Anyone in Myrtle Beach with a WiFi ELM327 URGENT

I forgot to pack mine in my flight bag. Anyone in the area got one I can borrow till Wednesday or even a Carly adapter. I ordered another but it will take that long to ship here. If you can - you can use the lift for a day to work on your car.

I leave adapters in some of my cars so there is always something on hand for my car or for me to use on friends or family vehicles.

You working on the E90 still?

Hi James - Yep - I have a Snap On Solus here in Myrtle but the cheap WiFi and OBD Fusion dashboard is perfect for monitoring running conditions with my iPhone - I'm still worried about this car overheating. I haven't figured out the normal cooling characteristics with the electric pump. It is totally different than an e46 that would see cooler temps at highway speeds and hotter temps in stop n go due to the air movement and water pump speed.

This e90 gets up to 105C at highway speeds and can drop as low as 87C in stop n go. This was the case 2 days ago in 94F temps in heavy traffic then on the freeway. It seems to average around 99C. AC on or off doesn't seem to have much effect. It hasn't overheated but the engine bay is HOT and the hoses look hard at times - problem is I don't have enough comparison knowledge with this engine - my X3 has the same engine and doesn't seem to get this hot but I've never monitored it and seldom drive it.

The N52 documentation supports this pattern for fuel economy but to me it just seems inconsistent with what I am used to with belt driven (RPM dependent) mechanical water pumps.

A forum member loaned me a WiFi dongle and I'm at the shop now and the postman just dropped off the one I ordered Thursday, so I'll take it back to them on Monday.

While my E93 is a 2013, not sure if there are any differences, the quick and dirty data I gathered was no where near as high as your numbers.

As far as I am aware, at 22k miles nothing other than the oil has been changed on my car.

Not sure if the thermostats are the same part number over all of the models or not?

If you can get me a some .CSV Log with the Temp, RPM and Speed and tell me what the ambient temp was, I can try to replicate the same conditions on my car. The problem is up until sometimes next week, we have had very mild temps, today we are looking at 55F.

I think next week we may finally hit 80+F.

Did you by chance rinse and/or clean/check between the AC condenser and radiator??

What happens to the engine temps if you spray the radiator down at idle? Do they quickly drop?

Used a garden hose to spray the rad when it got up around 91C - didn't have any effect. Odd though - this has a new T-stat and verified WP and the lower rad hose was significantly cool to touch compared to the rest of the system up top. No errors from either WP or T-stat. On my X3 the WP put out an RPM & flow error to signify it was time to change. One would think the cooling system being sealed would be impervious to a flood?

Sounds like the thermostat/flow is not real active otherwise the cooling the radiator with a garden hose would cause the temp to drop at least to some minimum.

What temp was the engine running when you attempted to cool the radiator?

Do you think the temp sensor/connector was submerged in the flood water?

It appears like a circulation issue but I see the WP spewing coolant into the ET with the electric bleed. Possibly the old and new T-stat not functioning properly??

I cooled it a few times with the hose. First at 91C - little effect - held that temp a while longer. Then again at 95C and 97C - same results. The Cooling temp sensor was changed twice. This car has only one. It works good cause I cooled the area around where the temp sensor goes into the housing and the temp dropped dramatically 10C then went back up when I stopped.

Monday I'll flush the rad again and see if there is a way for me to put in an open flow t-stat just to see what effect that has. The tstat here works a little different where DME does control opening and closing more frequently in combination with the WP flow rate. The fan is kicking in and likely saving an overheat at this point.

What I don't get is why in stop n go the engine runs cooler unless DME is opening the T-stat more????

It appears to be solved. For the past few days I've been monitoring engine temps in my submarine e90. They have ranged from 87C to 107C inexplicably. On Monday I went and ordered a new WP and Rad but was reading this morning some more documentation when it hit me like a hammer. - I've wondered why this car does not have a Coolant Temp Sensor on the lower rad hose. It only has what it calls a CTS up near the oil filter.

So where does DME get multiple input to determine when to activate the electric wp and the electric fan? I know from experience that DME always uses more than one input in case one fails. I read this morning that the Oil Level Sensor in this car also measures engine oil temperature. Aha! - DME uses this data for calculating the WP output. (Speed and volume)

When my car was flooded about 4 liters of water got into the engine. I know this as I measured what was initially drained. The first 4 liters were water which being heavier than oil sank to the bottom of the oil pan. That means the OLS was sitting in water for 3 months. I've come to learn that although a sensor does not put out an error code it may be putting out false but plausible values. I think this sensor was putting out lower than actual oil temperatures.

