So my abc drive carefully warning light came on in red and i was wondering what is my first step to trying to figure out what i should replace ?

Should i take it to the dealer ? will they give me the diagnostic codes ? Should i goto mbstartool.com and buy a diagnostic system there ? which one would i even buy though ?


I kind of want to go in there and just replace then tandem abc pump but what if its the actual compressor ? what if its none of those things ? could be a vavle block or a accumulator.

Any help and suggestions would be much appreaciated. Im not scared to rebuild the abc pump if i have too which seems like thats usually the case. My fluid for abc doesnt seem low at all.

Dear Biff, your solutions go from the foolish to the absurd,and wow I wish I had your money to throw around----do yourself a huge favor call around the foreign repair shops and simply ask if they have diagnostic tools that can read all of the cars modules---someone in Houston has gotta have good diagnostics---then go see him and all you want is a copy of the quick test,which lists all the faults and then you can play mechanic and attempt to fix a very complicate system!!

you absolutely need a mechanic with the star/SDS computer system as it's the only way to read abc faults and run tests on the system

don't start replacing parts. While it's usually the pump it could be the valve blocks or a strut

Since I plan on owning a mercedes benz car for a while i really dont actually mind learning how to use a star sds over time. Ive had my eclass for almost 10years now and ive never taken it to the mechanic ive always fixed it myself.

I see a bunch of dirt cheap s classes on craigslist. I think it would be awesome to learn how to repair these vehicles over time so I could buy one,fix it and give one to my mom. So im looking at this from a long term point of view. I think i have a guy coming over this weekend who does side work Ill ask him which system I should look into getting or not.

If anyone can still recommend a system to buy please chime in

I have the aliexpress setup on XP that works very well. The new ones use W7.
Tiny curve with keygens and a larger curve learning the system.
Anyway, real happy with the aliexpress quality.

Any sds will work. ABC system seems complicated at first but it really isn't as bad as many make it out to be.

hey if you want to work on ABC system you definitely need star diag. i have this set up and it works like a charm http://www.ebay.com/itm/For-MB-Star-...-/152011329608 and i had same problems as you did with ABC and my pump was shot so i did rebuilt it but be careful what u getting in to there is a very good write up on here that i used to rebuilt my pump they are very expensive good luck to you sir and keep as up dated ......... and i will try to find the write up for the ABC pump rebuilt and the rebuilt kit is cheap also i belive i paid around 100$ for it

i took it in for a diagnostic and it was the pump. i just ended up letting the mechanic do it.

pump,serpentine belts,hydraulic fluid,filters-3,200

even though it was a costly repair the dude had mercy on me lol so i feel i got a very very very good deal at the end of the day

$3,200 is full retail. Brand new pump from dealer or reman?

Ouch! Any time I get an ABC car I will immediately flush the fluid with MB fluid (pentosin will eventually kill the pump because there are no conditioners in that fluid), replace the filters, and replace all 4 of the pressure accumulators (also known as nitrogen spheres) under the car. I will do all of that even if the owner tells me he just did it an hour ago before I came and bought the car. Can never be too careful, and it's not that expensive and you can do it yourself.

That usually alleviates a lots of stress off the pump and will save a dying one from death or bring one with error codes back to life (most of the time). I haven't had to replace an ABC pump yet, and I have had 4 cars with ABC that I beat the absolute snot out of.

Huh? Mb fluid IS pentosin chf11s just in a relabeled can !

It's actually mildly different. Even if you pour it out on a paper towel right next to each other you can see and feel the difference between the two.
