Hello, i have a list of problems on a recent bmw purchase, it's a 2006 bmw e61 530xd pre lci, would love to fix these problems but have no idea the source of them. Don't have an OBD tool so need to go off advice.
- The level control system works fine but there is still an error, both sides rise and there is no leak in the bags, the compressor works well too as i can hear it working.
- The brake lights don't work either although the back lights work (the inner red lights) i have replaced them and the error keeps poping up, i have a 12" subwoofer in the back and that might've broken them but i tried replacing the lights and then not using the subwoofer, but the error still pops up after a while, is it broken wires? I have checked the fuses and they aren't burned.
- the biggest problem is the engine leaks oil, the motor is a M57TÜ2. it seems to be coming from the front of the engine and a point on the right side of the engine, here are some photos
(in the middle of the photo in the dark spot is a buildup of oil, no clue what the part is)
I'm not sure where the leak is coming from in photo 1 and 2, but are there any parts where oil circulates in the front of the engine? I'm thinking there is a gasket in the front of the engine where its leaking from.
- and last but not least the diesel clouds, when i accelerate and my rpm exceeds 2,500-3000? rpm a diesel cloud appears, it gets thicker and thicker until the rev limit, there are no egr valves as it has been tuned to 300hp and there doesn't seem to be a noticeable power loss. Is it the dpf? or is it running rich?
Would love for some advice, im quite an amature with my car still and would like these problems fixed before my next stately car check or whatever it's called. Thanks a lot!
