Hi,
Need some advise I have a 300tdi auto disco, and recently removed the egr valve. Once I'd done that however I found that if I accelerated too hard or if I stayed at a constant speed of say 75-80mph on the motorway the engine would cough and I'd get quite a lot of smoke out of the back and I would lose power untill I either took my foot of the accelerator or switched off and back on again then it would be fine for another mile or so and then do it again.
I decided that it might be something I'd done wrong with the egr so I reversed everything I'd done and now I've still got the smoking on the motorway and loss of power but I've also now got a very high pitched screaming when accelerating hard.
Anybody got any ideas as I'm pretty much at my witts end and about ready to chop the thing in
Thanks
Dean
