Hello everyone, I have a small question and I hope someone can help me. So brace yourselves, I have quite a story below I have a 2016 T6 4motion 2.0 TDI with a CXFA 150hp engine and 50,000 km mileage. History:
P010100 - Mass or Volume Air Flow Sensor "A" Circuit Range/Performance
Intermittent
P24D000 - Particulate Matter Sensor Supply Voltage Circuit Low
Intermittent
P046C00 - EGR Sensor "A" Circuit Range/Performance
Intermittent
P040200 - Exhaust Gas Recirc.Flow Excessive Detected
static
P066A00 - Cylinder 1 Glow Plug Control Circuit Low
Intermittent
P066E00 - Cylinder 3 Glow Plug Control Circuit Low
Intermittent
P019100 - Fuel Rail Pressure Sensor "A" Circuit Range/Performance
Intermittent
P056200 - System Voltage Low Voltage
Intermittent
P064100 - Sensor Reference Voltage "A" Circuit Open
Intermittent
P065100 - Sensor Reference Voltage "B" Circuit Open
Intermittent
P069700 - Sensor Reference Voltage "C" Circuit Open
Intermittent
P06A300 - Sensor Reference Voltage "D" Circuit/Open
Intermittent
I reset it, and did another diagnostic a few weeks later without having driven, and the codes are almost completely different:
P226D00 - Particle filter damaged or substrate missing Intermittently
P24B100 - Particle sensor measurement electrode short-circuit to positive pole Intermittently
P24B000 - Particle sensor measurement electrode short-circuit to ground Intermittently
P046C00 - Exhaust gas recirculation transmitter 1 implausible signal Intermittently
P040200 - Exhaust gas recirculation system excessive flow Static
P029900 - Boost pressure regulation limit not reached Intermittently
I note that the codes P046C and P0402 related to EGR and exhaust are the only ones that repeat.
In conclusion, I think it's a problem with cables that have been gnawed or oxidized connectors, but I don't see anything under the hood (I didn't go under the car and I didn't disassemble anything).
My questions are as follows:
- A cable gnawed by a marten, hence a repair and installation of a marten deterrent system.
- From time to time, the glow plug light turns on while driving but it's very rare.
- Sometimes (every other time) there's a loss of power during the first 30 seconds (can't start uphill without aggressively accelerating, etc.)
- I have a sense of consuming more fuel and having generally less power, but it's not too obvious.
- Sometimes there's strong ventilation under the hood when the car is stopped and shut off, and sometimes not (regardless of engine temperature).
- Occasionally, the glow plug light starts flashing after taking the highway with a strong power limitation around 100 km/h.
- The engine light is constantly orange.

My questions are as follows:
- Do you have any idea where this could be coming from?
- What are the components I should check?
