White smoke from exhaust

NeverEnough

If it drives fine and there are no error messages, put it in for an MOT and see if it passes or fails. I certainly wouldn't be paying £7K to repair an oldish Santa Fe, but I think it is highly unlikely that everything needs replacing if it is still performing reasonably and this garage are just looking at replacing absolutely everything. If it genuinely proves to be a crazy price issue to repair, after getting a few other quotes from other garages, try to MOT it and sell via webuyanycar.com or similar trade buyers, or part ex it with its full MOT -dealers usually just send part exes to auction anyway.

I used to use a huge breakers yard which covered all types of makes and parts for my cars over the years. Depending on where you are you might be lucky to find one.

It sounds like the engine has issues, whether its as bad as the garage says is anyone's guess.

If i were you i'd find a proper Diesel specialist workshops, and take it there for expert advice.
If you can't get recommendations for one from people you trust, ask some friendly local taxi or courier van owner drivers where they get their cars fixed, usually a good bet.

OP please ignore advice to keep on driving and see how it goes. Doesn't matter if there isn't a single warning on the dash, you have stinking, unburnt diesel pumping out of the exhaust, you don't need a code reader for that.
As above, get it checked out by someone who knows what they are talking about now, it may be relatively simple to fix and save the engine.

Hydrocarbons wouldn't produce white smoke

Unburnt diesel will - same as you get on start-up if one of your glow plugs is faulty.

It's quite unusual once an engine's warm, but some injector faults will cause it, and so can air entering the fuel system because you get some firing strokes where the mixture is just too weak to ignite.


eta: Colino, according to recent press, unburnt diesel coming out the exhaust is probably better than burnt diesel

White smoke and loosing coolant will be the head gasket, you would only get white Mayo in the oil if the breech in the gasket was between the oil and water on yours it sounds like it's between the water jacket and a cylinder so water is seeping into one of the bores and turning to steam then being fired out of the exhaust, low power on startup could be due to a pressure loss from the breech or water entering the cylinder making the charge more dense in one of them, when the engine warms a little and the gasket/cylinder head (I'm assuming it's ally as are most cars now) warms up it expands slightly and seals the breech a little

So here is the verdict...


New dpf with gasket and sensors
EGR values with gasket
Turbo with gaskets


Bad news

I'm feeling very skeptical towards this verdict.
With all of the above needing replaced i would expect the engine management light to be on.

I would be expecting a bill significantly less than £7k as well for the above.
Get a second opinion.

That's exactly what I thought. I've had no warnings lights on at all.


Thanks I think I will get a 2nd opinion

I can only guess that they've decided the turbo seals are failing and that's gunked up the EGR valve and contaminated the DPF but it looks more like they've fired the parts catalogue scatter-gun at it and just quoted for whatever hits.

Check for a local diesel specialist (one that actually rebuilds pumps rather than a "specialist" fitter!) and see what they think.
