. Sorted them & fitted all back together & went for a spin. No difference what so ever

I'm afraid it does sound like the Turbo, can only really investigate further by physical checking.
Turbo wise, I'd recommend having a chat with Gary @ Alive Tuning. He knows Turbo's inside out and can probably help you sort out issues remotely. Hope that helps.  WeWillWinπ¬π§πΊπΈ

Have you pressure tested the intercooler? 2008 110 2.4 XS Utility (Hagrid)

Thanks for that Steve. I did pull of the pipe from the end of the turbo & give the shaft a wiggle. No play & the waste gate arm does park in the 90 degree position when switched off. When its running on tick over its pointing down. What I have noticed since I have posted is some soot arround one edge of the flange where it bolts on the manifold. God knows what the underside looks like 
Would something as simple as replacing the gasket cure my probs?? I got no heat sheild in place as it broke off & no cat so can see easier As for the intercooler..... No not had it tested. Hows one go about that?? Thanks for input so far Chris

Turbo gaskets have been known to warp I believe.
I'm not sure if you'd be able to visually see if it is or not but there is ways of checking. (A bit beyond my scope of engineering knowledge.) If there is soot in the area present, it does sound like a leak of gasses / pressure in the vicinity. I take it there is no cracks in the manifold anywhere you can see? WeWillWinπ¬π§πΊπΈ

Reading up about turbo starting to fail it seems just like mine
One thing is about oily crap from your exhaust. That would explain the soot etc on the front of my trailer last motor way run
Surly if the turbo has failed there would be no power at all?? I get no power after 2000 rpm. Have to remove it to have a look  Chris

Turbo and rpm are interlinked, a poor turbo will run I'm pretty sure but lacking power and boost.
Turbo should kick out max power around 2k rpm I think looking at rolling road graphs. WeWillWinπ¬π§πΊπΈ β½οΈπ’οΈβοΈπ§°πͺ |

Thanks for your input Steve
Seems I have some phone calls to make now Chris

I've asked Gary the owner of Alive tuning if he could maybe help you on this here.
I'm not sure if he will be able or not, depends how busy he may or may not be. Otherwise I'd definitely give him a call. They do recon and upgraded too last time I knew and may even take you original turbo from you. In the meantime. Hope all goes well for you, maybe just the gasket still. WeWillWinπ¬π§πΊπΈ

If you have a diagnostic tool (eg Nanocom) you can check if you're getting boost very easily. It may be the infamous VCV on the fuel pump, not the turbo.
If you have no boost the engine will be massively down on power and it is unlikely you'll get to 60mph at all. Failure of the turbo is quite often caused by the actuator harness becoming chafed where it is secured to the block. What position is the actuator arm in when the engine is stopped? |

I have a nanocom which I will rig up tomoz
I pulled apart the harness yesterday looking for faults to find the 2 fat orange wires feeding the turbo kinked to the point of nearing breaking. I rejoined them & thought bingo my prob will be fixed. Wrong I have changed the VCV valve which also solved nothing. I still have the old one though My truck refuses to carry out the injector learn so god knows if its part of the prob Like you say if the turbo was fully dead I doubt I would get to the end of the street The arm is parked at 90 degrees when engine off. It points down when on tick over Thanks Chris 2008 XS 110 2.4 Utility. Tonga Green 1953 Series 1 for restoration 1983 Mini Mayfair 2004 VW T5 Camper 2008 Diahatsu Sirion.

Why does it need injector learning have they been refurbed or replaced?
If so and not gone through the learn process then that may have a bearing on it. WeWillWinπ¬π§πΊπΈ β½οΈπ’οΈβοΈπ§°πͺ |

I'm working from memory so may be mistaken, but that doesn't sound quite as it should be. The actuator should park in mid position, so that sounds ok, but IIRC fully up is the minimum boost position and fully down is max boost. I wouldn't expect it to the fully down on tickover, but I'd have to check mine to be sure. I may have mixed the two positions up. If you can hook up a tool to see live boost pressures as you run, it might be insightful. When my harness failed, I was getting no movement of the actuator and it was parked at the minimal boost setting. With increased revs there was some boost (after all the turbo is still spinning) but very little. After I had repaired the harness, you can see the boost increase to max and be regulated there under appropriate driving conditions. What that max is will depend upon which remap you have, but typically it is likely to be around 2 atmospheres absolute pressure, so 2 bar or 28 psi. Some tools may not indicate absolute pressure, only relative, so may show 1 bar. You should however get an impression of what the turbo is doing. If it is overboosting it may be that the ECM is limiting performance to prevent damage, but I would expect to see some DTCs in this case. As far as the harness is concerned, it is worth checking for damage at every point where it is secured to anyuthing under the bonnet. When mine failed, I found shocking damage to the harnes to the extent that if the actuator hadn't failed when it did, I think a vehicle fire would have followed in a few miles when the main alternator-to-battery lead grounded out - you could just see copper through the insulation where it was chafing. Appallingly bad design and build quality from our friends in Solihull! |
