ok guys.... got a td5 that runs ruff when started, has a slight miss every so often, and doesnt seem to be as pokey as my bro's......
so I thought  I better check the loom into the ecu as suggested on here and sure enough, loads of oil in the plug. :x 
So, where do I go from here, what is the best way to clean this lot up, and how do  Istop it again, am I gonna need a new ECU ( I do hope not).
Cheers
