What P247A means
P247A is the out-of-range verdict for the third bank 1 probe, which sits further down the aftertreatment line. It is the best documented code of this series. Volkswagen's 2014 quick-reference books for the 2.0L TDI CJAA (Golf, Beetle) compare the control deviation with an engine-speed and torque map, while the 3.0L TDI in the 2014 Touareg flags a gap between target and measured temperature above 200 K or below -100 K. Ford's 2015 diesel summary includes it with the high-side limit of about 1150 °C. A reading too high here often follows an uncontrolled soot burn in the filter, one too low a regeneration that never got hot enough.
P247A at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor0.5 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P247A
- MIL on
- Filter regeneration aborted or repeated
- Emergency mode with reduced power possible
Common causes of P247A
- Most likelyOverloaded particulate filter burning off too fast
- PossibleRegeneration not reaching target temperature (VW low-side check)
- PossibleProbe aged and misreporting
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P247A means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 4 | Area: auxiliary emission controls (catalytic converter, EGR, EVAP). |
| 7A | The exact fault in that area. |
What to do next
- Note P247A and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P247A
What does P247A mean?
P247A means "Exhaust Gas Temperature Out of Range (Bank 1 Sensor 3)". P247A is the out-of-range verdict for the third bank 1 probe, which sits further down the aftertreatment line. It is a generic code, so it means the same on every make.
Is it safe to drive with P247A?
Drive gently and only to a workshop. With P247A the car can go into limp mode (reduced power) to protect itself.
Will P247A fail an emissions test?
Yes, it can. P247A is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P247A to fix?
Difficulty: hard. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P247A clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
