The vehicle listed above has a TSI engine with 119,665 Km. the vehicle had the codes above. The spark plug was change, coil, injectors, PCV valve, intake manifold, oxygen sensors, catalytic converter, carbon clean the problem still persist.
Compression test was done, low compression was found in cylinder 3 and 4
The engine was rebuild and the problem still persist.
Anyone had a similar problem I really need some help here,the technician who work on it work at the dealer and don’t know what next to do, so my options are limited.

Couple things first. Can you check the codes that you have because they are not correct?

P0304 - Cylinder 4 misfire
P2188 - System too rich
I assume this one is P013A - HO2s circuit slow to respond rich to lean
01259 - Is not a valid code

Have you confirmed the compression is correct on cylinder 4 after the engine was rebuilt? Also, it is hard to tell in the video but is the smoke dark in color or black?

P0304 – Cylinder 4 misfire
P2188 – System too rich at idle bank 1
P2178 – system too rich at idle bank 1
01259 – Fuel pump Relay fault no longer present
P130A = Hide cylinder

The mechanic still has the car so I don’t know if the low compression was corrected after the rebuild. Will try to contact him later.There was grey smoke coming from the exhaust.

Okay, grey/black exhaust is excessive fuel so that would tell us that the codes for too rich points to a mechanical issue and most likely not a wiring issue with the control module or sensor. Let us know about the compression when you find out and we can hopefully figure this out. Thanks

Spoke to the mechanic yesterday he said good compression in all 4 cylinders when he replaces the camshaft sensor the vehicle stop misfire. The code was cleared and the vehicle runs properly when he took it for a test drive. Note: when the scan was done there was no code indicating a camshaft sensor fault. Hope this is an end to my problem.
Thanks for your assistance it was greatly appreciated.

That is great. With that info, it most likely just set when the sensor was unplugged. However, if it is not active then you are most likely good to go.

Clearly we don't need to worry about it until there is something to worry about. Thanks for using 2CarPros.
