    audi a3 temperature gauge problem

    hi i recently fitted a new engine coolant temperature sensor as my gauge wasn't working. cleared the fault code with vcds lite and all was well for a week, now the gauge has stopped working again,did another scan and vcds is reading the temperature fine and isn't throwing any codes so dont think the sensor is bad.have any of you guy and gals got any idea's as what could be wrong? cheers in advance

    Which temperature are you logging? the CTS has two sensors... one for the ECU and one for the dash... you will need to go to the instruments module to log the sensor for the dash...

    Is the CTS an OE one? have seen GSF and ECP pattern parts fail fairly quickly in the past..

    the sensor i replaced is the blue four pin one, i thought 2 wires were for the ecu and the other 2 were for the gauge ?? the temperature reading on vcds were on 17 instrument >measuring blocks >group 3 i think. is this right or i'm i looking in the wrong place..bit of a newbie where vcds is concerned

    Blue 4 pin? is yours an AGU?

    Sounds like the right group in VCDS... if its rising to 90 and the dash needle isn't moving then sounds like the dash is faulty... not sure if something like will throw a fault code... have you check the fault codes in the instruments module?

    If the ECU is seeing temps and the instruments are seeing temps then the issue is the clocks mate

    thanks for the advice,would the clocks just die after fitting a new sensor,could it be a fuse or a short in the wiring just want to be sure before buying new dials:thumbsup

    just a quick update...with the help from youtube and a multimeter How to test a Coolant Temperature Sensor - YouTube i was able to test the ECT sensor, and found out it was bad. lesson learned fit oem parts not cheap ones from ebay. as the cheap one only lasted a week, we now have a working temperature gauge sat at 90.....very nice

    Another way is to check output displays in instruments with vcds. not always conclusive but does diagnose a faulty needle motor
