Hello guys! A few months ago I had a completely dead battery around 1V. It was 70Ah, so the new one I got was 74Ah if that makes a difference. After that, I also changed the interior fan control because that was actually draining my battery in the first place. All was fine until I noticed that...

Hi guys So i just did a clutch fan delete and also a mishimoto fan controll for the cluster fan because I just finished a head gasket job and complete cooling overhaul. Now with the fan turning on at 90 degrees temp, Full Power! my temperature still goes up to 97 with the heater on and when i...

Hi all, I’ve got a 2002 M3 but I’m posting in the general forum as the same thing could maybe happen with any model. So the issue. The car has been in storage for a couple of months but I needed it about a fortnight ago. All was good when I put it away and it started and drove fine when I got...

Hi there, Was driving home from work a few days ago and got stuck in some standstill traffic. Was not really paying much attention, until I looked up and noticed my temp guage was lit up (yes, I didn't notice until the light was on). I immediately turned off my car but didn't have a place to...

My computer displayed temperature is fixed at 50.0 Celsius non stop. Anyone have any idea why?

Hi everyone. I'm after some advice on what to do with my car. Background is that it overheats on the gauge up to the 3/4 dot, or on the "hidden" dash functions up to 100-103 degrees. BUT it only does this on hot days 35+ degrees in Sydney Australia. So in Winter it's fine, if it's 25...

Hey guys, I'm having a bit of a strange issue with my 2001 325xi. I first started getting this P0128 code that suggests that my thermostat might be stuck open. I looked it up on the forums and then found that i should probably replace the Thermostat, so I got myself an eBay thermostat (no...

Today was a pretty hot day around here and I was stuck in traffic at noon for a nice 45 minutes surrounded by other 300 running cars. I became concerned about the temp raising due to being stuck, with 90F outside and the A/C on so I used the hidden OBC. To my surprise, the temperature was a...

Hey guys and gals, The YouTube channel "B is for Build" is currently patching together a 2001 e46 325i for Oregon's "500/500 Rally", where one takes a $500 car and drives it for 500 miles on fire roads and whatnot. Anyways, Chris of B is for Build has built a custom cooling system, but he'd...

Hi guys, I have an 00 323Ci and when I got it it need ed the cooling system replaced. So I replaced it and the fan to. Sadly I think I went with an afterror market replacment. The problem I'm having is that it never turns on. Not when I turn ac on or when it gets hot. I checked the fuses today...

Was wondering what the appropriate coolant/engine temperature range is in *F. My car is running at, what seems to be a high temperature range (240*F-275*F), but my coolant gauge says it is perfect (right in the middle of cold-blue and hot-red). If it is true about my suspicion, what do you...

My outdoor temp usually reads about 15/20 degrees F low. On hot days it can get up to a 30 degree difference. The thing is it still changes normally, it'll just say 24 degrees F when its around 40 degrees. Or 57 degrees when its 85 outside. I checked the sensor when I washed my car today and...

Hey everyone, got a pretty serious issue here. Earlier I had to replace the temperature sensor for my car because my OBD reader was giving me the fault code P0070. Well I replaced it and reset the code and all was well until the light came back on after a few miles. :banghead: I scanned it...

A lot of people over at M3Forum have been discovering the benefits of relocating the temperature sensor that is built into our MAF's that often heat soak after a short time of driving decreasing performance (timing) and not being able to give a accurate reading of what the true temperature is...

Hey everyone, I got a little problem with my ambient temperature sensor. A while back I let my friend drive my 325i :thumbdwn: and he crashed it.:facepalm: I guess somewhere between the time of impact and him driving off my temperature sensor was lost. After that my SES light came on and it...

Okay i have no clue what is happening, my e46 m3 keeps telling me that its 120 degrees outside and it beeps then it says is -9 degrees and when it alerts me my ac stops working, then it will start working again and blow cold for a while, then it beeps and stops again! what is happening?! I also...

Hey guys im trying to install an aftermarket temperature gauge as i have been having a few cooling issues these past few days and want to keep a closer eye on the temperature. Im thinking of installing one of these, Replacing the bleeder screw with its sensor...

my car issue is that fuse 28 keeps blowing occasionally in summer. according to my experience, it happens when the car is parked under sunlight(say, 33degC or above) outdoor, comes across traffic jam under sunlight (outside 3x degC or above) or is parked at indoor car park(high temperature, say...

OK, I've read a couple threads about low temp gauge readings on the console and have three possibilities. Backgound: This is a 2000 323iT with less than 100K miles and decent (not perfect) maint over the last 10 years. Had a big coolant system replacement at about 70K, a few years ago, due to...

HELP!!!!! I have a 2005 M3 Cabrio SMG with the all of the basic Turner Motorsports mods (intake, exhaust, pulleys, Shark programmer, Bilstien suspension, brakes, adjustable camber plates, etc.). It is my daily driver and I track it when I can. I have a problem with the temperature going up...
