    I have a 2003 330XI with about 148,000 miles on it. I live in Maine. I have never had the "cold weather oil separator" upgrade done as I traditionally haven't driven the car in the winter due to the availability of a pick up truck. I recently purchased a 2015 435i and my son is taking my 2003...

See the pic - it's the bottom wire of the three lower ones coming out of the harness. I can't figure out where it plugs into. :facepalm: Anyone know? It's a...

    Help please! My check engine light came on a couple of weeks back. I used my CarMD (OBD reader) diagnostic reader on my 2003 330Cic and it gave a reading of po174 (only). So I cleaned the MAF and also found a tear in the oil separator hose going to the dipstick so I replaced that hose also. The...

    I will try to keep this as short as possible. I have read all of the stalling/rough idle threads and nearly anything else related to this issue. Overall, I am looking for possible causes for a rough idle due to an oil separator repair. Please note that my car has NEVER had a rough idle, only a...

    Ok I have the PVC valve (oil separator) unit sitting here, for the last few weeks have been too busy to install it and after a bit of reading I want to get the hoses too... Any one have a website address of a legit place in the USA with a fair price for the part? I can seem to find any on eBay...
