I just got similar conclusion. It seem that this particular engine is very sensitive for proper timing and doesn't forgive any misalignment. Sure I have VCDS and CarScanner pro so I can check. But I'm not sure if this engine has any oil pressure sensor. All I can see on the sensors list is just oil pressure switch which will not give nothing here as its role is just to say "I'm running on dry". The other hand on the measuring blocks Indeed I saw a values of timing valve. I jumped into the details of sensors and actuators of this engine and yeah at the end of camshafts there's two sensors, hall efect for shaft possition. I'll check values for cams alignment I think I saw set and read value. I'll try to correlate this with shudders. Mine engine behaves very similar to this one from the link below, mine 4cyl instead of 3 and mine slightly smoother and not all the time. But the timing belt is original on mine, never replaced. If this is an Issue then wroung setup on the factory or variable pulleys or valves have enough or faulty. Anyway sensors for real cams possitions should have catch this. So for now: 1) Check on the blocks what's the corelation between sensor shudderring vs cams possitions. 2) Buy camshaft blockades and redo timing. They're reasonably cheap. The

Hi, couners for misfires doesnt reflect this issue. They almost doesnt count any. Or engine can't recognize misfire if appears idneed. Anyway direct misfire is more sensitive in appearence when you're in car. This is rather rough idle engine wiggling. But I think this is not an issue of missfire. Plugs and coils replaced w/o effect. When lumpy making pedal to the metal for a moment makes some stabilization for a moment and again lumpy. But this is risky on the trafic lights because car next to you thinks that you want to make a race 🙂 I found this is not for all 1.4 tsi but a lot, a LOT of them has this issue reported from the very first miles. I suspect this can be caused by cam shaft timing? This engine has two VVTs and If I see correctly, no sensors to controll its possition, but this is just my suspicion. Also I can see that this engine is very lazy to controll ignition angle when idle. I do know that the other brands controlling this when idle. This engine go for arround 0 (I assume as a correction from base value as ignition on top dead point makes no sens) when idling. Anyway almost everyone is replacing spark plugs, ignition coils, cleaning carbon buildup from the intake, as I did, and nobody have solved this issue by those efforts, me either. Going back to the dealer makes no sense, where authorized service looks like a kindergarten, and the's a problem with changing tire, what to say about the diagnosis whene engine doesnt spit any code. I don't want to offend anyone, but this is my impression of several visits there. And no, VCDS doesnt allow for idle adjustment for 1.4TSI, It's possible for TDI for some range but not TSI

For sure but it should not act that way. ECU has a lot of sensors and actuators to hold engine as silk. Slightly increase idle by pressing pedal also works but i cannot assume it as solution. When acc pedal is pressed even for 800rpm there's no idle anymore. Antway can anybody tell if 1.4 tsi allow to increase idle as a parameter like 1.6 tdi does?

Hello Guys, I have exacly same issue. Engine is shaking on idle when wormed up. Exacly as described in the topic. The wormer then more. Spark plugs is not an issue here. Been replaced. Intake was cleared, there was some carbon but not much. Not an issue, still same. Firmware on rhe ECM is up to date. Ignition coils not an issue. I found that this problem was reported by previous user on firt service, so this problem starts from the beginning. No errors stored on ECM. Maybe SB have some findings on this annoying issue.
