Rav4 2011 D-Cat

It’s usual for new members to introduce themselves before launching into a question which no one can answer given you’ve put almost nothing about the sequence of events and importantly the age and model of the vehicle… There are several versions of the diesel engine for instance.

Hi sorry guys I am new here..did post an additional reply to this a day ago but has not appeared here,,so here I go again..
Basically filled up the car with petrol instead of diesel..car drove for about a mile and half...coughed..juddered..small cloud of black smoke came from exhaust ..and died
Took it to a local Toyota garage(with unprofessional staff)..charged me £700 for emptying the tank and replace fuel filter...but the car did not start so they came out with All 4 Injectors have gone..£1800 cost but No Guarantee that this is the only problem..Considering that they had charged me £125 for a Diagnosis...this was not acceptable..so towed the car (after a lot of trouble from the dealers) to an Injector specialist who identified 1 injector blown..replaced it but it still did not start!  Waiting for further investigation....any ideas? suggestions..possibilities?

I did similar several years ago though not a full tank.
Drove for about six or seven miles before the stuttering started and I realised what I had done. Called an emergency tank emptying service and chap duly arrived, pumped out the mixed fuel via the pump, emptied the filter and then flushed the system. Added a few litres of diesel and a fuel treatment [Can't remember what it was].
He said the only damage likely would be to the high pressure fuelpump due to the lack of lubrication from the petrol. I was his eighth call that day.
RAV now approaching 150K miles.
Was the system flushed out properly or did they simply empty the tank by means other than through the pump?

Running with petrol in the diesel robs the fuel pump and other parts of lubrication as it’s the diesel ( heavy oil ) that give the lubricatoon. Sometimes you get away with it sometimes not . I’ve only once heard of petrol buggering injectors and it was a complex diagnosis because from memory the only guaranteed fix was all four injectors . Tricky because replacing one at a time is labour expensive due to the bleeding process snd replacing all might mean your doing ones that were ok .

Perhaps a diesel specialist who can test the injectors would be better than a dealer who would more likely do them all . It’s a horrible situation and your certainly not the first.
I see you’ve tried an “ injector “ specialist does that mean a diesel specialist? I think there might be a difference. A dedicated diesel specialist would understand the complex pumps the injectors and every other component in the diesel system .

Dcat has a 5th injector primarily for regeneration purposes. I’ve had and still own a D catted car and they have the 5th injector as do all others. Your Toyota dealer should know this if they don’t you need to go elsewhere. It’s a somewhat complicated system but it works. 

It’s hard to imagine the problem is not related to the miss fuelling of your car. Reading through your posts you say Toyota charged you £700 to drain your tank and fit a new fuel filter which is an absurd amount of money given they didn’t even get the car running. 

I miss fuelled my old T180 ( Dcat) but realised what I had done so we dragged it to my mates garage where it took about 45 minutes to drain the tank and change the filter bleeding everything out as we went. The tank has its inlet on the nearside rear so we took off the hose then undid the tank straps and out it came. 45 minutes tops. 

Have a look at this thread.

Bit confused. Did you actually put in wrong fuel and tell the dealer such or did they tell you that the car had been misfuelled?

Thank you Charlie..
Spoke to Toyota who are trying to pass the blame on me now that I SAID it was misfuled i! I NEVER did...because I did NOT know...Had I known that it was misfueled I would never take it to Toyota..I rather pay £110 to AA who would do it. Also asked Toyota to show me their phone records as they claim to record all calls. Yes I have proof from the petrol station that I put DIESEL and not Petrol..showing the Pump Number, Nozzle Number and the price of Diesel@1.56 per litre. Checked the prices of other fuel stations on that day and they match with Diesel price and not petrol. Toyota also claimed that theryn emptied the tank, refitted a new Fuel filter and put some diesel...the car did not start so they asked me another sum of £1800 to change the injectors..but without any assurance that it would fix the problem. So took it to a injector specialist who found 1 injector faulty and replaced it. The car still did not start..white smoke came out form exhaust which has now turned it to black smoke.
I feel Toyota outwrightly cheated me...by giving wrong diagnosis, charging me £700 and returning  the car in terrible state(they had charged me £125 just for the diagnosis) Now they are saying they dont even have the records as I collected the car back from them. A manger called Luke was trying to be helpful and suggested if I take car back to them they will try to check it again in the new year. I am left with real sour taste in my mouth that such a reputable big garage would come down to this level. Someone who just looked at it and says most likely it is DPF some sort of fuel filtering system (not the ususal fuel filter I guess) which is about £4000 to replace. The car is worth around £3k! What an experience. Thank you all again.
