Am scris o aplicație care citește mașina prin mufa OBD2, după ce Volkswagen a închis We Connect

Mă numesc Davide, sunt din Italia și lucrez singur la aplicația asta.

Am început-o pentru mine. Volkswagen a oprit We Connect și am rămas fără nimic care să îmi arate drumurile și consumul real. Mașina are datele înăuntru, în calculatorul de bord, și cu un adaptor OBD2 ieftin, unul ELM327 pe Bluetooth, telefonul le poate citi.

Partea tehnică, pentru cine se uită la ea. Totul rulează pe telefon. Nu există cont, nu există server, nimic nu pleacă din aplicație. Se plătește o singură dată, fără abonament.

Ce m-a costat cel mai mult timp nu a fost citirea datelor, ci faptul că fiecare mașină răspunde altfel la aceleași întrebări standard. Uneori răspunde altceva, alteori nu răspunde deloc, și atunci nu ai ce inventa.

Un exemplu concret. Pe grupul Volkswagen se citesc gramele de funingine din filtrul de particule. Pe alte mărci se vede doar când pornește regenerarea, și numai dacă mașina dă temperatura. Pe unele nu se vede nimic. Nu promit mai mult decât scoate mașina.

Este pe Android și pe iPhone. Adaptoarele proprietare, cele care vorbesc doar cu aplicația mărcii lor, nu merg.

Există o probă gratuită de 7 zile sau 15 drumuri, aplicația întreagă, fără card.

528i Xdrive won’t go into gear

Going to fully explain what happened so there’s no confusion. Listening to music with car off, get the battery light. I start the car wait like 10 minutes, go to pull out and battery dies. Get it started with a jump pack and I drive for 30 minutes, then I notice I lost transmission power, went into neutral fail safe I put it in drive and reverse and the manual select all acted as neutral. Used the manual override and got it home.

The next day got a new battery and registered it with the car. I went to follow the full process located the fill hole and it dumped fluid out, didn’t stink just dark no metal shavings. Got it to temp and checked again and more fluid came out. Car was level all around. After that happened I used a better tool and found that the transmission is in first gear which would explain why it’s dumping the fluid even though it’s low.

TLDR transmission is in first gear while the EGS is in park. I try to put it in drive or reverse and it goes straight back to park. I’m hoping it’s not the bridge seal or that fun stuff.

I have another transmission I can throw in I just want more opinions before I do that and it still not work.

Codes came up for ratio clutch an and d, and low and voltage at the transmission sensors.

Auto start stop on BMW - do you think it causes more parts to wear faster?

I just read this washington post article where it discusses the politics of auto start stop. Im not interested in that part of the article but saw that Kelly Blue book claims that newer auto technology can handle the wear from auto start/stop technology. I have a 2022 G30 where I cant turn the feature off, unless Im in full time sport mode, and just replaced my starter at 55k miles. Apparently this is pretty common with my G30 where replacing starters this early in a car's lifespan has never been my typical experience. Do you guys think the auto start/stop contributes to more wear/tear or do you think Kelly Blue book is right? Despite changing my starter, I dont mind the start/stop on my G30 as I do think BMW did it well, but I do wish I could turn it off without being in sport mode. I also had to pay ~$1200 to have my starter replaced which I wasn't very happy about. Not sure if this is a common part to go bad this early on BMWs though simply because of the part itself versus it being used for auto start/stop. It was ~$1200 to have my starter replaced....not sure I would trade 10% in gas efficiency for dealing with that again (if the starter failed because of auto start/stop).

F31 is dead

BMW F31, the battery terminal was disconnected, after which the car went completely dead. Voltage is reaching the engine bay and the modules, and the fuses are intact. Nothing works on the car—no central locking, hazard lights, etc. However, pressing the trip meter button does make the mileage appear on the display.

What happened to this steering wheel?

Not sure this is the right sub, if not I’ll delete this. Just got this 650i. I knew the wheel looked like this when I bought it and factored a new steering wheel into the price, I’m curious to know what happened to it. The leather feels like when you pick up an old bat and the grip is rough, and the white plastic portion looks like the prior owner’s dog used it as a chew toy. I have 2 other M steering wheels and none of them look like this and neither do my other 2 non-Ms obviously.

Problems when installing e91 transmission

Hello, my friend has bmw e91 2005 with m47 and zf6hp19 automatic transmission. We took off the transmission to replace torque converter and now we are having hard time when we are trying to get it back together.
Main issue is when we are trying to attach tc back to flexplate. We cant get the bolts on without tc coming off from pump.

First photo is when we were taking transmission off.

Engine isn’t in straight line now and even when we get it straight with the transmission we cant put the bolts on from the gap beetween engine and transmission.

AI suggested that we take starter off and try that way but i thought i should ask here if someone knows any tricks.

