Cleared codes with OBD scanner, now car won't start. HELP!!!

[TropicalM3]

Now that you have INPA, you can clear any codes now without worrying. For me INPA is my go to scanner for my M3

[Mikehest22]

It was an issue with an older version on the Foxwell scanner. I had to realign the EWS. I ordered a cable and installed INPA, worked like a charm. Thanks all.

[Mikehest22]

All good advice. I am going to go the INPA route and get that downloaded and set up.

Sure you can do that too. It requires modifying the software in your DME though.

or using a (paid) tool:

Resync is probably the simplest option.

Yes ews is nice to have especially if you're not parked in a garage all the time. It's easy to beat the tumblers even with the Lazer cut. It's getting past the computer that's tricky to thieves. You remove that and you're making it that much easier to steal. Plus you're not 100% sure that's your issue. Try a resync like stated or get it professionally diagged. If you're not familiar with cars you can cause more problems trying to delete the ews, and then it's just more of a headache for the actual mechanic

Yeah unaligned EWS will do that. Start up normally and then immediately die. Like less than a second between letting go of the key and engine dying.

This is for an x5, but the process is probably very similar for the e46: https://xoutpost.com/bmw-sav-forums/...code-4a63.html

If you can't get the scanner to work, INPA or DIS can do the realign.

I saw something on Youtube about an EWS delete, any experience with that?

[Mikehest22]

Did you happen to perform any service other than simply reading codes? Did you unplug any sensors by any chance?

Perhaps if you did an oil change you forgot to plug the TPS sensor back in near the the oil filter housing.

No other service.

Not sure if that scan tool can do it, INPA does. What exactly is the car doing? I'm only guessing here.

It turns over like it's going to start then dies immediately

The EWS system is the cars security system, where the key has to transmit a code to the car for it to start. Maybe that is out of sync.

Is this something that can be done with a scan tool?

What does this mean?

EWS? May need to re-align.
