2015 Peugeot partner tepee ad blue/urea light/ in Peugeot garage, ad blue topped up/ codes cleared,(£120) told urea pump pressure low , need new tank/pump ! drove 3 miles lights back on .in second Peugeot garage near home
diagnostics/ codes cleared, told urea pump pressure low ,wants ad blue tank/pump at major expense to me.
Drove 3 miles and urea lights on . Stopped car / ad blue filler cap off/ cap is not ventilated!
left cap off / tissue in filler neck to allow air in/drove 80 miles ,no lights . Now removed O ring seal on fill point/refitted cap so as to allow air to enter ad blue tank and prevent a vacuum forming.
now 350 miles later no further urea warning lights on.
Thoughts are that as cap not allowing air into / tank/ and vacuum forming, making the urea pump struggle to deliver urea .I am sure Peugeot know of this . I have been lucky and found this before the urea pump damaged. any Peugeot owners paid for ad blue tank/pump replacement.
