Thanks for such quick response m8
Can go into slow-mo at any time even when ticking over, I think normally when warm.
Will splutter at any time in low revs, especially when cold end especially jst b4 MIL light comes on.
Although when its spluttering, seems to hava dead patch on the throttle I have tried woggling the peddle in all positions with no effect.
changed the filters when it first started doing this. have jst checked the derv filter but all seems well there
Used to get the water in filter light intermittently, but fixed that with tape around wires at sensor and think unrelated to this prob.
will hava look at both sensors in the mornin
still cant quite sus out the EGR not sure which pipe to pull for the click noise

?
