I just had the high pressure fuel pump replaced in my 2007 335xi. When I got the car back it had a noticeable turbo lag that was not there before. Also the exhaust note and volume changed - much quieter now. I notice on the job sheet that in addition to replacing the pump they "program per gw code 80676090". Anyone had this problem or know what that programming code is? I am taking the car back Monday, but can use any info anyone has on this. There was something very similar to this in the letters section of the January ROUNDEL.
