ESP light came on at 70mph
2002 e430 Just cruising today at 70mph and for one-two seconds the power cut out and the ESP light lit up out of nowhere. Seems odd, but I am wondering if that is a symptom of some part that may be failing?
Thanks

Well - frankly a generic scanner most likely will show up nothing - but always good to check.
I would recommend you check tire pressures - and tire condition - all around as 1st step - a couple of lbs differential from the opposing side tire can cause ESP to trigger - plus your E430 runs lower profile tires to begin with which accentuates pressure/condition differential

No codes to report...using cheap-o scanner. I did inflate 2 tires, they were a few pounds off, likely due to the cold weather. When I said the "power cut off," I mean I was going 70mph with cruise control set, and the car suddenly slowed down and the ESP light lit up. It felt as if it was suddenly completely out of gas, or the ignition was turned off....but it only lasted a second or so and has not done it since. It was one of those oh sh@t moments when you are wondering why all of a sudden your car isn't running.
On a side note, and likely not related, a few days later my idler pulley froze up and ate the belt. I thought I had been hearing odd noises from the belt/pulleys/water pump...something up front. Replaced both idler pulley, the belt tensioner and drive belt. Much quieter now.

Likely a failing wheel speed sensor, it sent a false reading and the car tried to react to a wheel slip event that wasn't actually happening. Dealer level scan or wait unitl it gets worse.
