Hey........I have ordered and will be here tomorrow a:

Autel AutoLink AL319 OBD II & CAN Scan Tool

I could swear in the last few days someone posted a link to a list of ALL the codes for a 320. All of this code business is new to me but I have the elusive BAS/EP light and for sure it isn't the brake pedal.......So, after figuring what to do I am going to break down and get a code reader so at least I can have that to come on here with for you guy's help.........

I have searched the threads in the last few days for what I thought was the link mentioned above. Anyone know what I am talking about or know of a link or list where I can get ALL of the codes I might come up against ..........Thanks..........God bless..........Dennis

Hey I got the Autel 319 device yesterday. Thanks for all of the thoughts, lists and replies guys..... Tried to get the thing working last night following the directions to register/update.......complicated and surely didn't do what the little owner's manual said it should........
Kinda funny actually for this ol boy. OBD, TDA, and who knows all the other little terms one has to figure out..........

Question is, can I , should I, be able to plug this thing into the plug on the car and up will pop codes that indicate faults?????????
lol...really God blessin you on this one.......Dennis

Yes it should just plug into the OBD2 port under the steering wheel near the bonnet release catch if I remember right (I'm not near my car at the moment, so I cannot post a picture)

However, I do drive on the PROPER side of the road :grin:(i.e. RHD car) so I don't know if the location differs or not on LHD variants - I highly doubt it but you never know

I am pretty sure I can find the plug; I guess what I am wondering is what will show up on the panel on the instrument............Yes, I guess I should just do it; but have not had a chance yet. Have read and reread and tried to follow the owner's manual to do "setup" but nothing works like it says it should and can't get the website to go my way either..........lol....no I don't have a smart phone, nor use facebook/twitter, or have ever played the lottery.....I kinda can do this stuff if it goes right; but NOT when it is "tempermental">>>>>so a brief note to advise what might or should happen would be great

OK.....warmed up to 22 F today so went out and moved the car out in the sunshine.....Got down on both knees, arthritic, and twisted around under the steering wheel. Mr. Noob, you are right, the plug is just inboard from the hood release......The plug of the test instrument went in real nice, it fired right up, told me the engine isn't running, and when I did start the engine the machine began to test the vehicle just fine.....Then it told me all kinds of stuff that even though I don't understand all of the obd, dec, lgj, and on and on, I do understand that I have no errors.......I got the durn device to test for the "famous" ESP light coming on. Wouldn't 'you know it that not once did the light come on. Drove it perhaps 20 miles and NOTHING.....OK one of these days it will and I will need all of those numbers you kind folks have given us......God bless......Dennis

I started off this thread by explaining that I had the dreaded ESP light on and was getting a:

Autel AutoLink AL319 OBD II & CAN Scan Tool

I ordered it hoping that it would indicate the codes that need to be tracked down and then the repair to whatever caused the fault.................

NO CODES........NO CODES........NADA......NOTHING

The light is very intermittent and is temperature related....When I drive it on cold days, no light. It only comes on when the outside temp is above 60.....MAYBE......MAYBE NOT.........

NO CODES....I finally got the light to come on and it stayed on enough for me to hook up the device........NO CODES.......

Is there some trick to hooking up one of these things....should the car be running????.......I have fooled with the device and everything is working on it. It runs tests and all.........

Is there something I am NOT doing????????..........

At least we are getting a pretty good library of all the related codes to the ESP/BAS................God bless.....Dennis

I have a couple of OBDii readers and I have the ABS & BAS/ESP lights on.
The ABS is code C1101 and at the German shop I use, that's what it threw up.

The other code, that "may" be related, is C1140. Depending where you look, you can get a different explanation of it. My man's system says its steering wheel position.

As the ABS and ESP use the same wheel sensor, there's a good chance the sensor will fix both.

Dunno about the C1202 I have. Seems to point to the rear circuit sensor/pressure switch on the master-cylinder. Again, it may be related to the wheel sensor.

I took the caliper/disc off and cleaned the reluctor with acetone spray and a sonic toothbrush:grin:
Waiting for the sensor.....................

Test your passenger side front wheel sensor. They seem to give up regularly. Probably through work-hardening of the wires, so it can be intermittent.

John..Fanfreakingtastic .........Proud for you BUD......I am gonna take a chance and try to figure out the sensor business.....I still get no codes showing up on my code testing device; but the dash light comes on.......I think there is nothing wrong with the Autel device as it runs tests and shows how things are working.......

.NO CODES........so....I have no idea what the sensor looks like.........How would I test the sensor??????????.....God bless.....Dennis

Ohm meter (multimeter function). I took my sensor off and tested it but you should be able to just disconnect it from inside the wing. Set the meter to ohms (Ω).
The sensor has polarity so you wont get a reading one way. They should be in the 800-1600 range, but most important is that the reading should be obtained and stay steady (within 1-2). If you test it and the reading climbs, its toast. If the reading is too high or too low, toast. Look on Youtube. there are several vids of testing.

I could not get any readings on my reader. Had to take it to the shop. An independent will charge you less... takes 5 mins.

Best of luck

My sensor looks like this:

You are totally a HERO John.....Plugged in "Testing BAS/ESP sensor Mercedes ESP" in a search engine and up popped many gazillion videos and articles. So, it's rainy day or nothing to do at night research time for awhile......

I still wonder why I get no codes on my Autel device. Should I be getting an error code or just keep on searching blind like testing the wheel sensors will be????.........

Another question. With this being so intermittent and no problem, so far, surfacing, where is the relay the BAS/ESP light. In one post a fella says it's a black box on the passenger side of the firewall and another discusses replacing his which is under the storage compartment in the center console......but no year nor model is posted so am not gonna go tearing into mine without exact information.........and have you ever checked out all of the black boxes on the firewall?????.........

What I would like to do is find mine, unplug it, clean up the connections, and then see if perhaps it is just a bad connection.........

So...WHERE IS THE RELAY FOR THE BAS/ESP SENSORS/WARNING LIGHT LOCATED ON A 01 320 SLK????

The relay is for the ABS pump etc. The light will just be powered from the control module, I would assume.
The box containing the K40 is on the passenger side, (2003 200K). The relay was easy to remove and showed no signs of corrosion, dirt or burning so I just replaced it.

From what I have read on the forums, most of K40 related problems were pre-facelift cars. Not 100% about that though.
I would still go down the sensor route if I were you. Cheap and simple to do and if it fixes it, the jobs a good'un :wink:
