Can anyone advise what to do, my friends TD5 is making a lot of noise from the Fuel Pump at the rear. Can anyone suggest what this may be and what to do ?

it can also make a whining noise when it is drawing air in too
The VERY FIRST thing to do is to fit a new FUEL FILTER in the rear right wheel arch behind the wheel. Buy THREE fuel filters, and always carry a spare in the car and one on the shelf in your garage.
The TD5 pump makes a terrible noise quite abruptly when the filter needs to be changed.
Find out in the forum how to force the pump to run and purge the system after fitting a filter. This is a quick run-down
Put the IGN ON, and leave it on throughout this process. When the pump stops deck the throttle and let it up five times, and the pump will start again. Do this as many times as it takes for the pump to make less noise.

My friend filled up at Tesco then shortly after load noise from the pump. He's now ran the tank right down and filled up at BP, no noise anymore !!!!
Are these supermarkets selling crap fuel or what ????? makes you wonder !

Remember that the TD5 fuel filter is much "finer" than a normal filter and will start to block up a lot sooner, and on fuel than might pass a standard filter.
But surely supermarket fuel can't be THAT bad? Can it?
Maybe it can.

the only noticable difference is price

Tesco, Asda, Sainsbury's and the like don't own oil fields (maybe they do !!) and they certainley don't refine to make petrol and diesel, they get it from the likes of Texaco and BP, but they just operate on lower margins on the basis that many customers who go there to get fuel might go into their store and buy their food
BP etc have no interest in food sales, so arn't so bothered in being competitive !!
(but you all knew that anyway)

LOL, you can say that again - BP etc have lots of cash additives, the supermarkets don't - simple really !!
(I'm only being facetious, I knew what you mean't really)
Some additives in Diesel are as simple as one to reduce 'foaming, and another to reduce cold 'waxing' . . . but at WHAT price ??
Foaming = fill up slightly slower
Waxing = If it ever is a real problem in this country, add a small amount of petrol, say up to 5% with no detriment to performance or engine life etc.
(just waiting for Lidol and Aldi to start selling cheap fuel from Poland, I'll be in that que that's certain !!! )

Ok agree with you there but the fuel they're buying must be lower grade without adatives etc... Morrisons & a Few other Super Markets around here (Durham Area) 6 months ago caused absolute mayhem... 100's of people with Petrol Cars etc broke down due to a faulty batch of fuel (only sent to super markets) a number of people had to get the lamber sensor replaced in the exhaust.... No costs recovered from super markets.
Number of guys at work with diesels tell me Shell, BP Fuels etc have a noticable difference in performance too...

To be fair the TD5 seems to perform better on BP than anything else, however the 300 is such a tractor in comparison.. I cant tell the difference
Don't use a TD5 engine as a guide to what any other diesel might do on a given fuel.
The TD5 uses injection pressures about TEN TIMES what is usual, and so it deals with dodgy fuels a little better. In a TD5 you might not notice some change of fuel that was quite noticeable in a 2.5 NA, or a 200/300 tdi.

Yep, the fuel pump pumps the fuel at 4 BAR at the outlet of the 2nd stage upto the front end !! (that's approx 57psi) and the injector pressure into the cylinders in a TD5 is typically a whopping 1,500 BAR (that's a staggering 21,600 psi)
To put that into perspective, a car tyre is typically 26 - 30psi and a lorry is around 90 - 110psi
Don't EVER (not that you ever would) turn over the engine with a finger over the end of a TD5 injector nozzle, it will give you a very nice injection of neat Diesel which wouldn't do you much good, and could prove fatal if it got into your blood stream !!!!!!!!

take you,re fuel pump out, bit of a fiddly job but not bad. some clips holding the outside white casin on prize open and take off be carefull not to break anything flimsy. theirs a filter on the outer white casing also one inside a very fine one clean them refit prime job done worked a treat on mine. biggest headache getting at it
good luck
