Hi all, Since 2 weeks I'm the proud owner of a 10 yo Octavia. She's got 182000km on the clock and I got 2 months of warranty from the 2nd hand car dealership I bought it from. So far I've driven 700km and gotten a number of errors and warnings, of which I believe the misfires to be the most serious. I'm trying to understand what could be the issue with the car so I can better understand when a dealership is just trying to dodge having to pay, or when they might have a point. I've gotten een OBDeleven to read out the fault codes. I'll start with the easy one of which I'm semi-sure that it's not related to the other codes. 3 times in those 700kms I have gotten the dutch error: "Storing: werkplaats! Wagen alleen in positie P verlaten", which in English would be "Error workshop only leave vehicle in P position". The ODBeleven found a non active error code B116229, as I currently believe it's a common broken microswitch in the DSG stick that can be replaced. Am I correct in thinking that there's no real risk in letting this be for now, other than that the errors are annoying? Then there is the Start Stop System. At the start of my drives the car indicates that the start stop system has an error. I find no error codes related to it, but I do think the battery voltage is a bit low with 13,9V when charging and 12,2V with the engine off 3 min later. There's some aircon energy management faults that also point towards the battery being on its way out. I'm mainly including this because it could somehow be related to the misfires in a way I don't understand. Then for our main event the thing that actually worries me, the misfires. I had the car in my possession for 400km without this happening before, when after 20 minutes the engine suddenly started running very poorly. At the time I was doing 35 km/h in 4th gear. I pulled over and turned the engine off. When I restarted the issue was completely gone. I've driven 300km since without the issue reoccuring. Misfires were recorded in all cylinders. There's an active fault for 'Diagnotistic interface for data bus', U100800, that I can't find any info on. There is also an active fault saying there's no communication with the generator that could or could not be related. I called the dealership, and they said that since the errors don't stay active on the dashboard of the car, they would like me to keep driving to see if anything sticks before going through the trouble of diagnosing. I'm trying to figure out if that is a reasonable call or not. Could the misfires just be a one-off that don't mean anything more serious? Sorry for the overload of information and thanks for bearing with me! Sidenote: The misfires happened before I installed a newer OEM multimedia screen and some software updates.
