Two things :
1) I still have a turbo-diesel: there is a decanter before the diesel filter, precisely to avoid the water (whether it is condensation in the tanks or in the tank). They don't put it on modern cars anymore ??? Where do people not serve?
2) Of course there is condensation in the tanks. Put a bottle of cold water on your table on a stormy day and see how it flows! So ditto in your tank: you drive, comes in "stormy" and therefore "humid" air which fills the tank, the car sleeps outside and the tank cools (more or less, depending on the weather), therefore condensation (more or less) ... It's not winter, when the air is dry, but these days, when the air is humid ("heavy weather" as they say). In inter-tropical areas ("heavy" weather during the day, significant cooling at night), on construction sites, the instruction is to fill the tanks in the evening when returning to the park, and not in the morning at start-up, precisely to limit the condensations ...
3) People should realize that modern "direct injection" diesels are gems of technology. Either it works, and so much the better. Either there is a breakdown, and it is a disaster - almost irreparable. Fortunately, we all know of hundreds of cases where this works. And possibly a case where there is a glitch.
I laugh because on others forums, I iron on pellet boilers. Many people give up because they are told that it is complicated, that there is a lambda sensor ... And they continue to drive quietly in direct injection diesel without asking any questions! The same !!!! Go understand the "average consumer"?
