How "officially supported" are these remappers? Do they affect warranty or servicing?
My Mk6 GTI is leased, a company car, so all servicing bills and warranty etc is owned by the leasing company.
I dont imagine they'd approve of me installing a remapper - but if I did, are they ever likely to find out?
Is it something I can remove before servicing?
If I do remove it, will the dealer know its been installed - is there a record somewhere of it having been remapped and then removed?
I'm sure you get the picture - any help appreciated
