If a good long run doesn't clear it, I'd get it to a good Toyota dealer (or a diesel specialist) to check.
Modern diesels really need good long runs to clear out the soot and other rubbish that the emissions controls systems get clogged up with. It shouldn't be constantly regenerating the DPF - unless it only ever gets to do 200 yard school runs and half mile shopping trips. If the problem started up when the DPF was changed, maybe they messed something up. Based on your poor fuel consumption, I'd be suspecting a faulty injector.Īs an afterthought: Another thing that could squirt unburned fuel through the system is the car trying to run a DPF regen. If your techie has ruled out a blown gasket, the white smoke could be due to poor combustion due to injection timing, faulty injector(s) or maybe low compression in a cylinder resulting in the fuel passing right through. White smoke is generally either water getting into the combustion chambers (blown head gasket) or unburned atomised diesel fuel passing through the system. I also used Wynn EGR cleaner and diesel fuel additive at the service to try and clean the systems out (I have used them before with no smoke). I'm on the verge of having to take it in to the local Toyota dealer to be diagnosed and to have my bank account pillaged, so if anyone can help it would be massively appreciated.One other thing I have just thought of - the last two re-fuels have been with supermarket (Tesco) diesel. Can anyone suggest what the problem may be? Apart from the !Removed! smoke the car is running fine. They are scratching their heads as to what diagnostics they can do to identify the problem. He said it needed to go to a garage for diagnostics.I took the car to my local garage and explained all of the above. He had a quick look at the injectors and he could not hear or feel any tapping or misfiring. He also said the smoke smells of unburnt fuel. He did a CO test and there was none in the coolant, so he is of the opinion the gasket/seals are ok. The temperature is normal.I called the AA - the mechanic said the Oil and water levels are ok with no sign of water in Oil or Oil in water.
The fuel consumption is poor (I thought this was due to the hole in the exhaust but now maybe not.). I have no loss of power and no warning light. The smoke seems to be linked to when I accelerate. The amount coming out seems to be increasing, but I have noticed that if I rev the engine it clears it (before it starts smoking again). It mainly happens when the car is warmed up and if I run the revs either too high or too low (under 1500 or over 2000 eg if I'm in too low or too high a gear). Since then I have noticed white smoke coming from the exhaust. I have recently had a new exhaust fitted (DPF to rear) and a service done with oil/filters etc changed. Hi, I am hoping you could help me with a problem.
