Opel Meriva 1.7 CTDI diesel - goes out while driving, wave turns

I warmly welcome !
I have a nice agile Opel Meriva ctdi (diesel) 203 car released in Spain
For some time, the car likes to go out while driving - sometimes it will start immediately and sometimes you have to shoot a few / several minutes.
Most often it lights up simultaneously:
1) the track stabilization system has a malfunction
2) fault in the exhaust emission control system
recently replaced
1) scv valve
2) fuel filter

Sometimes you can drive 1000 -1500 km without problems and it is just like yesterday when on the 300 km route I died about 20 times - most often it happens when the speed is changed, low speed and on a very uneven surface (tram lines, pits and dirt roads )
for a more complete picture I attach a video as I shoot ...

you have in mind - crankshaft position sensors?

Hello. In this model, the engineers placed the power steering gear near the steering gear - that is, under the car - the computer is exposed to incredible moisture.

The indicator lights up so you need to connect the tester and read the faults in the engine. It can't be done otherwise.

so can it be a sensor?

I did it four times - no engine defects - the only thing that seemed before was a fuel system leak

Well then. You have a problem with fuel pressure. You have to look here.

I warmly welcome ! Yesterday on the road - about 130 km went out about 20 times .... I will mark that I go beyond the eastern border and I often refuel there
I went to the diagnostics of the buyer and there says that it is a clogged valve .... (a month ago I replaced the dv denso valve! and 2 weeks ago the fuel filter. On the border I got tired a little and in Poland already 150 km without problems ... maybe damn quality fuel? maybe you need to clean the tank?

You've got the answer - the smell of saler is in itself petroleum - I know a person who has been driving vw b4 tdi to Bezledy for 15 years but he has been refueling his car on the Polish CPN.

I can't stop going to PL to orlen to refuel I have to watch over the company
will the fuel cleaning fluid help?

I think that the PLN 25 invested will not worsen your budget significantly - the brave world belongs.

I sold a grandpa !!!

I will write something for others since the car was sold. Someone may hit my solution. I had the same problem (the same engine) and when I started firing, the battery reached almost zero. Accidentally on a lit engine I leaned on the plug to the controller and the car went out. I disconnected the battery, unplugged both plugs, sprayed the contact and blown the compressor, probably about 3 times. What was my surprise when he lit a dead battery with an arrow. I drive for a long time and the problem disappeared and appeared every day. I breathed a sigh of relief because I was about to take the Denso valve. Regards.
