Mein Auto: BMW 318i Auto 1998
New Member - Hi Everyone and yes you guessed could do with some advise.

Hi Everyone,
Lucky Me.
I've inherited a BMW 318i 1998 (E46 I believe but this forum claims 1999 for the E46).
It's a cracking motor in great nick, but with its age comes a few problems. I'd like to think I am capable of a bit of maintenance so have been working my way through some of the problems. So far I have replaced the rear discs (inner drum was shot so no handbrake) and rear wheel speed sensor (had to drill the old one out), as the dashboard was like a christmas tree and the speedo was not working.
Can anyone answer the following please.
Fuel Consumption is currently at 30mpg but seems a bit sluggish on acceleration. I have disconnected the MAF and there is a difference which shows the MAF is working (No kickdown with MAF disconnected). I still need to check hoses for cracking and airleaks (when it stops raining), is there any checks I can do for the 02 sensor please ?
Additionally I seem to have a leak both on the front passenger side and drivers side. Each seem to have 2 sources. One appears to be through the drains of the drivers door and the other appears to be somewhere from the Inner/Outer Wing area which neverously drips around the Glove compartment fuse box. Any suggestions on blocking off this leak would be greatly appreciated.
Many Thanks
Raggedy

02 sensors with over 120,000 miles on them should be replaced, they`re usually pretty well gone by then....

The leaks you're noticing by your doors are most likely due to old vapor barriers. There are a handful of instructional videos on YouTube that you can reference. Just be sure to disconnect the battery beforehand. Other than that, it's basically just removing simple fasteners and eventually interior panels. Keep us updated!

Forum is written for USA models, so we'll call you an e46!

Could be failing fuel pump for sluggishness. Next step will be to get stranded somewhere. Check out replacement vids.
And use www.furiousmethod.com for price check comparisons here in the US.
