How to troubleshoot common issues with the Vauxhall Vivaro's engine?

I'm having trouble with my Vauxhall Vivaro's engine and I'm not sure what's causing it. What are the most common issues that could be causing this and how should I approach troubleshooting?

First, check for any warning lights or error codes and use a diagnostic tool to narrow down the possible causes. It could be a faulty sensor, fuel pump, or ignition coil. If no warning lights are present, start by checking the fuel filter and spark plugs.

If the engine is not starting or is running rough, it's possible that the battery has died. Check the battery and its connections. If everything looks good, it may be time to replace the battery.

Sometimes, a clogged air filter can cause engine issues. Remove the air filter and inspect it for any dirt or debris. If it looks dirty, replace it with a new one. Also, make sure to regularly change your air filter according to the manufacturer's recommendation.

Low oil levels or dirty oil can also lead to engine problems. Check the oil level and condition, and top up or change the oil if needed. It's important to regularly maintain your vehicle's oil to ensure proper engine function.
