hi I have a golf 7 2013 I mounted door courtesy lights I made all the connections in the door cetralina in scanzione gives me the error on the doors remove it and after a while it comes back out. control unit that are led or do I have to mount resistors?

Which "puddle light" - the one on the mirror, or the one on the bottom of the door? What coding changes did you make after you physically installed the lamp?

hmm......... so, the coding change looks correct. I assume that you purchased a non-OEM after-market lanp. If it's an LED type fitting, then it will be "polarized" - meaning that the lamp will only work if the 2 x wires are connected correctly. This means that the positive wire on the LED lamp MUST be plugged into pin #16 on the 32 x pin connector and the other wire must be connected to the car's earth.
The door modules with accept both incandescent, and LED lamps - so pin # 16 on the module outputs a +12Volt supply to turn-on the puddle light. If you have connected the wires correctly and the lamp still doesn't work - remove the wire from pin #16 and connect it temporarily to a +12Volt source on the car. If the lamp still doesn't work, swap the wires and re-try the temporary +12 Volt source (you won't kill the LED by reverse-polarizing the wires). If the lamp still doesn't work, it's faulty!!

to me the lamp works perfectly the only problem that in scanning every now and then the error comes out the connection and pin 5- pin 16+

OK - what is the error message - EXACTLY?

hmm....... I assume that you installed the SAME puddle lights on both Driver and Passenger doors - if the error in your screenshots happens on both doors (which operate independently for the purpose of puddle lights), then I suspect that the problem is incompatibility.
If the error in your screenshots happens ONLY on the passenger door, then try swapping the puddle lights - does the fault message follow the puddle light that was installed on the passenger door?
If so, the problem is in the old passenger door puddle light. If not, recheck your long-code settings on the passenger door

the problem is on both doors I can try to detach both of them for a while and see if it will give me the error in scanning again. if i found resistances do you think i could solve?

nicola : hmm....I'm guessing of course because these lights are not OEM equipment - but doesn't sheer logic suggest that if the same problem happens on both doors (which are independent modules), then there is a fundamental question of compatibility with the new equipment?
As I've said, the coding looks correct and the connection points are really simple - so very low risk of installation error. I'm really not sure what resistors you mean. There are "shunt" resistors that are sometimes used on LED lamps that replace incandescent lights. These resistors add electrical current draw to the LEDs to fool the module into thinking that an incandescent lamp is still fitted.
It's not clear what type of "electrical error" is causing this problem - meaning too high an electrical current. or too low electrical current, or another aspect of electrical operation. If you do try a resistor, make sure that the value is compatible with the normal small wattage of the OEM incandescent puddle light (check the VW P/N)

the lights if they are detached from this errorr  |

yes, Chinese after-market equipment is not the best quality.
Not sure what you mean by this: "the lights if they are detached from this errorr"

yes it gives me this error if I disconnect them from the plug

nicola : Is that so surprising?
If you physically disconnect the puddle lights from the plug and if the you leave the coding unchanged - haven't the 2 x door modules been asked to operate puddle lights that are not connected? Hence the error message!!
