Ok, I am aware that the oil pressure light does not show with ignition on or during start up, and before Sunday this week I had never seen mine. Got in on Sunday, fatty had been driven on the Saturday, started up and the light came on after start up for around I would say two to three seconds. Turned around stopped turned off, re started all fine, no light. Drove 50 odd miles, all fine, stopped for two hours, prior to re start checked oil level, bang on the max, re started all fine, 50 miles home, a dpf regen, all fine. Didn’t use on Monday, started this morning, got the light for perhaps 1 second after starting, drove to work, 7 odd miles, all fine. Got back in the car this evening, no light on start up. I’ve searched the internet pretty thoroughly and can’t find any ref to oil pressure issues on sdv8 or tdv8 engines.

Any experience or words of wisdom? Last oil service was in December and I’ve probably done around 4K miles since.

Checked it for oil leaks around filter? Whip off engine cover and peer down.
Any codes on IID?
Checked oil level when cold first thing in morning? Should be a couple of notches below max. Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

Checked this morning, level shows a few clicks down, no oil around the filter and no light today, I did notice the two times it’s come on I was facing up hill, not come on down hill or on the flat. It’s in for gearbox oil change tomorrow and full front arms doing etc so I’ve asked the garage to pop a pressure gauge on and see what actual pressure I have on idle.

Cool. Which garage? Mark Kelly? Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

My local mot center whom I trust very much, have done some serious jobs for me in the past and friends, they undertake pretty much anything and are very good.

Hello! Did this get resolved? I am getting exactly the same symptoms on my 2011 TDV8, except oil light blinks on regardless of whether on flat or slope ... any advice greatfully received. Engine shows full of oil and only recently serviced by local main dealer, driven some 2000 miles (thrash to Spain and back in between lockdowns) ... thanks for any help Simon

Hi, changed the oil and filter and it’s not done it since. It only did this 3 times with enough miles in between to know it wasn’t immediately terminal. Probably don’t 700 miles since change.

Many thanks TrevCOSS for replying, that is very helpful. I had the car serviced in June 3000 miles ago. Only started doing this in the last few weeks, after a good run to Spain and back. I'm not getting any oil leaks around the filter (or, unusually it would seem) anywhere else in this engine, but I am getting quite erratic oil level gauge readings - it will sometimes swing from "needing 1 litre" to "overfilled" in a few seconds though normally hovers around the "full" level. Maybe something clogged around the sensor or pressure gauge. I'll get my local dealer to look at it, though they charge a fortune just to open the bonnet and take a look. Joys of RR ownership! Many thanks again.

Put a reputable engine flush thru the engine before the next oil change, as you said it might be a small deposit on or near the sensor. The flush should breakdown and remove this type of thing. I always use engine flush before oil changes, you will be very surprised what comes out, especially if it's the first time you do it.

Avoid main dealer. Plenty of independent specialists around the south.

Thanks Laurie, Dr Rob, all good advice. A good flush certainly sounds appropriate, I'ev done it on previous cars but not in the 15 months I;ve had this one. I expect most previous services will have just vacuumed the oil out, which I fear will leave any crud behind, and after 103k miles/165k kms I'm sure there willl be plenty. I'll try West 4x4 they're just down the road, I'd stuck to the local main dealer (now called Inchcape they used to be H A Fox) as they were close to where I work and looked after out previous car, Jag X-type 2.5 V6 ( four wheel drive) very well indeed for ten years (until it was 15 years old) and not particularly costly either. I'll let you know how I get on.

BTW, for any body else reading, what a great forum this is and so helpful to me over the last 18 months+ since I first started looking for a Rangie, it is a complex beast but somebody has previously had all the issues, and taken the trouble to post their solutions, so I've fixed a lot of minor problems myself (driver door cable failed, leaking sun roof drains, rear seats not latching correctly, reprogram remote heater fob thingy) and understood the problems when I couldn't fix it (fuel gauge sender, fuel pump failure) so I don't sound a total muppet when I go to the garage. So, many thanks to all. Simon

OK sorry for not getting back sooner but it has taken this long to sort. Mark at West4x4 was very friendly and informative over the phone but "booked solid till end November", Barclays 4x4 in Southampton were closed most of the Autumn bu when they opened they refused flat out to flush the oil, saying that, on an old car, it did more harm than good. Inchcape main dealer had a poke around, adjusted the oil level (they thought it was a little too high) and put a pressure gauge on the pump, saying it was ok, but again would not flush the oil. Mind you they didn't charge me for it either.

So last week Mark West took it in, flushed and changed the oil and filter and put a new pressure switch on while he was at it (the part was less than a fiver). I hope I'm not bringing the wrath of the gods down on my head for saying this but ... the problem does seem to have gone away.

So, many thanks to Laurie, Dr Rob and Trev for your advice. I'm now onto the next problem, driving home from Bishop's Waltham (West 4x4) I got the "adaptive dynamics fault" light up, sounds ominous but again thanks to helpful advice elsewhere on this forum I've found the two broken wires and just need a dry day to sort out some soldering.

All the best for the New Year

Good news Simon! You've reminded me to fit the new AD looms I bought when my fault came up. Mind you, I soldered the wire and it's not done it since so I'm loathed to dive in just yet
I've just had a new starter motor fitted (Denso) as mine was getting sluggish. The difference is amazing! Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"
