Have Volvo Questions? Ask a Volvo Mechanic for Answers ASAP
My name is ***** ***** I am a Volvo dealership technician. I am going to try to help with your question today. What code are you getting?
Okay, this will need to be taken to a Volvo dealership. This could simply be a software issue. They had problems with the ECM software incorrectly identifying a leak.
Once the correct ECM software is installed or verified, a leak test can be run with the dealer computer. If there is a leak, the evaporative emissions system will need to be smoke tested for leaks. I will say that I would recommend against a non-Volvo fuel cap. I have seen them leak or not vent correctly.
An incorrect leak detection pump can also be problematic.
