Moin, the net is full of this problem. Now it has hit us too. The good Twingo has fresh Tüv, but doesn’t start and central locking doesn’t work either. We only had the key re-read and have it re-learned at Renault in the fall. The impulse encoder / reverber is also new. The Renault plants here in Hannover are not able to change anything at the present state. The master thinks the decoder box is broken and I should like to have a new + key + Fhgn But will that be the solution to the problem? I’m not sure. It’s the only Renault factory here and it doesn’t have a good reputation. On eBay is offered by the company “Autoschlüsselexperte” to build a new key or transmitter. This is supposed to cost 90€ in advance…… Used ECUs are also available with decoder box and key. But for 150€ without guarantee…. Well… I also read the possibility to cut two three cables at msg… Which would that be? because and what has to be done additionally? There has to be a way to get this good car to run… He has Tüv until May 2019 and only needed a new esd…. Is there maybe a company where you can send in the msg? Thanks already and sry if the Wfs threads are annoying lG
