E90 330d LCI n57 engine Oil leak

faraz4271 · 02-17-2019, 02:56 PM

Hi guys,

I'm new to this forums, I have a 330d 2009 automatic. Noticed oil leak although said as minor on MOT. Didn't think much of it but now it has leaked from full to 3/4 in a month on Obc. I got it washed from underneath and tried to see where the engine leak is coming from.
Is there anyway to see if it's the oil sump gasket , oil filter gasket or something else.
Anyone had similar problem of s leak in the past? Not sure what's the best to go about it. Dealers want 240 jus to look at it .

Look at the engine in those areas. That's all.

You could also check your turbo oil lines.

Also had an oil leak on my N57 30d a few years ago, it was the filter housing gasket.

I have just purchased a 2006 e90 330d and have a leak from oil sump and also gearbox sump. Heard its quite an expensive fix
