Hello, 2011 passat 1.8L TSI. Very frustrated...Car starts, runs well for two seconds then dies. This repeatedly happens. Backstory.....It had been sitting for maybe 6 weeks. It's been using a lot of oil so wanted to do a compression test.To do that I removed ignition and fuel pump fuses. Went to start it and found battery was flat. Changed to another battery but it also didn't last long. Charged it up overnight. Returned fuses so I could warm up car prior to compression test. When car did run was running a bit rough. Scanner said cylinder 2 coil needed to be replaced. Did that. Started again but runs smoothly for maybe 2 seconds then dies. This now happens repeatedly with no change. Checked fuel pump and it seems to work fine. Scanner reported mainly low voltage issues due to the dead batteries. I've read various possibilities including immobilizer issues (tried two different key fobs and no change, tried a couple of suggested reset methods and no change) and steering control module (haven't done anything with that yet). Does anyone have any knowledge on this? I believe that it's likely to be an electrical issue rather than fuel issue alone. Immobiliser maybe? Key locks and unlocks. Everything else appears normal. Just wont kep running beyond 2 seconds. Any help appreciated. Thanks very much in advance.
