3- Failures in the clutch
The direct shift transmission in the Audi A3 uses a dual-clutch automatic gearbox. In many of the cars made between 2008 and 2009 there is a recognized fault in the clutch temperature gauge, which triggers it when the car gets hot, causing the vehicle to lose power on the road . Audi recalled several vehicles and reprogrammed the part’s faulty chip.

It is caused by excessive wear on an oil pump sprocket and can occur almost any time. You will have to buy a replacement oil pump and replace the worn one.
10- Loss of power
The car starts to lose power while driving. The clutch temperature gauge on automatic vehicles has a frustrating habit of coming on at random times. This causes the car to lose power .
Audi recalled a large number of A3s for this reason, and it is caused by a faulty chip. You will have to find a replacement clutch temperature gauge and replace the faulty one.

If the check engine warning light has appeared on the dash, it is usually caused by the coolant temperature sensor . If this is the problem, you may also notice that you are having trouble starting the car when it is hot, or that you are getting strange temperature readings. You will need to replace the coolant temperature sensor, to resolve this issue.
