Swapped out the R for a courtesy Up! today, I saw the Fabia waiting there, but on warranty work notes I saw the typed words "please not the Fabia!". Can't believe how much quieter the Up! is than the Fabia, despite having the same 60ps 1.0 engine. It's a pity it stunk of burning clutch in the Tyne Tunnel with only 2500 miles on the clock!
Hopefully they'll replace something tomorrow or the day after as recalibrating what was already there clearly hasn't worked. I did ask how far out the recalibration showed the ACC to be from the factory's setting - still waiting on an answer for that one.
My salesman gave the service department some stick for seeing me again so soon.
