I'm hoping I can get a little help with weird issue that I've just started experiencing with these warning lights coming on intermittently on my 2009 jetta sportswagon (141K). They only flash for a brief second and one audible chime is heard but nothing happens with performance of car. I did just have a battery replaced and it started occurring after that (car died while on vacation, AAA replaced battery). I have also just recently had the RCV valve replaced in the AC compressor and AC is working great now.
As for a little more history on this car: Timing belt\water pump maintenance done at around 90K I think and transmission replaced at 113K. The CEL light has been on for a few months and local VW mechanic is showing an exhaust pressure sensor code. The car wasn't going into regen mode but he's able to put the car in that mode for me and I drive it until the pressure numbers are exceptable. That issue seems to have corrected itself though and last two times at shop they were able to see that my car had gone into regeneration on it's own and the last time it showed that the exhaust pressure way down so that's good (CEL is still on though)
Back to engine fault workshop and glowplug light, I can sometimes make it happen if cruising along at highway speed in 7th gear I think. What i'll do is let off gas until speed drops around 58 mph and rpm at 1800 and the car has down shifted, at that point if I give it just a little gas and it upshifts and then those warning lights while show for just a split second. Car doesn't sputter one bit though. This isn't the only time that this happens but it does seem to occur around 1800 rpm. It's also not occurring overly frequently and car is running great. Almost seems like an electrical issue somewhere? Does anyone have any ideas what could cause this?
I apologize if I didn't do this the correct way, I did tried replying to another post on this discussion to get some help but hadn't heard anything back so thought I was create a new post.
