Xc60 lack of response when accelerating

[Ross5080]

Hi guys hope someone can help:
Details of vehicle: 2009 xc60 2.4 d5 edrive 76000miles.

Started car at 7pm felt very un responsive, after 5mins driving car was accelerating perfect. Drove for 20 mins all perfect, short stop for 30mins again started fine but again lack of acceleration, but again cleared within 2 mins and drove 30km all fine with full power in all gears. Came home and turned off and tried again but again lack of power for maybe 30 sec, and perfect after that. No faults or warning on dash I am wondering is it dirty fuel as I filled up in a cheap petrol station last Thursday. I put dipatane into fuel tank just in case it's dirty fuel.Any suggestions or help would be greatly appreciated. Regards Ross.

Follow the Volvo handbook instructions for your car and use good quality fuel and do not use additives in the diesel.

The fuel filter should take out the dirt if there is some, but there have been a lot of issues in recent years with the bio element growing micro organisms that block the fuel filter and that is more likely to be the problem. especially with poor quality diesel. So take a look at the fuel filter and go from there.

Good advice from Roy above.
I had similar symptoms on my 2009 V70 D5, did the service and changed fuel filter. Never had this problem again.
Change the fuel filter ASAP.

Will do it first thing tomorrow and will let you both know, thanks for all your help.Ross

Diesel bug is an increasingly common problem with marine diesels. I have twin Volvo Pentas and had both tanks affected last winter. The black gloop which had to be removed was considerable and clogged up the fuel filters completely.
Never used to be a problem until the Bio element was increased in red diesel.
(which by the way is now taxed the same as Derv thanks to the EU) Its called fatty acid methyl ester (FAME). Many marine suppliers are having difficulty sourcing FAME free fuel hence the problem.
Now have to use 'Diesel Bug' additive in the fuel particularly over winter to prevent it forming.
It's not normally a problem in forecourts if there is a regular turnover of fuel.
Lets hope the problem doesn't migrate to automotive fuel with increasing bio elements.

Unfortunately, from what the specialist who looks after my cars says it already has. He's had to change the filter, clean the tank and fuel lines of a significant number of cars

My advice apart from the regular turnover and good quality is to keep the tank as full as possible all the time. That will reduce the amount of water in the tank formed by condensation especially in winter, and also reduce the amount of air available to stimulate bio organism growth.

Diesel unlike petrol does not produce fumes that fill the tank and exclude air of course.

Good advice. Boats left unused over winter are always brimmed for that very reason. If not using your car for an extended period I would adopt the same proceedure.

Changed fuel filter today and still the same, so went to my local mechanic and he plugged in his fault code reader and temperature sensor 1 fault came up and couldn't reset it. So my next port of call is to get the exact park no code and price a new sensor and replace it. Any ideas of price or exact part number please.

Catalyser or DPF temperature sensor in exhaust is most common temp sensors to fail

Sorry, when you said no fault messages I assumed you'd checked already. Was thinking what would cause the symptoms without generating a fault code which is why I suggested the fuel filter.
