RE: New to Me 2008 TDV8 Range Rover Vogue

[BusinessConnected]

Good Evening Guys:
Has been quite a long absence from Land Rover Ownership for me.
After having some D3's for quite some time I went Electric with a Tesla for quite a long period of time.

Anyhow I've recently purchased a 24 Foot Bayliner Cruiser for some Summertime fun with the Kids, and the Old 100 Series Landcruiser Petrol just wasn't really cutting it towing.

Hence the Purchase of a Lovely TDV8 3.6 2008 Range Rover Vogue from GraysOnline.
Now this purchase was fairly cheap.. so I expected some issues... and I've certainly got some :)

Drove the Car Home today.. Was fine except for the occasional "Engine Fault' Message Under Load.
Pulling over to the side of the Road and Restarting the Car brought the Car back to normal operation.

After I got home I was able to connect the MaxiDAS DS708 Code Scanner and retrieve the following codes.
P2269-68 - Water In Fuel Condition Intermittent
P023D-22 - Manifold Absolute Pressure - Turbocharger/Supercharger Boost Sensor A Correlation
P132B-21 - Turbo Boost Control A Performance

I'm hoping that the Water in Fuel is probably just a legacy of Melbourne's Drenching Month or Two at the moment... I've purchased a Service Kit with New Oil/Fuel & Air/Cabin Filters which will hopefully address that issue.
I've done a bit of research on the other issues, and the fact that the Car seems to perform "normally" after a Restart tends to point towards a Hose Split on Drivers Side Perhaps?

If anyone has any further information or advise that would be fantastic :)

Just wanted to give some further details today.

Cleaned Air Filter (which was pretty dirty... New Service Kit on Order) and did a MAF Clean with the MAF Cleaning Spray.

Did some Testing in the National Park behind us in Kinglake here and was basically able to recreate the error under Load on Hills etc in either D or S Modes.
Only getting one error code now.

P023D-22 - Manifold Absolute Pressure - Turbocharger/Supercharger Boost Sensor A Correlation

I suggest that the left and right MAF and MAPT sensors be swapped to see if the fault stays on the same bank or if it swaps sides indicating a faulty MAF or MAPT sensor.

The top hoses are renowned for splitting underneath so they might have to be removed to be checked properly.

Hi
brought a 2008 Sport for purposes of towing horses around the country with the 3.6 V8.
These are great towing vehicles, however after 4 weeks ownership I had the thermostat stick closed while towing uphill which blew a head gasket and cant seem to get any Land Rover garages interested in fixing this or locate a 2nd motor.
I would strongly suggest you change the the thermostat and housing.

Graeme:
Thanks for that... I'll give them a swap tomorrow and see if the Codes etc changed.
Is it possible to have the MAF's wired incorrectly since their are two...?
(Or does the Car not run well at all)

Just an Update:

Swapped the MAF's today and Swapped/Cleaned the MAPT Sensors.
MAPT Sensors were a bit oily/dirty so a good spray with the MAF Cleaner brought them back to new condition it seems.

Did a Test on the Uphill Route near my House that was faulting regularly yesterday and wasn't able to get the Car to Fault Again.
Will do some more driving under load later today but hopefully issue may be resolved fairly easily. (Touch Wood).

Spoke too Soon :)

Went for a Longer Drive and coming out of a Roundabout it toggled the P023-22 Starting to accelerate to 100kmh again.
Stopped to read the code and then proceeded up from Whittlesea to Kinglake West (~Sea Level to 400m Long Hill) and it prompted Engine Fault again about 200m up the first incline.

Pulling over, Restarting the Car and Manually Shifting the Gear to Sport and downshifting to 4th Gear ~2500rpm got me up the hill without error and once on the Flat again... Drove in Drive normally.

Based on the symptoms etc... and the fact I have Newish looking Silicon Intercooler Hoses.. I think my next avenue is to have a bit of go down the similar path of
Range Rover Sport / Discovery TDV8 boost leak, cracked inlet manifold, P023D error - YouTube (https://www.youtube.com/watch?v=neTJs7nyc00&list=PLQXdcoMTlFqripj0OzMVzZ7B0gdp5mGmL)

See if I get any leaks from that RHS Inlet Manifold.

Follow Up again after some Sunday Afternoon Diagnosis.
Did a Lead Test using a Radiator Compression Test Kit I had... mixed in with an Adaptor to suit the Air Compressor.

After Botching that onto the Silicon Hose on the RHS of the Engine I've discovered the following.

182138

(Video Taken when Idling.. I first tested with the Compressed Air and saw more bubbles)
The Gas & Leak Bubble Detector shows some bubbling on that Intake Manifold.. Even at Idle... I'm sure under Load it's even worse.

So now off to essentially follow the directions of Paul_V at the Link Below:
2010 TDV8 right hand valve / cam cover / inlet manifold replacement (https://www.aulro.com/afvb/l320-range-rover-sport/292849-2010-tdv8-right-hand-valve-cam-cover-inlet-manifold-replacement.html)

I'll probably order both sides to have them ready to go.
Think I'll pass this one along to my local Diesel Mechanic..
