Hi All,

Had a problem with my TD4 freelander, low on power and black smoke on acceleration. Tracked down to a split hose (the one on the top left hand side of the engine going to the front).

All well and I'm picking one up today.

However, there's a good amount of black oil in the pipe, enough to coat your finger, is this normal? You can see where it has been spitting out of the split hose. Sounds a big dodgy to me.

I've about 3 weeks warranty left, I'm not fussed about the hose but if the turbo pops then I'll have to do something before the warranty expires.

Thanks for any help!

Some oil in pipe is normal but black smoke is not. Replace pipe and check smoke and performance. Black smoke could have other origins not just turbo.
You don't say how many miles on car and who warranty is off. If it's a 2nd hand dealer I think you may have trouble proving your turbo is faulty as they will be reluctant to sort it (cost).

That's good to know then, will see how it is with new hoses. Thanks.

if you can afford get the silicone pipe from DPH

Replacing the split pipe should cure the black smoke, BMW crankcase vent mod should cure the oil in the pipe. Clean and disable, or bypass the EGR valve, inlet manifold may also need a clean. All covered many times, a search will bring the threads up.

Well darn. I replaced both top hoses and it's still doing the same thing! Thought I'd sorted it when I found the hole, bugger!

Any thoughts on what else it could be? Is there a way of checking the EGR valve? I did pull lots of black gunk out of it..

There is a hole in the left hand corrugated intake pipe, but as it's going into the airbox (I think) it shouldn't cause any issues than slightly warm air.

I'm picking up a EGR bypass kit today and while doing that I'll clean the inlet manifold. Hopefully that'll sort it.

Odd that changing the pipes didn't help, it would be the ones connecting to the turbo would it? Wouldn't that cause different issues?

When you say lack of power? a split turbo hose would be a serious lack of power. So I'm reading that changing the hose hasn't solved the lack of power.
As said, whilst you are at it change crankcase filter and turbo vent filter.

Did turbo change on a 2003 TD4 put it all back together slight overfueling (Black smoke) and slight turbo whistle, go back over all turbo piping, clip on turbo to intercooler worn allowing it to loosen. new clip cured it.
You never know worth checking

Thanks for the help guys, after giving it a good run out the black smoke has pretty much gone now,look, must've been some crap left in the system.

Got the egr bypass on order and will do the breather mod and intake clean while I'm at it. Will do a search for other preemptive mods too.

haha. Yes indeedy. I drove 30 smokey gitless amigoed miles to get my new hose, fitted it in the dealers car park, used their loo to clean up the amazing amount of black oil, and then started it and was happy to have power back and the light out, ...Until i stamped my foot hard down and saw tons of black smoke billowing out. Well I thought about it and realised there was a ton of crap in he pipe I had removed so presumably elsewhere as well, and just kept my foot hard down and eventually it stopped.
