I wish that there could be in Giant Letters near the top of the forum where it's plain for all to see ,,when asking questions about check engine lights-- have the codes read before posting here (or elsewhere) what thier check engine light is about--- how many different
codes are there for the BMW__a few hundred

We can probably assume that those that ask either don't have a GOOGLE search box in their browser (or didn't think about it)...nor have they ever typed "BMW OBD II Codes" in an internet search. If they had, I have no doubt they'd see a link to a site that lists ALL of the OBD II codes...and even breaks down some by car mfg. Doing a google search for OBD II codes usually puts the link to that site near the top.

Those same people (some, not all) probably have not taken the time to educate themselves as to what the CEL/SES warning light actually means...nor that OBD II codes are basically "universal" emission system codes that all car MFGs had to comply with (here in the states) starting in 1996...and later in some other countries around the world.

Some forget that just about all the information in the world is right at their fingertips (the internet/the world wide web/etc)...and just default to being spoon fed information from those that the trust here on the forum. :)

I agree we SHOULD have 'something', as Poolman suggests, to POINT people to who do ask (since they will inevitably ask).

FWIW, for efficiency, I 'had' started, long ago, a cut-and-paste response to the classic "CHECK ENGINE LIGHT" question ... but I never formalized the process.

Here is that cut-and-paste response I wrote in post #44 (http://www.bimmerfest.com/forums/showpost.php?p=5734933&postcount=44) of the bestlinks back in December of last year.

It doesn't matter to me 'what' the cut-and-paste response says, per se; what matters is to make it efficient for us to point users to it (somehow).


CUT-AND-PASTE TEACH-to-FISH RESPONSE (written for this thread) (http://www.bimmerfest.com/forums/showpost.php?p=5736923&postcount=4) FOR YOUR TYPICAL DTC QUESTION WITH NO DETAIL:

You must have your diagnostic trouble codes read!
It makes no sense to say "My SES/EML/CEL is on or is flashing and my engine is running rough ... what is the problem?".

Before you ask this type of question, you need to do at the very minimum, three things:


Have your diagnostic trouble codes (DTCs) read
Google for what those DTCs indicate on the BMW E39
Attempt the solutions found from that googling effort

If, after performing those three tasks, you haven't solved the problem, then feel free to post for additional help.

When you post for additional help, you need to do three things:


Post the PCodes you found (actual and pending) & the description (nobody memorizes these things)
Describe what you found in your search (i.e., what other people did when they had the same codes in the same model)
Tell us what the results of the diagnostics you ran (i.e., what happened when you did what the diagnostic threads told you to do)

Additional advice:
In all USA states other than CA & HI, your local AutoZone auto parts store will read your DTCs for free; otherwise, for $25, you can purchase a DTC scanner to read your own codes.
- Cheapest CAN OBDII scanner on the net that reads DTCs, pending codes, & clears codes (http://www.bimmerfest.com/forums/showthread.php?t=478610&highlight=alternator)

Here is a list of so-called BMW-specific diagnostic trouble codes but beware; BMW P1 DTCs are computer specific!
- All OBDII codes, including BMW-specific P1xxx DTCs specific to the engine computer of each BMW (1 (http://www.bimmerfest.com/forums/showthread.php?t=510936))



EDIT: I just added a link to the bestlinks so we can refer people to THIS thread!
- Where to point newbies who ask why their SES/CEL light is on but who don't post codes (1 (http://www.bimmerfest.com/forums/showthread.php?p=6411813&posted=1#post6411813))

For the record, I pointed a newbie with two posts here just now who asked:
- yellow check engine light (http://www.bimmerfest.com/forums/showthread.php?p=6470152#post6470152)

How worried shoold i be that my check enginesoon yellow light just came on?

To respond to that specific question above from "Ultraman 68", if the yellow Check Engine Light (CEL) or Service Engine Soon (SES) light is not blinking - then you worry less than if it were blinking.

If it's blinking, that's telling you that an (expensive) emissions component is likely being damaged, even in the short term.

If it's not blinking, then there is probably less chance of short term damage.

