I've been noticing a knocking sound coming from my Audi A4's engine. It only happens when the car is at idle and goes away once I start driving. What could be causing this and how can I fix it?
ReplyBased on your description, it is likely that you have a faulty engine mount. This can cause the engine to vibrate and knock against other components when the car is at idle. I would recommend getting it checked and replaced by a certified mechanic.
Engine knocking can also be caused by low oil levels or dirty engine oil. Check your oil levels and if they are low, top it up with the recommended oil for your Audi A4. If the oil is dirty, get an oil change as soon as possible.
Another potential cause of engine knocking in an Audi A4 is a faulty fuel injector. This can cause incorrect fuel mixture ratios and result in knocking noises. It is best to take your car to a trusted mechanic for a proper diagnosis and solution.
