Hello together, and again a problem. Wanted to start my car this morning but unfortunately without success. The engine turned well through but it did not jump on. The pre-glow control light lit about 10 seconds before it went out. After several trying also the battery made so that I tried it with start aid over the car of my wife further. After about 6 seconds start appeared on the display “Pre-glow system not available” Is there the Voglow system defect or can it be d or is the battery too weak, do you have a recommendation for a reliable battery? I would like to thank you in advance for your support. LG Micha
