BMW Parking Heater Dead: Troubleshooting and Solutions

Hey there! I had a similar issue with my 2017 BMW 4 Series (gasoline). Last month, my auxiliary heater acted up the same way, complete silence when trying to activate it. Took it to my trusted mechanic, and it turned out the glow plug was defective, plus there was a wiring harness issue that needed attention. The repair wasn't too complex, but it required some specific diagnostic tools to properly identify the fault codes. The mechanic had to replace the glow plug and repair some corroded wiring. It wasn't a serious issue in terms of affecting the car's overall performance, but it needed fixing before winter. My advice would be to get it checked soon, these heater issues don't usually fix themselves and can sometimes indicate other electrical problems. Look for a mechanic who specializes in BMW systems and has the right diagnostic equipment. Hope this helps with your decision!

Hey! Thanks for sharing your experience! Sounds really similar to what I'm dealing with. I'm actually planning to get it checked next week. Just curious, do you remember roughly how much you ended up paying for the repairs? Also, has everything been working smoothly since the fix, or have you noticed any other quirks? Thanks again!

Hi again! Glad to give you an update! I got it fixed last month and it cost me 440 € for replacing the defective glow plug. Since the repair, my auxiliary heater has been working perfectly, no more silent treatment when I try to turn it on! Honestly, such a relief to have it sorted, especially since it was a straightforward fix. The mechanic really knew their stuff with BMWs and got it diagnosed and fixed quickly. Haven't had a single issue since then, it starts up right away and heats like it should. I know you were worried about finding a good mechanic, but if you find someone who specializes in BMWs, they should be able to sort it out without much hassle. Feel free to ask if you need any other details about the repair! Good luck with getting yours fixed next week!

Hey there! Just wanted to update you on my BMW heater situation! Finally got it fixed yesterday, and wow, what a difference! Found this really skilled mechanic who diagnosed it right away, turned out to be a burnt-out glow plug and some dodgy wiring, just like yours. The whole thing set me back about 520 €, a bit more than yours because they had to replace some extra wiring, but totally worth it. The repair was actually quicker than I expected, dropped it off in the morning and had it back by afternoon. The mechanic walked me through everything they did, which was really reassuring after my last bad experience. Took it for a drive this morning and the heater kicked in perfectly, no more error codes or silent treatment! Thanks again for sharing your experience, really helped me know what to expect. Glad I didn't put it off any longer! Take care!
