Peugeot Partner Teepee 1.6 Blue HDi 2016
First post so bear with me. I've had the, what now seems to be a common fault, Urea/Adblue fault scenario. I confess I haven't read all the posts - got to page 16ish and realised there were 41! so if I'm repeating what has been covered I apologise - so just want to chuck in my six penny worth.
At some point prior to my purchase of the car from a dealer (2019) the AdBlue cap had been replaced (blue cap with white insert). As a result of reading the initial entries of this thread, I cleaned the cap and then tried to blow/suck through it, I couldn't so I thought maybe it was blocked. I took the cap and prised out the insert then prised off the white cap. Inside there is a black moulding and an o ring (which seals the insert to the blue cap) and a white 'membrane' covering the opening to the tank. This membrane makes it IMPOSSIBLE for the insert to allow the tank to breathe! What is the point of that?
My thinking is FWIW is that the pump eventually starts to suck on a vacuum and eventually fails. (This hypothesis is discussed early on in the thread) I have fitted the blue cap back on the tank without the insert as a test and so far I have not had a fault. To be fair I've only done 60odd miles so far but will update if things change. Has anyone else forund the above issue with the cap?
