Hi, hoping someone has some experience of my issue. I have a 2015 Civic diesel. Runs like a dream. Sent it for service, came back fine. Drove it several times that day with no problems. The next morning Check System warning. Back to mechanic, fault code p2199 (relates to correlation issue between two sensors). Anyway he cleared fault and I drove the car several times that day with no issue. Next day same issue. Cleared fault ,drove car several times, nothing wrong. At 1 min past midnight I started the engine and fault re appeared. Have changed the two sensors that cause the fault, cleared the fault and everything is fine until midnight. Anybody know what's going on. Is it simply remembering the fault from previous day. Any experience with this would be greatly appreciated.
