My 02 Boxster S was giving a flashing oil level indicator on startup with no oil level indicated. After a few seconds flashing stops and display goes to time. At recent service I asked mechanic to replace oil level sensor. Cost was about 50 pounds for part plus three hours labour. However having replaced the senser the flashing indicator still showing. Local Porsche dealer had car with same fault showing after sensor replaced. They plan to replace digital display, but cost of part approx 1200 pounds about $1500. The mechanic I was dealing with suggested taking car to digital display tech. I wanted to check if anyone has had same problem. Also has anyone dealt with digital speedo companies? Not sure how they can help!
