bummed

Roger that. I will attempt again tonight. Stand by for results. Last time it took me 1:40. This time I will also remember not to close the trunk with the battery disconnected.

 

Too funny. Those pictures were showing as broken links last week for me but now they work! Guess I will be doing this DIY now for sure this weekend! Thanks to all that responded and being kind.

 

Dude!

Best day ever! Did it again, step by step. No gunk on the disc(because I cleaned it last time), but there was a ton of gunk on the housing that connects to it. Q-tipped all of it out of there.....5 used during the process. Put everything back, connected battery, fired it up. Lights everywhere! Turned left, right.....still lit up. Turned engine off....sat for a minute ....fired it back up. Lights still on, backed out of garage turned on P500, and then off again and blammo! No more lights!!! Drove around the block(driving lamp/bulb decided to go out on me)and all is good. Rock on!

Cool! Once mine went off, it stayed off. Hope the same for you! Definitely better than taking to the dealership to replace a part that isn't broken.

 

Lights still out! All good.

Thank you so much

I did this DIY and wanted to say thans everyone that replied and added to this post. I saved over a $1000 with this. I'm not sure weather I should post more pictures, but took some while doing this to show the air bag release hole, was confused on it for a short bit, and others. Here is a link for the pic ( good for a little bit)

A few more pictures would be helpful. Upload directly to the board, rather than hosting offsite :lightbulb:

 

So I took my car in because it was showing the EDC malfunction light. Dealer ran the diagnostics and said I need to replace my Steering Angle Sensor. They wanted $1100 for parts and labor. I saw the DIY for cleaning the sensor before going with the dealer. I spent a saturday taking it apart and when i finally got to the disk and sensor they were SPOTLESS. and cleaned it up with some alcohol just to make sure. Put everything back together but I still have the EDC malfunction. Any ideas? Why would the dealer say I have a bad steering angle sensor. it looked perfectly fine.

Cleaning the "disk" repairs one common steering angle failure, but like any electronic device there are many other ways it can fail.

 

What I misunderstood.

I thought that 1091 was the airbag hold, but the hole to get to the airbag spring is under the steering wheel imag1092. Also if you look at the picture of my disk, I have sparkle stuff, as well as, the crud on it, which, came off after I cleaned. And yes, I didn't take a picture of it clean because I wasn't sure it was going to work. Sorry. :tonquesmilie:

 

For those of you that have to replace your SZL, here are the steps to code it using DIS:

Diagnosis-> 5 series -> E60/E61 -> Right Green Arrow -> Control unit Functions -> Function selection -> Service Functions -> Chassis -> Steering-angle sensor -> Adjustment, steering-angle sensor -> Test Schedule -> Right Green Arrow

You'll then be guided through the steering angle sensor calibration process via on-screen instructions.

You may also need to code using NCS Expert to get the steering adjustment to work.

 

WoooHooo, just did it tonight and so far so good. I was getting the malfunction DSC and Flat Tire Monitor and some other warning..it was happening each time I drove the car when I took the first turn..
I drove it around a bunch and cranked the wheel side to side, no warnings yet....
Thanks again to an amazing forum...

 

Glad to hear it! mine has been malfunction free since I did it back on May 4th of this year.

Almost succeeded - can't remove SZL

Hey guys,
I love the posts and the photos for your M5 SZL module/sensor repairs. Had this been available when I had my catastrophic electronics failure, it would've saved me $1200 about 3 years ago. I've started having Active Steering problems, and DSC warning lights come on peridically, and more frequently now, about every other day. REcently had an indy mech changed a battery due to other reasons, SMG pump replacement and brake vacuum pump replacement.

Found this and thought I'd give it a try, even though I have a 2005 545i. I got as far as taking all the screws out of the SMZ module, but couldn't lift the darn thing out of the column!! It looks slightly different from all the pics (of course), so I tried just about everything to wiggle that thing out, so I could open up the interior piece to see the goop to clean off...

Since it wouldn't lift out after all the screws came out (wondered if they glued the da*n thing in), I tried to open it up along the circular plastic piece, with all of its plastic tabs. I managed to break one (there's about 6 of them all the way around in the worst locations), and had to stop and put the whole thing back together again, as it's my DD and it was getting late.

What I noticed - it is very WET/oily inside the SMZ module. I HAVE to get inside to clean it, but I cannot figure out how to get the module lifted out!!

Anyone have more clues? I'll try again next weekend to see what I may have missed today - will certainly start earlier on a Saturday morning instead of a Sunday afternoon!

thanks in advance!

 

You must not have got all the clips or screws. Mine came apart quite easily. I'd be surprised if yours was glued.

BTW, a year and a half later, I'm still SZL error free. The cleaning was a fix for me.

