these are the numbers of the 3 versions of phase 2 turbos (136 bhp)

1) 454150-0004
2) 454150-0005
3) 454150-0006

the numbers are on the turbo somewhere, but haven't found them yet on mine... but note really looking since it's working A-ok with 130k on the clock, checked for play today and none there

if your car is 2003, it would have a garratt GT2256V turbo fitted, totally different from a 136bhp turbo.

Thanks for all your help. My car has face lift interior but no facelift exterior would this make any difference. these are the turbos listed
2.4L D 841C.000 01- GT2256V Garrett 710811-0001/2 46769104 JTD 136 bhp
2.4L D 841G.000 03- GT2256V Garrett 717661-0001 46808717/55182571 JTD 175 bhp
2.4L D M728.2387 03- GT2256V Garrett 750639-0002 55191599 JTD
Any ideas

What is the engine type number quoted on the chassis plate?
of the 10v 2.4JTD
32501 = 136bhp
839A6000 = 140bhp
841C000 = 150bhp

The face lift interior means that it is the 150bhp model ...
