Hello, My German is not that good so I will try to post it in English and hopefully it will work out. In May 2020 I bought my first car in Germany, a BMW e91 from 2008 October. It is the facelift model. Unfrotunately I didn't check the contract properly and the private seller was able to add clause that there is no guarantee or return rights. after driving it for about 800 Kms I took it for inspection as it had a Service light for a couple of weeks.
on 25.06.20 during the inspection the workshop told me there is an error in the system 30c1 - Motoröldruckregelung statisch. They guy said this is an expensive issue and most likely the steuerkette needs to be replaced and may cost from 1500 - 2000€. The error first came 600 Kms before, so I already drove that much and there were no issues. Now after going to a few mechanics no one is sure what the problem is and the error doesn't come regularly.
Last week a freiewerkstatt mechanic took out the oil and told me there was 2L oil less in the car, it should have at least 4.5L oil. He put in new oil and filter and told me maybe that was the issue since there is no noise in the engine which will indicate steuerkette issues.
I am not confused and want a second opinion, is it possible that due to less oil the oil pressure is a problem? I am trying to drive it more this week and check for the error again.
One more thing, since I found out about the error I didn't drive the car at all, and after 10 days when I took it to a mechanic I saw red oil light for the first time, it went after i started the car again. Not sure if its related. The only issue I have with the car right now is that in first gear it has some missing, the engine vibrates and needs more gas, everything else is fine and the car sounds fine too.
Any suggestions and feedback will be really helpful.
With this problem, parts have fallen from the slide rails into the oil pan and are sucked in by the oil pump. To check this exactly, the oil pan must be unscrewed.
Hi, i think if there aren't any noises to hear from the engine the chain is okay. sometimes the part for regulating the oil pressure is damaged so it doesn't work correct. this may cause the error message.
when the red lamp showed up, was the engine running or not? it is normal for a few seconds(1 or 2) because the pump has to begin to get the oil pressure on a higher level.
it is also correct what the guy before me told you.
Thank you very much for the support and help. I will drive the car a little and then go to the workshop to check if the error is back. If it is then I will ask them to open up the oil tank and check for plastic pieces. #FingersCrossed.
