BMW X5 Cold Start Issue, Owner Seeks Advice

Hey there! I had a similar issue with my 2003 BMW X3 3.0i last winter. The starting problems you're describing sound exactly like what I experienced. In my case, it turned out the battery cables had significant corrosion at the terminals, and the connections were loose. When I took it to the garage, they found the positive terminal was barely making contact due to buildup and wear. The mechanic cleaned both terminals, replaced the corroded cable ends, and secured everything properly. It wasn't a major repair, but it definitely needed to be addressed before it could cause more serious electrical issues. The starting problems disappeared completely after fixing those connections. Since you mentioned the engine control light, I'd suggest having the battery and charging system tested too. These symptoms often show up together when there's a power delivery problem. Based on my experience, this is likely a straightforward fix that any competent mechanic can handle, doesn't need a BMW specialist for this type of issue.

Hey, thanks for sharing your experience! That actually sounds really similar to what happened to my X5. I ended up getting my battery cables fixed too, super helpful advice. Do you remember roughly how much you paid for the repair? Also curious if you've had any other electrical gremlins pop up since getting it sorted? Mine's been running fine so far but always good to know what to watch out for with these older BMWs.

Hey again! Absolutely happy to share, glad my advice helped you out! The repair cost me 155 Euro for fixing those battery cable connections, and it was totally worth every penny. Since getting it fixed, that annoying engine control light has completely disappeared and the car starts like a charm every single time. I've been trouble-free on the electrical front for months now, no more gremlins to report! Just make sure to keep an eye on those connections every now and then during regular maintenance. You know how these older BMWs can be, they like to keep us on our toes! But honestly, once you get these basic electrical issues sorted, they're pretty solid cars. If you notice any new warning lights or starting issues, definitely get it checked early. I learned that lesson the hard way, waiting too long can turn a simple fix into something more complicated. But sounds like you're all sorted now, which is great!

Thanks for all that detailed info! Really glad to hear it's been smooth sailing for you since the repair. I actually just got back from the mechanic yesterday, they charged me 180 Euro for basically the same fix. Like you said, bit pricey but totally worth it. The starting is perfect now, even on cold mornings. The mechanic was actually really decent this time, way better than my last experience. They showed me exactly what was wrong with the cables and even gave me some tips about checking the connections myself every few months. After all that drama with the previous shop, it's such a relief to finally have this sorted. Makes me feel better knowing you haven't had any issues since your repair. Mine's running like a dream now too. Really appreciate you taking the time to share your experience, saved me a lot of headache trying to figure this out!
