We are a multi-TDI family, sold our '02 GOLF TDI to our son. He was gone working for four months, over this past harsh winter. His car was literally deep in snow for a few months and the battery was dead when we went to start it up. I'll read more of the posts and the VAG-COM info, but are we really stuck with going to the dealer to get this re-set? I find that difficult to accept! Thanks for offering any assistance. Just specific links to existing info would be great for now, I'll read a bunch more. Thanks for being there!
