I have been searching other forums in regards to this rattle and have a possible fix.......
According to some members on this forum Common rattling noise between 2500-3000rpm cause - VW GTI MKVI Forum / VW Golf MKVI Forum / VW R20 Forum / VW GTI Forum - Golfmk6.com they have singled out the FLEXI bend on the DP as the rattle. Have a read, and if anyone on here has replaced there DP can advise.
Thanks
