Can you test the N276

[DrEvil]

Just wondering if there are tests to see if the N276 is ok? Either with VCDS or Multimeter?

I note that block 103, 2 has something relating to fuel pressure regulator, but can anyone explain what this is and what this should be reading?

If the n276 were faulty it would throw a code, fuel pressure regulation is critical any deviation beyond the narrow parameters throws instant DTC.
