Hi

Just had my Grande Punto serviced by Halfords and now the trip computer that shows the range of miles left before fill up has changed.
Before it was showing nearly 600 on a full tank of diesel and now shows only 450 miles.

Any ideas?

Thanks
Ian

The range is based on how it's been driven, they may have driven it 'enthusiastically' while it was in their 'care'. It'll still go as far under your careful driving, and the range indication should go back to around 600 after your next fuel up.

They probably reset the trip computer instead of the oil change interval.

If the last thousands of km you were driving reasonably, then you could expect the decrees from 600 to 450 to be based on a few good hard pulls.
