i know a lot of 05 Evos have problems with the ACD whether it be bleeding the system or the 3 lights always going on. My problem that i have is that my 3 lights started going on during the early month of December. Checked my ACD fluid and it was all good. Took the negative terminal off, let it sit, put the terminal back on, started the car and the ACD light went back to default. Went for a test drive and about 1-2 miles, all three lights went back on. I did this process for another 2 times and told myself F*ck it due to all the fustration and impatience i endured. Now fast foward to Jan. where i did my oil change, i checked all my fluids and noticed that my ACD fluid had gone done BELOW the minumum line. the only part of the resevior that had ACD was the bottom half of the tank. So i went off to 76 gas station to pick up their ATF and added the fluid into my ACD tank to the full line. After i was done, i drove to work, and back home and that was the end of my day. Woke up next morning and drove to school and back home. When i got home, i decided to check my ACD fluid and what do i notice? The fluid had gone back to where it was before, way below the minimum line and some fluid at the bottom of my ACD tank. I filled it up again and wondered "what the hell is going on with my ACD?" well to sum things up, i went through 3.5 quarts of ATF because i daily drive my Evo. I went to the dealership and the person who helped me out didnt know jack about the ACD and told me the best thing to do is bring it in. Now, idk if i have to bleed the system and put new ATF or what not, but i know that i have no warrenty due to the mods (especially my cams), and i dont know if the repair will be exspensive. Any suggestions, advices? Anything will do right now....im just fed up with that stupid ACD device right... sometimes i think of just trading in my car for a 9 MR (WHICH I WILL NOT DUE CAUSE I SPENT TOO MUCH MONEY,TIME, AND EFFORT INTO MY 8).

 

What's wrong with bringing it in? You gotta pay to play, right?

 

ya your right. but im just hoping i dont have to pay a big price. Any estimates anyone?

 

all that fluid must be going somewhere... did you check for leaks?

 

dude bring it in it will be covered under warranty, your cams and/ or any mods that are not related to your acd wont void your ACD warranty, it doesn t cost u anything for u to go there and get it checked out, they will tell u what s wrong, then tell u if it will be covred by the warranty which it should.
I had my 3 lights on because my ABS G-sensor failed on my evo 8 05, go it replaced under warranty and my car was making 330whp at the time, and the dealer knew i was going to the track regularly, they took care of me. So dont be scared just go and get it fixed.
every dealer that sells/services evo's have specialy trained technician(s) to take car of the evo's

 

Your ACD is broken. When all the lights first came on in Dec., that meant there was something wrong with the ACD. But because you kept driving it, you're ACD is know broken.

If you look in the manual, it says if all the ACD light come on, the ACD system needs to be serviced by the dealer or someone with the very expensive factory tool.

 

dang somebody gotta heck this ACD thing and we should be able to service ourselves

 

alright cool ill probably bring it in for a check up on monday... do these problems usually occur for new Evos or its just that "$hit happens."

 

$hit happens that s all, the tech that dealt with my 2005 evo 8 never heard of evo with abs g-sensor failing before, i am probably the only one that ever had this problem, so dont feel bad, just get it checked out. And dont listen to some people here you have no confirmation that " it s broken" ( if it was broken u car wouldn t go anywhere since the acd is part of the transfer case) it s maybe just a minor problem, and even if it s broken the dealer will take care of u. let us know how it goes.

 

if there's an ACD fault, the center diff will function as an open diff. The hydraulic pressure simply applies pressure to the clutch plates causing it to "lock up". Most likely there's a leak in the system, and once the leak is repared it will be fine. there's a big difference between there being an ACD fault, and the center diff being "broken".

 

Not necessarily. If they tell him up front, "Look, your car is modified. If we determine the modifications caused the problem, you will be liable for the diagnostic charges", then he could be stuck paying for the diagnosis. That said, it sounds like a leak of some sort, so I don't see why it shouldn't be under warranty.

Being a dealer technician myself (albeit not Mitsubishi), I hardly believe this is true. Even if the technician(s) have completed required training modules on the Evo, there's no guarantee that they actually know what they are doing.

 

well i dont know what kind of dealers u guys have, but here daytona mitsubishi is one of the best dealer i ever dealt with andmany people around here will tell u the same, i know pesonaly the "EVO tech", and i know some other tech from a dealer in Sarasota, and both had to go thru a special training to be able to service evo's, they are the only ones allowed to work on evo when they are brought in for service... and any dealer that charge for diagnostic is full of crap, i would never take my car to that kind of dealer, i have had 3 cars before my current evo 9 mr ( 98 transam, 2001 integra type r, 2005 evo 8) , all were modified and everytime i had a problem with them even if it was due to the modifications, i never had to pay for diagnostic charges. I only had to pay for the repair if the dealer proved the aftermarket part was the cause of the problem.

 

I'm happy for you that you have a mod friendly dealer with skilled technicians. I was just saying that not all dealers are like this.

Well, that is your decision, however, it is hardly unfair to charge a customer for diagnosis in a situation where an aftermarket part caused a failure. It isn't the dealer's fault and it isn't the vehicle manufacturer's fault.

You didn't pay for the diagnosis up front, but if you elected to have the dealer repair the problem, I'll bet that you paid for the diagnosis in the repair charge.

 

yes whenever a repair had to be done because of the aftermarket part i am sure they charged me for the diagnostic under labor which is fine by me, i just dont like dealers that will charge diagnostic fee when the part will be repaired under warranty.

 

i have to put in my 2 cents on this......how can someone not think its is fair for dealer to charge diagnosis fees up front?
if car is under warranty, and mods did not cause failure...you do not pay anyway,
but if mods caused failure, and it is not warranty, and you take car somewhere else for repairs, then then tech just looked at you car for free!!
do you work for free? probably not...
keep in mind i am a mod friendly tech and will over look somethings, but the factory is getting worse about this
