blackturboblack Posted April 2, 2011 Share Posted April 2, 2011 I know this may sound crazy, maybe silly to some, but I can't figure out what that small blue light is on my temperature gauge. I can't find it in any manual I've read. Not even the "vacation pictures". Obviously it has to do with the fluid temperature. But which fluid? Oil? Anti? It goes out as the car heats up. I just got a turbo upgrade and I started wondering if it means don't drive until the light goes out indicating the oil is sufficiently warm to protect the turbo when it spools. I don't want to eff up the car. What is this light for? Link to comment Share on other sites More sharing options...
rtbrjason Posted April 2, 2011 Share Posted April 2, 2011 It means the coolant is under 136 degrees. You can't switch to S# until the light goes off.. Link to comment Share on other sites More sharing options...

Where did you find that info, if I may ask. And I'm assuming that doesn't mean I can't just get in and drive. Link to comment Share on other sites More sharing options...
ehsnils Posted April 2, 2011 Share Posted April 2, 2011 You can drive the car, but don't floor it until it's warm. Link to comment Share on other sites More sharing options...
wizkerbizket Posted April 4, 2011 Share Posted April 4, 2011 Pretty sure its in the manual. Thought thats where i read it anyway... Link to comment Share on other sites More sharing options...
Tomkat1127 Posted April 4, 2011 Share Posted April 4, 2011 It is in the manual (not sure what page). It is there to tell you when the car has sufficiently warmed up to the point where you can rev the engine or get into heavy boost. I personally try to stay under 4K RPM until this light is off. Not sure but I would say it also has to do with emissions. A (typical properly functioning) cars worse point of pollution (and wear) is from cold start-up to warm up. It takes some time for the catalytic converters and O2's to come up to temperature and put the car into closed loop mode. Until then the car is stickily running off the ECU fuel maps. Since the 1990's cars have used 3+ wire heated O2 sensors and are programed to run to reach the closed loop mode ASAP. Sorry, for the long response. Guess I spent too many days explaining O2 and cars to morons (I mean customers) in a parts store. Link to comment Share on other sites More sharing options...
blackturboblack Posted April 4, 2011 Author Share Posted April 4, 2011 Thanks guys. I've gotta go through that manual again. At least I had the sense to know it meant SOMETHING about not driving WOT, so I'm relieved I didn't do damage. Especially with the new snail I put in.

longislander1 Posted April 4, 2011 Share Posted April 4, 2011 Dealer told me the blue light thing is normal on all cars, at least the newer ones. I had an Impreza loaner once and first thought there was a coolant problem. I had the same blue light go on until warmup on a 2011 Legacy loaner.

ehsnils Posted April 4, 2011 Share Posted April 4, 2011 Problem lamps are red or sometimes yellow, other colors are nothing to worry about. There's even an ISO standard specifying the symbols and colors. Link to comment Share on other sites More sharing options...
Tomkat1127 Posted April 4, 2011 Share Posted April 4, 2011 They are nothing new. Wife's 2000 VW New Beetle had one, that's over a decade ago. Link to comment Share on other sites More sharing options...
Instanced Posted April 4, 2011 Share Posted April 4, 2011 E46 BMW's (M3) and Honda s2k's (I think) actually limit how many rpm's you can rev the car to until it's warmed up, E46 is cool because as the temp goes up the limit (redline) goes up until the true redline of the car... love that feature!

elib Posted April 5, 2011 Share Posted April 5, 2011 That's the no-hooning light. Can't do power slides, burn outs etc until it's out. I love the new super cars that won't let you use launch control etc until the DIFFs, tranny and other parts are up to temp, not just the coolant. i.e. if you let the engine warm up but the tranny hasn't moved it's not great to do a hard launch as the lube hasn't been spread etc. Link to comment Share on other sites More sharing options...
tito_b0y Posted April 7, 2011 Share Posted April 7, 2011 Is this light only for the turbo models? 2006 SWP 3.0R 5EAT VDC BBQ 2008 OBP 2.5i 4EAT BBQ [RIP] Link to comment Share on other sites More sharing options...
TooBigToFit Posted April 7, 2011 Share Posted April 7, 2011 Is this light only for the turbo models? I believe it's SI-Drive cars only (3.0R, 2.5GT 07+). Its official name is S# PREP, if I recall correctly. No fun button till it goes off Link to comment Share on other sites More sharing options...
blackturboblack Posted April 8, 2011 Author Share Posted April 8, 2011 Launch mode. Hmm. Now how would I program my car with Cobb AP to launch? Or is that a separate thread/forum? Link to comment Share on other sites More sharing options...
