Sticking Turbo (I think)
Apologies in advance, but could do with a bit of advice from anyone. Picked up a new to us caravan last night which we're very pleased with (Piccy in my gallery), but on the way back I ran into a bit of trouble. Pulling up a hill on the motorway, the power started to drop away & significant black smoke came out of the back. As we were near a service station, I kept going & pulled in when I could.
I opened the bonnet & more black smoke was coming out from the gap between the engine & inner wing above the turbo. I turned off the engine & left it for 10mins.
When I restarted it the power was back to normal, but after a short while I got the ESF message on screen & the power dropped off & the smoke returned. We weren't too far from home so I kept going. Today been out in it again & it's back to normal, apart from one time when it felt 'flat' so I pulled in & restarted it. I had this symptom a while ago so I hosed down the turbo actuator with WD40 & it seamed to go away.
Another bit of background is that I had its 105000 mile service earlier this week, but the belts have already been done so they weren't needed, just the service bit.
I plugged in the faultmate before we went out this morning & got the following:
INTAKE AIR TEMPERATURE SENSOR 2 CIRCUIT HIGH INPUT -:P0098
GENERAL FAILURE INFORMATION - NO SUBTYPE INFORMATION. (INTERMITTENT)
GET SNAP SHOT DATA FOR THIS FAULT
FUEL PRESSURE SENSOR CIRCUIT A - EXCESSIVE VARIATION -:P120E

GET SNAP SHOT DATA FOR THIS FAULT
TURBO/SUPERCHARGER UNDERBOOST -:P0299
GENERAL FAILURE INFORMATION - NO SUBTYPE INFORMATION. (INTERMITTENT)

Am I heading towards a new turbo, or could it still be the actuator that's sticking, or something else?
Thanks in advance

Been looking at the Innotec turbo cleaning kit - is it worth a try, is it feasible to get the pipe off the exit side of the turbo without a major strip down, anyone tried it on a D3?
I think the black smoke by the Turbo needs investigating first - sounds like a joint or hose is going by the turbo - if that is leaking, then most of the faults you have listed would have cascaded.Mark.

Yep, you have a big hole somewhere which you need to find and fix.

Thanks chaps - guess it's got to e cheaper to fix than an a new turbo, but not quite sure how much access there is down there - it looked quite tight when I blanked off the egr valves.
Pardon my ignorance, but does thick black smoke indicate over fuelling, ie too little air getting in compared to the amount of diesel as opposed to oil leaking in via the turbo somewhere? Had a turbo seize on my last D2 & there wasn't the think black smoke when it went, just no power (stopped it before the engine 'fed itself to destruction')
Yep, black smoke is too much fuel for available air.Mark.

Thanks - don't know why I didn't think to start with the turbo connections - obvious when I read my original post now - smoke out = hole for it to come out of
Just had a quick look through the wheel arch (not taken the heat shield off) & I think I can see a black rubber pipe going to the inlet side of the turbo & it looks a bit oily on the outside - guess I start there & work towards the intercooler then.
Thanks again

Had a bit more of a look at it this evening, the short connecting hose from the top of the turbo looks ok, but following the hose from the front of the turbo that heads towards the front of the car has been rubbing on a plastic bracket (not quite sure what it is as it's very tightly crammed in a around there). It only looks like a small hole in the pipe, almost a pin-prick - anyone any idea if this could be the cause of the loss of power & black smoke or should I keep looking?
Thanks
Marcus
Is it on the inlet or outlet to the turbo? Inlet then it probably won't cause the smoke, but I would not want it to be there as it is theoretically possible to get foreign bodies in - water being the obvious, and pretty damaging!
If it is the outlet, then yes, it could well be it - under pressure - ~1.5Bar absolute at its peak - it will become a big hole!Mark.

I think it's the outlet of the turbo, it's difficult to see to be honest - I might try & loosen the plastic inner wing lining & see if I can get a better look at it.
Sounds like outlet, I think you're describing the turbo to intercooler hose, nearside of the car?
EDIT
Take the plastic trim off the bottom of the car next to the engine skid plate, 4 plastic clips, this should give you a better view as behind it is the intercooler inletAltox GSM FBH controller thread

Yep near side, sort of under the FBH - looks a pig to get out
Still I've got a bit more of an idea of where to look if it belches smoke next time I put the caravan on the back

@Landie71
If you do replace the awkward stubby pipe could you possibly do a "how to"? I'm thinking of replacing mine with silicone ones,i've seen the stubby one when freeing up my turbo actuator at the weekend and it looks like a complete b d to get at
i'm assuming the flow is as follows
1.Main intercooler pipe(Already replaced! The one thats known to split!!)goes down to one side of intercooler
2."s" shaped pipe goes from intercooler to turbo inlet?
3.The b d short stubby pipe comes from turbo outlet?

Happy to try & put something together, but after this evenings tinkering the stubby one doesn't look too bad to get to (famous last words eh?). I'm guessing that to free up the actuator you took off the heat shield that's held on with three nuts (with captive washers on)?
With that one jiggled out of the way, the next heat shield can be removed by taking out a couple of bolts & just easing out the two wires (might be pipes - can't quite remember but doesn't matter for now) out of their mounting above the heat shield & that one can also be jiggled out too - not sure of the proper technical term, but I just sort of 'jiggled ' them until they came out!
Finally next to the battery box is the top of another heat sheid, held in by one screw - that this out & the shield will lift up, it's got two locating spring pegs on the top of it so you need to be careful to make sure the springs come out as well.
With that lot out of the way the stuby pipe looks to have reasonable (relatively!) access. Mine's got a couple of jubilee clips on it which are accessible from the inner wing & with them undone & a bit more jiggling I recon it'd come out.
I'll take a few pictures & try & put something together though
Cheers
Marcus
Just read your post properly - last two lines say it all! Interesting reading"

Marcus,
Yes removed the 3 nuts and that heatshield wiggles out easy,then a pre bent coat hanger and loads of plus gas on the actuator gets it moving nicely
