Defender Puma EGR blanking - 4x4 Community Forum
Dunelandy is the guy that removed the gears, I think post #35 shows some pics. Reading the most recent threads, he still has no MIL light. This however is for the 2.4, not sure about the 2.2.
I've been following this closely for awhile now, as I don't have the money for a remap yet. At the moment I'm halfway through an experiment, which involves simply unplugging the EGR on shutdown and leaving it that way, once it's done the "chuka, chuka, chuka" clean cycle and is closed. So far in just under 3 weeks and 132 cycles no MIL light. Maybe I just got lucky, but it also seems to work for some of the members on the South African forum. I also have a spare EGR from the previous owner of my Puma, never did ask why he had a spare ! I've removed the gears, made sure it's closed and will try Dunelandy's idea after a month of running around with the current one unplugged. Plus it gives me a chance to pull the current one apart to check it's condition.
Oh yeah mine is also the 2.4, and the EGR was working fine before I unplugged it. Again like others have said, I just don't like the idea of pushing dirty exhaust gases back through the engine.
