Question about Renault Clio
My car was contaminated with dirty diesel. The fuel was taken out the car was cleaned of any contaminating fuel. A diagnostic was done and said we needed 2 new injectors they were put in that didnt help or make the car start. We had different people say different things in the end we had 4 brand new injectors put in and dialled in, new temperature sensor, the fuel pipes all checked, a new air filter, new diesel, the tank cleaned and now the car will start but has pure white smoke coming out and wont do anything,the car practically has new everything on it and has been tested by 4 different places and it says there is nothing wrong but OBVIOUSLY there is what could it be? I really need help we have spent so much money and the problems never ending! Anything suggestions please, i would be so grateful. Thank you :)
You failed to mention what the dirt in your diesel actually was? The fuel filter of a diesel system is so efficient most dirt contamination never reaches the important mechanical parts and small amounts of water or similar also will not be a threat...
White "smoke" could conceivably be steam from an internal coolant leak but if the coolant level hasn't fallen that is unlikely.
White "smoke" from a diesel engine is almost certainly unburned fuel. That means either so much is being injected it is failing to burn or something else is preventing proper combustion - or a combination of events.
I once had a truck in for repair that created so much white smoke the scenery completely disappeared after a few seconds. The fault was a blocked exhaust system. Once the exhaust system was functioning normally the engine started and ran normally...
There is a tendency for the modern vehicle technician to rely too heavily on electronic diagnosis and because it works a lot of the time they lose the habit of checking the basics even though best practice says the basics should be checked before any attempt at electronic diagnosis is made.
If the contamination was something volatile and the exhaust is fitted with a CAT and/or a DPF it is quite possible the CAT could be melted.
If that is the trouble the engine is still likely to smoke for a while but the previous performance should be restored.

You have fuel delivery issue, what they are will take a diesel engine service technician time to figure out.

You generally only get white fuel smoke from a diesel when one or more cylinders aren't firing. If it were injecting more fuel than can be burned into a cylinder that is firing you'd get black smoke. You can get gray smoke from a cylinder that is firing cold or late, but blue obnoxious smoke is more common with late injector pump timing. Dirty/failed injectors also generally make a rude blue smoke.
Run a can of Diesel Kleen through it. If you can't get it where you are call a local truck service and ask what they recommend for cleaning the pump.
Check and keep watch on the oil and coolant- white smoke from a warmed up diesel is usually coolant that is getting into the combustion chamber, typically from a failed head gasket or cracked head/block.
If you see any oil floating on the surface of the coolant, or if the oil starts to look milky, this motor must be serviced and the issue found or it won't last long.

White smoke: White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. If white smoke is present, check to see if the proper amount of antifreeze is inside the radiator and the overflow bottle. Also check to see if antifreeze has contaminated the engine oil. You can look at the engine oil dipstick, or look at the under side of the engine oil filler cap. If the oil is contaminated with antifreeze, it will have the appearance of a chocolate milkshake. Do not start the engine if the oil is contaminated with antifreeze, as serious internal engine damage can result.
It is also possible to be a engine problem you should immediate visit a car service.