Anyway, picked up a new OLS at Myrtle Beach BMW and just finished installing it. As I'm sitting here typing the car has been idling for 30 mins with the AC on full and the temps have ranged from 83C to a high of 87C - gonna go take it out for a freeway test. I notice now even the aux fan is spinning faster. Ambient temp today in Myrtle is 90F.

Anyone needs an e90 (07 328i 6M) new rad and wp and lower rad hose and wants it cheap send me a PM.

The E93 is the wife's daily driver, so I do not get my hands on it often. With 22k miles on it, has not needed much at this point as well.

But I have always wondered why the car has a prominent oil temperature gauge and no coolant temperature gauge. Not sure if all E9x series are this way, her car is a 2013 and has the oil temp but on coolant temp gauge.

Anyway, this does make some sense that the oil temp sensor may have been under reporting??

In case you do not have this handy, here is the Coolant Temp graph I ran a while back with Ambient temps at around 86F.

For what ever reason, it does not appear these cars stay at a really stable temperature, at least this is the data I have for my car.

Maybe it should be more stable, who knows, it would be nice to compare to your data. My car is a 2013 current with 22k miles and everything except brakes, brake fluid, tires, battery, wiper blades, oil and filter are original.

James,

Swapped out the Oil Level Sender unit this morning with one I picked up at MB BMW. It's like Night and day - I'm very happy even though I now have pretty much an entire spare cooling system. Although this sensor provided no errors it was malfunctioning. I believe it was reporting lower than actual oil temps.

It is 96F outside today. I just drove the car around Myrtle Beach for about 3 hours - on and off the freeway, in heavy stop n go (Hwy 501) - the temp never went past 96C (all this time with AC on full) it seemed to want to stay at 93C.

When it went up to 96C that was on the freeway at 80mph - This engine (N52) is supposed to have 4 modes - the "Eco" mode raises the temp to increase fuel economy at highway speeds - I think that is why it went up to 96C.

This is a far cry from the 107C and the peak 112C that I saw before changing the Oil Level Sensor unit. I was about to swap in a new rad and another WP. I'll be dammed - wish this was better documented.

Your car is overheating - check the oil level sensor??????? Not cheap either - with BMW discount still $163 but that's $30 cheaper than FCP or eBay.

Does your car have an Oil Temp gauge in the dash??

If you look at my graph, it appears the engine temps to rise on the highway, although I was running around and stopping a lot, would like to see what happens on a longer cruise in my E93.

Who would have thought E46fanatics would have super relevant info for my E70? I have an N52 in that car and it has similar temperature ranges, as noted by my OBDII dongle. I thought that it was just normal, based on a lengthy BMW PDF I read, suggesting (as North mentioned) that the WP/Therm change flow rates to accomodate different engine performance levels defined by the DME - economy, performance, etc. I've also found my rad fan reluctant to turn on at times. Perhaps my oil level sensor is in need of replacement - I'll have to investigate further.

As many of the knowledgeable Fanatics move up the BWM food chain, I think they will bring a lot good experience and understanding to the newer models.

While there are other forums for the newer models, I have been a bit surprised with the true lack of automotive experience, ability and knowledge some of the other forums are missing. While there are some experienced and knowledgeable members, their focus is often not hard core repair, more about upgrades, updates and adding options that were not included with the original vehicle build.

Part of it is because some of the newer models do not have enough age or mileage for the DIY'ers to dive deep into. My E93 only has 22k miles is still under the Bumper to Bumper Warranty and has CPO coverage as well, so I will not likely be diving deep into this for a few more years.

As a fellow X5 owner I'm sure you've noticed - it's a wasteland out there. Very, very little info on the forums. Also a bummer (for an amateur like me) that there's no Bentley manual available. They're not infallible, but they sure are helpful.

I am around the X5 Forums a bit, but not heavily. Also so many X5 chassis and not as much hard core support.

Maybe this will change as these models age a bit??

Even the Toyota/Lexus and other Forums are pretty dead.

I recently did a ECU component repair on I think it was a 1994 Lexus ES300 and there was some info, but not much, but I at least posted what I found and did to repair the ECU so others might find help if they still have their 1994 Lexus running!

Hell I was even screwing around with a Cadillac Alante not long ago, I run into some crazy stuff from time to time.
