If your VW T4 won't rev, it could be due to several reasons, including a clogged fuel filter, a malfunctioning throttle position sensor, or issues with the air intake system. Additionally, a faulty mass airflow sensor or a vacuum leak could restrict airflow, preventing the engine from revving properly. It's advisable to check for any warning lights on the dashboard and perform a diagnostic scan for error codes to pinpoint the issue. Regular maintenance, such as checking fuel and air filters, can also help prevent these problems.
