Renault Trafic 'FAP pipe'

Hi,



The DPF light came on last week and the SERV light came on a few seconds afterward. Van went into limp mode.

Went for a late night 60min blast on the motorway, constant revs, 70mph, but lights stayed on. After reading all the horror stories online, decided to bight the bullet and contact local dealer.



Saw them this morning. Apparently they 'Cleared FAP pipe' (word-for-word on invoice and FAP is french for DPF i've found).

Guy explains that it's a plastic/rubber pipe part of the layout and it had collapsed which was choking the system and triggering the sensor/lights/limp etc.

Filter itself is fine. There was only 22g of soot in filter which after 7 years and 65K miles was fine. Can go as bad as 90g I'm told.

They quoted £280 for a replacement 'pipe'. (which coincidentally is the price of a new DPF I find).

After checking with them that I'm not going to do damage if it re-occurs any time soon, I left it at that for now to do some of my own research). Just the £45 diagnosis paid.



Left dealer, no lights, van back to normal. Great I thought !

5 minutes later, lights returned and limp mode back.



I've been searching online for ages, trying to understand what part platsic/rubber pipe plays in an hot exhaust system! No joy.



Can anyone shed any light on what 'pipe' they are talking about?



Many thanks.
