Hello everyone here in the forum. My question here aims at the direction, whether there are specifications on the part of Citroën/DS what should be exchanged for a motor damage due to a fault of the cooling system! Maybe there is one or the other insider. To understand here the short story: previous owner does not notice the marten damage, the Citroën Ds4 has officially no temperature indicator. The engine overheats unnoticed. Follow: replacement engine. Now, after 17TKM, the turbo goes up. (The exact reason is still discussed). We just assume that there was a thermal pre-damage here, since the turbo in my case is lubricated oil and water cooled. First, is there any damage possible due to lack of water cooling,or is the oil cooling sufficient? Second, is there possibly a requirement on the part of Citroën/DS to exchange the loader? It is now directly attached to the cooling circuit? Does the factory have the factory-loader here. Is that a mess?
