Frozen Scooby
 

Any ideas? Been sitting out heavy frost last night and tonight.never defrosted during day. wouldn't start this pm.happened christmas morning last year after heavy frost.battery fine (changed it after last year after that episode and starter turing ok. nearly caught once or twice) just unusual that it's only happened when well frozen. Car is regularly serviced with only minor mods,(MY00) full decat, k&n, boost controller.
