What kind of transit do you have?
I am on the 17 seat MK8 minibus. Done 5,000 miles in the last 5 weeks. So far so good, except for the limiter. its meant to be set to 62mph but ford have released them all with speeds up to 70mph. (no use for PSV tacho).
Because i've got the new 'panther' engine the software the dealer has isn't up to date. They can only set it to a maximum speed of 59mph (58mph on cruise). Very frustrating trying to pass lorries. Getting nowhere with ford on the issue.
I did notice it has got through a few litres of adblue already. Been told not to worry about the DPF as they "burn clean as a whistle" We will see on that one!!
