Fellow Volvo owners:

After a lot of frustration, I have begun compiling a list of simple causes for the Check Engine Light coming on.

Here goes: Please reply with additions from your experience!

1. Gas cap not clicked shut
2. Lube oil approx 1 quart below full line.

Many thanks.

Rather than a list which could go on for pages and pages, why not just do like others do? Go to a friendly autoparts store and have them read and clear the code? Actually, everytime you bring the oil back to pour in their tank, after an oil change, it is good practice to read and clear the codes. That gives you a head start on potential problem areas.

BTW, one quart low should not turn on the CEL.

Please answer, we need to know if the advice is good or bad. The 164 has a new home, all I am left with are 2 turbos :)
