Hello guys, I own a Volvo V70 III 2012 2.0 163 hp diesel engine. Currently with 311,000 km. I have various electrical problems: – Electric trunk does not open – Sometimes I stop the locking mechanism, but nothing from the electric motor – Sometimes I hear that the electric motor does something, but the lock remains closed. So the trunk cannot be opened. – When I drive and have my lights on, several sensors give a warning when braking. – The sensor for the trunk indicates that it is open, but it is not. On the display this warning sometimes goes very fast on and off. – Sometimes it tells me that the key is not close. I have no Keyless Go, only the key in the slot. – It indicates a warning that Start Stop must be maintained. – If I drive without light, these warnings do not appear, but the trunk cannot be opened either. – While the engine is running, I hear a warning. When I turn off the light, the noise is no longer there. The problem with the trunk occurred first. Because my start-stop system also did not work properly. When I switched on the engine and ran the engine at about 3000 revolutions per minute in the parking position, the trunk opened when I pressed the button. But at that time I also had the problem with the trunk sensor, that it was the trunk as a but after the battery change no longer, until now. I checked all fuses, but nothing was out. The battery gives me 12.6 V when the engine is off when it is on, its about 14.4 V. I also checked the cigarette lighter front and rear, which also showed more than 14V. It must either be a ECU or a cable is damaged. If it is the ECU, which could it be? Does anyone have an idea how I could proceed to ide the problem. And how can I open the trunk if the electric trunk can’t be opened? I’ve searched many pages, and it says everywhere that I either have to unscrew the handle from the inside or from the outside under the handle, but I couldn’t find anything that can be opened. Thanks for the help!!
