Hyundai Tucson 2017​ Diesel Problems: DPF Regeneration Failure, Check Engine and Speedometer Warning Light Issues - Possible Ad Blue Tank Issue?

Hey, totally get your situation. I had a similar issue with my 2018 Hyundai Tucson not long ago. Though I wouldn't claim to be an expert (low car experience, if we're being honest), I still remember how I dealt with it. I took my ride to the local garage, got the Ad-Blue level checked, and yep, it was too low. The mechanic topped it up and slapped with me a bill of 65 Euro. Sounds a bit like your problem, doesn't it? Anyway, can you chime in with bit more info about your car's maintenance history? It might help us to guide you better. Keep calm and let’s get this sorted!

Hey, really appreciate you sharing your experience, sounds really similar to what I'm dealing with right now. As for the maintenance history, well, I've regularly serviced my Tucson, the last service being around the 95873 KM mile mark. I haven't had any major issues since. Seems like getting the Ad-Blue tank checked is a good starting point. I'm gonna take it to my local mechanic this weekend and see what he says. Cheers again for your help, fingers crossed!

Hey, no problem at all, happy to help. Your approach sounds spot on. Definitely start with getting the Ad-Blue tank checked out. It's a relatively easy thing to confirm and correct if it's indeed running low. Since you've been maintaining your Tucson regularly, it's possible the issue could be just the Ad Blue running low causing the DPF to not regenerate properly, causing the check engine and warning lights to come on. However, just to cover all bases, you might ask your mechanic to do a diagnostic check. That should signal any other potential issues needing attention. It could cost few extra bucks but might save you a load in the long term. Let us know how you get on after the mechanic visit, fingers crossed it's just the Ad Blue! Stay safe out there and keep enjoying the ride!

Spot on! You've given me some solid advice. I'll definitely have the mechanic run a diagnostic check along with topping up the Ad Blue - better safe than sorry, as they say. Once I hear back from him, I'll let you all know the latest. Hopefully, it's nothing too serious. Thanks a ton for the help, really appreciate it! Cheers and happy driving!