What you should 'worry' about if the SES is lit is:
- Something is not working right in your engine
- You are probably getting lower gas mileage and/or drive-ability or performance (which could be a safety factor)
- You can't pass annual inspection in most states

The solution to your problem is the same as described above:
a) Get the codes read
b) Do the requisite research
c) Ask detailed questions only when the research fails

Here is what Saint Q offered the OP in the thread mentioned above (which I post here to leverage his answer to the next person who asks):

... if you have a warning light come on and you don't really understand what it means...the first place you should go is your owners manual for an explanation.

If you don't have an owners manual...you can download one in PDF format directly to your CPU so that you can have 24/7 access to the information it contains (plus it's much easier to search).

You can also find manuals at the bottom of the left column at www.e38.org/e39 (http://www.e38.org/e39) . If your model year is NOT listed...then download the manual that is CLOSEST to your model year...you won't miss a thing.

Here, by the way, is the 'drive cycle' that determines when the lights go on and when they go off. More information is in the reference threads:

how many different codes are there for the BMW__a few hundred

To anyone reading this thread, the codes are NOT universal. They are engine computer specific.

But, a LOT of them overlap.

Here, by way of example, are some of the Pcodes for my particular engine computer:

In a single-cylinder misfire thread today, someone asked:
Is it bad to drive if the SES flashes?

And, I gave the simple answer (which is really all I know):
Yes.
A flashing amber SES means expensive things are being ruined.

But, since I've never had a flashing SES, I've never researched it down to the next level of detail. Looking for /flashing SES F3 or /blinking SES F3 in the bestlinks comes up relatively blank, as does the Poolman pointer thread:
- What to tell newbies who ask why their SES/CEL light is on but who don't have DTC scan codes (1 (http://www.bimmerfest.com/forums/showthread.php?p=6411813&posted=1#post6411813))
Which only says this little bit:

Searching E39-only threads with "flashing" in the title, I find only these three:

Skimming each of those threads, I don't really see any decently detailed explanation of the cause and effects of that flashing light, other than the obvious (catalytic converter damage due to a rich mixture); so, I ask here ...

Q: What should we tell someone who asks the question of "is it bad to drive with a blinking SES"?

Another one today:
hi, today i went full throttle in 3rd gear ( i think ) i was going around 50 mph. once i got to a dead stop the car was idling rough and the SES light came on. can anybody tell me what the problem is? thanks

To which Q kindly responded (among others):
Possibly...if you have an OBD II scanner...plug it in to retrieve the P code. The whole purpose of the OBD II federal mandate (since 1996) is to allow for a standard across all car mfgs for electronic engine emissions.

Since your SES/CEL/MIL light has illuminated, it means that a code has been registered...so any OBD II scanner/reader can retrieve the code and point you in the direction of the senesor that set-off the code.

Not sure if LA stands for Los Angeles (the city) or Louisiana (the state)...but if it's the state & you don't have an OBD II scanner/reader...you can take your car to Autozone or most auto parts stores (PepBoys/O'Reillys/Advanced Auto/etc) and they will read the code for you (for free).

Post back with the 5 digit DTC (diagnostic trouble code) "P" code or google it and you'll be on your way to deducing/diagnosing what caused the light to illuminate. :)

> E39 (1997 - 2003) (http://www.bimmerfest.com/forums/forumdisplay.php?f=103) > Check Engine Light Comes On and Off (http://www.bimmerfest.com/forums/showthread.php?p=8491428#post8491428)

I have had this 1997 BMW 528i since in my family since I graduated from Middle School back in 2003. It's been in our family and been driven here and there without many problems. That is, until about a year or so ago. Since then, the fuel pump gave out, the front passenger side part that holds the tire straight is making it look like the car tire is leaning a little to the side, kinda caving in from the bottom up, its had numerous problems with spark plugs, fuses, etc., and then, to top it off, a traction control off light that won't go away, eventhough my mechanic took the tire off, replaced the arms that hold the tire and all, a SERVICE ENGINE SOON light that comes on and off, and that is what concerns me most.

