Paddy1976 Posted November 2, 2021 Share Posted November 2, 2021 Hi all , my 2010 a4 tdi started to idle really rough, it's still driving 100% just the bad idle, I had it plugged in and code p106500 is coming up , problem is its only telling me its a fuel pressure regulator, when I Google it there are x2 regulators , one on the rail and one on the pump, has anyone else had this problem and what was the outcome , thanks in advance and thanks for the ad 🙂 Quote Link to comment Share on other sites More sharing options...

Paddy1976 Posted November 3, 2021 Author Share Posted November 3, 2021 So , got a fuel pressure regulator there today , hopefully it'll sort it , the guy said it came out of a 2013 2.0 tdi passat, says its exact same part , does anyone know if these just fit straight in or would they need coded in ?

Stevey Y Posted November 4, 2021 Share Posted November 4, 2021 Hi dont qote me but I think they are plug in and play if thats a whole rail you bought you only need the bit on the end, just get anew seal. Steve. Quote Link to comment Share on other sites More sharing options...
