Hi Scott, we've sold about one hundred of 0-5 bar Oil Pressure Sender 911 606 111 01 / 911 606 111 03 over the last 12 months with only one returned, so it's odd that yours isn't working. Email your order confirmation / purchase details to "sales at uro parts dot com" and we'll get you a prepaid return label (so our engineers can check out that sensor) and ship you a replacement sender.
