My Ride: 2005 330i ZHP
EWS Manipultion Protection Code

Greetings to all. New to the site and would greatly appreciate some input from the veterans. I have a 2005 330I ZHP with 70,000 miles. Recently I've been having random starting issues with the car. Not cold starts, but rather re-starts after short trips. The engine cranks fine but takes several attempts to start. The only code that has shown up is a EWS Manipulation Protection code. I've replaced the ignition coils, fuel filter, spark plugs and the intake boot. The problem is very random but extremely frustrating. Don't like others seeing my BMW struggle to start! Any help or suggestions would be appreciated. Have two keys and the issue happens with both keys. This morning, I started the car and it had a very rough idle and threw a multiple cylinder misfire code. I shut it off and started it with a different key and it ran fine with no codes. Drove it about 8 miles to post office and when I came out of the post office it took about 4 times cranking to start the car. No check engine light though. Any other suggestions.

Thanks for the reply. I've got two keys and it happens with both of them. I read that it may be possible that the EWS and DME may need aligned but when I called the "stealership" they indicated that they would have to do a complete diagnostics check. I only have one dealership in my state which stinks!

The EWS is a theft prevention black box under the dash. It's connected to a wire coil around the ignition switch in the steering column that senses the key in the ignition. Further it's matched against the DME in the car. Once the EWS is matched to the DME it can only be used with that DME (at least from BMW's perspective).

While I'm not familiar with that code you're receiving I am aware that using BMW programming tools you can update the software in the DME, whitch would correct any possible bugs in software, and you can recalibrate the EWS module with the DME. It's also called an EWS/DME realignment.

I would say your problem is either with EWS/DME calibration or there is a wiring fault between the coil that reads your key and the EWS unit.

Is it possible for me to do the "realignment" myself or would the tools to perform this only be available to dealers? Seems if there were a calibration problem, it wouldn't start at all rather than these random issues?? The code is 2737 (using the fault code reader sold by Bavarian Auto) "EWS 3.3 Manipulation Protection".

One of the things the EWS does if the key is not right or incorrectly read is it disables the starter so you would not be able to crank. Since cranking is not one of your problems I think you are wasting your time investigating the EWS/DME. Clear the error log and check again periodically for fresh codes.

Mine was a physical problem rather than electronic. Short starts worked fine; long starts worked fine. But intermediate starts at about the one hour later time frame took a long time to crank and catch. And the key is, mine smelled like gasoline when I started up after cranking for a while.
I figured it was leaky injectors that flooded the engine short term, so I replaced all my injectors. Problem solved.

Many thanks to all who responded. This forum is great. I'll continue to monitor to see if any other codes pop up. It's been going on for over 6 months off and on. Just worried one of these times it might not start at all.

If synchronizing is what you're looking for, inpa can do it, although I doubt. That's your issue. It's simple as this, as far as my experience with the ews having successfully coded a transponder to my own ews. It has no thing to do with it. When I had issues with my car where it would crank but not turnover over, it gave me ews errors too. I know it's been over 7 months since you commented but you might want to look at your fuel situation. Fuel filter or pump. Mine was the fuel pump.

Might as well give all the options so people can know what controls they can program and plan in advance to customize just the way they want.

Probably not the filter. More like the pump
