Great thinking Knares I like it...

The car is a 7A vin so this screenshot from JLR classic parts suggests YWC500521 is correct and a later part number can also be fitted in succession to the original.

Been looking back at my pump pressure test and I do see an anomaly.

According to the WSM the relief valve in the pump should limit pressure going to the rack to 114 bar +/- 4 bar so that's a min of 110 bar and max of 118 bar.

During my pressure test I saw 1750 psi or approx 121 bar.

This is higher than the specs though?!

Also the pump itself is marked with a sticker stating 132 bar?

Does anyone know exactly how much pressure the rack needs?

The 2007MY workshop manual doesn't have the information but I found a 2002MY manual which states I should see 8 bar at idle and 133 bar at full lock. (Screenshot below)

Obviously a 2002MY car has a different pump but I'm sure the rack is the same 2002-2012?

On my pressure tests I saw approx 4 bar at idle and 121 bar at full lock...
