glad to hear everything worked out for you

 

another thing to do, as i had all three go nuts on me, is check your wiring, ie: clearances on the fender wells, i nearly rubbed through both sides after a suspension change. (only really wore through one)

 

I will keep that in mind for the next one

Hi everbody, I live in Switzerland, Europe.
We are 3 friends, Evo VII owners (and lovers), to have the same problem : when it's hot outside (30°C, 86°F), the 3 lights come on...
MUT II says "pump failure".
I made some tries, in fact the max pressure is down to 11-12 bar, and should be at 16 or more.
After some researchs, here is what I've found :

Here in Switzerland the pump is sold at 4'500 CHF, about 3600$, 2000 GBP, 3000 Euros...
I've foud a new one at www.japancars.com, exactly half the price, all included (port, insurance, customs, ...) !!!

Jeller, how much did your pump cost, do you know it ?
Other people, do you know the price of the pump ?

of Switzerland :

 

I did the job and now it's OK.

At this time 3 other friends had the same problem, each time the pump was k.o.

So, already 4 pumps bought by japanparts... any other source ???

 

i have a full acd unit for sale geezzz 3,600$ for acd thats crazy bro!!

 

Is that a crack on that housing from the pic?

 

yes, lots of cracks all around...

 

UPDATE:

First pump was replaced by the dealer last year. After alot of argument with what is wrong, they finally replaced the pump after all. Warranty billing shows $1800 with labor. Everything was fine, till this am.


UPDATE AGAIN:

ALL 3 lights on agian, 1 year later and the pump is doing it again. Back to the dealer I go..... I will update when I get some answers.

Any Idea why this happens everytime I do a track day?

maybe it's overheating? especially at the track. Make sure mits. doesn't find out that you go there. Good luck.

 

It could be interesting to check the ACD oil temperature when you are on a track...

Now I'm scary to go back to track

For you question, why it does happen when you're on a track, perhaps it's the outer temperature... When it's cold, the oil is more fluid, the pressure is harder to reach...

Who knows...

for earlier evos ie 7s and 8s.. this is your problem..

9s .. sorry no clue as these gets worn over time.. unless you're a 1/4mile freak at every traffic light

 

Maybe they are putting in the wrong fluid?

 

honestly i feel no pity for you.... you hit the track and you overheat the ACD somehow.... i dont know maybe you run different sized tires/wheels? maybe u set it not as tarmac but gravel/snow and beat the **** out of it? i dont know for sure but then u RETURN to the track. now u got it again? good for you, hope you sell your evo lol

 

Yeah, its just wierd how about 2-3 days after a track day it happens.
and there is 5 other evos out there without ever having an issue and drive wayyy more.

pumps only a year old, I could see if it was much older.
