At the risk of demanding this bus go to Cuba (aka Hyjack alert) I would be interested in your experiences with the SG.
I decided I couldn't wait so I topped up my tank. The tank itself was my best (or second best I can't remember) and when I told SG it recorded an adjustment % which I assume is the difference between what it thinks I used vs what I did.
The immediate 2 effects of this were :
- GPH adjusted from 0.2 GPH at idle to 0.14 to 0.16, not stable yet.
- MPG has adjusted but doesn't match the OBI (On Board Instrument). Having tapped that the OBI is optimistic and the SG2 is below that so maybe its more realistic.
I may do some video comparisons and maybe people can comment. However I would be very interested to know what your V50 does.
Disclaimer - I do realise that the SG2 vs TDi MPG issue has been debated, but
