Hi, Jannez, I have identified and checked out this part and all seems OK. Also the heat shields mentioned in previous post, these are all secure. This noise is prevalent when driving at an indicated 32mph in fourth gear, which is slightlly below comfotable threshold for this speed /gear, as well as conditions in OP. I am currently having to drive about 1000 miles a week due to work issues, and whilst this problem is not getting worse, I am quietly hoping the offending item will drop off, so it can be fixed/replaced. Thanks for your help any futher suggestions greatfuly received, or it looks like I will have to be looking at getting a newer one. This will frighten moths out of my wallet when opened. :unsure: Regards, C Davis.
