egr cheater fitted, no probs there so thanks to who ever came up with that very simple idea!
changed the oil, which took only 25mins!! not like last time when i broke the actuator on the charger trying to get the oil filter out.managed to find a space inside for the cap to sit whilst i took the old filter out, and it came out easy...how weird is that!
also fitted the extension piece to the exhaust sensor so hopefully no more code 420!!! we shall see!!!
this is what it looks like

so touch wood!
