I wonder if anyone can help please?
I bought a '52 Kangoo dci70 van on Monday and it suddenly lost all power by Wednesday. Its now in my local garage who diagnosed a faulty exhaust gas regulator. They fitted it and its exactly the same. Now they say its the MAF thingy or the turbo.
I'm a little cross because they're giving me the line that its the EGR ...AND one of the others. I find this difficult to accept really and wonder if anyone has a better idea of what's wrong?
Its low mileage 42k and its under warranty but I'm off the road.
It was also blowing out masses of black smoke from the exhaust.
Thanks in advance for your thoughts/opinions

On these DCi engines, the EGR can fail and take the turbo with it...
"If it sticks in the closed position the exhaust gas temperature will rise causing a) the turbo bearings to fail and b) engine oil into the induction system. This will cause the engine to go on running until it has consumed all its oil and then it will go bang."
New EGR, new turbo, and oil change might be the answer - which might cost rather a lot of money.

How do they then explain that the turbo does not fail when you run the engine at full throttle;the EGR valve is closed at full throttle and the turbo is at it's hottest??
|
|
Because the engine doesn't generally run at constant full throttle? I don't understand the finer points of these engines, I just remembered that it's a common problem on Renault DCi's, and copied the quote from the CBC section of this website.

It's more likely to cause concerns,especially smoke,if stuck open!!!

Hope you got this from a dealer....should be his problem.

Thanks for your replies so far.
Thing is, yes I got it from a dealer but he's based 30 miles away and I couldn't get it back to him so he agreed to let my local garage do the work (fair enough I thought). ]
However, the £150 plus for the EGV will now be on top of the cost of the extra part (which I suspect will be the turbo).
I'm just keeping my fingers crossed that they'll honour their guarantee and just let my local garage carry out the work.

UPDATE:
Well, as I suspected, the turbo was in bits. The local garage said he found a ridiculous amount of carbon inside the ports but couldn't clean everything without taking the head off. So he's done his best in situ and changed the oil & filter too.
Will this now be ok?

Will this now be ok?
Only time will tell. As long as it seems to be working now, and the EGR valve continues working correctly, I can't imagine it'll cause any more problems in the short-term. Give it an Italian tune-up (drive it VERY hard for about 15 mins) - can't do any harm to clean a bit more crud out of the engine.

|
And all the carbon came from an EGR valve stuck OPEN not a stuck closed one!!!!
|
No wonder it was so badly carboned up then.
