Wind noise drivers side over 40mph. Mines going back but I have a bit more proof from an experiment I did today that it is indeed the quarter glass
After the third time back at the dealer they said its a known issue with MG now but no official fix they could apply and be paid for
Is that straightforward to do?I agree with @FiferMG4. It sounds like the same problem some were reporting with wind noise from the passenger side. The solution was to remove the quarter-light and reseal it.
