Question Answered: How much does it cost to fix my squeaky belt or pulley?
June 26, 2012, 03:16 PM
Do yourself a favor, pop your hood, grab the belt, see if it moves up and down. It should not move more than half an inch in either direction. If it moves more, Tighten it(adjust). Look for cracks. If it looks good, go down to your local auto parts and by a can of Belt Eze or other. Spray some on the belt. Start car. If noise is gone, Then you will know for sure if the belt is bad. Checking for a bad pully, Remove the belt, turn each pully fast by hand, listen for noise. At least you will know for sure what your problem is. Goodluck, Help4u
Question Answered: My Bose Audio required a reset code on my 1997 MB SL500. Can i get CODE ON WEB?

Unfortunately, if you do not know the privious owner, you will have no way of knowing what code they may have entered for their ID. Usually, if you contact Mercedes, they can help you with a deactivation code. They will need to know the VIN#, all their sterios have a computer system and remembers the car it went in when new. I dont know of any other way to access the system. Wish you a lot of luck. Help4u
Question Answered: I am getting a hot (exhaust) smell from under the vehicle middle to back
June 26, 2012, 02:37 PM
Trouble shooting this could be unsafe. Raise vehicle on side then block up.Look for broken hangers which could cause the clamps to loosen up. Visibly, they would look okay. Have a friend start it up. Start running your hand all around the pipes at all connection points( keep about 2 inches away) If it is leaking, you will feel it. If it had to do with EVAP, it would code out. If it had to do with O2S, It would code out. If you are feeling unsure, take it to your local Muffler shop. Goodluck, Help4u
Question Answered: Why would a starter not engage when car is hot and had been sitting in sun?
June 26, 2012, 02:12 PM
First thing you need to find out is if you have a good starter. Mark the wiring, remove starter. Now bench test it. Remove the battery. place starter next to battery. get jumper cables. connect negative cable on Batt Negative,other end to any portion of the starter away from connection posts. connect Positive cable to Batt positive and other end to starter where the cable was removed,usually the largest post with no cable attached. Connect a jumper wire to Positive Cable anywhere. The only post left is a small post. Thats your signal post for the signal wire to connect from the key switch. You are going to quickly touch your other end of the jumper wire to this post. Do it quickly, if it turns over, it's good. If not, It's bad. Make sure you touch it at the tip of the post and not on the threads. Now you will know if it is good or not. When you get a new one, always bench test first. Just because its new, doesn't mean it's good. Goodluck,Help4u
Question Answered: Carbon Build up
June 26, 2012, 01:06 PM
You may want to think about a major tuneup. You have a 7year old car and 100k miles. I'd say you are doing ok. Instead of checking the internet and getting upset, get out of your seat, call up your favorite Mechanic, have him give you a free estimate. This is not an ongoing problem that Audi knows about. This is a problem that every owner of a vehicle goes thru. It's now your turn._____About Carbon buildup in an engine? Quite common. Some of the By-products of Oil is Gas and Carbon. Not all Carbon is expelled out of the exhaust system..We cannot Defeat it, we can only try to control it. Goodluck, Help4u

Question Answered: got new battery, still won't hold a charge,what should next step be?
June 26, 2012, 12:16 PM
You have 2 prolems(unrelated). First step, always check your charging system Prior to Replacing your Battery. Your Alternator should be puttting out about 13.2 to 13.5 volts(some may be as high as 14.2 volts). Check your battery cables. If they have a powder residue on them, clean them with water only.(Not baking soda or pepsi or coke)I've heard it all. Check the plug going to the Alternator and the cables.Make sure they are clean and tight.Dont just look at them, take them off and inspect. Check your Negative cable from the Battery to the Frame or Block and clean it. Have someone with a Volt Meter check battery volts, with meter still attached, start Jeep, volt drop should be no less than 3 volts. With it running, it should show over 13.3volts. Cables and Wiring cause more Battery and Alternator Failures than anything else. Dome Lights are connected to the switch on the side of the Frame so when the door closes, it pushes in the switch and turns off the light(Normally Closed) switch. It could be as simple as a dirty switch. Remove the switch and test. Put your meter on 2k ohms setting. You will see a 1.,which means broken wire. Connect both meter leads together, you will see three zeros, letting you know that you now have a good wire. Now test the switch the same way. If you get different readings, its working, if it stays the same, its bad. Replace with correct part. Good Luck. Help4u
Question Answered: what could happen and how could ytell if the thermostat was in backwards thanks
June 26, 2012, 10:43 AM
Thermostats are cone shaped on top and cylinder shaped with a spring on the bottom. Make sure the cylinder/spring goes into the block. The cylinder/spring portion is the temp sensor.When it reaches the correct temp, it opens up by pulling down on the cone shape and allowing hot fluid from the block to pour into the radiator, at the same time, it pushes the cool fluid from the radiator into the block thru the lower radiator hose. If you had it reversed, you may end up with more problems than you want. Possible blown head gasket, cracked block
