort itself out.

well to be honest, when i looked the other day it did seem low after the new dsi, as i remember if on the motorway and not boosting it would read something like 40 mpg but now seems lower

also to add, after the new dsi, the outside temp as well seems a good 10c out. Ie says 35.5c when i know its only 20-25c outside and that settles a little after a drive

update:

now the full tank needle has 30 miles on it, the range has moved to 350-380

must be a too full tank thing?
