Well, 1st of all welcome to BMW "Ownership/Poor-house"!! I bought a used 2000 BMW E39 540i (Man Date: 10/99) M62 a few yrs ago now, for around $5,000 CDN and I've probably spent another $6,000 just in used and new parts.
If you go junkyard hunting and can't seem to find any M52 or M54 e46 320, 323, 325, 328 cars or an 528i that still have their MAF, scan the yard for a Hyundai. Lots cheaper than the "for BMW" alternative if going new. Korea was selling through US ebay for awhile too, at about that price. I bought mine new, paid about $90 for it, but it was from a vendor on ebay. Siemens part # I forget but I believe it's practically identical maybe with an extra letter at the end. I've been running a "genuine" Hyundai part in my car, with no issue. If going used, junkyard 2.0, 2.3, 2.5, and 2.8 liter M52TU and M54 engines in the e46 cars apparently use the same Siemens MAF, as does the Hyundai Sonata 2000-year model with the V6. On the MAF, should you decide you want to replace it. Now a bit wiser, I realize there's no such thing as a deal along the I-5 corridor. I overpaid for mine 8 years ago, but in my local market that was still cheaper than Honda Accords of the same age and mileage, so at the time I thought I was getting a deal. $1200 for one of these? I'm in shock but I guess I shouldn't be. I'll try to clean the connectors and the MAF. They won't knock the car into failsafe but a bad throttle body or MAF can.Yes it went into failsafe. Your last two codes have to do with the secondary air pump (SAP). They won't knock the car into failsafe but a bad throttle body or MAF can. You can try cleaning the sensor inside your MAF with a MAF-specific cleaner. Take a look at about the eighth photo down, at the following link.

Sometimes it's that connector that's causing the issues, and sometimes people who remove throttle bodies don't know how to reset and properly re-attach the connector. One thing you can try with the TB is to unplug it from the harness, "reset" that round connector, spray some contact cleaner on the connector and socket pins, and reattach. If you got the car for a steal, good, because with almost all used e39s you need to budget a couple grand to get them back into reliable running shape. It's not really that these TBs are exceedingly sensitive, it's that they don't need much to be pushed off the cliff when they're old and on their way out. The pots inside are fairly well sealed and require taking the TB apart just to reach them and try to clean with a good contact cleaner. IShipwreck, one day of ownership? Did you also get bumped into engine failsafe mode when the throttle error happened?Īs far as I know, the best you can do with the throttle body errors is replace the throttle body with new or a used one that's still working.

If that's a 2000 model-year 528i, the throttle body is the hybrid version (DME control plus physical cable) that has a couple of potentiometers inside, no separately replaceable TPS units. Is there any place online that you guys go for parts? Anywhere you can recommend me to look? Are the TPS's I'm finding actually fit and they are lying to me saying it won't? idk I have no idea where to get a replacement TPS that fits. When I go to auto sites and manually search, nothing "fits" my car or they don't have any Throttle Position Sensors. I tell google what I want, google doesn't understand and gives me TPS for 600 other BMW's or randos. However, I can't find any replacement TPS for my ride. I already checked many sources and the first thing I want to do is test and possibly replace both the MAF and the TPS as well as give the throttle body a good cleaning. I believe it was a steal for how much the guy was selling it for, but I suppose with this first round of repairs, only time will tell. So far I love the thing and I've only driven it once. Hello! First off I JUST bought my very first BMW yesterday! I know I know, thank you! I appreciate your support.
