Hi,
Re: P0405  EGR sensor A
I am hoping one of you good people can offer some advice.
I am, intermittently, getting the restricted performance warning and sometimes the yellow engine warning symbol, but it never goes into limp mode. Sometimes it goes days without either warning and when there might stay for a few seconds or all day. When the restricted performance warning is there accelerating hard more often than not clears it.
The following fault codes came up when plugged in:
P0405  EGR sensor.a
P1335 position sensor

I have tried Wynns diesel egr extreme cleaner and Revive Turbo/Egr Cleaner but not sorted.

Any advice on what the next step should be would be gratefully received.

Thanks in advance.
Guy
