Guest diesel_jim Posted February 14, 2007 Share Posted February 14, 2007 I'm looking at the EGR removal kits that Devon4x4 do, nice and shiny, but a bit spendy... What is exactly involved with the EGR removal on Td5's? just a case of blanking off the end of the pipe on the engine (i made a plate up on mine) or better off to remove everything associated with it? Do any electrics need removing? is the £40 odd needed from D4x4 worthwile? could i just cut some flat plate, weld a bit of pipe to it and be done? Or could i just remove the original EGR unit and run the air hacksaw around the inside of it and cut the giblets out of it? Thanks all!

BogMonster Posted February 14, 2007 Share Posted February 14, 2007 assuming the valve isn't permanently stuck open (and if it is, a bit of percussive maintenance with Special Tool No. 1 may repair it) all you need to do is block off the vacuum pipes at the modulator unit (usually fixed to drivers side wing). No vacuum = no valve operation Last one I did I pulled off the pipes (feed pipe to vacuum pump, and the pipe to the valve) pushed a 3/16" blind pop rivet into each connector, small cable tie around the outside to keep it a tight fit and cable tied the pipes out of the way. Total cost about £1.00 Quote Link to comment Share on other sites More sharing options...
JST Posted February 14, 2007 Share Posted February 14, 2007 i did the same as BM removed the pipes from the modulator and put an M4 bolt in them to stop carp going up there and job done, left the rest of the gubbins still attached but it cant open so doesnt work.

BogMonster Posted February 16, 2007 Share Posted February 16, 2007 Need to be blind rivets obviously, otherwise they ain't airtight! Quote Link to comment Share on other sites More sharing options...
Guest dew110CSW Posted February 16, 2007 Share Posted February 16, 2007 Can someone just explain to a thicko like me what an EGR is, and why it obviously isn't essential to the running of a TD5? Quote Link to comment Share on other sites More sharing options...
Pete Attryde Posted February 16, 2007 Share Posted February 16, 2007 An EGR is an Exhaust Gas Recirculation system that takes exhaust gas and under certain conditions feeds it back in to the inlet for environmental reasons. What tends to happen is that the valve fails and leads to exhaust gases continuously being recycled which is not good for performance. It also leads to the inlet manifold etc getting gummed up with nasty black stuff especially on older vehicles. They are fitted to some 300TDi's as well. Removing them (and cleaning up the mess left behind) can make a good improvement in vehicle performance. Hth Pete. Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted February 16, 2007 Share Posted February 16, 2007 And, apparently, it makes no difference to the MOT emissions so you don't need to worry on that score. Quote Link to comment Share on other sites More sharing options...
Pete Attryde Posted February 16, 2007 Share Posted February 16, 2007 On the MOT front mine (300TDi) has just flown through with no EGR and no CAT either. Pete. Quote Link to comment Share on other sites More sharing options...
