Weird issue with type-r DCCD (maybe)

[TomsV]

Hey,
yesterday did some donuts and drifting on wet tarmac and sadly got a new problem. I will inspect it closer only next week, but maybe someone can help me or knows the cause.

So driving straight road with DCCD free - all fine, first orange - still fine, but when I put the last orange before lock or lock position, car starts to twitch (periodically), it feels like somewhere in front or middle of drivetrain it periodically stucks or blocks something.

Maybe it comes from axels or other place? It happens only when dccd is almost full lock.

Any ideas what could cause it? All other stuff works very well, no problem with dccd lights.

Regards,
Tom

Could be something to do with the wire or coil (loose plug or broken wire). Being electromagnetic it sounds like the problems start as more current is pulled

Hmm, not so sure, but will check that! I just think if it would be a wire, than it should do errors in any lock position. And before donuts, everything was fine.. Interesting that the issue is showing up on straight driving where every wheel is spinning the same speed..

Does it happen in every gear or just one? Sounds like an electronic fault rather than mechanical to me.

Yes, every gear. Also in neutral postion.

maybe check all the plugs and sensors are still connected properly. Does it idle ok?

Yes, everythings works fine, no other issues until I turn the dccd lock above half.

Thats what makes me think poor connection/corroded/weak wire. Seems to be a common fault the dccd coil wire, my one needs soldered. Sounds like the coil is ok with some current going through it but not the full amount. However doing doughnuts and drifting could have easily just loostened a connector/plug due to gearbox vibration. You could check the resistance with a multimeter but you need to know what it should be

Allright, thanks for the info! Will find info about the resistance! I did rebuild my gearbox this winter, all connections should be fine, but will check them! Hope to get more opinions here..
