VW Passat B5 1.9 tdi 101 km - Description of the parameters of unit injectors in

Hello, I recently bought a Passat 1.9 tdi 101 km AVB from the beginning, when the engine was cold, it started to smoke white after a few minutes as it got hotter.Everything was ok. I connected the car to the vag and showed me error 16686 (Cylinder 2 - misfire) in group 13 - the cylinder 1,3 and 4 were in the range, while the 2 had a result of 2.99 and it did not even tremble after replacing the unit injector at the first firing, it still smoked, I deleted the vag, I drove a few kilometers so that the engine warmed up and in group 13 it was still on cylinder 2 there is the same value I will add that group 18 is ok and 23 all values are below 30. Please help me because I have already invested some money and I do not know what to do next
best regards

Injector corrections are an indicator of cylinder power and not the quality of the injectors. Check compression, combat condition and hydraulics.

Ok and what should be the correct compression

Compression 25-31 bar

And you have not replaced the turbine recently ??

yes in the same, and could it have any meaning? The car is still smoking with white smoke as it is cold after warming up like a weed in the vagu, still in block 13 on the second cylinder, the value of 2.99 although it drops to 2.1 more than once, I don't know.

Well positioned injector pins in the plug checked.

The pins of the mechanic were checking with me, he was cleaning something there, so okay, it may be a proof, for example, that in group 18 and 23 the parameters are ok, i.e. in 23 the first two cylinders are in the minus of approx - 5 to 9 in the 3rd and 4th cylinder about 20 to 40 as to the correct setting, I think it's good, unless you have some advice, I could give the mechanic something, it's my friend, so I don't think he will be offended

It can make a difference because the cranks can be crooked. Check the cranks.

Cranks or what is the crankshaft? Somewhere I have already read something about cranks, but I don't really know what's going on

Let the mechanic change the injections, for example, 2 from 4 and check the parameters.

So how to transfer the injection from cylinder 4 to cylinder 2 where there is a parameter of 2.99 and it will continue to be unchanged, can it be a woman's curve?

If it is still the same, check the connection between the injector and
engine controller, shaft what colleagues wrote above.

Hello, I have an appointment for compression on Saturday, so it will turn out, but it only started to worry me, the oil level on the dipstick is rising, the coolant is not decreasing, the color pink is what can it be?

Seals (O-rings) on pump injectors to be replaced,

All mentioned

It can also get through a tandem pump.

Could this be the reason for white smoke when starting when the engine is cold?
