Ive very sucessfully removed the useless Tire Pressure sensor reciver from an Exclusive C5... with the Lexia in the cars configuration menu.

As have I!

Another extra "deoptioned" by me are the pathetic auto wipers. Now they are just a nice controllable intermittent wipe.

One thing I would dearly love to do, but don't think is possible, is to bypass the ECU for the fuel gauge reading and just display what the tank sender unit is reading. I would then trust the gauge a lot more. I filled up the C5 just before the VAT went up and I've done about 170 miles since. The gauge is reading about 2/3rds full which would equate to about 34mpg - ridiculous.
As I get older I think a lot about the hereafter - I go into a room and then wonder what I'm here after.

Now I like the auto wipers, they are that bad on the Xantia...

Is the sensor VERY well stuck on the screen??

Hi guys sorry for butting in, (first post) but I'm very interested in this, I have a 2002 2.2 HDi C5 Exclusive and would like to disable this lot as well, is there anyone close by (Mid wales and willing to travel) who would be willing to do it?, for a fee of course.
Are there any legal implications?

I found that the auto wipers on my 607 go nuts unless I put rainex on the screen fairly regularly, or at least the bit where the sensor is
with rainex on the windscreen they work beautifully

I did mean just the software side of things by the way, ripping things off I can just about manage :twisted:

Hi.here's an update. I managed to configure the settings with lexia to no particulate filter present but after 350 miles the regen kicked in again and the car stutters again for about 10 miles until the regen stops. My question now is what components come into play that do not activate before the regen. The car runs perfectly befoe and after regen approx 350 miles.
Any ideas much appreciated!

Out of curiosity how do you know that it is the regen causing this? Regen is something which should only need to occur if the FAP is reaching relatively high levels of clogging. In an operation regime which includes a reasonable amount of high engine output carbon will be burnt off by normal exhaust temperature thus obviating the requirement for a regen.

One thing that does happen during a regen is that the EGR is disabled now what would happen if the EGR was only partially closed together with the modified injection regime used for regeneration I don't know but it is the only thing I can think of at the mo.

I don't find the Auto Wipe pathetic at all, in my view they work damn well both in terms of speed required to clear a given amount of water and in terms of amount of water before starting to wipe, I rarely have any need to have the wipers on anything but auto.
Just my take ;-)

Have you now actually removed the particulate filter and tied back the wires to the pressure sensor?

If you haven't then the filter will quickly build up a back pressure as it will (probably) no longer be dosed with Eolys and start to clog up..

I don't believe that just knocking out the filter and removing the sensor wires will work. Either the system will detect that the filter is blocked or that there is no filter either case will result in the engine going into LIMP mode.

Of course I MAY be wrong in which case I would really like to hear from somebody that can confirm that it works.

On the face of it if the Injection ECU can be fooled into thinking that the carbon level in the filter ie pressure drop is below a certain level it will not do a regen cycle, there is no requirement and the fact that the Eolys system ECU tries to inject Eolys from a dry tank every time fuel is added should not be problem. However it does appear that the Eolys ECU calculates the Cerium load in the filter based upon the amount of Eolys liquid it has injected, what if anything the Injection ECU does with this data I do'nt know.

I'm not asking that. What I'm asking is - after deactivating the presence of the FAP in the ECU has he now physically removed the FAP?

Hi, I haven't physically taken the filter out Or disconnected the sensors yet, as I was waiting to see if the regen cycle would operate or not after taking it off with . The fault occurs bang on 350 miles every time( stuttering) and can only be the regen that occurs on this cycle. I will check the eve valve as this sounds like the kind of component to give this problem and also the fact that it is meant to be disabled during regen . If it is partially open then maybe this could cause the stuttering. Just need to get access to it now a d will let you a know
