Opel Signum 2003: Power loss and ABS/DSC system faults

ABS/DSC system is not working

Hi guys, I need your help. My 2003 Opel Signum with a petrol engine and 179067km mileage is currently causing me some concern. The engine is losing power, the ABS warning light is on, traction is lost and the ABS/DSC system is not doing what it should. Could this be a problem with the supply voltage to the speed controller (ABS)? Have any of you ever had similar symptoms on your car? How did it go with your mechanic? I had no luck last time and would like to be prepared. Thank you in advance. Greetings, [your name]

Hello, I encountered exactly the same problem with my 2006 Opel Vectra. Like you, the ABS warning light came on in my car and I had a loss of power when driving. After much pondering, I discovered that the control unit was faulty. That was a really tough nut to crack. It turned out that this problem was quite serious, as the control unit is responsible for the entire electronics of the vehicle. It was not an easy job and it took some time to get it fixed and get my car back on the road. I would therefore strongly recommend taking the vehicle to a trusted mechanic and having the ECU checked. It could be anything from a simple software problem to the need to replace the entire ECU - unfortunately neither is particularly easy. Greetings, [your name]

Hi, thanks for your quick advice! It looks like I'm unfortunately having bad luck with my car again. If it really is the control unit, that sounds like quite a feat. Do you have any idea how much it cost you? And have you had similar problems again since then or is everything in the green zone now? Best regards, [your AI name]

Hey, after a visit to the mechanic, everything is finally in the green zone! The fault with the supply voltage to the speed controller (ABS) has been rectified. As for the costs, I had to fork out around €1000 because my control unit was faulty. It was quite a lot of money, but since then my car has been running like clockwork again. I haven't had any similar problems since and I hope it stays that way. Greetings, [your AI name]

Ok, that may sound like a lot, but what can you do if you are dependent on the car. The most important thing is that everything runs smoothly again afterwards and no further problems occur. In any case, thank you for your report and your advice! I will now take my car to the mechanic and hope that it won't be too expensive. Regards, [your name]
