Jetta tsi 2013 2.0t no power epc on

Well to begin. I appreciate all your help into this matter.

I bought this jetta in December and since then cannot enjoy the car.

First problem is a code p0441. Looks like it’s normal for vw engines. Ok I learned to clean the charcoal box (canister) and never put more then 50liters of gas. Ok. But even doing that the code still on.

Ok.

Second problem is: car stalls.
If I go to do some errands then when I stop for a períod between 10-30 minutes and come back to drive again. The car won’t run. It turns but no crank. Unless I wait 30 minutes then when I crank, it runs right away. I realize that when this problem occurs there is not lights and no codes. Also no signal to fuel pump neither to the ign coils.

Third problem is the worst. Under heavy acceleration, full throttle, car gives up. Epc comes on, either on 2nd gear if I am on s mode or 3 gear on d mode. Epc light on, car looses power. Won’t rev (full throttle above 4K rpms). Codes presente are 164b oil pressure sensor.
If I go gently on the throttle I can reach full speed with the light present. Car went to 2 different mechanics. Nobody no what’s going on. Car right now it’s in the shop for the last 2 weeks. I don’t know what else to do.

I replaced the charcoal box and the oil pressure sensor. I swap with my friend fuel pump with module (low) and 2 hpfp. The problems still presente even after the change.

I change the oil too. That’s all I’ve done so far.

In the past I had some codes but never wrote down before erase. I remember p025c came on.

I am located in brazil.

Need you help please.

1st problem:

No, it's not normal for VW or a any other manufacturers' engines to give a p0441. The code indicates incorrect purge flow and should be diagnosed as such, from the purge valve to the tank filler cap.

2nd problem :

This may be heat related. Do you have a rpm signal when the car cranks but not starts. Did you check crank and cam sensors for proper signals? Without these nor the fuel pump will work nor the coils will be triggered..

3rd problem:

Check the actual oil pressure, if it's okay then c heck the wiring. Same thing for the P025C, this might be wiring issue. You will need an appropriate wiring diagram.

ok, cool...i will pass on to the mechanic. i will get the car from the mechanic that had for 20 days without success and i will go to another shop 3k miles away, and i will give to him this instructions.

i appreciate you... i will update as soon as i have news.

Updates on my problems.

Mechanics in my town are not capable of discovering anything so far. Tomorrow I will go to a dealership before decision to send the car to a shop 3k miles away.

One mechanic told me could be the pressure sensor in the block the is related to the problem for the Epc light on and lost of power.

Question. What’s is this sensor pressure in the block ? Picture ? Link to a description? Part number ? Etc. ??

I spoke to the ex owner and he said he sold to the dealership like that. He knew it was broken. he also said that epc on and loss of power only happens during oil temperature above 100 degrees.

And guess what?. Today I tested on the highway and realize that the car with oil below 100 regress does not turn on epc light and does not losses power.

But

After that heavy acceleration keep stalling after you turn it off.

I have to wait one hour for the oil to go down in temp to crank and run to take off.

Anything guys ?

Please help. I am going nuts.

Thanks.
