I noticed that my Audi A2's diesel engine has a loud tapping noise, especially when idling. Is there something wrong with my engine? Is it something that can be fixed easily or do I need to take it to a mechanic?
ReplyIt is possible that this noise could be caused by a lack of lubrication in the engine. It's important to check your oil levels and top up if necessary. Additionally, the tapping noise could also be a sign of worn out valves or lifters. If this is the case, it's best to have a professional mechanic take a look and diagnose the issue.
Another possible cause could be a dirty fuel injector. You may want to try using a fuel injector cleaner to see if that helps with the noise. If not, it's best to have a mechanic check it out to ensure the issue doesn't get worse.
In some cases, the loud tapping noise could be a result of a faulty timing belt or tensioner. It's important to have these components checked regularly and replaced if necessary to avoid any further damage to the engine.
