$1700 cost for valve cover gasket repair at 44000 miles - does this sound right ? Seeing the Part Advertised under $20

My Audio rear parking lights (only the rear) come on in the middle of the night. The first time I had to replace the battery, no big deal it was starting to fade. The second time the new battery held up and I was able to start the car no problem. The light switch was in the auto position for both of these times. What causing this? Does it have anything to do with the very cold temperatures at the time (20 F)?

add these items to estimate

My audi is burning oil very fast and it smells like burnt oil in the cab when i drive. To the best of my knowledge and research this sounds like a leaky valve cover gasket. I am burning at least 2 quarts of oil a month. How easy is that to replace? should a shop do it? how expensive can it be? my email is

My speedometer is not working and the ABS/TRAC lights are on. These three things are all connected; occassionally they all work, but only for about 10 minutes. The check engine light is also on. Audi replaced speed sensor as well another sensor they thought was causing the check engine light. Did not work. They also checked the connections; did not work. Now they are recommending replacing the ABS control module ($2100). Is this really the problem?

When trying to open the hood, the release under the dash works but the release lever in the grill does not allow me to lift the hood. I believe this is just a mechanical lever. Anyone have a trick on getting the release to work?

My moon roof won't close, the motor still makes the sound but , no action when i turn the button to close open or tilt on the moon roof. It's been two days. Where should i take it? What is a good estimate to fix it?

Cant find the transmission oil dipstick to check the oil, why would it be so hard to find? where is it? and how do I add tranny oil?

I have been told by three repair places that my heater core needs replacing, I can't understand why it is so horribly expensive to replace such an inexpensive part. Are there any alternative to make my defroster work? I can live without a heater, but safety requires a defroster here on the coast. I have just spent $5,000 to get the car running without smoking or leaking, so I want to spend as little more money as possible to have a working defroster. Thank you SO much.

Love my audi except for the electrical gremlins!! My cruise control only works when its hot???do I need a new computer control??

cant find where to install speed sensor for speedometer---not registering mph

I noticed that after I had the oil changed in my Audi that it has a smokey smell. I have also noticed that whenever I brake at red lights I can see puffs of smoke coming out from under the hood(it seems to be on the right side) I have no idea if it is safe to drive-there are no lights on and it is not overheating.

I can not get the hood of the car to open. The lever inside pops the hood but the front latch doesn't seem to be releasing. I would hate to pull too hard and break it. Any suggestions?

I bought this 2005 A4 new and it now has 32,700 miles. The dealer recommend a timing belt replacement but is it necessary with so low miles? What should a job like this cost?
