Are these services necessary?
 

Had a free 79 point inspection done on my 2005 A4 1.8 liter Avant Quattro with 46,000 miles by the local Audi dealer--Rusnak in Pasadena, CA .

The dealer suggested that I have the fuel injector serviced ($290.00) and the brake fluid flushed and refilled with new fluid ($190.00).

Are these services necessary? I've never flushed the brake fluid on any of the cars I've owned. Nor serviced the fuel injector.

Are these services necessary?

By the way, I wouldn't know how or want to do the services myself.

They do recommend flushing the brakes, but I've never done it. As far as the injectors go I would put a can of seafoam in the gas and let that do the job. Should save you about $283. Also, watch out for dealer recommendations. Mine told me I needed new front pads over a year ago, I declined, and about 15k later still no problems with the brakes.

The front brake pads have sensor connected to them so it will notify you when they wear down and needs replace. According to user manual (I think I read it somewhere in the manual), brake fluid should be replaced every two years. I just bleed them out myself. I'm not sure about the need for fuel injector; never done it before except changing fuel filter.

I don't think the 02s have brake pad sensors.

It is recommended that brake fluid be changed every 2 years, I've let it go longer and usually not a big problem, but at 50,000 miles or so it is not a bad idea. Brake sensors indicate pad wear and not any fluid issues, so you will not get an indication of anything there. Brake fluid is hygroscopic and picks up water over time from the moisture in the air, it is not good for the system to have water in it.

Injector service is a waste of money. Some folks use Seafoam, I use Techron by Chevron. It is available at almost all parts stores and costs about $10-12. Put it in a tank of gas and you will do the same thing the dealer does for $290.

I just make it a habit to only put chevron gas in the car. Then seafoam every once in a while.

Thanks for all the helpful answers. You saved me about $500.00.

My '04 has it and both 02 and 04 are the same model so I am assuming 02 has sensors too. I could be wrong though. :P

There are a few small differences between the years, even though the cars look the same. It also could make a difference that yours is a 3.0.

02 3.0 definitely has the front sensors...not sure about the 1.8T though.
