Mansfield 4x4 [Northern Way. Bury St Edmunds] have looked after my 4.4 TDV8 since Sept '19.
I've had one major service & a couple of visits to cure a 'restricted performance' issue which after a little faffing around, turned out to be the turbo actuator arm [tight] and also oil in the actuator itself.
Had the 'hesitation' software upgrade as well.
Frank [owners son] looked after her on the last visit, spent hours trying to find the culprit as there were two fault codes.
Labour rates are very reasonable and so far, can't really fault them.
They specialise in the older LR's & off road Landy's possibly more than the L322/L405's but there's always a host of models being worked on.
I have no affiliation with them except as a satisfied customer and the above is purely my view from the service I have received.

Hope this helps if you're looking for a decent Indy. 2012 Orkney Grey Westminster 4.4TDV8 with Ivory interior.........nice!
