estimated cost for replacement and labor for cam shaft sensors x2.

My check engine light, abs,and air bag light is on. I recently had o2 sensors replaced and now the car is running very poorly. There is little acceleration, misfires, and just a terrible sounding engine. i took it to a foreign car specialist who said that the computer is shorted out and needs to be replaced. I need to find out where it is located so that I can get the part number to try to find a used or remanufactured one myself. where is the computer on a 2001 a6 quattro wagon?

The car stopped running a few months ago and had an authorized mechanic look at it and states it needs a new transmission. What should we do and about how much does it cost to relace the transmission?

my dash lights are all most all burned out, how difficult is it to replace them?

I have been told I need to replace ALL the control Arms for

not riding smoothly


I will have added approximately 1 1/2 qts of oil since my last oil change 5k miles ago. I change the oil every 5k miles. It's not burning it as far as I know becuz I passed CT emmissions with no problems.

No leaks that I can see also.

Is this usage normal for this engine?

Thanks for your help.

My 2000 Audi A6 2.7 has a radiator electric fan in front of the radiator that works fine. Then their is the belt operated fan. Their also in the same area to the left of the drive belt fan their is a nother electric engine cooling fan, which does'nt seem to work. What would cause this fan not to work if it's not the cooling fans motor?

I just changed the thermostat, water pump and timing belt because I thought that was why it was overheating. Now the the car still overheats after driven for a long time. Now I have discovered that the engine cooling fan does'nt seem to come on. Could that now be the problem?

I have a 1996 audi a6 quattro. My car guy plugs his scanner in (its the real scanner not the hand held). Once the car warms up it gets a false code (something different every time) Then it shuts down the scanner and we have to reboot it. Very weird never seen a cars computer do that to a scanner before. I was told by other car mechanics that its probily not the computer though. The car runs fine through this whole process and the check engine light stays on, cannot clear it. Can anyone help Thanks ED

After 144K miles had catalytic converters replaced on both sides (4 total) with OEM one piece pipe and cats. After the job was completed an exhaults leak apppeared. After the shop removed the left side pipes/cats and replaced they with another new set the leak was still there. After further investication they told me the left manifold was cracked between the first and second cylinded due to back pressure. It did not have a leak prior to this repair. Is this common? Any advice is appreciated.
