Hi all, 2020 420i , has anybody had a remap ? Am not sure because i think it could be detected at BMW dealers... Also what mods have you done... thanks in advance...

Hi Gary

Welcome to the Forum

No one come to help yet ?

I don't know where you are in the country so this may not be much use but here goes. 

My Brother In-law has used BW Auto Repairs in Hayes/Uxbridge West London for ecu tuning on his last 3 BMW 5 series his cars have all been purchased new and serviced by the supplying Dealer (North London) with no comment. He has interim oil and filter changes carried out outside the dealer network (often on my drive) BW have their own rolling road and are BMW specialists so know their stuff one point all his cars are the 3.0 turbo diesel.

When I owned the Volvo's they were all ecu tuned it became so common the Volvo Sweden started offering Polestar upgrades themselves.

I would give them a call and ask what can be done without putting a dent in your Warranty
