Services Performed
- Scanned system for codes and found several stored. PO301 – Cylinder #1 misfire condition, Other 4 codes were for communication and voltage issues. We noted the battery is new but very swollen on the sides. Checked charging system and found normal voltage. Removed battery and customer went and brought us a new one. Could have caused the voltage and communication codes. Moved spark plugs and coils around as the first test but misfire would not present itself. Monitored scan data and found fuel trim readings running lean. Determined that the valve cover PCV runner was leaking. The way it is could cause the lean condition and possibly the misfire. Informed customer about the finding and replaced the valve cover and PCV valve with OEM parts. Cleared system of codes and test drove. Fuel trim readings were normal. Started after different times of sitting and seemed good. Started on Saturday morning and slight misfire was felt. Cylinder #1 came back as the code. We then performed a block test of cooling system and this passed 2 times even though we could smell possible coolant in exhaust when first starting. Research shows these turbo motors can be prone to head gasket issues. This would require taking to the dealer for repair unfortunately.
