Hi,
So I upgraded from 16" alloys and 255/55 tyres to 18" with 225/40 tyres. Not a huge difference in size really but my trip computer is being pretty weird, telling me I have 325 miles in my tank when it only ever used to say 310 on a full tank with the old alloys on. Also I've noticed that I set off '30 - slow down' signs and general 30 speed limit electric signs when the speedo needle is just under 30, so more like 29. Would like to get this sorted as it's getting on my nerves not being quite right.
I've searched around for this all over the net and no one seems to be able to give a straight answer, a lot of the threads seem to evolve into tangents etc. I've heard lots about speedos generally being optimistic in terms of speed, but this seems the other way round and it's getting on my nerves a tad. I would imagine it's also affecting the mileage on the car too?
Is this something that can be done with VCDS? Cheers
