    300tdi disco auto - Surging at Idle

    Any advice offered on my 300TDi Disco Automatic. I have rough/surging idle. :?: Very limited budget but would like to fix it.

    How bad is the surging is it dramatic or just slight? is it doing it in drive or neutral?

    Do you have a "rough " idle or "surging' idle as these can be seperate problems, generally a "surging" idle is an injector pump diaphram problem (diesal specialist required) "rough"plus"surging" idle is more indicitive of a fuel delivery problem, any thing from air ingress into the system (have you changed the fuel filter latley /run out of fuel, has work being done on the fuel system prior to the problem ) to a pump problem, have you cracked the fuel lines at the injectors to see if all cylinders feel equal also to bleed the lines.

    Had the same problem when I did my first Diesel Filter turned out I had air trapped in system? Did you do your own servicing?
