So long story short, I had both rear brakes lock up and stay on for an extended period, I posted about it awhile back and figured out a path forward (I thought). Anyway I would leave car alone for awhile and things would go back to normal, never any warning lights except "brake linings"--no duh! Anyway took it to a good indy benz shop and they verified that ABS module/pump had issues.

I got rid of that pump and swapped it for one off ebay (its an ASR unit but part # isn't quite the same), worth a try. Now I have all the fault lights I could dream of all involving traction and the brakes. So I go back to the benz shop they get this code after clearing all codes C1310-000 A7/3YF8. This supposedly means "front axle switchover solenoid valve" --cable could have open or short circuit.

What does that have to do with what got me here? I guess I have no choice but to believe the code given, but that had nothing to do with what got me to this point, should I suspect this new used ABS pump since I did not have any of these codes (except brake lining wear) prior to installing it?

Somebody help me please

May seem trite, however I have issues with my tooth brush, but I don't think about change until I find out what was wrong------just for curiosity what were the original faults.

What is the old and new part number? What is the VIN of your car!!

 

Hi Plutoe, I remember an equally famous quote of yours from the last thread I posted

"FYI you are about to embarke on a very expensive adventure that at this point is based upon hearsay----do your self a huge favor and find a shop with factory equal software and have the module tested---if I was going to spend 800 to 1000 bucks I sure as S would want to know beforhand the problem and fix.

So whats an extra 75 bucks!!"

So $265 later (yes I need a new mechanic consultant), they found no pertinent codes, he has pulled codes the last couple times I've been there, so I assumed he did this time as well. He concluded that the ABS module was at fault, some mechanical passage within it (He flushed the lines etc.), so I acted on his advice and swapped it. I had no warning lights prior to the swap other than "brake linings"

Here is what I've got (hopefully the parts are compatible):

VIN WDBJH82F8WX003269
Original ABS pump: A 210 431 00 12 (ASR)
New used ABS pump: A 003 431 30 12 (ASR)

Thanks for any assistance!

 

I do not have the engineering experience to make the call, however what I can confirm is the followingFYI you gave serial numbers not part numbers, see corrected parts)

Part 210 431 01 12---only used on models 210.082 and .282(yours)

Part 003 431 31 12---within North America used on 210.065 and .265

What's the difference-There must be a difference as MB does not typically have different PN for the same part, but I do not know!!!

FYI the part is called a hydraulic unit

 

There certainly isn't any fitment issues, they are both asr units same line locations, same multi pin connector, although I will look closer at pins tomorrow. I did install component with battery connected which probably wasn't smart but....

Thanks for your help, I guess I'll go fishing for the exact same part #, foolish but I thought it could be flashed or something and I'd be good as gold

I think I'll forget about the other fault code for now right? It wasn't a problem with the other unit in place.

Cheers
