What's the best place to get a front PDC sensor these days?

[TowX]

Left front is dead. That's the 7th one to go bad, just one more and I'll have replaced them all over the past 2 years. I've only replaced one sensor on my 528 in 13 years, how does that happen?

Anyway, dealer wants $179 for the sensor which is crazy inflated. I get all my Porsche and BMW parts from Pelican when I can, great customer service, but they don't carry these sensors. Said they fail too often and it becomes a parts warranty nightmare. So who's the best source currently?

And has anyone figured out how to change the front outboard sensor without yanking the front end off? It's still too cold outside to do that.

Thanks.

I just replaced my outside front sensor and there is no other way to replace them except to take the front bumper off. As you can see in the picture, they are hidden and the connector is on a L-shape. This is my first sensor going bad, but I am still having problem. All the sensors are working, but I am still getting the beep and flashing light.
