Autodata Company runs Autodocta guide, where solutions to common, but difficult to diagnose, automotive problems are presented. Today we present a problem for a Subaru Forester with a 2.0 engine from 2013.

We have a problem with a Subaru Forester 2.0 from 2013, where the engine oil pressure warning light is on, despite the correct oil level. No fault codes were recorded. Please help us.

Answer: This fault relates to several Subaru models with FB engine code. It is caused by a badly designed protective cover of the oil pressure warning lamp switch, which causes water leakage followed by a short circuit. Check the oil pressure warning light switch. Replace it if necessary. Thoroughly clean the cable bundle plug of the oil pressure warning light switch. Install a new version of the oil pressure warning light switch cover, available in the Subaru parts section, Fig. 1.1. This should fix the problem.
