Andy T 0 Posted October 19, 2006 Need to replace this - are the VAG ones better or just the same as the ones from GSF? any differences in longevity? GSF seem to list the same sensor part number for the mk2 8V GTi, G60 & the VR6, is this right? When I've been to GSF in the past for blue temp sensor they never seem 100% if its the right one for your engine, they just say 'oh well it looks the same as your old one so it must be right' !? hmmm.... cheers for any help Quote Share this post Link to post Share on other sites
Andy665 0 Posted October 19, 2006 I have had three blue senders from various suppliers, all have given inaccurate readings - OE ones are more expensive but whats the point of having a temp guage if its not accurate Quote Share this post Link to post Share on other sites
flusted 0 Posted October 19, 2006 I have a gsf 1 but am starting to think i should of bought a vag 1 Quote Share this post Link to post Share on other sites
Andy T 0 Posted October 19, 2006 I have had three blue senders from various suppliers, all have given inaccurate readings - OE ones are more expensive but whats the point of having a temp guage if its not accurate Blue sender talks to ECU for fuelling/timing, shouldn't your temp gauge be running off a black temp sender? they are definately different. Did the blue senders all look different or could they of been made by the same company? Flusted, have you got problems with your GSF one?

flusted 0 Posted October 20, 2006 not sure if i have probs or not but read alot that people say there car ran worse with gsf 1 rather than vag Quote Share this post Link to post Share on other sites

Jim 1 Posted October 20, 2006 Rapidly learning that VAG is the only way.. unless the cost is so astronomical that its more financially viable to buy the cheaper one a few times over! Quote Share this post Link to post Share on other sites
Andy T 0 Posted October 20, 2006 Cheers, thats made my mind up then, I will get one from VAG. Quote Share this post Link to post Share on other sites
flusted 0 Posted October 20, 2006 get a part number and post it up and then il get 1 Quote Share this post Link to post Share on other sites
Andy T 0 Posted October 20, 2006 get a part number and post it up and then il get 1 Just came on to do the very thing.... 1995 VR6 blue temp sensor is 906 041 A, and costs £9.68 + VAT (I was expecting a lot more!) O-Ring seal to go with it is 903 168 02 , £0.87 + VAT. Altogether they come to £12.40 inc. VAT, not bad. When I pick it up tomorrow, I'll see if it looks any different to the GSF ones.

Andy T 0 Posted October 30, 2006 Right,the VAG blue temp sender has the VAG stamp & number on the metal part and marked 'ELFA' (I think) & 'Made in Luxemburg' on the plastic case. Replacing it has definately improved running from cold, before it was gutless for first five mins, I was having to slip the clutch to get going! The GSF sensors have no markings. While fitting the blue sensor I also fitted a new 4-pin yellow temp sensor (from GSF), now the rad fan isn't working after switching the engine off, and the temp gauge is reading alot higher than it used to do. Maybe the new sensor is duff, or maybe the GSF ones are not right for the VR6, will post more info when I get to the bottom of it. Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted October 31, 2006 Blue - ECU fuelling Black - Rad 120 degree trigger (Speed 3) Yellow - Dash guage Speeds 1 and 2 are controlled by the radiator sender. I can't remember what the other outputs in the yellow sender control! Quote Share this post Link to post Share on other sites
Andy T 0 Posted October 31, 2006 I think the yellow sensor controls fan run-on also, as this isn't working with the GSF sensor, but the aux. water pump is working with ignition on. Found that fan is working on second speed at 110°, thats assuming the gauge is reading right on the yellow GSF sensor! Changing the rad sender this weekend.

Andy T 0 Posted November 8, 2006 btw, changing the blue temp sensor has definately cured my cold running problems, it was gutless for the first five minutes on the old sensor and was having to slip the clutch going into second, its spot on now from cold.

Andy T 0 Posted November 12, 2006 Removed the GSF 4-pin yellow temp sensor today and replaced it with a brand new VAG one (now black with blue ring and green dot) Everything is now working as it should (fan run-on etc.) and the temperature gauge is now reading right, as the 1st speed fan is coming on at 95° (on GSF sensor it was reading a worrying 110° before it kicked in on 1st speed!) So I can confirm that the GSF 4-pin yellow sensor (identified by being black with a yellow plastic ring) is not right for the VR6, and it makes the temp gauge read 15-20° too high! I suspected this as the water temp was reading alot higher than the oil temp at all temperatures. Quote Share this post Link to post Share on other sites
madvr6 0 Posted November 13, 2006 good stuff mate, dont suppose you got a part no. for that yellow one? Quote Share this post Link to post Share on other sites
Andy T 0 Posted November 13, 2006 Part no. for yellow sender on my receipt is 701 919 369 D. I think it was ordered off etka under a different number(the old number?), but they are the same thing. Price was £22.37 including VAT, a bit pricey compared to the blue sensor! Quote Share this post Link to post Share on other sites
madvr6 0 Posted November 16, 2006 cool, cheers for that :) Quote Share this post Link to post Share on other sites
