P1472 Volkswagen -

Question

hi guys, 2000 audi s4 2.7TT P1472 code is kicking my ass. I've changed out the N75 and charcoal canister already and still no luck with solving that problem. upon further research I'm led to believe there's a Short in the system my question is where do I start looking for a SHORT ?

Answer 1

P1472 Leak detection pump (LDP) tank ventalation system

Short in the system, with P1472 the short would either come from the fuel pump relay, or the fuel pump sending unit. more than anything replace the fuel pump relay.
