Jon94VR 10 Posted October 23, 2012 Had the car vagcom'd the other day and the only thing on there was an intake manifold temperature sensor fault, so changed that and now the fan is on permanently, any ideas? Quote Share this post Link to post Share on other sites
nrc 0 Posted October 23, 2012 What stage is the fan running at when it comes on (how loud is it)? Does it run when the ignition is on but before the engine is started? Quote Share this post Link to post Share on other sites
Jon94VR 10 Posted October 23, 2012 Quite loud, can hear it all the time, sounds like a hoover! Yeah it comes on when the ignition is on before the engine is started Quote Share this post Link to post Share on other sites
nrc 0 Posted October 23, 2012 Do you have 3 senders in the thermostat housing at the front of the engine? I wonder if the connectors for the intake temp sender and stage 3 fan (rightmost sender in the housing) have been mixed up... Quote Share this post Link to post Share on other sites
Jon94VR 10 Posted October 24, 2012 Thermostat looks ok, had the car vag-com'd today as only had normal code reader on it, still throwing up the same error, though its saying open to plus on the intake manifold temperature sensor Had a look at the sensor and the plug barely stays on it tbh, as I work for ECP got one from there, but think I'll go and get a geniune one from VW and try that out, unplugged it for now as the fan was doing my head in! Luckily not using the car till the weekend so got time to sort Quote Share this post Link to post Share on other sites
Jon94VR 10 Posted October 29, 2012 New sensor sorted it all out, cheers for the advice Quote Share this post Link to post Share on other sites
