I've recently come across a problem with my 2014 Audi 184ps. As I'm driving along, the car will sometimes hesitate/jerk. Putting the gearbox into manual mode doesn't help.
What's worse is that sometimes, when I'm parked up, the rev counter will start to behave erratically and drop revs, eventually stalling the car (an automatic!!) lol.
I have done a fault code scan and it has shown the following errors related to the engine.
It seems that the pressure sensor in Cylinder 3 is having an issue, but I replaced all 4 glow plugs and the error is still there. I can't verify that the replacement glow plugs were completely brand-new as i bought them off eBay. They were advertised as new and did look kinda new but admittedly I can't verify this.
Has anyone seen similar issues before? Is it more likely that I received a bad set of replacement glow plugs or could it be something more serious like a wiring issue?
