  2. RR P38 4.6 2001 MOT Emissions (CO issue)

    It has failed its emissions test at MOT on CO excessivelyhigh something like about 5.5 on petrol (it was difficult last year to getthrough), HC were under the 200mark.

  7. TD6 delay in ports related to the VW emissions scandal?

    General Chatter
    A thought occurred to me as I read that VW/Audi has just been busted by the EPA for installing defeat software in their diesel TDI ECUs to spoof US emissions tests, and that other as-yet unnamed manufacturers are being investigated for the same thing. Is it possible that TD6 vehicles that are...

  12. Emissions control connections

    Range Rover Mark II / P38
    HI All Aussie thor engines seem to have the unused airline connector in the inlet manifold as pictured. I was wondering how it was held in? I tried turning it gently and it turned, but didn't seem to unscrew. I am thinking this the perfect spot to mount the temperature sensor for my electric...

    I took my 1995 4.0 for it's MOT yesterday and although at the time it was running on petrol, the tester has obviously noticed the LPG system and performed an LPG test which means it's the non CAT test. The results though wouldn't have passed on the normal petrol test so I want to try and fix...

  19. Fuel Emissions Leaking?

    Range Rover Mark II / P38
    Hi, My check engine light has been on for ages. Upon reading it it informed me that the system used to contain the gasoline fumes within the vehicle (in the tank) is not working. This could mean that my filler cap is loose, but it's often on even when I tighten the cap up snug. Regardless, it...
