Hello guys, im new here! =)

i recently had my engine rebuilt and a new ECU installed ( MAXX Ecu )

After this was done the 4WD light would come on now and then.

Now it´s down to, only working when the car & system is cold, then it works for hours, tried driving it around for 2 hours, w/o any light cooming on and the system fully working.

if i turn the car off and on after a while the 4WD and ABS lights up right away and the car is in RWD mode.

I had it taken to a professional mechanic, he could fine NO errors with it what so ever, which is anoying as ****, as i had a tune scheduled for it this friday.

The system was bled, at rebuild, and all the fuilds are changed.

Any1 know what could cause this anoying as **** error?

Best regards

Does the lights come on when you start the car or while driving?

No, it only comes on when i start the car when it´s warm.

if i drive the car when it´s cold all systems work flawelessly untill i restart the car and then the issue comes up and does not power the front wheels at all.

If you turn it off without the fault code and restart it after a few seconds does it come on or only after it's been standing a couple of minutes?
Vspec or regular?

Regular, have to try that tomoz murning, when its cold again,ill get back on that, i Did not get The attesa box to show me any fault codes... Anoying

Works like a charm when i restart The car a few Times when its cold.

Update, and whats been done so far.

When i start my car ( when it´s cold ) ie havent driven it any, everything works perfectly with it, untill i restart it ( when the engine is warm ) then the ABS and 4WD light comes up and the systems are off.

Things i have checked are ALL electrican sensors, and wires ( a professional car electrician company ) the TPS is adjusted to closed 0.45 & the attesa oil system is bleed.

This issue occured after the engine being rebuilt last fall & a new ecu was installed ( MAXXecu ) engine & car runs perfect when it´s started cold, but when restarted the 4wd light and abs lights up.

Attesa box not showing any fail codes but 6 short and fast flashes, but there are no faults with the abs front sensors or circuit.

Really hope you guys can help me out !
