Review on LR023964 Air Suspension Compressor Pump (Hitachi System) for LR3 2005-2009, LR4 2010-2013, Range Rover Sport 2006-2013 (6-Pin Connector) LR044360 by Kevin Ilango

08/07/2019: I bought this compressor in March 2019 and after only 4 months of use it is already a problem. Started getting louder last week and yesterday it sounded like a box full of balls and cursed for low power. My local LR shop has reset the system multiple times with no change. Still wrong. The compressor shakes a lot and sounds terrible. The store said it was junk and needed a new one. Now I can't drive my truck. I wrote the seller a letter asking for a warranty replacement or refund. Will update this review with the results. Sent another email on 8/11/2019 asking for a replacement or refund. Today I sent a third letter asking for a replacement or refund. Gave them scan info showing low output error. 10/9/19 There is still no help or response from the seller regarding a replacement under warranty.
