Hey folks,

Long time lurker - first time poster here.

My 2004 1.9d Doblo is having a few issues. Firstly it has two pending codes - P3E00 P & P0711. After some internet sleuthing I've ascetained that P3E00 is a crank sensor fault and the other is listed as a transmission pressure sensor. I've sourced a replacement crank sensor and had it up on jack stands today but couldn't access the clip to get the sensor changed and didn't have the correct slotted torq bits to get it out. Strangely though, I can't see that the car actually has a on ePER. Does anyone know if this code may be for something else? Has anyone had this combo of codes before and had any luck?

The car is also dumping a fair amount of black smoke when given the beans aka 3000+ - is it possible that the cranksensor issue could be causing this or is there something else going on?

Thanks for helping out a novice!

Just to add it has a fair amount of oil coming from where the rocker cover meets the block if that is also a relevant symptom
