DPF full turbo problems?

Greetings all

A first post and a sorry tale.

I've had the 4.4 TDV8 for about a year now with no real problems until it went into limp mode on Sunday at motorway speeds saying DPF full Visit Dealer.

I took for a DPF clean at an indie today and when they have pulled the sensor to allow injection of cleaning fluid it has come out dripping in oil. They have suggested one or both turbo's are on their way out.

They had also diagnosed leakiing air inlet hose as potential cause of DPF probelm.

Has anyone any experience of this and is it likely they are correct about the turbo's?

Any advice greatfully received,

Tom

Doesn't sound good. I'd take it to a specialist for their assessment if it were me. Henshalls Enginnering nr you Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

How many miles, is it using oil and what’s the service history? An intake air leak will cause the DPF to fill up as it will run rich. Oil in the DPF may be just from the 2nd turbo if it hasn’t had the drain mod. As Rob says get a specialist to look at it. Not unknown for turbo’s to fail but not common on these engines unless they have been abused or neglected. 2012 TDV8 Vogue (L322)

Hi, thanks both for taking the time to reply.

Car is on 118000 miles and full LR service history up to about 97000 miles with oil and filter done by local garage at about 110000 miles.

The short hoses onto the donut where changed about a year ago when I bought the car and the hose onto the throttle body (I think) is being changed tomorrow so it has been leaking air.

Sounds like a trip to a specialist is on the cards - I've not driven a car with my fingers and toes crossed since I was an Alfa owner.

do you have an IID gap tool diagnostic? you can use it to force a DPF regen, (in service menu) and that might clear it. you might also have the common exhaust sensor failure (p0040d) which means the DPF cycle wont trigger, because the sensor sees it 'not hot' and thus cycle wont happen. dont take this as gospel, but this was my issue, and with help of tool, i got mine regen'ed, and its working fine now.
as for turbo drain mod... there is a section/thread on here explaining it, and its possible to see if its been done. you should also periodically floor you accelerator pedal, to operate the 2nd turbo, and shortl after, look out rear mirror to see if you get any white smoke. (on motorway feed-in road is safest)

There's well documented DPF issues and the usual culprits on this this forum for the 4.4 TDV8.

All these jobs you can do without spending any money and seem to permanently resolve the DPF filling issue for many:

1. Firstly, sounds like the MAP sensor you reference. It gets gunked up every few thousand miles on most cars and needs cleaning, otherwise it is susceptible to sending wrong readings to the ECU, leading to too much soot in the exhaust or running rich, causing the DPF to fill. Maybe add it to your maintenance schedule - it's a VERY common cause. Allow time for a couple of DPF regens (aka do a good 20 miles on a motorway for no reason if you have to)

2. Conscious you're getting this done but this is a very common cause: The union from the charge hose to the throttle body on the inlet manifold is prone to the double lip seal failing (due to poor design). Loads on this forum about it but if you look at the top of the engine, it's the plastic bit with a metal clip around it attaching it to the throttle body. It only takes a few minutes to remove and have a look. If there's intake gunk in that vicinity or on the throttle plates (you'll see them when it's removed), it's a good sign it's this pipe. It's very expensive for what it is (£170) but this often permanently fixes the issue of the gunk in the intake and DPF filling for many members on this forum. My seal is on the verge of failing and before replacement, I am trialling a wrap of gas spec PTFE (which costs 40p) to see if it will re-seal and will report back when I've done a few thousand miles.

3. Check every hose connecting the inlet manifold. Have a good feel for seepage. Also look at the top 2 charged air hoses on top of the engine bay - I once had a split in one on another vehicle which was nearly impossible to notice until I took the hose off and had a look with a torch

4. You can check the turbo hoses relatively easily on this engine. The left side turbo lower hose can be inspected easily by just pulling out the left airbox (removing the M8 nut on the glowplug assembly first). The other turbo is also pretty straightforward to check visually.

Once you've had a good inspection yourself for the common issues, I'd then look at spending money on further diagnosis, such as a smoke tester or the exhaust gas sensor (not expensive but a pig to get to) which is what I would think about next. 2015 Range Rover Autobiography 4.4 SDV8
