I have noticed a hesitation from the engine in my B8 allroad 2.0tdi whenever I come up a hill and then start to descent again any ideas what could be causing this?
That's quite difficult to answer without knowing more details. Is it a drop in power, fluctuating revs, manual or auto box. Do you have access to VCDS to scan?
Thanks for quick replies its a drop in power, happens every time I go over a hill near me its the only place I notice the issue. Manual box, no vcds but i'll find someone local with it for a scan
I have noticed a hesitation from the engine in my B8 allroad 2.0tdi whenever I come up a hill and then start to descent again any ideas what could be causing this?
here are some common reasons for engine hesitation that you may want to consider:
Turbocharger Issues:
Problems with the turbocharger, such as a boost leak or malfunction, can lead to hesitation, especially during changes in load like going up and down hills.
Fuel System Problems:
Issues with the fuel system, such as clogged fuel injectors or a faulty fuel pressure regulator, may affect fuel delivery and cause hesitation.
Air Intake Issues:
Restrictions or issues in the air intake system can impact airflow to the engine, leading to hesitation.
Exhaust System Concerns:
Problems with the exhaust system, like a clogged catalytic converter, could affect engine performance.
EGR (Exhaust Gas Recirculation) System:
If the EGR system is not functioning correctly, it may impact engine response during certain driving conditions.
Transmission Issues:
Problems with the transmission, such as slipping or delayed shifts, can cause hesitation.
Sensor Malfunction:
Malfunctioning sensors, such as the mass airflow sensor or throttle position sensor, can impact engine performance.
