I need assistance, please.

Hello, I've been working on fixing my wife's Evogue. I had the EGR valve mapped out and was told I had a MAP sensor issue. After trying a few different parts, I was able to get the correct one installed.
However, I'm still experiencing issues with my cheap iCarsoft scanner.


If it helps, the vehicle is still stating "Map problem" and "Egr valve" periodically.


We had an owners club when I owned my Mk4 Golf, and we used to give them beer tokens—not a lot of money—so that they would assist one other out with issues and other things. No one would take advantage of anyone.
Paying honestly doesn't bother me.


I'm in Shevington, Wigan, and I'm willing to offer "beer tokens" to anyone who can assist me.

Regards in advance

Circuit for P245A EGR Cooler Bypass Control/Open Bank 1

I appreciate any assistance in advance.

I would probably start by purchasing some "MAF sensor cleaner" and cleaning that first. That area seems to be overly susceptible to oil and filth. Knowing that the car can accurately compute its airflow with a clean sensor is just convenient.

The second thing I would do is grab some "Carb/Throttle Cleaner" and lightly mist the intake areas and vacuum pipes. You can tell you have a vacuum leak if the engine switches idle and too much unmetered air is entering.


Purchase some DeOxit as well. A small amount of that spray will restore electrical connectors to their original condition if you begin unclipping them. Electrical gremlins are a major problem at JLR, so whenever possible, take measures.

Lumo AI says, "You have something extra dirty," which I highlighted in red. PS: Google AI is extremely ****, while Lumo AI is fantastic.

1. A dirty or malfunctioning MAP sensor

Why: The MAP‑MAF correlation issue can be caused by a dirty MAP sensor that provides an inaccurate pressure reading.
How to proceed:

Check the sensor visually for oil residue or carbon buildup.
Use a MAP-sensor-safe cleanser to gently clean it if it's dirty (spray the sensor tip, let it dry, then reinstall).
Replace the sensor if it continues to produce out-of-range voltage (verify with a multimeter against service requirements).

2. Issues with MAF sensors

Why: The association with MAP will also be broken by a weak or sporadic MAF signal.
How to proceed:
Examine the MAF connector for any loose pins or rust.
While the engine is revving, measure the sensor's output voltage (usually between ~0.5 V idle and ~4.5 V wide-open).
If the sensor element appears dusty, clean it; however, many technicians would rather replace a suspicious MAF than take the chance of harm.

3. Vacuum and intake air leaks

Why: P006A might be triggered by unmetered air entering the intake manifold, which can cause confusion in the ECU's computations.
How to proceed:
Look for any fractures or loose connections in the intake duct, clamps, and hoses.
While the engine is idling, conduct a smoke test or lightly spritz suspected leak areas with carburettor cleaner; a change in RPM indicates a leak.
Replace or fix any parts that have been affected.

4. Failure of the EGR cooler bypass valve (or its actuator)

Why: The "circuit/open" problem could be caused by the valve being trapped open or closed or by the solenoid losing power.
How to proceed:
Find the bypass valve, which is often located on the exhaust side next to the EGR cooler.
Examine the electrical connector for damaged wires, bent pins, and rust.
Use a multimeter to confirm that the ECU provides the valve with the appropriate voltage when instructed to do so (see the service manual for precise specifications).
Try gently tapping the valve to release a stuck pintle if it doesn't move. If that doesn't work, replace the solenoid or valve.

5. Problems with the wiring and grounding of both circuits

Why: The ECU may perceive a corroded shared ground strap or harness segment as an open circuit for the EGR bypass, which would distort MAP/MAF signals.
How to proceed:
Follow the ground wires back to the chassis from the EGR-bypass valve, MAF sensor, and MAP sensor.
Replace frayed wires, tighten bolts, and remove any paint or corrosion from the grounding points.
Use a multimeter to confirm continuity; it should read close to zero ohms.

6. ECU calibration and software

Why: These codes can occasionally result in false positives due to a known flaw in the engine control software.
How to proceed:
Verify if the 2014 Evoque SD4 has an updated firmware or ECU flash (see a dealer or official service advisory).
If there is an update, apply it; if not, a dealer can verify if the codes are "known issues" that need to be re-learned.

A comprehensive diagnostic checklist

Use an OBD-II scanner to clear the codes, then drive the vehicle for a brief while to check if they come back.
Examine the MAP sensor and replace or clean it as necessary.
Verify the voltage, clean, or replace the MAF sensor.
Use a visual inspection and a smoke test to look for intake-air leaks.
Check the EGR-bypass valve's mechanical movement, voltage, and connector integrity.
Examine the MAP, MAF, and EGR circuits' wiring and grounds.
After every repair step, re-scan; if a code goes away, you've probably resolved the underlying issue.

If both codes continue after these procedures, there may be a more serious issue (such as a malfunctioning ECU or a concealed sensor error). After that, a skilled workshop equipped with a specific Volvo/Polestar diagnostic tool can conduct sophisticated tests and read real-time sensor data.
A brief "do-it-yourself" synopsis

Clean MAP and MAF sensors are inexpensive and frequently successful.
A major cause of air-flow discrepancies is fractured hoses or unsecured clamps.
Verify the EGR-bypass valve connector; it's easy to overlook rust or loose pins.
Check the grounds; many "open circuit" alarms can be resolved with a clean metal-to-metal connection.

Final remarks and safety

To prevent unintentional short circuits, always disconnect the battery (or at least the negative terminal) before removing sensors or pulling connectors.
After driving, the EGR system may get hot, therefore work in a location with good ventilation.
It's best to leave the diagnosis to a trained mechanic if you're uncomfortable with electrical testing or disassembly.

In summary, the air-intake/exhaust system on the same side of the engine connects the two codes. Before moving on to the EGR-bypass valve itself, start with the most basic inspections (clean sensors, tighten or replace wiring, and fix any intake leaks). Most owners discover that both errors are removed by fixing a loose ground or a dirty MAP sensor. A professional scan and potential component replacement (MAP, MAF, or EGR-bypass valve) will be required if the issue persists.

I sincerely appreciate your assistance and time, and I will go over the list and suggestions you provided.
Sincerely, thank you.
It appears that I also need to buy a few things. Tell me how many beer tokens you require.

I've never heard of DeOxit, but if it works as you say, it's a fantastic concept. Just a small amount of dissimilar metal electrolysis can cause a connector to accumulate resistance, which the ecu will mistakenly perceive as a malfunction and cause these mobile computers to malfunction.
