Hello, 1.6hdi, as you know, has a disadvantage with releasing washers and gaskets under the injectors. In my case it is injector # 1, it is wet all around. I would probably ignore it, but I think the engine is a little too loud and vibrating too much. after connecting lexia, correction of injection No. 1 is +2.81, and injection No. 2 is -2.80. The question is whether the injectors are to be regenerated or because there is a leak in the injection gasket No. 1. I would not like to replace the gaskets and then give the injectors for regeneration and replace the gaskets again.
