david888, Glad it worked out for you....

Yeah I know, I've been driving with my steering angle sensor on for a couple years. I tried to clean it too but it didnt work ...I guess i will get a used one cos the new ones are way too expensive ...

Anyway, I have a gas leak hahahah dude, these 5 series are crazy...after 120K miles, everything just falls apart...

Now, angle sensor has bee relegated to the back burner and I'm thinking of replacing either a feed line or even a fuel filter set...

Did you narrow down the leak? Were is it coming from?

david888

Yes, I likely did.

Since the leak (and the fuel smell) was coming from the left rear side, it had to do with the fuel filter. (I was thinking about the charcoal canister at first but one mechanic said, when the canister goes bad, there is no leak, but mine had)

So I removed the back seat and got to the fuel filter and it looked exactly like this picture https://bmwtechnician.com/2016/02/06/e60-fuel-leak/

So I've noticed hair line cracks on top of the fuel filter and they were obviously causing the issue though I thought it might have been the rubbing seal. So I went to advance auto parts and bought "JB Weld 50133 Plastic Bonder 25 ml". Patched all the hair line cracks with couple layers, especially the ones on the bottom of the plastic nipple. Let it dry for 4 hours, turned the car on, and no leak. Drove to the gym and work today and it looks like it doesn't smell anymore.
I would still have to replace the fuel filter becuase it's old and I just dont think JB weld will hold it well.

Let me know if you have any questions. Would be happy to answer.

An update! It's leaking again lol Apparently, that JB weld couldn't hold the fuel pressure and and the fuel ate its way. My filter has arrived so I am going to replace it
