Hey I'm new to the forum I've purchased a wrecked 98 tdi jetta from a co-worker he hit culvert. I got the front end fixed. Recently we've had some cold days and the battery was dead when i went out a couple days ago. so I jump started the car and now the red temp light and oil light are flashing. I was curious if I messed up the sensors when I jump started the car. Any help is appreciated. Thanks in advance.
