Ha, juz chyba trafilem na przyczyne. W B48 czesto peka wezyk odprowadzajacy plyn chlodzacy do zbiornika wyrownujacego (17129845173, 17128677244, 17128740118, 17125A05950, 17128616536) - BMW robi go ze slomy lub z drewna ;) - dlatego peka. wylewa sie wtey caly plyn chlodniczy i to nieistotne ze natychmiast zaparkujemy auto - i tak trwale uszkadza to glowice- ja przejechalem 30 metrow tuz po tym jak zobaczylem komunikat na komputerze. I umnie bylo dokladnie to samo po wymianie wezyka uzupelnieniu plynu i odpowietrzeniu ukladu - dzwiek sie pojawil :( - B48 od tej pory brzmi jak dizel :( Nie mam gwarancji ani pomyslu jak to naprawic - nie wydajaz zyliona cebulionow w ASO.

cytuje: DaDaoChen 2 miesiące temu I have the same noise too, after bunch google search I found one post on Reddit, the owner took to BMW dealer and they replaced the cylinder head. I'm not 100% sure if that's the real cause, however that's what bmw did. Something to do with internal baffle of sort. Sounds like a build in PCV failure. Which requires cylinder head replacement I'm assuming. Quick question from me for u, have u had the coolant reservoir hose break on u yet? Which caused the cylinder head to deploy all the coolant. If so I think the short time overheating caused warped in something inside the head. Cus I start hearing the noise after my reservoir hose broke ODPOWIEDZ Dani bar1 i bought a used bmw 220i with the same problem since i got it. The pipe you say is broken for me. I don't know if the previous owner had broken it and from then on he started making that noise. Currently my car is at the mechanic as the cooling water was boiling without the car reporting anything. In the next few days I will let you know if the mechanic found any problems in the cylinder head. DaDaoChen 3 tygodnie temu @Dani bar1 cool thanks. Yeah I didn't notice the sound until the coolant reservoir pipe broke, which the engine overheated a bit during it. After I replace the pipe and coolant. Is when I started to hear the noise
