Accelerating Gas to Petrol Switch: Audi A4, Reducer Pressure, ECU Errors, VAG, Autoadaptation

I'm not smart in this area but I have a problem with the gas installation.
The temperature outside is what it is but when I accelerate quite rapidly from gas it switches to petrol (exactly the control unit beeps as there is no gas).
At the beginning, when I set up a new installation, when it switched, the mechanic tightened the screw on the reducer, increasing its pressure. For a year it was fine and now the cylinder is 3/4 gas, and here it switches to petrol when I accelerate.
1. Is it caused by erasing ECU errors with VAG? Because recently I deleted inspections in the car and errors by the way.
2. Can I tighten the screw in the reducer? So how much turnover?
3. Should I buy an interface for the gas installation, take a picture and put it here (I have the program)?
4. Is it good to carry out Autoadaptation from time to time?

Except this everything is fine. I suspect that if the temperature of the fluid was 70 ~ ~ 90 degrees, there would be no problem.

Data :

Audi A4 engine 2.8 V6 AAH 174 PS year 1995
Sequential installation
ESGI computer 2
VALTEC 3 OHM injectors
reducer ZAVOLI Zeta/S
ESGI switchboard

Is it possible that I filled up with the wrong gas?

everything is fine, only the gas is very cold (it's cold in winter) and in these natural circumstances the reducer is not able to evaporate the required amount of lpg, the pressure drops and switches to petrol. Foot off the gas and just until spring. Do not turn the reducer. Do not perform self-adaptation without a real need. However, if you cannot wait until spring, either install a second reducer or replace it with a larger one.

It is also always worth replacing the liquid and vapor phase filters.

Thank you for your reply. I will not interfere because I do not know.

Witek, if it's any consolation, I have the same in my Nissan
I asked the mechanic and he didn't tell me to do anything but wait for global warming

but I recommended replacing it with a real reducer, which has the declared power in the conditions of the Russian high, and not only in the sunny climate of Palermo . A strong reducer also means less crap in the reducer or injectors. It's always better to be too big than even a little too small. Oh, and a hoof not frogging

hello, zawola evaporators have a factory defect, you need to unscrew them and remove the copper springs on which the muck settles

But this reducer is about 2 years old. So exchange? I called the specialist who put it on me and he said - "fill up gas somewhere else"

And has your friend changed the gas filters at all during these 2 years?

He didn't say anything because nothing happened

So you didn't replace the air, oil and A/C filters either because nothing happened? :D

every 15,000 I am replacing this filter so I think you should do that

I had the same thing. I insulated the reducer with mineral wool and wrapped it with foil. And I put foam pipe lagging on the fluid lines.
1. In the morning it reaches temperature faster and switches to LPG
2. Even when parked for about 1 hour, it starts immediately on LPG and maintains the temperature
3. When accelerating, it does not switch to petrol

Well, you have the answer, clogged filters cause a temporary pressure drop, which the controller considers as a lack of gas and switches to petrol. Replace filters will rather help.

the liquid phase and volatile phase filter should be replaced every 15 kkm, not when it is impossible to drive. Replace immediately and you will see for yourself how much dirt is in them. The volatile phase filter absorbs heavy fractions of hydrocarbons that like to contaminate injectors, after some time it loses its absorptivity and does not clean anything, or even the opposite. I recommend the volatile phase filter FL02 prod. Czaja

tino2003, don't make fun of me . I replace everything on time. Well, with this gas I neglected it a bit.
Today I went on a little tour. temp. I had 70 degrees of liquid. Everything was running as it should.

I had exactly the same thing, changed the filters and everything stopped

Hello, I also have an a6 c4 with lpg, I drove the greatest frosts without major problems and now similar symptoms . As for the filters, you are not alone Witux has not been replaced for almost 2 years. Regards

I haven't done anything at the moment and the car runs like lightning Apparently, maybe some crap or really does not like low temperatures.
