code 17656 RESOLVED (bad ecu)
I have a 2002 alh throwing a
17656 code. Hard start and lack of power.
checked timing in vag-com and couldnt even find it on the graph
vertical straight yellow line only so it tells me its too far advanced.
Adjusted pump max retard and still cant get it down on the graph.
It does idle and sound a bit better
I noticed it has very fine air bubbles in the fuel return( not normal fuel line air)
checked timing fly,cam,pump and still not on graph
