Mirror Glass part number help

[richtung]

Hi Folks,

Noticed the heater element on the passenger side mirror not working that well this morning so decided to look for a replacement glass.

Found one on sale, brand new with part number: 5K0857521B (genuine OEM)

emailed a dealer with my car details - 57reg Edition 30 and he came back with part number 5M0857521E

Could anyone with access to ETKA confirm if the glass with the 5K0 prefix will fit? It is less than half the price of what the stealer quoted.

Thanks guys

Rich
