For the 12,000 mile service, they recommend taking it off and cleaning it internally. I assume you can do that without draining the fuel tank?

Anyone know? Can you remove the fuel sedimenter without all the diesel from the tank pouring out? :?
seph234:
sorry cant help you with that question but im sure i read some where that it can become brittle and something on the sedimenter breaks off quite easily so be careful. if only i can remember where i read it(poor memory sorry) ](*,)
Wanderer:
The sedimenter being removed can start to syphon out the diesel.
Take care around the pipes going into the sedimenter. They can rust and allow air into the fuel system if disturbing them causes any pinholes.
Some people bypass the sedimenter altogether.

Hi Gord,
How long have you had the bigger tyres fitted? They will have raised your gearing by about 10% and this can make a huge difference to performance with a tdi engine in standard form. You might well find that there's nothing actually wrong at all and you just need a bit more power to pull the higher gearing.
gords:
I think (?) I would have noticed if the performance dropped that much after putting the tyres on. In fact, I seem to remember not noticing a huge difference!
The problem seems to have been gradual - but right at this moment it seems as though the car is constantly towing a whopping great big caravan :shock:
As I said previously, it struggles to 70mph on a flat motorway and the slightest hill or headwind can easily knock 10 - 20mph off :evil:
Coming back from Wales at the weekend, I drove most of the M40 with my foot flat to the floor - which equated to no more than 75mph!
I appreciate the tyres will have an effect, but I can't believe (yet) that it is the problem...
I shall drain the fuel sedimenter and clean the intercooler (and check the hoses) and see what effect that has. I also have a boost gauge coming...
