Here is another example you could try, all in bash shell without external utilities or subshells except for the mv command, so it should be reasonably quick.

Code:
#!/bin/bash
oldIFS=$IFS
while IFS="," read -a car; do
  if [[ ${car[1]} != VIN ]]; then
    for file in *"${car[2]}_"*.jpg
    do
      if [ -f "$file" ]; then
        tofile=${car[1]}${file#*"${car[2]}"}
        echo mv -- "$file" "$tofile" 
        car[${#car[@]}]=$tofile
      fi
    done
  fi
  IFS=","
  printf "%s\n" "${car[*]}"
  IFS=$oldIFS
done < test.csv

It also does not entirely produce the proper output format:
Code:
mv -- 002795_001.jpg WDD1173461N6437866_001.jpg

, but it should give you some idea..

Remove the echo statement when it does what you want...

NOMBRE

       qwordtrans/kwordtrans - Multi Language Word Translator

SYNOPSIS


       qwordtrans [--help] [--conf dir] [--nogui] [Qt-options]

       kwordtrans [--help] [--conf dir] [--nogui] [Qt-options] [KDE-options]

COMMAND-LINE OPTIONS

  Wordtrans options:

     --help
	Shows a helping message.

     --conf dir
	Directory with the configuration files. This is used in the web
	interface to read the configuration files from the directory
	/etc/wordtrans, so wordtrans can be executed as the user nobody.

     --nogui
	Behaves like the console application "wordtrans".
	Example: 'qwordtrans --nogui -d i2e car' is the same as
	'wordtrans -d i2e car'

  Qt-options. All Qt programs support the following parameters (from
  qt-doc):

     -style= style
	sets the application GUI style. Possible values are motif,
	windows, and platinum.

     -session= session
	restores the application from an earlier session.

     -display display
	sets the X display (default is $DISPLAY).

     -geometry geometry
	sets the client geometry of the main widget.

     -fn or -font font
	defines the application font.

     -bg or -background color
	sets the default background color and an application palette
	(light and dark shades are calculated).

     -fg or -foreground color
	sets the default foreground color.

     -btn or -button color
	sets the default button color.

     -name name
	sets the application name.

     -title title
	sets the application title (caption).

     -visual TrueColor
	forces the application to use a TrueColor visual on an 8-bit
	display.

     -ncols count
	limits the number of colors allocated in the color cube on a
	8-bit display, if the application is using the
	QApplication::ManyColor color specification. If count is 216
	then a 6x6x6 color cube is used (ie. 6 levels of red, 6 of
	green, and 6 of blue); for other values, a cube approximately
	proportional to a 2x3x1 cube is used.

     -cmap
	causes the application to install a private color map on an
	8-bit display.

  KDE-options:

     --help-qt
	Show Qt specific options.

     --help-kde
