Hello together, I am facing a problem with my space tourer and would need your help. On Sunday an error message in the exhaust system came in, and the Adblue light lit up, but disappeared after a short time. On Monday the problem reappeared, and shortly afterwards there were also errors in the engine control. Due to my previous bad experiences with the Citroen workshops in our area, I turned to an independent workshop. The result: pressure too low. It seems likely that the AdBlue tank has to be replaced (I would also like to do this after researching this in the forum and considering this to be useful). We have refilled the test and reset the warnings, but the light again lit up after about 17 kilometers. The workshop thinks that replacing the tank is basically not a problem. However, it was noted that I ask Citroen for information. should be, if there is a software update, because they already had a similar problem. They can not do the update themselves. They also said that they might not be able to change the tank, because it may have to be programmed. It is uncertain whether their programming device can do that (although it is supposed to) – but I am relieved about the honest assessment of the workshop. I have also asked Peugeot, who do not do it – even if similar Fa hrzeug. My questions: Has anyone heard about this update? My previous Citroen workshops have always kept everything under lock, as I had a maintenance contract until August. So I have no documentation about whether an update was carried out. Does the tank really have to be programmed? Can it really not be simply exchanged? Has anyone here had similar experiences? Thank you, Ralph
