Any idea if there is much parasitic load on the MK7? I would expect a minute amount from the alarm and the KAM. My MK7 will likely sit during the week and only be driven on weekends. The parasitic loads on my Powerstroke are substantial and I ended up installing a Battery Tender under the hood as it sits in the garage till needed for towing. Wondering if I need to do the same with the MK7.
