Ok I have 11 e92 335i rwd. Car has 35k on it. Tires were bald so I just replaced the oem tires last night with a set of snow tires. Same exact size tires. I was driving the car today and when I get on it the tracking control was coming on... I was on dry pavement. If I turned the traction control off and got on it its fine. Any idea why this is happening? Is it just a coincidence that it happened right when I put new tires on?

Most traction control problems that occur are related to the loss of a signal from a wheel speed sensor, a pump that fails to run, or a high pressure accumulator that leaks or can’t hold pressure.

Wheel speed sensors can be checked by measuring their resistance with an ohmmeter and comparing the reading to specifications. Sensors are magnetic and may not produce a good signal if the tip is contaminated with metallic debris or the air gap between the sensor tip and tone ring is too large.

If a code indicates the high pressure pump isn’t working, the underlying cause may be a faulty pump relay or a bad wiring connection. If the pump fails to run when the relay is bypassed with a fused jumper wire, the pump has failed and needs to be replaced.

A code that indicates the system is not holding pressure usually means the high pressure accumulator is leaking (check the seal between the accumulator and modulator/pump assembly, or that the rubber diaphragm inside has ruptured allowing the accumulator to lose its nitrogen gas charge (replace the accumulator after depressurizng the system).

Problems may also occur with any of the solenoid valves in the TCS/ABS modulator assembly. The problem may be mechanical (failure due to rust or corrosion in the valve) or electrical (failure of the solenoid). On most systems, the valves cannot be replaced separately so the entire modulator must be replaced as a unit.

If a code indicates an internal module fault, the TCS/ABS module can usually be replaced as a separate item. It may be attached to the modulator assembly or located elsewhere in the vehicle.

Communication errors between the TCS/ABS module and PCM or BCM (Body Control Module) may be the result of a wiring fault.

Did you just install Continental winters? If they are continental winter non run flats they my be your problem. They are too soft for our dsc/dtc traction control.

Is that only for that specific tire? I have Nokian Hakkapeliitta R2 no issues... yet.

Soft tires + aggressive traction control invocation = what else were you expecting to happen?

Yes, obviously if you turn traction control off it will no longer alert you to loss of traction; perceptible or otherwise.

What are the F/R tire sizes? Are all 4 brand new?

I had the issue with Conti Winter Contact

New tyres always take a couple of hundred miles to bed in...
