Hello all. I finally got my ride out in the sun this weekend. We had an autocross event at a local shopping mall this sunday.

Heres a nice pic of me on the run:

Even more photos ....

And here's an onboard video, wich leads me to my PDAS question. At 30 sec theres a beeper going off, and the red 4WD light to the right of the big ! goes off as well (not visible in the video I guess). It happened twice in the same corner. I can't say it affected the ride in any way, so I think the "error" must have been intermittent. What do you think ? Bleed the locks and hope it solves it ?

Can you verify that your brake fluid reservoir is at the upper limit? Its been my experience that you can get those lights if you don't, especially when driving aggressively.

Jan-Terje

Yes I did check the brake fluid level, that was my first thought also, It's at the top marker.

Next step I would take would be to bleed the entire system. Including the Bomb (pressure accumulator), valve block, both lateral and transverse locks as well as all of the brakes and the clutch slave cylinder.

It also might be interesting to run a few timing cycles on the pressure pump.

Jan-Terje

By "run a few timing cycles" you mean; how long does it run on startup ?

dfinnegan

Yes. And, hit the brakes several times with the engine running and you are standing still. Until the pump kicks in. Then time it.

One problem that occurs is that the bomb, which has an internal bladder to accumulate the pressure charge, gets tired and won't hold the appropriate pressure.

Sometimes it's just a full bleed that's required. If you change the color of your brake fluid it's a little easier to determine where the old and new fluid change occurs.

There's more info in the Shop Manuals. If you need more data PM me.

Jan, the PDAS warning problem is sometime indipendent from bleeding and fluid brake level.
When the alarm goes on, you lost the PDAS effect.
To solve your problem, if level & bleeding, accelerometers and coils are ok, you need to get a look at this thread

Thanks to garret376

Ciao Paolo

BTW: any news about regearing?

FYI, I had the same experience and it could mean that data from a wheel sensor is not being received. Mine turned out to be loose ground wire from the rear little "barrel" and the swingarm?

Jan-Terje

Thank you for your hints and tips !

I did some timing runs on the brake booster pump. First run was 12 seconds. After that it ran for approximately 6 seconds after pushing the brake pedal twice. It ran consistently 6 seconds every time. It seems reasonable right ?

@Paolo: I did send that guy an email but never got a reply. I have not had the time to follow up on him either. But, as I told you GuardTransmission did offer a complete gear set, not ring and pinion though. Thank you for reminding me of that thread by garret376 !!
