my suspension is squeeking when pressure is applied to it on all 4 corners of the car. what could be causing thing? also my CEL wont stay shut off i keep getting codes 1198 and 1199 which are both for the 02 sensor heater cir. also my air bag light randomly came on out of nowhere.. as well as my abs on solid and brake light flashing, which i know is probably from a dirty sensor but anyone have ideas on the other stuff?

 

Control arm bushings are a known problem and it's a good chance those are shot. You can try some WD40 for a temp fix but look on www.ecstuning.com and price the whole kit. Any driving issues? Pulling? Driving all over the road?
Your air bag light issue could be caused by the plug under seat coming loose or getting dirty. Need to clean it if possible and need a Vag tool to reset your light.
Yes your abs could be from the sensor or the module taking a dump........Pooooooooo.

 

sweet thanks, is there any way to remove it or get it to shut off the annoying brake abs lights so i dont have to look at them. no the car drives perfectly. i also gutta figure out this stupid CEL thing.

 

You will have to get it fixed or they will just keep driving you nuts. Pick up a cheap vag tool off ebay for checking codes and also a Bently book. If you have extra cash which you may not since your having a few issues check out the vag-com system from ross tech.

 

since im new to the whole audi thing can you please explain what a vag tool is?

 

A VAG-COM is like an OBD code reader but made specifically for volkwagen and audi vehicles. VAG standing for Volkswagen Audi Gruppe. Pretty much the VAG-COM from ross tech reads the codes, tells you what they mean, reads tons of sensor info (cylinder temp to angles and stuff) and does all of this in real time. Put the software on a laptop and you can drive with it. Very handy, but pretty expensive.

 

sounds it, i personally woulda picked another name other then VAG tho lol...btw my car started getting squeeky as the weather got hotter and now that i moved to florida on hotter days it gets squeakier.

 

What part of Florida, Nicka430v? If you live anywhere near Georgia and would rather drive to Valdosta than buy the VAGCOM software right away I can pull up your CEL codes and clear them for you. Problem is, they usually come right back within a couple days if the problem hasn't been fixed.

 

nah i live in SW florida. i have cleared the codes at like autozone sometimes they will stay off a couple days sometimes right away, i have a feeling its some type of fluke because one code says volts too high the other says volts too low...sexy r8 i wish i could afford one lol.

 

Southwest Florida, you mean the everglades? lol. I didn't know if you had any manufacturer specific fault codes, I'm not sure Autozone would be able to diagnose those. Thanks for admiring the R8 in my avatar, I wish it were mine, I'd like to think it would be someday.
