Error lights came up on dash, TC, ABS, Stab Cont, Diff Lock with 3 bells

Also, curious on how you would use scan gauge to reduce fuel use ? ? Am I missing something ?

Thanks, Rob

Scan gauge will show you instantaneous and average fuel use.
You will be amazed at the difference just some small driving habit changes will affect fuel use
When and when not to use 5th esp when towing...
When to downshift gears...
When driving like Miss Daisy is actually worse (CRDs in any vehicle tend to like firm acceleration up to cruise etc rather than 'softly 'softly on the gas)
If you stay away from the really high fuel flows the change in Litres per Hundred K's is well worth it and hardly noticeable in trip time etc

They display 4 parameters at once so I usually had mine set to Boost pressure, Coolant temp, Avg fuel and the 4th depended a bit on what I was doing
