Hello and HELFEEEEEE! I got changed a nearly dead battery yesterday at my Laguna Grandtour 2 (Diesel) and first of all everything ran like smear again. He jumped up this morning… drove quite normally but when I turned it off (ignition off) the on-board computer did not go out anymore or jumped immediately again and checked in ahead. Then he also shows strange things like immobilizer, ABS, airbag, light automatic etc. please check on. In the meantime it’s been a few hours and now e He doesn’t know the keycard anymore, please check the immobilizer on the display and if I press the start button nothing happens. Is it enough for the laptop and read out errors? And the most important question: how can I get it back to the workshop at all? A colleague of mine has just disconnected the battery…
