Hi apologies I've been working alot so my car is still in the garage I get it back today they said it was the fuel filter, it was black and was full of sludge inside the filter and around the housing etc and looks like its never been changed. So they've stripped it all out cleaned it and said its running fine now, once I've drove it I will confirm that this has fixed it. Costing me £60 to have this work carried out. But it has full stamped history so I'm guessing you cant always trust when someone says it has full service history.

Well cars back and faults still there.... 😭 Does seem to drive a little better but past 3k revs it went into limp mode again.. Back to garage I guess

Just picked car up again said it needs parts pricing up and ordering said it looks like a fuel pressure sensor? Are these a big job or expensive??

An old thread I know, but my neighbour had an identical problem with his S40 diesel. The cause turned out to be contaminated (water) fuel. The following paragraphs explain it well;

Fuel tanks and other storage systems are common thriving places for aerobic and anaerobic bacteria given the right set of conditions. When left untreated it can lead to the development of dirty slime in the fuel which can clog the filters and strainers in the tank.

He changed the fuel filter and everything was fine for a few weeks, then the problem returned - filter blocked again.

Since oil and water in fuel doesn’t mix, these microbes grow in the fuel-water interface which is usually formed at the bottom of the tank.

The microbial growth in fuel is usually described as near to the appearance of “chocolate mousse.” At severe conditions, large mats of slime will develop and block the filters in the fuel storage system. One very common fungus that flourishes in fuel is Cladosporium Resinae or “clad.” It was first discovered in aviation where it caused large-scale problems before finally controlled.

Wynns are just one company that make a 'fuel biocide additive' that kills bacteria, algae and fungi & also prevents regrowth. Probably best to remove the tank and thoroughly flush it out as well. He spoke to a Volvo specialist who informed him that he had come across the problems scores of times with diesel Volvos. Hope this helps someone.
