Diesel Algae ---- LP fuel pump death was created by Andy.MacFadyen
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

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