Major Electrical Prob by joey_i

Recently I've bought myself an audi a4 quattro 1995.
it's got some sort of electrical problem, and the car won't start. I'm thinking it's got some issues to do with heat, because the car only starts at night, or when it's cool. usually I take the car out at night, and dawn, and most of the time (95% of the time) it never starts in the day, because it is a bit warm here. some people tell me it's the starter, and the dirt needs to be cleaned off, to reduse overheating. but I think it's much more than that...anyone have any ideas?
 
Any help is greatly appreciated.

If you mean the car won't CRANK (starter motor doesn't engage, you turn key and nothing happens) when it's warm, then yes, you'd want to look at the starter relay and also check all battery connections at the battery and to wherever the connections attach on the other end.
 
If you mean the car CRANKS OVER (starter motor turns) but the engine doesn't catch, then you probably have an ignition component failing or a bad fuel pump that is binding when hot.

yeah the car wont crank, so when I turn the key, nothing happens. but I hear long beep sound coming from near the device (excuse my bad descriptions, dono much about these things) where the accelerator cable is connected to. Don't know if this may be the problem, but my ignition lock is a bit dodgy, and sometimes I have to push the key in harder to start the car. but this only works on cool days, when its warm or hot, this method does nothing.

Exhaust Smell by moerucus

When I am driving my husbands 99 A4, there is a strong exhaust smell whenever I have the defrost or heat on, it is horrid. It is so strong and it really bad when the car is not moving. Like when we are stopped it is so bad I can't have the heat on. Could someone give me an idea of what I should do. It also shifts late, or really hard sometimes and lacks power, unless i stomp on the gas. ?????? Thank you.

You would have to have the car run up onto a lift and then, while running, a mechanic would plug the tail pipe with a rag and then listen and look for an exhaust leak somewhere in the system.
 
Exhaust leaks are dangerous and should be investigated right away.
 
sometimes people mistake an oil leak dripping on a hot exhaust pipe for an exhaust smell---they are similar,--so I'd also check for an oil drip somewhere.
 
Don't mess around with this kind of problem...

My current issue is that the car doesn't start. I went to the gas station last Mon. before class and filled the tank and right when I was trying to leave the car wouldn't start. I recently replaced the battery. All the car would do is make a buzzing noise inside the cabin when I turned the key. Can anyone shed any light on this issue.

Alternator by joey_i
Mar 27, 2009 (9:43 pm)
Reply
I was wondering, does my audi a4 quattro 1995 have a starter motor seperate to the alternator, or does the alternator work as a starter motor aswell...if it is a starter motor aswell as an alternator, how do I test if its working properly with a multimeter? Because recently my car isnt cranking and I have a new battery.

To Buy or Not To Buy by audinewbie

Is $20,300 for an '06 A4 3.2L S Line with 56K miles (mostly highway) a deal, or is it too good to be true? The car is extremely clean and in almost brand new condition, but that seems like a lot of miles. Thoughts and feedback are appreciated.
