2003 VW Jetta Tdi with a code that comes back as.....
17970 P1562 035
Quantity adjuster-N146
Upper limit stop value sporadic.
What does it mean and how do I fix it? Thank you ALL!
WOW, I guess nobody wants to help with this one? Is it that bad? Anything at all would help!
Have you got a Bentley manual for it? Have a look to see what the N146 component is, and perhaps that will point you in the right direction?
Sounds like it may be part of the injection pump?
