hey, so i bought this audi 90Q last summer it and has been throwing the CEL whenever I get up to highway speeds. I figured it was just from the exhaust leak I have or the 02 sensors and when i checked the codes they were:

00281 Vehicle Speed Sensor
00282 Throttle Valve Posistion Sensor
00513 Engine Speed Sensor

Is anyone familiar with these codes, and if they're something to be concerned about? Thanks for any help!

This is from the B4 ('93-'95) Bentley...there's no code/description for 00282

00281:
- Vehicle Speed Sensor (VSS) -G68- faulty
- Wiring connection between G68 and speedometer G21
- Speedometer G21 faulty
- Wiring connection between instrument cluster and Engine Control Module (ECM) -J192-
- ECM faulty

00513:
- Debris on Engine Speed (RPM) sensor -G28-
- Sensor G28 holding socket loose
- Distance from G28 to flywheel ring gear greater than 1.2 mm (3/64 in.)
- Broken teeth on flywheel ring gear
- Open circuit between 3-pin connector in engine compartment and G28
- Open circuit between ECM J192 and G28
- Short circuit between connector C terminals 1, 2, 3, and J192 and/or shielding or ground
- Open circuit in G28 shielding

1995 I got the descriptions but is it something that I really need to worry about? I mean could this be a cheap fix or worth it if the car isn't even running bad?

Well the codes are being thrown for a reason...I'd figure out why before the car leaves you stranded
