Hi again, Does anybody know what length the 2 6mm rubber pipes that run from dpf filter to a sensor housing should be?? Any advice would be much appreciated

My EML came on and Ford said the DPF pipes had split and they want £180!!! now thats alot of money for a split hose. From the posts above I'm going to have a look myself.

Now this was 2 weeks ago question is how long can I leave it before it has to be done? What impact does the split pipe have on the DPF?

thanks

If I remember correctly, neglecting the DPF alarm will eventually lead to the ECU preventing the car from starting. Or this may apply only to VW cars....

Take your car to a garage and ask them to replace the hoses w/ fuel or silicon hoses. Sometimes the original hose can be shortened by 1-2" so that the fractured part of the hose is removed.

Hi, seen this post and after crawling under the car this morning it appears I have the same issue with hose split through. I have not put on ramps yet but can anyone tell me length of hose needed and size as have seen some posts which say 6mm and some 7mm. When on ramps is it obviouse and accessible where the other end of pipe connects? Thanks.

My 2.2 has 8 mm hoses, length roughly 75 cm each. I guess that on ramps you will have great difficulty in reaching the pressure sensor, provided that it is in the same location as in 2.2.

Usually there is a little slack in the hoses. You can remove the deteriorated part at the DPF end (5 cm) and reconnect the old hoses.

A few things:

  • There are two hoses; what happens depends on which hose is split. If one is split, it will tend to regen too frequently, if the other is split, too infrequently. Either could result in high fuel consumption.
  • There is no point in asking where the hoses go, the diameter and length of the pipes, how easy it is to do, unless you state which engine you have. The installations will be different on the 2.2 from the 2 litre, different again from the 1.8 and even post-FL might be different from a pre-facelift engine.
  • I've seen one post that suggested the two pipes were of different diameter (6 and 7 mm); I think this was a pre-FL 2 litre, but I'm guessing there. If so, it would have been presumably so that you didn't interchange the connection of the two pipes (although, if so, you might have expected more difference than that, because, with a bit of determination and some Fairy liquid and a Jubilee clip, you could still interchange those connections).

These things get hot, particularly at the exhaust end, and if you've got the option of silicone, rather than rubber, that would be likely to survive the temperature better. If you go to a Motor Factor for the hose, they ought (note: ought!) to be able to recommend suitable hose for you, if you give them the car details.

Had a DTC the other day P2002 the other day and today I got a chance to have a look and see if it was the rubber hoses or not. One is ok but the other is well and truly knackered, but I've managed to do a temp fix for now until I get some silicone hose tomorrow. Only costs a couple of pounds so why pay Ford ten times more!

One thing I am sure of is none of them will survive and they will all go as the Fords stuff has,but if it makes you feel better,pay hundred quid at Fords.
No sweat, of course I myself also would not got to the stealer to have it replaced...just thought that maybe 85 deg might not be enough.

Checked mine on saturday and think, even after 7 yrs they are still fine. And I saw that there is about 10 cm of metal tube before the rubber begins, maybe this also reduces temperatures enough to not destroy the 85 deg hoses.
