Hello everyone! Well after doing alot of reasearch and trying different things I thought that I would share some of the things that I have been doing on my Navara and hope that this will solve alot of problems for you that I have already gone through...
Ok so what I have done to remove the factory CAT and DPF without having anymore warning lights white smoke etc..
I had a 3" DPF back exahust system installed and had no issues there but my fuel compsumption was terrible! So I had decided to go ahead and remove the whole lot. I started by punching out the CAT guts and had sucuess doing so but it didn't do much just blew a heap of smoke when it was doing a regen cycle so I jumped on here and seen that someone had unhooked their presure sensor to shut down the DPF, what a big F%&*%ing mistake that was.. DPF light came on (death light) I was driving fine for about 2 weeks then BANG limp mode.. I had tried everything it went into Nissan and they tried 5 regens to clear it without sucuess it was FULLY BLOCKED.. Just so you know a new DPF is about $2000 - $3000 F*%#K that. SO after towing my car from where I broke down to Nissan then back to my house I took off the DPF and cut it open removed the guts and got it welded back up for $20. Back to Nissan! Before I did this I asked the mechanic what can I do?! He bascially said the only way to clear the limop mode is to put a new DPF and master reset the computer... OK now finally some light at the end of the tunnel got me thinking to get out of it the cheap way because I need my ute for work is to remove the guts out of the damn thing and get the computer reset.. Ok all done car was working finally after a week off the road.. Not CAT no DPF. SO what I have done now is get a 3" dump pipe turbo back 3" pipe all the way through but I had to get a 3" resinator on the thing after a week it was so loud sounded like a monstor truck. I had to get the fittings made up that the old DPF had except the presure sensors. Reason being. The presure sensors did not need to be plumbed back in but just plumbed togeather so they read the same presure. I will get photos up of the mods done and now that I know people that can make all the bits and peices if you are interested in doing this to your car I can get you all the parts. Anyway I don't have a regen cycle anymore due to the fact that once the computer is reset thinking there is a new DPF with all the new piping in place it willl never read that it's full. No white smoke! So once you have done all your mods just take it to nissan straight away and get a computer reset should only cost you $80 i'd say. Not too sure how muich but mine was alot more costly. The reason I have posted this up is because this is the best way to eliminate any problems like how I had. I will be posting photos and more information on this post as there are too many to keep track of for mods. I hope this helps people out wish I had this post when I was in limp mode
