VW Nivus Starting Problems: Ignition Switch Mystery

Having some experience with car repairs, I faced a very similar starting issue with my 2019 VW T-Cross. The symptoms were almost identical, problems with the engine start and unexpected shutoffs. Initially thought it was the ignition switch too, but turned out to be much simpler. After checking the starter motor and other components, the workshop found a blown fuse that was causing the dashboard lights to flicker and creating starting problems. The repair was straightforward, just needed a fuse replacement and system check, costing 52€ including labor. Before jumping to conclusions about the ignition switch, could you share: Are any dashboard lights showing up when this happens? Does the key turn smoothly in the ignition? Have you noticed any electrical issues like dim lights or slow power windows? When was the last time you had a battery check? These details would help determine if your issue matches what I experienced or if it might be something different in the starting system.

Thanks for sharing those details. During my most recent service at 129004km, the mechanic actually pointed out potential ignition coil issues, which matches these symptoms. The car electronics diagnostic showed irregular voltage patterns, suggesting it might not be a simple fuse problem in my case. Had the ignition coils tested and two were indeed failing. They were creating inconsistent sparks, leading to those rough starting issues and sudden shutoffs. The car ignition system needs all coils working properly for smooth operation. My starting issue actually got worse in cold weather, which is a typical sign of failing ignition coils rather than a blown fuse. Worth checking the coils before replacing more expensive components. Has your starting problem also been affected by temperature? This could help confirm if we are dealing with the same issue.

Thanks for the follow-up about the ignition coils. Looking back at my VW T-Cross issues, I actually experienced something very similar after the initial fuse replacement. Within a few weeks, the starting issues returned, especially during cold mornings. The key would turn normally in the ignition switch, but the engine would struggle to maintain consistent running. After further diagnosis, my mechanic found two faulty ignition coils, exactly like your case. The irregular voltage patterns from failing coils caused both hard starting and rough running. Final repair included: Replacement of 2 ignition coils: 180€, New spark plugs as preventive measure: 60€, Labor: 90€ Since fixing the coils, the engine start has been perfect regardless of temperature. Your diagnosis makes complete sense, the cold weather sensitivity is a classic sign of ignition coil failure rather than an ignition switch problem. Have you already received a quote for the ignition coil replacement? The parts cost can vary quite a bit between suppliers.

Thanks for the detailed information about your experience. Yes, I already got quotes from several places for the ignition coil replacement. The prices range from 290€ to 380€ total, including parts and labor. Most places recommend replacing all spark plugs while doing the ignition coils, which makes sense given the mileage. The symptoms match perfectly with what you described, especially the cold weather correlation. The car ignition is definitely more problematic on cold mornings, just like your case. My dashboard lights remain normal during these episodes, which further points to the ignition coils rather than electrical issues. Going ahead with the repair next week at a shop that specializes in VW ignition systems. They quoted 320€ total for new coils, plugs, and labor. Hopefully this resolves the starting problems completely like it did for your T-Cross. Really appreciate you sharing your repair costs, helps confirm the quote I received is reasonable. Will update once the work is done.