 

Thanks - I'll keep looking. I even took out extra screws that weren't mentioned earlier. Now that I can get that airbag and steering wheel off, it should take much less time up front, so I can take photos along the way of where I'm running into problems.

When I try to get the top of the circular module to open up, there's this liquid stuff coming out of it like a yellowish oil... just gotta get the thing out to clean it...

I can hardly wait til Saturday morning, but hoping I don't royally screw it up!

This one isn't mind, but it looks exactly like this one I found on Ebay - seems like the seller had rotated the spring catch to the left side, as mine is horizontal across the top instead...

there's hope, because someone got this thing out!

 

I think I may be suffering with this fault too, but im not 100% sure.

My car will randomly and periodically just not accelerate at all, and the DSC light flashes at me while the car falls flat on its face. It's normally after ive been to fill up the car with fuel and pulled out of the station, but sometimes it does seem to occur just whenever; But I do seem to notice it more after I drive the car, shut it off for a while, and then pull out of wherever ive shut it off and try to get up to speed again.

One other thing its doing is not holding speed on the cruise control. This seems directly related to how fast im going / how much engine power is required.

For E.g I set cruise at 50mph and its fine forever.

I set cruise control to 75mph and its fine until i hit an uphill, then it shuts off

I set cruise control to 95mph (for testing) and it shuts off straight away.

not lights, no errors here, the cruise control just cancels itself completely. It seems that when the car needs to give strong throttle to maintain speed, the cruise cancels.

Any thoughts guys?

 

Argh, I just put everything back together after cleaning... though my disc had no residue or gunk and looked new. Connected the battery, started the car up, the Engine and Brake lights were still on, turned left and right..... and the lights remained on. I decided to turn the engine off and let it sit for a minute before trying it again, but the lights remained on after the second attempt. I'll try it again in a little while longer, but it's not looking promising. Do you guys think that I will need to replace the module?

 

just did this today and took me about 2 hours or so ..... since its freaking hot in Bay Area today ......

Used Nail Polish Remover with Q-tips ....... hopefully they light stays away for some time

 

Hey guys. Just read through all 6 pages. Car in question is my 2008 550i m-sport. I have what seems to be a steering angle sensor problem

1) DSC light on
2) BRAKE light on
3) TPMS light on (this could be a serperate issue though)
4) start off assistance inactive
5) cruise control not working

BUT

All of the turn signals and high beam and adaptive lightning options still work just fine. So would this still be a steering sensor problem. I noticed that on a cold start there are no lights on the car. And i could throw it in drive or reverse and move forward and the lights stay off. BUT AS SOON as I turn the steering wheel...boom, all lights are on.

Does this sound like the steering angle sesor problem?

.

 

Yes ... same issues were with my car ... except no tpms error ... just follow step by step directions nd ur error messages will clear ... good luck

 

I took it all apart and found the disk to be quite clear...just a bit hazy and then on further inspection I noticed cracks radially along the whole disk.

Is it possible to buy just the disk? Probably not, so is it possible to buy a used SZL and then remove the good working disk and install it in my current SZL to avoid having to reprogram it?

 

I cleaned everything and it kept coming back. It turned out to be the bank2 throttle actuator... i think it's about 2k+ to RR.

 

Did you ever try to change out the sensor and what made you change out the throttle actuator? My mechanic said he seen a fault for that but thinks I need the steering angle sensor to clear the faults im getting.

 

Ok I ordered a totally new SZL. it was just under $400 shipped.

I'm just deciding if I should install the new one and pay the fee to have it reprogrammed., or "risk" taking the new one apart and installing the disc into my old module so I can avoid reprogramming.......?

 

Where did you order your sensor from?

 

Great write up. I followed this and have had no issues with the warning lights coming back. Saved me a ton. Thanks again

 

Thank you to the guys who contributed to this thread. Just saved me a bunch of frustrations on a 2007 M5 with 133k that we just put a motor in.

Thanks to ol' jcolley for sending me a link to this as well... Ha

Deposits

Very interesting thread. Does anybody have any idea where the original contaminations are coming from? This optical mechanism is buried away quite deep. The deposits also have different signatures. One of them seems to be salt like crystals from moisture drying up on the disc. Another one has "sparkles/particles" on the disc which leads me to believe that there was some mechanical interference, as in rubbing that caused a wear of sorts. Did anybody notice noises in the steering wheel while turning it, before it went bad? Just curious..... Fixing is one thing; diagnosing and further preventing repeats is another.

 

There is a lubricant that people installs from the factory on the part which sits on top of this one in the assembly. It somehow moves to the optical disc. I don't see a way around it to be honest.

I have about 50 of these things if you want I can send you one and you can play around with it and see.

Thanks. Would be interesting but no need to go shipping around all kinds of stuff.

 

looks like i'll need to do this diy soon myself as i'm getting the dsc malfunction from time to time.
