Traction Control causing loss off power, any help? CLA220D

[Tfak1992]

Hi

I own a 2013 CLA220D, Recently I've had issues where when they traction control lights comes on when a wheel spins and causes loss of power, the power never comes back and revs to around 3000 (Reduced power mode). I have to pull over, turn the car off and on again to which the car then runs find again until a wheel spins. I turned the Traction control off and the car is fine, when a wheel spins the power stays. What could be the biggest culprit for the issue? The car has been plugged in but is returning no faults.

It's been difficult to drive over the last few months with the cold weather/ice as the wheels spin easily.

Any help will be much appreciated

Firstly, just to say that in 15 years of Mercedes ownership, I've only seen the ESP light come in very rarely... probably no more that 3 or 4 times in total, in extreme conditions.

I am not berating your driving just thinking out loud whether there was always something wrong with the ESP system on your car? Of course, if you like a bit of spirited driving in the rain, then that's fine.

Then, the fault codes need to be read by MB STAR. Where did you get these read?

Hi

Thanks for replying, it was icy a few weeks ago, having to put my foot down a little to pull out onto busy main A roads caused the wheels to spin slightly causing this issue, also driving down muddy lanes/roads (I'm no driver who thrashes the car about I'm older enough to be past that stage)

The car recently had a new wheel bearing fitted and ever since then it's had this problem, potentially this could be causing the issue? I'll take back to the garage to be checked but was curios to see if this has happened to anyone else or would anyone have any other ideas what it could be.

The car was returning no fault codes that's why it's confusing as can't pinpoint it to a code to read into.

Thanks

When replacing the wheel bearing, they may have somehow disturbed the wheel speed sensor or its wiring. Do you know if the garage used a genuine MB STAR scanner?
