Selespeed/clutch knocks when standing 1-st gear (156)
It's me and my '00 156 SW 2.0 TS Sele from cold Moscow.
Apart from Putin elections we had here, there's another hell going on.
Since I bought the car (2,5 yrs), she would do a strange knocking/tapping/clunking when standing still with the 1st gear engaged. Thus, it occurs at traffic lights, but not every time. Yet I hadn't find any regularity, it can just behave itself this way on any given stop at any given moment.
The clank itself is rather heavy and repetitive at a rate of 2-3 per second. The sound is like a gear wanting to be engaged, and the car shakes a bit, but if I depress the brake, it won't tend to move forward. Even more, if I push the gas a bit to move the car a few inches, it moves forward smoothly as usual without any jumping, and after disengaging the clutch again, this sound goes away.
If I swith sele to N, sound disappears too.
What the hell could it be? I already repaired sele, replaced the clutch solenoid, recalibrated, repaired and calibrated the push rod etc. I used FiatECUScan to monitor faults and sele fluid pressure, and nothing is out of the margin. I suspect thus that the fault lies within clutch or 1st gear mechanically, but then why the heck it's not regular...
