    2008 DCAT - replacing DPF?

    Hope all goes well. Usually this cat sells for £580 - around £700. Noticed a while back that a couple of sellers on Ebay were at around £270 which was at odds with all other sellers - presumably this is the one you've ordered. The BM part number etc is correct so this is an incredible bargain!

    Techsream Codes and what to do

    On newer cars with clever electronics there are many issues associated with disconnecting batteries. For example on some automatics, if the battery is disconnected in any position other than P or N the electronics will stick in the inhibit mode when the battery is reconnected and the car won’t start until you go through a programming routine. Similarity some ECUs will go into a safe mode on disconnection and it’s then not just a simple case of reconnecting the battery. One of the positives of the 4.2 is that it’s 20 year old technology and things are pretty simple - there are no systems that require resetting when the battery is reconnected (you don’t even need to enter a radio code!) Car ECUs are self learning and when the battery is disconnected, stored values are lost and the ECU reverts to factory settings. The car may behave a little different for a short period whilst the ECU relearns.

    Only the 2nd set in the lower picture now available.

    Techsream Codes and what to do

    It's obviously your decision but I'd have a high degree of confidence that disconnecting the battery won't give any problems. In any event the day may come when the battery dies etc etc. If it's any comfort I had a 4.2 which came only with one non-original non-remote key. The remote keys I subsequently got were therefore clones of clones and there was never an issue in disconnecting the battery. However since you've shown that the immobiliser functions correctly with both keys, it wouldn't be out of order to disconnect the immobiliser light - it must be distracting to have a red flashing light when driving at night.

    Techsream Codes and what to do

    The common hack when you only have one key, not necessarily on Rav4's, and when it's difficult or expensive to clone an immobiliser chip, is to remove the chip from the key and stick it under the cowl near the ignition switch. You can then start the car with a plain key but there is no immobiliser protection and the immobiliser light may malfunction. You can test the function of the system and the chipped key by wrapping the head of the key in kitchen foil. In this state - it shouldn't start the car. This being the case - you then know that the immobiliser system is functioning normally. If you search on the internet - you'll find many examples of misbehaving immobiliser warning lights. The example below was solved by disconnecting the battery though I understand that this is something you don't wish to do. http://www.teoc.ws/community/topic/48812-engine-immobiliser-light-flashing/

    Disconnect the battery for a couple of hours. This will clean any memory and restore factory settings.

    What's the situation now with the immobiliser warning light?

    It's perfectly OK to disconnect the battery - I'm not aware of other circumstances which caused owners to have problems.

    The sets are correct as pictured - the edge binding is different on the two sets. (Would have helped if the passenger mat in the left hand set wasn't upside down!). The left hand set is listed as all Rav4's 2002 - 2006 and the rear mats do fit this model. The right hand set definitely fits the 3 door Rav 4.2, I had the same set in my 2001 4.2. The catalogue lists them as fitting all Ravs 1996 - 2002 but I don't have a way of checking if they fit the 4.1.

    I have two brand new and unused sets of Rav4.2 over-mats - both in black with black edge binding and with fittings. The first set (left picture) is for all models 2000-2005. The second (right picture) is specifically for the 3 door 4.2 model and has the scalloped cutouts on the front mats which avoid the raised section of the floor near the centre console - these are very difficult to obtain! Free to a good home - just the postage to pay (£6). Please message with which set you want and your email address - one set per person in fairness to all.

    Techsream Codes and what to do

    Depends on what you mean by programmed - there are two modes to programme. Firstly to programme the remote action of the key - a working key is required - doesn't need to be a remote but does need to have a correctly coded immobiliser chip (original or copy). It can be tedious programming the remote mode since there are time constraints between the various steps and it's easy to make mistakes. In addition there are various published methods for Rav4 key programming and it can be trial and error to find one that works. Programming will fail because of simple faults eg if the drivers door light switch doesn't work. There are different ways of coding the immobiliser chip of a new key - the easiest way is with a working key which is required in order to read the code and copy it to a new chip. Code B2799 relates to an immobiliser communication error and is the probable cause of the peculiar action of the immobiliser light. To ensure that the system is restored to factory settings - disconnect the battery for a couple of hours after deleting the codes.

    That's a good price since an aftermarket remote key is £30+ before cutting and programming. I guess it depends on the location of Timpsons - it would have to be a branch where you could get your car close by!

    I'd check first of all that there isn't simply deterioration with age and mileage. Wishbone bushes do soften and in particular the strut top mounts can float about quite a bit. Springs can sag and shock absorbers loose damping efficiency. Tyre brand can also affect handling. Powerflex for example do polyurathane wishbone bushes for some Ravs and as well as standard parts, there are uprated and lowered road springs available.

    2008 DCAT - replacing DPF?

    You can check for correct part numbers against your VIN at http://www.japan-parts.eu/toyota Check with BM regarding agents nearest to you. There is no need for any re-coding after replacing the cat.

    As an aside, I’m interested in the fact that the likes of Timpsons supplied a remote key - they would usually only supply a plain key with an immobiliser chip in the head. A remote from Toyota fully programmed would be around £150 - what do Timsons charge? Did they need access to the car to programme the remote?
