Here is the web page with the motronic fault code information that tells
you how to determine if you coils are the problem. The cost was coils
run about 80.00 each. It is very easy to replace them. In fact its
easier than replacing the spark plugs. You have to remove the ignition
coils to get to the plugs.
Hopes this helps. BTW, I only needed one coil. Some have had to replace
all six.
Good luck and let me know what you determine.
