Moin moin, with 133k km my V50 is probably just in a “difficult” time. After defective wheel bearing the following can be observed now 2k km later: If I drive with the vehicle “longer” (20km up) routes, then a diesel / smoke odour in the interior is very easy to perceive when standing at the traffic light (not during the ride!). I have already googled and is mentioned again and again the seal to the vents under the bonnet. I would exclude this first, since it a) looks good and b) the smell can still be perceived outside the vehicle (if you stand 1m away from the engine). So if the air around the engine stinks anyway, then the best seal can’t save anything anymore. Now only the question is what I can look at? Otherwise it continues to be great: no power loss, quiet engine run, no warning lights etc. Even with short distances no smell is noticeable. Thank you already for your help. Fos forget, so I like to give them after. Ahja: I am absolute layman and therefore ask for forgiveness when I ask “doof” questions.
