I'm having some problems with a 2.0 tdi 170hp at the moment, it's a PD engine, and to take things to the next level of difficulty, it's a 16v.
Started by a quick check of channel 13, noticed that cyl #1 was showing negative values below -4mg/str, and cyl #4 very high, above +4mg/str.
Anyway, noticed fuel a bit dark, suspected injector seals. Pulled the 4 injectores, and installed them in differente places. injector #1 to the cyl #2, injector #4 to cyl #3, basically moved the injectors #1 and #4 to the middle. New injector seals, new stretch bolts, 3nm+270°, injector lash set to 180°.
And I'm still getting the same result.
-4.08 1.02 1.85 1.21
-1.65 0.91 0.44 0.29
-3.55 0.74 2.18 0.61
-1.68 0.62 0.42 0.64
-4.04 1.52 2.18 0.32
-0.82 0.06 -0.06 0.82
-4.12 1.51 1.44 1.15
-3.97 1.95 -0.05 2.07
-4.12 1.56 -1.56 4.12
Cyl#1 is still cutting too much fuel, I assume that is neither injectors or seals, wiring loom is ok since i'm not getting dtcs.
Torsion value is at 1.04° and I can insert both locking pins on both cams.
Any advise where to look before start pulling of cams, lifters and head?
