2010 Ford Connect boost problem

[Heaveho]

Hi, as title, tonight on the way home on what is currently my very short commute, I got an check engine symbol accompanied by no boost. When I got home, in the time honoured fashion, I switched off, switched on again, didn't get a check engine symbol, and when I had a quick spin did have boost.

Anyone know about this? The van's a 110 Limited with variable vane turbo, 60k miles.

Oh well, I suppose it's progress! I went to put in on the ramps outside this morning so I could pull the inlet pipe off and check for play in the turbo. I had to rev it a bit to get it to drive up the ramps, after which there was a large stain of soot under the tailpipe. Upon restarting and revving it, lots of black smoke and oil dripping from the exhaust. Having seen that, and heard the noise as it comes on boost now, I didn't waste my time checking the turbo!

Looking for a reputable turbo supplier now.

Buy a new core off eBay, rebuild yourself, really easy.

Thanks, it's in tomorrow for a replacement turbo, smoke test for boost leaks and new oil feed pipe, as well as a mod to the rocker cover ( hopefully ) to stop the intercooler hard pipe breaking it's mounting and flapping in the breeze. I suspect a boost leak making the turbo to overspeed to be the cause of the failure. I'm going to send the original turbo to AET for a rebuild so that if it happens again, I'll have another to go straight on.

Well, bit of a result in the end. Split boost pipe on the manifold side. The smoke test didn't show it, it was only when driven that the split was opening up, and proved very difficult to spot in the workshop. Very deceptive noises when coming on boost, I would have sworn the vanes were touching the housing. New pipe and clips, new fixing for the other boost pipe which had snapped the threaded mount in the rocker cover, inlet pipe off to check for play in the shaft, exhaust off to check for oil, all seems well.

£160 all in. It was my birthday on the day I got it back, I was resigned to a bill of £1000 or more, so not a bad present in the end. It's running better than it has for the last couple of years, which makes me think the problem has been gradually getting worse over that time. Absolutely no smoke from the exhaust now, again something that was noticeable from a couple of years ago.
