Have a problem with the auto check system (Audi V8-89 3.6L ) When I'm pressing the check buttom only the signs for

translatet with google:
The CAT light came with my V8 already times. In the Katalisator a temperature sensor of these sits was defeckt, I the temperature sensor changed and the errors was repaired with me. Because also with me was to be determined nothing by engine misfire or overheating of the CAT's. Hope you have the same error leaves itself simply repair-wish further good travel.

Thank's for the reply,I'll try a new temp.sensor.
Have changed the rpm and timing sensors and the lamda sonde.But it didn't help,the cat light was / is still flashing.
The light starts to blink same second I start the engine.
Even if the engine is cold.
Do not think the catalytic converters can be overheating
in 5 seconds.So I will change the temp sensor and see
what happens.
Thank's again,,

Hi,
the reason for your AutoCheck-Display not showing the yellow symbols (The "OK" an so on) could be very simple. The are two bulbs for the AC-Display: one with a red coating and one with a yellow one. The yellow one could be broken.
Unfortunately you have to dismantle the instrument cluster in order to check or replace the bulb. As a result you have to remove the upper part of the dashboard, too. Yes, this IS a crappy design...
Bye,
Jens
