Its the turbo. I drove it gingerly today, to try and get some more data, I had drawn the same conclusions as you about no boost what so ever. As soon as I pulled up on the drive I disconnected intake pipe to turbo and tried to spin it. It turned but didn't spin, and there was an noticable amount of oil, maybe just under a teaspoon, nicely coating the intake. I guess oil seal has gone. So I phoned ford and cancelled tomorrows appointment.
I almost have the turbo off, but there is one bolt I just can't get at, its the lower one need the oil return. Just can't get a socket or spanner on it, the oil return connector is in the way. Then the light went so now indoors.
I have already ordered a repair kit of ebay, £30 quid. I had read that all the kits are identical, and no point in paying closer to £50, for some.
Whilst attempting to take the turbo off I did note one of the heat shield bolts was missing, and the oil feed banjo only had one copper washer and no filter!
Me thinks I was sold a pup 18 months ago and have been lucky it didn't fail sooner.
I have already dropped the oil (plan on doing this twice), and it looks clean, no swarf that I can see. I will take oil filter out tomorrow, and check it for swarf.
A couple of questions,
1. The oil feed pipe is now disconnected from the turbo, and appears to "swing" around where ever it is fixed to at the other end. Is this OK, and where is the other end (I guess behind the DPF)!
2.I'm going to see what damage has been done to the compressor and turbine, if any (wishful thinking), and then decide wether or not to use repair kit. A new cartridge is £150 on ebay, anybody any experiences with these. I guess they are balanced.
3. Any advice on how to do the job, tips and tricks? i.e how to access the bolts that hold the turbo to the block.
4. How do you seperate the DPF and turbo? There is a clamp that I have undone, but the actual metal c-cup (cross section) clamp does not seem to want to slip one way or the other. Don't want to force it.
