My 07 Audi A6L2.4 has some problems recently.

Hello, according to your situation, I give you the following suggestions.

First suggestion: should you still use 20W50 for your oil in another season? It should be 5W30. Oh, is the battery dead or the starter boring? Does it need maintenance or replacement?

Second suggestion: check if your throttle is dirty? If it is a cable throttle, see if the cable is frozen or burr. Or is it the manual clutch?

Third suggestion: This happened twice. The first one is completely normal, because your car burns well and there will be water vapor condensation on the exhaust pipe. It is suggested that you drill a small hole at the lowest point of the exhaust pipe to prevent water corrosion. The second one is not good,,, cylinder gasket,, that is, the waterway is connected with the combustion chamber, and the antifreeze will follow. ! ! ! I hope I can help you! ! !
