Is your M54 a non-si, I cannot remember how these work, I know you had put reokacement M Sport seats into the Coupe I came to look at, a nice and in my view essential touch for that really sporty feel!
M54 is the 6-cyl engine in the pre-facelift cars - 2.2i, 2.5i & 3.0i. Mine is a 3.0i
N52 is the 6-cyl engine in the post facelift cars - 2.5i, 2.5Si & 3.0Si. Coupe is 3.0Si only
All came in SE trim or Sport trim, the latter with lowered sports suspension and M-Sport seats. My coupe was a SE, much improved by the addition of M-Sport seats, so I have done the same with the roadster which is also an SE, but ironically it was specified with sport suspension (unless all three litres came like that ).
