Hello and greeting from Windhagen, I have run a problem with a Twingo Bj 1999 ,58 Ps, 100,000 Km. The Twingo jumped easily after bridging with a Würth booster, on that the Twingo ran easily in the stand about 1/2 hours. I turned out the Twingo normal to get something out of the trunk. When I wanted to start the Twingo again did not do anything. If you put the key in the lock and the starter operates the starter does not turn, immobilizer works normally }Schl Üssel out }Lamp blinks}”Plips”}Lamp goes off , key in , turn }it does itself nix}Key in the other way into the lock }it does itself nix}with the reserve key the same game.
