check engine light on

Hello,

Please direct me to the proper topic area if I am misposting.

I'm looking at buying a 1997 A4 2.8 5speed w/ 186,000 miles. The cars drives, shifts, and looks very smooth inside and out. One problem. The check engine light is on. I had a dealer hook up the computer and read the chip. "Sensor Heater Circuit Malfunction" was the only error. Sensor 2 to be specific. I have no idea what this is or how serious/expensive it is to fix.

Also, In the drivers display cluster the very center display (the large one) displays a large flashing temperature symbol. Is this the A4's way of saying it's overheating? The test drive was awesome. Engine sounded sweet but I'm a computer guy not a mechanic.

Can someone please advise? Thanks in advance!

low on coolant, that code means needs new rear o2 sensor (not a big deal)

So it's not one of those $1200 dollar fixes that some people have told me Audi's are famous for?

Also, about that large flashing temp icon in the display. Is the car overheating?

Thanks for replying!
