Radio hole or refusal to work?

Hello everybody! That the Phaeton is quite idiosyncratic is not a secret. In the case of a “new” (likes me for weeks) incident I wonder if there is more behind me. On my car three of the four pushers do not work to close the door handles, the fourth is also winter-tired, so works only from double-digit plus degrees… so far, so bad. What surprises me: not always, but when the button works directly on the parking space before work Sometimes (also only there!) completely Kessi falls out, I sometimes only get into the car with the key in the lock and have to use there (oh grey!) the key to start. Even the radio remote control doesn’t work anymore. Only the trunk can then be opened (at least once randomly) still by pressure on the VW symbol. If only the radio was disturbed, I would start from unfavorable interferences. But complete failure (sometimes only the button, ma Not once no access detection outside, sometimes only delayed key detection at start-up attempt…) of the “wired” components…? In summer I definitely only have the problem before work, in winter he spins anyway. Is my work allergy contagious…?! lg Stefan
