On 2/10/07, I drove about 10-12 miles and shut her down for about 3 hours. The temps were in the minus single digits and I have been plugging it in over night. I came out and it started right up, after the glow plug light came on for 2-3 seconds. I thought it was a little odd after only three hours, but it was COLD. After idling for a few minutes I started down the road and the CEL came on within a 1/2 mile. I drove her home and brought her to the dealership on 2/13. Here is what they found: P0299, "inspect and found MAP sensor full of water-call T.A.C (case #9471085) engeneering is investigating for permanent fix. clean out air intake tubes-clean MAF sensor-could not get all of water from MAP sensor-replace MAP sensor-reflash ecm w/ updated software". They recommend I put the winter cover on as that should/could help and they have found similar problems lately. It has been cold for several weeks. Just letting everyone know. Thanks!
