This has been coming up on mine the last few months with the same limp home mode coming on. It's the power train light. Had mine scanned and it said glow plugs or glow plug module. The glow plugs are fine though.
I also concurrently had a whooshing sound from in front of the dash like the blowers were on and, after a root around under the bonnet, it turns out I have a couple of leaks in the turbo system, one at the intake pipe and one at the intercooler outlet pipe which is split. Will be replacing these soon as I get cash for the parts. Hopefully that cures it.
Don't know if yours is the same though. Mechanic who scanned it said power train light could really be anything, even though it said glow plugs. Are there any other symptoms? Any strange noises? Any change in your mpg?
I took off that steel pipe that goes form the turbo to the intercooler and examined it closely but found no crack.
I also examined all the rubber and plastic hoses and connections on the turbo system and found a few things. The rubber hose that goes from the air cleaner box into the turbo is cracked at both ends, the end that connects to the tube being sliced almost clean off
Also the pipe which tees off this and connects to the engine to the right of the oil filler cap below the injectors (yellow arrow in pic below) looks like it has a couple of clips broken off it. It's being held loosely in place by a zip tie...
The other place I found a problem with was with the plastic outlet pipe (outlined red below) that runs from the intercooler outlet to the intake manifold. This has a split in the seam along the bottom of the pipe.
So would these two areas account for my turbo leak whooshing sounds like the blowers are on in the cabin type noises?
Are these pipes expensive to replace?
Also, all the pipes I inspected in the turbo system had a lot of oil in them. The areas of engine adjacent to the points where the pipes shown above were split were also covered in oil. Is it normal for there to be oil in this pipework? Doesn't seem right to me.
check the thick rubber air intake tube. mine had a split on the inside of the 90 degree bend, couldnt visually see it but when pushed my finger went straight in. made a sound like the blowers were coming on when giving some throttle.
Thanks mate, I'll give that a look in the morning.
When mine came on it was glow plugs and glow plug relay
Mine is still coming on every once in a while. Had it scanned properly yesterday and it said the same thing, glow plugs or glow plug relay. But I'm pretty sure I have a turbo leak somewhere as it's making a 'whooshing' sound under acceleration which sounds like it's coming from on top/in front of the dash. Mechanic said this could be causing the warning light. Also it's chucking out a bit more smoke than usual (it's a diesel), so would this mean it's burning more fuel? And would this too indicate a turbo leak?
Are there any 'usual suspect' areas where the turbo system develops leaks? It's a 1.6tdci
