thanks all for your helpful posts , all way to technical for me , the garage is having the car back on friday as they have said they want to look at the"NOx level." which they say is connected to the 5th injector , as for the smell its hard to describe but its very strong a bit like rotten eggs i can see people in the rear view mirror in the cars behind holding their noses and trying to fan the smell away , i have even had a woman approach me after i parked and complained about the awful smell as she had been driving behind me

car has been in the garage for a few weeks they have tested all the components and there nothing showing faults. The old injector is currently plugged into the wiring harness, which they have monitored it ( oscilloscope ) while running. The ECU does keep activating it.awaiting their final analysis

Good grief! A garage that actually uses a 'scope. I nearly fell off my chair!

Good grief! A garage that actually uses a 'scope. I nearly fell off my chair! I don't think cathode ray tubes are made any more. I was quite sad when I first read that. My postgraduate research was on looking at a new type of electron source for a CRT ! I guess laptops have replaced oscilloscopes nowadays. |

Oh heck no! 'scopes still in use for sure. It's just they've gone the same way as TVs -> TFT display etc. e.g. my current scope is about 3 inches front to back, compared to my first scope which would have been about 2ft front to back (and a lot heavier). You can use a laptop. You can use the "sound card" input to produce a very basic, low freq 'scope. You can even buy "proper scope type" adapters for PCs e.g: www.picotech.com/products/oscilloscopebut there's nothing quite like having a dedicated instrument on your desk, that just works and you trust. Both types have there place. I used to have access to a very fancy spectrum analyser and that effectively had a windows PC embedded in it. I was just surprised at the garage actually bothering to look @ the injector waveform. |

at a stale mate really , smokes with 5th injector in but doesnt with it unplugged ,thinking of unpugging it and going to have the performance of the dpf regulary checked until another solution hopefully arises ,hardly doing any miles at the moment due to lockdown and unemployement .

The Engine Management ECU calculates and keeps a rolling record of "DPF thermal degeneration". i.e. a figure of how efficient it thinks the DPF may be. I assume the DPF efficiency will get worse with time and the record held in the ECU will reflect this. I expect that will have some bearing (maybe or maybe not a major factor) on the DPF regeneration cycles.
If the DPF is changed, that record in the ECU should be reset. Likewise, if the ECU is changed, the record should be transferred from the old ECU to new, if possible.
If the DPF has been clean/changed (it's been cleaned), has that record been reset? (Needs diagnostic tools). It may or may not make a difference, but it's possibly something else to eliminate.

thanks SHCM , the garage told me it put the data into the ecu that it has been cleaned . He said he had conflicting data from the dpf pressure , they said thats why he wanted the correct data from a good dpf to compare it , he says he wasnt able to obtain this but in his opinion the dpf is ok for now.

I don't know where you live. just for info, I was fortunate to get to know a young mechanic who had a passion for doing extreme things and it was he who rebuilt my 1994 Rav4 using a 3SGTE engine and then modified it with a new Apexi FC ECU programmable; uprated turbo (I can't go on until the tears subside as I should never have given up on the car...just cos it got rusty) Anyway, the chap moved on to start his own garage in Edinburgh. He now rarely does run of the mill servicing etc on cars. He takes on more complex diagnostic work, fixing cars from dealers whose own mechanics can't discover problems. He must be good as he's busy all the time ! I did use his services a year ago to find an intermittent fault on my Volvo auto box which threw up a fault now and again preventing me from selecting gears...quite annoying. Traced to a damaged circuit board below the selector stick - took him 10 minutes - and explained by reckoning someone had spilt coffee down the works. Wisnae me !
Anyway, reading your thread post, I would imagine this is the sort of thing he'd relish.

thanks for that but im in wales , i did have a warning about the oxygen sensor p0137 but when i started the car the next day it had gone , dont know if this is relevant to the problems im having

Hi, Please could you let me know where I can find the good mechanic in Edinburgh, I have two Rav4's & both have problems that seem to be impossible to find the cause of! Our 2013 2.2L D4D Invincible has the same issue with smoke at intervals when warmed up suggesting something to do with the DPF regeneration ?? In main dealer right now trying to work out what is going on?? Cheers Saul |

He does a fair bit of work fixing cars for dealers who struggle to repair cars. I'd expect he has a few weeks work in hand though. |

stopped the smoke by disconnecting 5th injector not ideal but dont do many miles so dpf seems ok . i did have it cleaned originally so hopefully plenty of life left in the dpf

stopped the smoke by disconnecting 5th injector not ideal but dont do many miles so dpf seems ok . i did have it cleaned originally so hopefully plenty of life left in the dpf Just wanted to say my father has bent suffering from exactly the same issues. In short, car went into limp mode, he couldn't find the issue and I ran a quick diagnostic while visiting him with a cheap OBD2 scanner I had around. Clogged dpf, p2002 code and car into limp mode. He tried plenty of stuff and finally bought a new dpf and fitted it himself. Cleared the codes with my scanner as I taught him to do and the car seemed to be ok. However, the car was throwing white smoke quite frequently, very frequently, and a lot of it. He couldn't figure out why so he decided to disconnect the fifth injector and connect a spare one to fool the ECU and not get any codes. He Used the car for about 20k kilometres until we came again for a visit (we live abroad) and we borrowed the car. And here I am, in the middle of nowhere trying to get home with a car going into limp mode as I've been unlucky enough to experience the newly fitted pdf clogging again as anyone would have expected. I've removed that 6th injector that my father installed to fool the ECU and connected the fifth injector as it originally was but the car doesn't try to regenerate once it sees that the DPF is fully clogged, it just goes into limp mode. So I would strongly advise anyone with these problems not to disconnect the fifth injector to prevent the white smoke, or they might see themselves really far home with a car going into limp mode. I was going to try fooling the ECU myself to prevent the car going into limp mode and get home (it seems I got something from my father) by opening the circuit of the differential pression sensor, but after reading that PDF someone has posted (thanks, btw), it seems the ECU is gonna know I have opened the circuit after all it sounded too good to be truth, i know). No idea how I'm gonna get home like this, but I swear we're gonna take apart the whole car if we need when I get there. |
