2006-2009 Range Rover Sport
Heads up... Land Rover is trying to identify a possible issue with the new 5-liter supercharged power plants of 2010 RRS and FFRR. Apparently there have been complaints of rattle and knock noises originating from the engine compartment (can't say I have heard of this on the forum up to now), and the supercharger assembly is suspect. The Eaton supercharger of the outgoing 4.2 liter engine has been a model of reliability, hopefully that won't change in 2010. ray: It takes 4 and 1/2 hours to replace that sucker! Special Service Message quoted below, this won't be escalated to an "official" TSB until/unless Land Rover finds the cause for the reported noise.

Title 10MY 5.0 Supercharger Noise
Last Modified 26-APR-2010 08:12
Symptom 497000 Engine Noise
The customer may complain of a rattle/knocking type noise from the engine compartment.
If the above stated issue is reported by the customer please remove the supercharger drive belt, if this rectifies the noise concern please raise an EPQR and order and fit a new supercharger assembly. Please retain the old supercharger as it maybe required for engineering investigation purposes.
NOTE – It is imperative that the supercharger assembly is returned in the exact condition as when removed from the vehicle. Tampering/opening the assembly once it has been removed from the vehicle and returning the assembly in this condition invalidates any potential investigation to determine root cause with the supplier.
