Diesel Algae ---- LP fuel pump death

Both LP fuel pumps failed on a BMW M47R Diesel engine in a Rover These cars have two LP pumps one in-tank and another under the hood --- LP under hood pump replaced after non-start, after replacement car ran fine but under hood pump was noisey with bubbles in fuel so in-tank pump was checked with current clamp ---- nothing in-tank pump was dead.

When the new in-tank pump it was swapped in one look.at the suction filter on the.pump and it was pretty obvious killed both pumps a bad case of diesel algae growth

I didn't know that was a thing.
Sure got a good coat of it on that filter.

You and your Rovers Andy you should know better,probably due to the age of the car/fuel supply system.

Really a classic case there are a lot of older Rovers owned by old retired geezers that do only say 2000 miles or less a year.. basically it comes down to cars need to be used

Have you seen any of these faults on a nissan x trail?P0235 turbocharger Boost sensor?P1525 ascd function, Pa00 Air fuel sensor 1. And P1614 Chain of ECM Immu?i think its a corrosion fault in the pcm,

No but I agree when you see apparently unconnected sensor codes corrosion issues are prime suspects

Unplugged ecu connectors, traces of corrosion on connector pins and going into ecu,,,,,other issues air leak in intercooler area,old turbo boost sensor resistance 6k ohms, new bosch tbps 1.6k ohmns,subsitute with vraible potentiometer 1.6k only fault po235 tbs fault, i think internel resistance too high in ecu, whatdo you think?
