According tom "Letters" in the January issue of the Roundel, there is a problem with the turbos in these new engines. Specifically reports of "rattling waste gates". Warranty fixes have been new ECU software is now opening the waste gates from idle. This new change not to engage the turbochargers until 2500 -3000 RPM. This is "a far cry from the 1400 RPM, 300 foot pound kick that original 135i and 335i owners have come to love.
Several letters about this problem with the Turbo's in the January issue.
What are the thoughts of many????
