What are some common faults to look out for . Probably be looking at a car with around 100,000 kms on the clock
So how have you been going so far . Anything major go wrong.
Currently have an L322 TD6
Thanks for your help guys

My 2015/16 SDV8 Autobiography has just ticked over 50k with zero issues 🤞 I fitted 20” rims off a sport about a year ago for towing & any dodgy roads.

I'm also contemplating turning over my 2016 D4 in the next 6-12 months. Fortunately I've got the e-diff now and would love to have it in the next vehicle.

TIA

I don't know about the L405 (too lazy to look as well) but the RRS with SCV8 had the e-diff and I understand any vehicle with Dynamic mode has an e-diff (I could be wrong).

My L494 SCV8 consumption is 18l/100 city, 14l/100 highway, 22l/100 towing my 2.9t ATM caravan. My city driving is often stop start peak hour Sydney.

I had an engine issue with excessive noise from the drivers side head. This turned out to be a worn exhaust valve tip and lash cap causing excessive clearance. It was an expensive job to access and repair but the repair did include having both heads serviced, replacing all exhaust valves, replacing 5 injectors, replacing spark plugs, servicing the supercharger and replacing all plastic coolant lines and the water pump.

I’ve got a SDV8 MY17 with 80000 on the odo and fault free; I’ve had a D3 D4 L322 (MY12 SDV8) and now L405. This has been the most reliable, with others all held to c120,000kms. I’ve modded it a bit: three inch exhausts (wouldn’t do it again, dont get same benefit as L322 without dpf); uhf, Redarc, LLAMS, LT275\55\20 Ridge Grapplers on a second set of rims; dual battery system with Aplug and solar input etc

Tows superbly.

11/100km around town but that’s with a lot of tunnel and only a little stop start.

Have seen 8/100 on highway with ease.

Overall, great car, no regrets and no plan to upgrade anytime soon as the V8 is sublime!

Cheers

First issue at 82000km - slow oil leak from Oil Cooler; being repaired under Warranty (5year) albeit 6 week wait for parts …. Sigh ….cheers

My L322's turbo oil feed o-rings were replaced at 82K then less than 2K later the cooler gaskets so were probably already leaking. Now with 150K I hope that my high temp sealant on the new gaskets will provide a longer gasket life.

Thanks Graeme, cheers [emoji482]

The original gasket part numbers have recently been superseded, hopefully due to being made from a better heat resistant material.
