VR6 Lee 0 Posted June 4, 2016 I have just replaced all the below > New Roose motorsport hoses > Heater Matrix > New Radiator and Spal Fans As soon as I switch the engine onto the 2nd turn(lights on dash) the noise in the video starts, in the video the engine is not running but I still get this noise. It does not matter if the engine is hot or cold. The top and bottom pipe of the radiator are both hot so water is circulating correctly. It sounds like water but can't be a air leak. Any ideas? https://www.youtube.com/watch?v=iGL1kGi_A50 Quote Share this post Link to post Share on other sites
Dox 23 Posted June 4, 2016 I suspect its the aux water pump, unplug it and see if the noise stops Quote Share this post Link to post Share on other sites
Jim Bowen 1 Posted June 4, 2016 Yeah sounds like air in the pump. Have you squeezed the pipes, sometimes helps get water into it Quote Share this post Link to post Share on other sites
VR6 Lee 0 Posted June 5, 2016 Yeah sneezed the pipes and noise is still there. The noise is def coming from around the aux pump area so it must be that. I'll disconnect it Sent from my iPhone using Tapatalk Quote Share this post Link to post Share on other sites
VW_OwneR_85 1 Posted June 5, 2016 also make sure the interior heater is set to hot {open} as if its on cold {closed} then it might not be fully bled of air, Quote Share this post Link to post Share on other sites

VR6 Lee 0 Posted June 10, 2016 Just got one from ebay. Brand new Bosch one for £52.99... bargain! Quote Share this post Link to post Share on other sites
Cressa 44 Posted June 10, 2016 Sounds right. Great product and delivery was better than some things from England. And fortunately an easy swap Sent from my SM-G900F using Tapatalk Quote Share this post Link to post Share on other sites
VR6 Lee 0 Posted June 10, 2016 I heard that people delete it off. What are the repercussions of this? Quote Share this post Link to post Share on other sites
Cressa 44 Posted June 10, 2016 I've heard that but why would you. Those German engineers were really clever so it's there for a reason. Circulating the water is good for me. But then again a Tiger tank looked impressive to me growing up Sent from my SM-G900F using Tapatalk Quote Share this post Link to post Share on other sites
