In this video, you will learn how to clean the throttle body of an Opel/Vauxhall Zafira C: you will need a specific cleaner like LiquiMoly Pro Line, which can be found on eBay with code 317155905311, priced at £19.90 with free delivery; gloves and lint-free cloths; a star screwdriver, long-nose pliers, and soft-bristle brushes.

Turn off the engine and disconnect the battery, then locate the throttle body, which in petrol engines is found between the air filter and the intake manifold, while in diesel engines it is connected to the EGR, often with an integrated MAP sensor.

For disassembly, remove the air hose by loosening the clamps and disconnecting the post-air filter hose, disconnect the electrical connector, and remove the PCV valve. Spray the cleaner inside the throttle body (avoiding forcing it manually).

Let it sit for about ten minutes to dissolve carbon deposits, then remove the dirt: the MAP sensor must be cleaned with a specific spray. Once cleaned, reconnect the electrical connector and the air hose, along with the PCV valve hoses.

Reconnect the battery, turn on the ignition, and wait a couple of minutes for the throttle to self-calibrate, then start the engine and let it idle for 5 minutes.

Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat.
