The customer reported that the check engine light was on in their 2014 Land Rover Freelander. After connecting a scan tool, a P00B8 code was found, indicating a correlation issue with the mass or volume air flow. A subsequent road test revealed a hissing sound, prompting a smoke test that identified a leak from the damaged charge air cooler hose. The hose was replaced, codes cleared, and a successful road test demonstrated proper vehicle operation with no fault codes or warning lights.

Replaced the faulty air suspension compressor on a 2019 Land Rover Range Rover Sport 2.0L Petrol after diagnosing code C1A13. The ABS light was on, and testing confirmed the compressor did not respond. After replacement, codes were cleared, a road test was performed, and the issue was resolved. The ABS light remained off, and no fault codes returned.

A 2015 Audi A1 1.0L GB had a check engine light due to a faulty electronic throttle control motor. Diagnostics confirmed code P1558, indicating an electrical malfunction in the throttle actuator. After verifying voltage and testing the throttle valve, the faulty motor was replaced. A road test confirmed the fix, with no returning fault codes or issues.

A 2021 Opel Vauxhall Movano 2.3L Diesel arrived with a check engine light and code P0400-00, pointing to an EGR valve issue. Diagnostics confirmed the valve wasn’t functioning properly. After verifying wiring and applying direct voltage, the faulty EGR valve was replaced. A road test confirmed the fix—no more check engine light or returning fault codes.

Monitored live data using a scan tool to shed light on the low flow warning. Found the exhaust gas recirculation valve was inoperative. No loose connections or signs of damage were found on the surface, but after removing the valve, it was clear clogged carbon was the true culprit of the Ford Mondeo’s low flow.

A Scan tool revealed code P1206 – Diesel Particulate Filter Efficiency Below Threshold, and after monitoring live data the filter pressure sensor signal revealed erratic parameters. This indicates a potential fault in the sensor or circuitry. Continue reading to discover the multi-meter tests and other procedures used to complete the fix.

Trouble code P0597-00 indicates an Engine Coolant Thermostat, Cooling system error. But what is the fix when the coolant level and condition show no faults? An infrared thermometer is used to identify temperature below specification in the housing inlet and outlet. This communicates an opening is present, so the next steps are to verify the faulty part and replace it.

With the initial warning brake light on, it was clear some mechanism within the electric parking brake was causing the illumination. Using a scan tool, the code U1219 highlighted the permanent fault that the automatic release was experiencing. By leveraging live data monitored on the scan tool, it was found that the parking brake switch data and the pressing of the switch were not in sync. Continue reading this real fix for the remedy and part replacement procedure.

Even with a DTC indicating low engine oil, the fix is not always apparent on the surface level. This 2019 Stelvio had an oil-level sensor signal wire exhibiting erratic signals to the lab scope. The sensor was proved to be the true culprit of the P250F trouble code. Read the full real fix to learn the proper diagnostic steps to take.
