Would like some info on the correct pre-cat Bosch lamdas to buy for my P38 - 4L - 2001 (Thor) and if you know of any non rip off stockists ( not LR main dealers though)
Heater circuit duff one one and the other has given up the ghost.
Not too keen on OEM or items made in soup shops in Taiwan !
Grateful to Simon for sussing out the defects.

I'd been waffling on to myself about buying a RR V8 for what must be the last ten or so years, with my main aim to have an LPG jobbie.
Took the plunge a few weeks ago and managed to find a (up to now) good non LPG P38 (2001) with excellent maintenance history, just a few minor niggles, a la saggy liner at rear, and grumbling front windows.
Well pleased to get 21 mpg around here (Nth Wales), luckily clearish roads and very little stop start.
She's off to have an LPG ectomy in a short while, that's another item off my bucket list.
LPG @ 55 litre in Anglesey and 65p in Bangor - so will go the extra few miles to Anglesey when possible.........penny pinching or what ?
Great forum by the way - no doubt I'll be asking for advice somewhere along the calendar.
