The clip is there just to hold the hose on the throttle body. The seals are inside the hose and it is them that start leaking and causing issues Neil.

Thanks Kevin
Is it right you cannot just replace the seal? You would have to buy the whole plastic unit? ..... and maybe the sensor too?

I could only see one green coloured seal and a sensor ... I think its a temperature sensor but unsure 2011 TDV8 4.4 Vogue SE

Yes mate, you have to buy the whole hose. I was lucky and had mine changed under warranty.

So you cant just buy the plastic angled fitting with the sensor in it? You have to buy the hose as well?

Seems ridiculous if it's only the seal that has gone
Welcome to RR I suppose

I have read that some members try PTFE to try and getter a better seal

Are you sure the seal is leaking? I had mine off and just cleaned the seal and the surface on the TB and it seemed fine and the seal was intact with no apparent wear or damage. I'm sure some PTFE would be a reasonable fix as well. You would assume it would be a flexible part secured by a jubilee clip like the rest of the connectors in the system unless it's designed blow off in some over boost situation? 2012 TDV8 Vogue (L322)

Mine was more oily on the end of the hose than your photo, but mine is bone dry now.
Part number is LR022663 but not cheap at £180ish!!

The connection to the throttle body was very loose and the retaining clip pretty much dropped out. There was a lot of oily residue in the hose and on the inside and outside of the plastic elbow connector (don't actually know what it's called )

I've had a couple of short journeys today with no warning lights so I'm feeling a bit more optimistic
Thanks for all your help guys ... much appreciated 2011 TDV8 4.4 Vogue SE

From tour earlier post I reckon you have been doing too many short journeys. The 4.4 tdv8 needs to get nice and hot on a long run. Short blasts will soon fill a DPF. Short journeys are a killer for a 4.4 Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

HEEEEEEEEEELP!
Bloody DPF FULL AMBER WARNING LIGHT is back on

Here's what I have tried so far:
Taken the car for 3 MOTORWAY RUNS of 60 - 70 miles EACH trip this week. Ran the car at 3000+ RPM. During each run the DPF warning light went out only to come back on the next day. So now I have done it 3 times I am beginning to think another trip will not make a difference. ....... apart from emptying the fuel tank

Inspected the 4 short hoses ..... no leaks

Removed, cleaned & tightened throttle body hose to TB

Car is going for a fault code analysis next week but not sure if I should just park it up til then ?????
Is there anything else worth looking at before I take it to the garage?

Could the DPF sensor itself be goosed? 2011 TDV8 4.4 Vogue SE

Not sure if revving it to 3krpm is going to help and it may actually prevent the proper regen process taking place. Until you get the codes read it's not helpful to speculate. 2012 TDV8 Vogue (L322)

I suspect you have a leak, or possibly the Inlet manifold is cracked. It's c. £1600 to replace one. They were known to be too flimsy to withstand the pressure of 2 turbos and have since been beefed up.

1. Get a HIGH pressure smoke test done. It must be high pressure as small leaks and cracks won't show up otherwise.
2. Get an Iid tool and see if you are regenning normally. It will save you money and hassle as you can reset faults etc to make it run if in extremis and away from home.

I doubt very much if a small leak will cause this. Likely a run up the M-Way is just doing a passive regen and some other system or sensor fault is stopping it going into an active regen and this will only be revealed when you get it scanned. IMO and IME L322 ownership is an unrealistic proposition without a GAP IID tool. 2012 TDV8 Vogue (L322)

Henshall Engineering will find it and fix it quicker than you think. Family friend had same issue. James Henshall reset everything (don't ask me how, I don't know) and its now good as gold.
James checked everything.

Regens work best between 40-60mph in Drive. Ideally using Cruise Control.
Speeding up, braking and revving the engine can halt a regen.
It needs calm consistent gentle pootling along at >37mph.

That aside, it really sounds like a leak. High Pressure smoke test is vital. Must be high pressure.

An intake leak big enough to cause excess soot via overfueling would throw an engine fault which is easier to identify with a fault scan than a high pressure smoke test IMO. Getting fault scan is the first and main priority. 2012 TDV8 Vogue (L322)
