p0l1wrath 10 Posted May 30, 2012 (edited) Hello, i have a problem and have looked around and found many solutions, but i wondered which one is the fix for my car? currently when i plug in the vag com in i get error -00522 which is a problem with -givers for coolant temperature -G62 my engine temp on the vagcom and dial is almost always 77.ºC my fans hardly ever kick in (can only assume because engine "isnt getting warm enough") sometimes it all suddenly works eg. sat in drivethru worrying about engine temp, then dial moves to correct temp and fans kick in *Phew* i assume my problem could be with the Engine Coolant Sensor? if so where is this? is it one of the plugs above the thermo housing? which one? Thanks Edited May 31, 2012 by davidwort Quote Share this post Link to post Share on other sites
Supercharged 2 Posted May 30, 2012 What car do you have?? The sensor VAGCOM refers to is for the ECU, the gauge one is seperate. I'd start by replacing the sensor and thermostat along with a coolant refresh. Quote Share this post Link to post Share on other sites
seanl82 23 Posted May 30, 2012 Yeah if your temps are low and don't rise unless your sat in traffic, then 9 times out of 10 its a dodgy thermostat. Quote Share this post Link to post Share on other sites
p0l1wrath 10 Posted May 30, 2012 oh yeh sorry vr6! ok well so is the gauge one a seperate problem all together? and ok ill get that done then :) cheers Quote Share this post Link to post Share on other sites
p0l1wrath 10 Posted May 31, 2012 is the sensor the blue 2 pin one? the middle of the three? Quote Share this post Link to post Share on other sites
Critical_Mass 10 Posted May 31, 2012 The blue one is for the ECU. There is a yellow (or black if its been replaced previously) is for the gauge. If you change the yellow one then the new one will be black with a blue ring round it - 4 pin i think. Quote Share this post Link to post Share on other sites
p0l1wrath 10 Posted May 31, 2012 pretty sure ive got three? from left to right, yellow 4 pin, blue 2 pin, black 4 pin? Quote Share this post Link to post Share on other sites
Critical_Mass 10 Posted May 31, 2012 Yup there is three. Forget what the black one is for. The yellow is the gauge and fans, but if replaced for new will be a black one. The blue i the ECU. Quote Share this post Link to post Share on other sites
p0l1wrath 10 Posted May 31, 2012 ahhh! gauge and fans! but would the vagcom read from the ecu though? Quote Share this post Link to post Share on other sites
Critical_Mass 10 Posted May 31, 2012 Yes vag come reads the ECU for the temp. Quote Share this post Link to post Share on other sites
Album56 0 Posted June 1, 2012 Try replacing just the thermostat 1st. Tired or faulty thermostat can cause all your symptoms. Quote Share this post Link to post Share on other sites