All help is needed:)

N55 - Excessive Oil Consumption

Hi All,

A few months ago I bought my first BMW after wanting one for years. It’s an E82 135i (N55 DCT) coupe in Le Mans blue, cream interior, sunroof, the works. However, it was sat in a garage for 5 years prior to me purchasing it (it’s done about 200 miles in the entire 5 years).

Within 4 months of ownership, I’ve already dropped £3k on maintenance and repairs:

- Oil Filter Housing Replacement (incl. gasket)
- Valve Cover Replacement (incl. gasket & PCV/Breather System)
- Crank Seal Replacement (I unfortunately found out that it had chewed up a serpentine belt at some point in the past, so oil was leaking through the front crank seal as well)
- Crank Seal Guard Installation
- Turbo Inlet Pipe Replacement
- Serpentine Belt & Pulley Replacement
- Radiator Hose Replacement
- Oil & Filter Service (Replacement)
- Mechanical Oil Pressure Test (came back perfectly) - the sensors show electrical short codes so I wanted to be sure everything was okay after the belt ingestion I didn’t know about.
- Removal of Stage 1 map and return to Stock map.
- a few other minor things (third brake light, speakers weren’t connected properly etc)

The Oil Pan gasket had also just been replaced by the previous owner.

I’ve noticed since actually being able to drive it, for more than a day between garage visits, that it’s consuming an excessive amount of oil. I’ve consumed about 1/2 litre in just over 300 miles. That’s a mix of driving it from the Midlands back to London, commuting to work (from South London to Slough) twice a week, along with some spirited driving (when I can get out of London lol). Even though I’ve heard N55’s love burning oil, I know for a fact this is too excessive to be considered ‘normal’.

The car runs and drives perfectly, however sometimes I can smell burning oil in the cabin, and it’s more noticeable when you park up and stand by the bonnet after just finishing a drive.

I’ve read mixed things on the forums, ranging from the valve cover replacement not being done properly (meaning oil is dripping into the exhaust), all the way to the valve stem seals are finished and the engine needs stripping (which considering my current repair expenditure, would be a tough pill to swallow).

The car has no visible leaks underneath anymore, I’ve had cardboard under there for the last week and not a single drop has appeared. There were a couple when I first took it back from the garage, which I’m pretty sure was brake cleaner after cleaning the ridiculous amount of oil that was all over the place (according to the garage).

All of the work has been carried out by BMW/German car specialists. The garage that worked on it most recently (and did the valve cover) was a highly reputable BMW specialist that seemed super honest and talked me through the whole process.

Any advice/help on how to tackle this would be much appreciated. How much of an (albeit very pretty) lemon have I bought?

p.s. I knew old BMW ownership wasn’t for the weak, but Jesus Christ… this has been a trial by fire to say the least.

Increased battery drain while stopped

I have a 2019 M240i with 95k miles. I bought this car a month ago. Today in the morning I got a message saying increased battery drain while stopped. It also says vehicle battery charge low. I checked codes in bimmerlink and also checked the state of charge and it's at 16% right now. I checked the state of charge 2 days ago it was at 78% everything was all fine until this morning. I also checked the voltage today while idling it was around 14.3v then it went to 15.3 then back down. The battery is only 1 year old. Could it be a bad alternator?

F22 M235i replacing suspension

I have m adaptive shocks but i find the ride to be kind of shit plus I cant tell the difference between comfort and sport. I believe there are two possible reasons for this, first the previous owner has put lowering springs on it, I dont know what kind but it is lower, and thats ruined the geometry or 2nd the shocks are just cooked after 12 years 150k kms, i think they are starting to leak as well.

Now do I sacrifice my first born and get bilstein adaptive suspension, I am worried the lowering springs will ruin any benefit to those, or do I get like that Birds B2 suspension kit thats non-adaptive and half the price but does have new springs?

2018 F30/F31 330i B46/8 - Experience with iDrive and BimmerCode.

Hey all. Just picked up a 2018 F31 and have been fixing lots of small issues and maintenance items. Finally got everything dialed and she’s running great, but the iDrive/media is doing weird things (CarPlay disconnects right away and the Bluetooth audio glitches).

I brought it to the stealership to update the iDrive software, but they told me the car has several software options that are currently installed that weren’t initially purchased with the vehicle, and updating the software might brick the system.

I assume PO used BimmerCode or something similar to add these options. I also see on BimmerCode’s website that the system/software has to be stock/OEM in order to use their app.

That being said, am I safe to update my software at the dealer to revert everything back to stock? No chance of anything getting bricked? Can I use BimmerCode to revert these changes myself? Any help is greatly appreciated!

Can anyone identify this system S54 (M3)

Its at the top right side of the engine bay. Between the firewall and strut. The sensor here was loose / unplugged.

Wondering as I've had a misfire on cylinder 2, mass airflow circuit A low and for some reason my battery drained to 9v overnight!!
