VW Golf 5 2.0tdi BKD Engine Vibration / Shudder only while accelerating
Hey Guys
I've got a Golf 5 2.0tdi manual BKD engine, When I accelerate the car vibrates and if I keep it in the gear and continue to accelerate it will then shudder, I feel it through the seats and not through the steering wheel. It only does it when I accelerate, I have replaced the clutch and dual mass flywheel as well as the both inner CV,s which hasn't resolved the problem. After this I am convinced the vibration is coming from the engine because when I change gears the frequency of the vibration also changes with the engines.
I've scanned the engine and comes back with no faults.
The issue started when I changed faulty injectors, at 1st I got a fault on injector 4, swapped it out with a used one and the car ran perfect for 2 weeks then got the same fault on injector 3 & 4, then swapped those 2 injectors out with used one as well. Since then It been vibrating through all gears.
What gets me is that there is no faults, I've checked the injector values and on idle they all seem fine, I've logged the car while driving and those values go up a lot.
Here are the values logged with VCDS under "Injection Quantity - Deviation" while driving the vehicle.
REVS Cyl.1 Cyl.2 Cyl.3 Cyl.4
1344 -0.42 0.49 -0.12 0.02
1512 -0.45 0.49 -0.09 0.05
1722 -0.47 0.49 -0.07 0.05
1953 -0.47 0.49 -0.07 0.05
1803 -0.47 0.49 -0.07 0.05
1239 -0.47 0.49 -0.07 0.05
2331 2.45 -3.01 2.99 -2.47
2079 2.45 -3.01 2.99 -2.47
2100 2.45 -3.01 2.99 -2.47
2121 2.45 -3.01 2.99 -2.47
2163 2.45 -3.01 2.99 -2.47
2205 2.45 -3.01 2.99 -2.47
2247 2.45 -3.01 2.99 -2.47
Can anyone here please assist, as I now have to consider sending in all the injectors to get them reconditioned but that will be a costly exercise and it still might not resolve the issue as it might be something else completely?