My mechanic has changed the spark plugs, the actual wires, the bobina/ coil, the tubes attached to the coils, and the thing is, it drives, but sometimes, it shakes, and then when you try to give it gas, it takes a little bit longer to accelerate, sometimes it doesn't do it. But after a while of driving, it takes longer to accelerate and then the SERVICE ENGINE SOON or CHECK ENGINE light comes on and it takes about a day of driving it to go away. We've put the code reader on it and it says that the 1st cylinder is the problem, and so, we've tried to fix it and have done all the fixing above listed. My question is, can it be the fuel injector that is messing up. I'm tired of calling our mechanic and having him try something and then that not be it. I need some suggestions because I just want it fixed so that that darn light doesn't come on anymore and it doesn't shake, rattle, vibrate, or stall when I brake or accelerate. The car needs to get me to school and work at least until the end of this year, and I don't want to be damaging the car by driving it as I am due to necessity.

Any help would do.?
What would you guys and gals recommend?

Thank You and God Bless

This replay may be useful to newbies who keep asking whether this or that is emissions related.
The fact you're still asking that question means you don't understand what has been told to you multiple times.

Let's state it very clearly.

EVERYTHING that causes the SES/CEL is emissions related.

In fact, let's state it even more clearly for you:

If it's NOT emission related, then it can't cause an SES/CEL!

It doesn't matter whether or not YOU (or I) think it's emissions related; it matters only that it lit the SES/CEL.

The CEL/SES is, de facto, an emissions related warning, which, in my state, would fail you instantly.

Let me know if you understand that, or if I need to state it more clearly for you.

That post above was in response to someone who just couldn't get it into their head, even after multiple corrections, that a thermostat code that sets the SES/CEL is ignition related (that OP also kept typing "Wat" for "what", so, I think lack of intelligence is the real problem, but I can't fix that)...

He is resetting the codes. I already know why light on it bc I need to replace thermostat. Does the thermostat have anything to so with emission test?

I wish that there could be in Giant Letters near the top of the forum where it's plain for all to see ,,when asking questions about check engine lights-- have the codes read before posting here (or elsewhere) what thier check engine light is about--- how many different
codes are there for the BMW__a few hundred

...I'm afraid GIANT letters will not address 'root cause' on this problem. What was it that Forrest Gump's said?....'stupid is as stupid does' ;). Ok, that's kinda harsh talk, I take it back - no offense intended towards any Bimmer owner!

Hey Everyone,
I just finished working on the radiator after buying a new cooling pipes/coils. in the process i emptied all of my power steering fluid and coolant and after i was done i placed everything back together. it was on the ramps for about a week. Now when I test drove it, i stopped at a stop sign and all of the sudden it, started to act weird and sometimes it would turn off when I stop. At that time the Check engine light turned on .I checked the temperature of engine its normal(110 Celcius) and battery voltage is 12.8 and 13.1. I researched the problem and most of the answers was and O2 sensor or whatnot. Any ideas?

That's what I had thought, and, for the most part, that's practically true, but, it's not technically true (ask me how I know (http://www.bimmerfest.com/forums/showthread.php?t=510936)).
> E39 (1997 - 2003) (http://www.bimmerfest.com/forums/forumdisplay.php?f=103) > Weird question ... Where are ENGINE-specific BMW P1xxx trouble codes anyway? (http://www.bimmerfest.com/forums/showthread.php?p=5814722#post5814722)
it's not our fault it's so hard to figure out something so simple as what a P1624 means on a BMW.

The definitions vary depending on what version of Motronic engine management computer is on the car. NOT the engine....some cars may have the same engine, but depending on year or model, a different Motronic engine management computer. You really need the Bentley workshop manual to know for certain, what you are looking at. They have all the P codes broken out by model and year.
There is NOT one single set of E39 PCodes! There are sets all over the place. Specific (variously) to the engine and the date, or to the engine and the transmission and the date. Wow. I never knew it wasn't as simple as a single table! Lesson learned. No wonder when I researched P1624 I got hits for a variety of DTC descriptions!
These "BMW PCodes" are "computer specific", i.e., you have to look 'em up specific to your engine, transmission, and build date. Conflicting information exists depending on which table you look up.
The key point you have to realize was that BEFORE I opened this thread, I had only seen "P0" codes on my E39. These SAE P0 codes apparently are pretty darn standard ... such that, almost any BMW search found what the P0xxx code indicated. The hurdle I had to cross in this thread was that P1 codes are VASTLY different in specificity than P0 codes!
..., the "DTC explanations" are not model specific, nor even BMW-specific. They're not engine specific (per se). They are computer specific.
The attached list cross references BMW fault code to DTC P code by module, engine and start to stop date.
etc.
