Good day, I would like to mount a trailer coupling on my V70. Now I have been researching here for some time, at rameder.de, at aukup.de, at Volvo, etc., but look less and less, especially because the information contradicts. Perhaps someone can clarify.Vehicle V70, 2,4D, 120kW, BJ 01/2006 no level control HSN 9101 TSN AAJArt of the coupling Removable to the rear results in a black brick at the rear. Or am I missing something? Detachable down seems optically best, but reduces the rear embankment angle, which is already critical for the loaded V70. Can anyone quantify the embankment angles for the different couplings?Electric set At this point it becomes really difficult for me. Rameder recommends vehicle-specific electric set with Summer as a turn signal failure control without software release from Volvo. Alternatively, a set for CAN bus is offered. the software release is required. Here in the forum it is reported that it could be done via the dashboard lights even without software release. Others say that everything is then possible except shut off the fog-finish lights and the return sensors. I don’t care about both. What’s right now? Is this perhaps dependent on the model year? Leting original parts installed directly at Volvo is honestly too expensive. You can rent a transporter every time cheaper. Greetings to Nippes
