Seeking Advice on Troubleshooting ABS/DSC Warning Light Issue in 2012 Volvo C30 Diesel

Hey everyone, I’m having a weird issue with my 2012 Volvo C30 Diesel. The ABS warning light popped on, the ABS/DSC system is acting up, seeing a warning light in the speedometer, and a fault is being stored. I'm suspecting the issue might be connected to the ASC system, but I'd love to hear if anyone else has had similar experiences. Specifically, I'm interested in how you got it fixed and any experiences you had with a workshop. Any tips or advice would be hugely appreciated!

Hey there! It's funny because I had something similar on my 2010 Volvo S40. I'm no car expert, just your regular car owner. After a few frustrating moments, I took mine to a local garage, they diagnosed it and turns out my ASC relay was defective. It wasn't a huge job, cost me around 90 Euro. However, without more information on your car, it's hard to confirm if we experienced the exact same issue. But it's definitely worth checking out the ASC relay as a potential culprit. Best of luck!

Hey, thanks for the quick reply! Interesting that you experienced something similar. Good to know it wasn't a major repair. Your suggestion about ASC relay sounds sensible and I am going to consider it. My C30 just hit a mileage of 139,366 KM, had its latest service a little while ago, and has been running efficiently except for this problem. Shall update once I get it checked. Cheers.

No worries, bud! Seems like your C30 has been reliable - Volvo for the win! I still stand by the possibility of the defective ASC relay given its role in sending power to the ABS pump. With your mileage, it'd not be unprecedented to experience component failures like this. Also, just a heads up, sometimes the ABS/DSC fault can be linked to a failing ABS pump or sensor issue too. Anyhow, try not to stress too much, the chances are it's fixable and won't break your bank. So, fingers crossed, and let us all know how it goes. Safe driving!

Thanks again! Volvo surely is a beast. I can't deny the possibility of it being the ASC relay after considering your points. A faulty ABS pump or sensor could also be offenders like you suggested. I appreciate your input and the assurance. I feel relieved that it could turn out as a minor issue. I have decided to take her to the mechanic first thing tomorrow. I'll keep everyone updated once the problem is identified and resolved. Drive safe, everyone!
