Blown Turbo or Stuck EGR Valve

[dazzling2865]

Well after 2 more days in garage they seem at a loss. Not engine codes and therfore I am strongly thinking head gasket or head but as they saying it's intermittent (can run for hours with loads of white smoke and then hours with. Any ideas people? Thanks

more likely to be an injector sticking open.

Thanks. Did I read somewhere about £1200 for a new injector? I'm loathed to pay after replacing the turbo for the same fault.

send them to diesel bob or take them to a diesel place to have them tested.

Get the injector trim codes read.
Basically every injector runs within a set of parameters, and the ecu can correct the fuelling within these parameters, once they get to their limit of adjustment the ecu can go no further and you get running/smoke problems, any indy code reader should be able to do this, literally a few minutes work sitting in the drivers seat.
Again if you do some research getting the common rail injectors tested is not as easy as people think, Ive read quite a few posts on different forums where people have done just that, got them back with a clean bill of health and problem still there, then spent **** loads more money fixing stuff that didnt need fixing only to replace the injector/s with new ones and faults go away!
I would find a good specialist as they are bound to have seen this problem before.
I have been saying for a few years now that as diesels get to clever the way to cheap motoring is naturally aspirated petrol engines.
Euro6 diesels are way way more complicated

A big thank you. I am going to call the garage this afternoon as seems I will have to pull out of there. No idea what I do with the £1500 turbo that has been needlessly fitted.

Small claims?

Proving anything against the garage is going to be almost impossible.

Well over 3 weeks since I first took my car into the garage (and apart from having it back for 3 days) they still have it and admit they are at a loss. Getting p'd off now. Fault comes and goes (some is definately white and oil/diesel smell).


I am reluctant to just drive the car away to another garage (and a new bill) when they have virtually agreed with me that the turbo was likely not the original culprit. They never return my calls and I had to turn up today unannounced and now they promising a head pressure test (but it's not losing water or oil in water/water in oil) so I am starting to believe from a 3rd party what I hear that it's overfuelling (stuck injector?). Garage say not possible as no fault codes BUT does this show up as a fault code?


Worst case I ask them to put my old turbo back on, refund me £800 and then use this towards my next bill. As I have the old turbo is there anything I can look at? No play in the impeller as far as I can see and turns freely.


Thanks people!
