Jerky Takeoff from standstill dq250
« on: November 20, 2019, 11:42:21 PM »
Hello I'm getting a issue in which I have a jerky takeoff especially when hot in both reverse and drive no fault codes are stored in the ecu I have done the basic setting a couple times to no avail flywheel is good with 2 or 3 teeth freeplay gearbox level is correct and fluid is clean the car drives good with no slips or bangs its just the jerky takeoff from standstill is this the warning sign of a worn mechatronic unit? this is very disheartening as driving in traffic can be considered a mare!

In my experience of this it proved to be the mechatronics unit. Quite a common problem as far as I’m aware. Displayed all the same symptoms as above, got the box reconditioned now smooth as anything. Would recommend taking it to a specialist who deals with these units especially.

Hello sorry for the late reply but i do all the work myself and i only have enough cash to change one item either the clutch or the mech the car drives smooth no slipping or anything between gear changes and no fault codes the idle just dips then lurches forward on takeoff from a standstill did yours do this as well?

i had a friend who's did something similar but would also chuck it out of gear completely in first and reverse. it had a code stored and 90% sure it needed a new clutch pack, if it was my car it would have been changed but he didn't change it in the end and sold the car (yeah one of those people) It's hard diagnosing something that can be one or two things, in your case not having any leads.. i would take it to a pro and get them to confirm what it is.

Yes mine had exactly the same symptoms as you’ve described, would lurch forward on take off and was especially bad in reverse, whenever I applied the accelerator pedal the car would kangaroo backwards, this only happened when it was warmed up. Displayed no fault codes and the box was otherwise perfect. Again though I would recommend getting a specialist opinion.
