Car Forum / Land Rover Cars / October 2006TD5 emissions
Hi, My 1999 TD5 defender has just failed its MOT on emissions. I had put an additive in the fuel and disconnected the chip but it still failed. Does anyone have any other suggestions how to reduce the emissions, can you 'reset' the ecu? Could I remove the air filter? Clean the carbon off the EGR valve? Any help would be appreciated Cheers Tony >Hi, > >My 1999 TD5 defender has just failed its MOT on emissions.

If you mean an aftermarket performance device, then yes, you might need to disconnect it. >Does >anyone have any other suggestions how to reduce the emissions, can you >'reset' the ecu? Could I remove the air filter? Clean the carbon off the EGR >valve? Any help would be appreciated put it on a testbook and get it reset. Theoretically, this is supposed to happen regularly in the service schedule... I suspect that various dodges like removing the air filter are just likely to confuse the ECU even further. Of course, there's always the favourite "thrash the nuts off it for 5 minutes before testing it." The other thing that happens is dependant on your tester: run it at less than full revs.  SignatureAustin Shackles. www.ddol-las.net my opinions are just that "It is a characteristic of the human mind to hate the man one has injured" Tacitus (c.55 - c.117) Agricola, 45 >The other thing that happens is dependant on your tester: run it at less >than full revs. Best option is to fit very thick carpets !!
