Hey, I had a pretty similar issue with my Volvo S60 Diesel (2019 model) a while back - a blinking check engine light along with a stored fault, it drove me nuts! Just an FYI, I'm not an auto-genius, just a guy who's got some experience under the hood. I took it to my local workshop and after a bit of head-scratching they found it was due to a Defective fuel filler flap wiring harness! Saved me a lot of guessing around and potential missteps trying to figure it out on my own. It cost me about 155 Euro though, which was a bit of a stinger but better safe than sorry, right? On your S90, I'd recommend taking it to a professional, if that's possible. It would save you a lot of headache and potentially further damage. It could be that you're dealing with the same issue, but, anyway, could you share more info about your car to help me nail this down? Hoping we can get this sorted out for you.

Hey, appreciate your advice and sharing your experience. My S90 has clocked in about 122272 KM, if that's of any help. I had my latest service done just before it hit the 120K mark. Given your experience, it seems wise to take it to professionals for a thorough check. I wouldn't want to brood over this more than I should, haha! Fingers crossed that it's nothing more severe than the wiring harness. Thanks again for pointing me in the right direction, cheers!

No worries, always happy to help! The mileage you've clocked is quite a bit for a relatively new model, but then again, all cars have their quirks, don't they? Also, given you've had a recent service, I would've hoped they'd catch something like this, but sometimes these things slip. Going to a professional, especially with the specifics for your model, is definitely a wise move. They've got the right tools and knowledge to correctly diagnose your problem. As you've also correctly pointed out, we can only hope it's something as straight forward as the wiring harness. Feel free to keep this thread updated. I'm interested to know what the issue turns out to be and how it's resolved. Again, hope it's an easy fix for you. Drive safe!

Sure thing! I'll make sure to update you once I have a clear diagnosis. It's always good to share this kind of knowledge, you never know who it might help out. And yeah, hoping it's something as simple as the wiring harness and doesn't create a bigger hole in my pocket, haha! I like keeping my rides in top shape and any unforeseen issues kinda irk me. Thanks for your recommendations and concern. Time to take old Bessie to the docs! Drive safe and catch you later!
