163K miles, SES light has been on and off for a little while and I ignored it for too long. Finally got around to pulling codes and found lots of them. P0313-misfire cyl 3, P0183 fuel control limit bank 1, P1085 fuel control limit bank 2,
P0171 lean bank 1 and P0174 lean bank 2. Car ran fine with only a slight "lope" on cold start for 3-4 seconds then everything was great. Searched lots of sites and the consensus is a bad MAF sensor. Rolled the dice and picked one up this afternoon and installed it and immediately the SES light went out. Thank God for the internet! Now I have to go after the right front wheel speed sensor that has the DSC light on (code 006). I have neglected the girl for too long and it's time to get her back in shape.
Finally got around to doing the wheel speed sensor but the DSC light is still on, damn...Have found lots of info on the trio of DSC ABS and brake warning lights but not much on just the DSC warning light. ABS works fine but traction control does not. Speedo and cruise is also fine so i am stumped. Looked at module masters web site and read on the needed rebuild of the controller but I keep thinking since everything else works fine the odds of the ABS/DSC controller being bad is low. During this whole mess I accidentally hit the rear shade button next to the DSC button and the drivers side pivot broke. Ordered the aftermarket aluminum pivots yesterday and will get to that project this weekend. I hope to find some tips on the DSC issue from all my friends here.
Well, sh*!, the SES light came back on last night! Gonna have to pull the codes again and see what the old girl is up to now. Thought we were good to go for a while but apparently not, it's been 3 weeks with the light out and all seemed to be well. Almost 165K miles and she is getting temperamental and bitchy. Anyone ever had a new AFM go bad after 3 weeks???
SES light went off last night and has been off all day. Quickly took it in for the dreaded California Smog Check while the SES light is off so I can renew the reg. Gonna have to buy the scnner software for my laptop so I can see what's going on.
WTF??? The SES light came back on this morning. On, off, on off. Never seen anything like this. I am not getting much response here so apparently nobody else has dealt with this issue. Thought I had it all rapped up with the AFM but obviously not. Since I don't have a scanner, I will have to have the codes pulled and start all over. Damn...
I would recommend the BMW Carsoft software. The required cables are available off Ebay for a reasonable amount. The software can be found as a free download. All you need is a laoptop with a serial port.
After ONLY 6 months I think I finally have this one solved, bad #3 cylinder coil. Had a P0313 misfire code with P0171 and P0174 lean bank one and two codes. Never did feel a missfire but apparently the whole thing is related to the coil. Weirder still is that I replaced that coil more than a year ago when I had the same po313 code but must have bought a bad coil (what I get for buying a cheap Kragen part). Scanner showed short term fuel trims above 10% so I have been looking for intake leaks but found none. Got me a good Bremi coil and put new plugs in while I was there and the old girl is back!
Recently have had the ABS and Brake warning lights coming on and the speedo being inop when the car was hot in addition to the DSC light that has been on for about a year. Decided its time to remove the DSC controller and ship it to Modulemaster. Three days and voila' all is well. All the codes were phantoms. Speed sensor and abs pump codes were not real, just the DSC acting up. $324 shipped to my door and we are back in business.
Good to hear you got it fixed. My friend was having an issue with the ASC light and ABS lights illuminated on his dash. We fixed them the other day by swapping out the ASC and ABS relays and the lights disappeared.
The issues with the old girl continue. CEL back on and a little oil leak and a rough idle on cold start. Turns out the CCV return hose broke in two. Opened up the crankcase, which BMW's do not like at all and also caused the oil leak. $30 and we are back in business.
