Rav 4 T180 Won't Regenerate In Limp Mode Any Ideas

[Richard Wesson]

I have a 2007 Rav 4 T180 wihich is in limp mode with the p2002 fault code. I have only owned the car two months and it has full Toyota history last service 1200 miles ago, the week prior to me purchasing it for my Mrs, two weeks ago it went into limp mode and I had the code read and it was p2002, the garage regenerated the dpf and it was fine for two weeks then it went back into limp mode with the same vsc and engine management light on etc I have had the car in at my local Toyota garage today were they have told me that it now won't regenerate and subsequently needs replacing at a cost of £1900 after I had picked myself up of the floor and been and collected the car which is now not in limp mode but still has the engine light on for how much longer who knows any way I don't have a spare two grand to spend on replacing the dpf so just wondering what anybody else has done to rectify this, I've read a bit about having it removed and just wondering if anybody has removed one successfully from a rav or has any other solutions on fixing this without me selling both my kidneys

Hope someone can help me please

Is this on its original engine or has the engine been replaced due to oil consumption? Suspicions aroused.

Hi Kev thank you for the reply, as far as I can see from the history its looks like it has had the oil burning problem and the replacement engine from toyota in 2009, Im just going to ring the toyota garage in question to double check that this was done, there must be something else I can do with this issue without spending 2k !

[Richard Wesson]

I have spoken to the Toyota Garage that has carried out most of the cars servicing and in 2009 it had the oil burning problem and had the pistons or piston rings changed due to the oil burning but not a replacement engine, could this oil burning back in 2009 caused the dpf to get blocked up etc I think toyota customer relations is my next call as the local toyota garage is useless.com

Not sure if you have a copy of this TSB Richard but it may help your cause.

Thank you ever so much for that David, I have printed a copy off and just waiting for the service manager to give me a call back from the local Toyota Garage, fingers crossed !

Answer to your question is a deffo yes, Rich.........in 2009, I think the edict was to strip and rebuild, then superseded by the replacement engine TB,, as it was too much of a dealer cash cow to rebuild on site. You have a wee fight on yer hands mate.....

[Richard Wesson]

Thank you for coming back to me Kev and yes I agree for sure a fight on my hands , just waiting to see what the service manager has to say at the local Toyota Garage, he agreed with what I had to say and basically contridicted what his staff had told me yesterday , I await his call today, I am ready for the fight !

Has anyone had anything to do with removing these DPF filters ? I understand from reading that an Emulator has to be fitted has anyone done this or can shed any light on this as I need a back up plan if Toyota dont come up trumps

[anchorman]

You can have the DPF chemically treated at Toyota for £400 all in. It is important to use low ash oil and stay away from supermarket fuel if you cannot get the engine issue resolved or it will just exacerbate the problem.

[CharlieFarlie]

I answer to your question....

There is a place in Birmingham that specialises in the removal of DPF units form cars and remapping or fooling the ECU into acting in a normal way... Your Toyota has what is called a DPNR not a DPF which is in real terms similar but completely different..

Perhaps Anchorman can explain this better than me as I have only the basic working knowledge which may miss inform..

However I can tell you that it is not possible to fool or re map the Denso ECUs fitted to our cars. They are a very sophisticated unit and no one has yet managed to crack them and this is why in order to "chip" the cars for increased economy or more power a piggyback unit in the form of (For instance) the Lindop box has to be employed..

Sorry mate but you are stuck with that DPNR.......

Does your engine burn oil ? If not then the re build was successful and the oil burning issues associated with the 2AD engine may not be to blame..

If it is burning more oil than the prescribed ammount then as said above by Kev you have a fight on your hands and a complicated one at that.. Why ?

Well Toyota has paid a Dealer to rectify the engine and they have not I STRESS THAT THIS APPLY S ONLY IF YOU HAVE OIL BURNING PROBLEMS. So its up to that dealer to put things right..

Unless of course you can persuade Toyota to pay out again in the form of a replacement engine.. Fight ?? Oh yes and not one I would like to be in .......... Sorry .

i have a 2006 d4d 2.2 is the car fitted with a dpf filter?

[anchorman]

As Charlie says it is one up from a DPF, possibly two.

Hi,

I had an interesting problem some time ago with P2002 on a 2006 T180. I stumbled upon a cheap (No cost) cure, which could apply to others with this condition.

There are a couple small pipes at the back of the engine bay which supply a differential pressure sensor with a "view" of what's going on in the DPF. It seems that if one of the ports gets blocked down at the bottom end of a pipe, the sensor fails to receive the expected pressure. This triggers the dashboard warnings and produces code P2002.

Take a look at my post "RAV 4.3 T180 - Particulate Filter Or Not?" of Feb 28 2010.

This fault did not return once I had cleared it.

Happy RAV-ing

Toyota have a really comprehensive document to work through for P2002, which includes checking the pipework (it has been posted around these parts somewhere).

It may be worth confirming that they have worked through the procedure.

Thank you all for your help, The service manager at the local Toyota Garage has been on the phone and they are believe it or not going to replace the engine and the DPF under warranty ! Toyota have come up trumps in the end and the service manager I have been dealing with has been great very helpful and as you would expect for Toyota, my faith has been restored. Car in at the garage as we speak look forward to getting it back in a week or so :)
