cress Posted December 30, 2007 Share Posted December 30, 2007 Hi again Glenn, Mines a 97 Tdi 300 XS Auto, now with 130000 on the clock. I have previously changed the cam belt etc in the past and I can honestly say I have had no problem at all from the EDC. Up tp yet it has served me well.

munkymush Posted December 30, 2007 Author Share Posted December 30, 2007 hi ivan .. thanks for the reply so its maybe me overreacting with my plans to swop? seems like they can be ok then ? regards glenn Quote Link to comment Share on other sites More sharing options...
sotal Posted December 31, 2007 Share Posted December 31, 2007 I think the majority have problems with the EDC but they're not major breakdown problems more like niggly faults. Mine is a 95 300tdi EDC with 105k on the clock, it has a couple of minor faults which I put down to the EDC system, having said that have you driven a Disco without EDC? They feel so slow the EDC really seems to perk things up a bit Quote Link to comment Share on other sites More sharing options...
Guy H Posted December 31, 2007 Share Posted December 31, 2007 and you can 'chip' the EDCs if you want a bit more. You can also get adjustable 'chips' so you can turn the power up & down depending on your mood (and how long you want the engine to last ;-) As has been said they can suffer from niggly faults but they are relatively easy to track down given the right tools & info.

Pete Attryde Posted December 31, 2007 Share Posted December 31, 2007 I changed mine to mechanical as I had several problems with the EDC on mine and it was cheaper (and less time consuming) to fit a second hand mechanical pump than it was to fix the EDC. I don't agree that a non-EDC disco feels sluggish in comparison I actually think that mine feels better now that it is non-EDC but I have tweeked the pump slightly so is not totally standard. Mine had 115,000ish on the clock when I changed the pump. I think if you are not having any problems, then you may as well leave it as it is. Pete.

munkymush Posted December 31, 2007 Author Share Posted December 31, 2007 i think ill leave it and see how it goes then ..the only other thing with it is theres a ticking or light buzzing noise coming from the injection pump with the ignition on+engine not running .. its there with the engine running too but obviously easier to notice with it it not running near my pump theres 2 multi connecters.. the large one with about 6 or 8 wires to it doesnt stop it if you disconnect it ... but when you disconnect the other one with 3 wires .....orange/blue or black stripe,white,+brown wires going to ........ black+white, brown,+black at pump .. ive never heard any injection pump tick or buzz b4 ..but ive never had one of these edc things ..do they make any noise in normal operation or is somat funny with this one ? ive just looked at the cd .. it shows a solenoid operated valve energization timing device at the bottom of pump..then 3 wires coming off one connection 2 going to the ecm +one going to the fuel temperature sender ... anyone got a clue if these would cause a buzzin or ticking ? apart from that its going fine B) Quote Link to comment Share on other sites More sharing options...
Pete Attryde Posted December 31, 2007 Share Posted December 31, 2007 mine used to buzz like that too! not sure but i think it is an EDC thing and nowt to worry about. Pete. Quote Link to comment Share on other sites More sharing options...

lynall Posted December 31, 2007 Share Posted December 31, 2007 The buzzing is normal My last 300 a 98 edc auto, the edc was okay over 50k sold with 100k on the clock was also chipped and it flew. Lynall Quote Link to comment Share on other sites More sharing options...

Oliver Posted January 2, 2008 Share Posted January 2, 2008 well thats me sorted out then ..keep the edc + "buzzing along " ha ha .. thanks to everyone for their help, much appreceated glenn Howdy all!! I am on my 3rd Tdi ex Japan where just about all were EDC. The buzzing is the 'inteligent injector' (#4) and the only part that really will give issues. One of mine went west and the replacement was NZ$500 + fitting. Having said that, not too common according to my LR specialist. EDC is good. No worries.
