Jump start 2004 vw touareg battery - 2004 Volkswagen Touareg

SOURCE: 2004 VW Touareg won't start

I had/have the exact same problem with my 2004 Treg. I took it to the dealer in April and they told me it was the fuel pump and replace them. Everything was fine until the other day when it happened again. I took it to a local mechanic who told me it was the crankshaft sensor. If it happens again I'm selling the car for scrap!

It all depends on several variables.

• Were the connections clean? (battery cables and posts
• Did you have a good connection with the jumper cables? (some battery posts are hard to get at and clamping a jumper cable can be difficult)
• How long were the jumper cables left on? (weaker batteries will require leaving the jumpers on for a longer period of time (15-30 minutes)
• Was the other car running? (jumping battery to battery will have the same effect as jumping alternator to battery)
• Was the car with the dead battery warm or cold? (if the car you're trying to start was hot, it may not be the battery that's at fault

If the car you're trying to start is cold, ensure your battery connections are clean (manually cleaning is better but there are some very good sprays that work pretty well.  Leave the jumpers on for a longer period of time with the other car running.
I hope this solves your problem.  Best of luck.
