got mine fixed. £150 for a inlet manifold from a breaker (good one). Local garage swapped it for £120. Total cost: £270. Fantastic engine sound and engine much stronger. Called land rover garage in Aylesbury for software upgrade. 20 minutes and four different people later, the service manager did not know about the V6 inlet issue (???) but was happy to ask for £130 for a software upgrade. 30 minutes while you are waiting sir. I told him it should be free according to land rover club and he kept telling me the car is out of warranty. Called Land rover customer service and got a very cold reception.
As the service manager did not know about the issue, I thought there was no point spending another £130 to upgrade the software.
BTW, while waiting between people, I had to listen to a advert about great finance on new LR... well, with that type of awful service... no thanks. Other car is xc90 and I have to say, phone reception is night and day with LR.
