E46 320ci 2001 - no communication - no start

After my e46 started flashing the battery light.
I replaced the battery. After the first start it died.
And smelled a pertrol smell.

After this happend the car did crank but would not start.

Ive checked the fuses under the hood and replaced the DME relay. Still nothing...
My bluethooth OBDII would not connect (anymore) or start collecting any info.

When the key is in position 1 the temp gauge goed straight in red and wont drop down.
Also the handbrake light is on, and the handbrake is pulled.

The car is at the dealership at the moment and i just called with them. They think the 'brain' is dead.

And tips are appriciated

320Ci coupe pre-fl 2001

The battery is the likely culprit. These cars are rolling computers so when the battery starts going bad the car will exhibit so weird symptoms.

Could be a fried brain as they said. The OBD not responding is a good supporting indicator.

Check for water / corrosion near the DME itself.

Also inspect the main engine wire harness.

Check fuses, especially the 5 fuses inside the DME box.

Get that car back from the dealer ASAP and get it home for some cheap and simple diagnosis. You've got electrical problems.
1. Measure the battery voltage.
2. Scan all modules with BMW Scanner 1.4.
3. Report these results here for further instructions.

1. Ive checked the battery voltage the friday before i changed the battery. When motor is off battery was 12.+V and when running stationary 14.+V

2. The bmw scanner 1.4 is a scan tool for the odb plug under the hood?? As i could not make any connection with the OBDII under the dashboard (driver side)

If your car has the round connector under the hood, then get the round-to-OBD adaptor and use that.

Euro cars got OBD support a little later than USA cars, so research if yours has it or not. It should work.

For the under dash OBDII port to work, the cap with jumpers needs to be installed on the 20 pin round DLC connector. The team Guage pegging is somewhat common, but I have never had anyone state what the problem was or how it was fixed.

I agree an electrical problem, did the DME die or become corrupt or is there a bad ground?

Maybe disconnect the battery terminals and touch them together for 30 seconds.

OP's car is Euro spec, so I'm not sure if his OBD port is wired completely or not? If he has the under hood connector he should use that I assume.

EOBD or Europen OBD was not phased in as early as North America (1996). But if the OP car has a 16 pin EOBD/OBDII port under the dash, the car supports at least the DME and possibly the EGS via the under dash connector, however, the 20 pin round DLC cover with the jumpers needs to be installed for the 16 pin under dash connector to function.

One thing that the earlier EOBD cars would not have is the SES/CEL/MIL turn in when there were fault codes. You would need to check for fault codes. Additionally, depending on when the EOBD was implemented in the specific non North American market, there may or may not be standard Pxxxx formate EOBD/OBDII fault codes.

I assume the OP had his Bluetooth OBD App connected at one time due to this statement - "My bluethooth OBDII would not connect (anymore) or start collecting any info." I just wanted to make sure the OP was aware that the 20 pin round DLC connector cap needs to be installed in order for the under dash 16 pin connector to work.

This to me, indicates that at one point the OP had a Bluetooth OBDII App connecting and communicating with the car.

Now the one problem is the under dash connection will not communicate with all vehicle modules, so for anything other than DME and EGS, then the under hood 20 pin round DLC connector will need to be used, likely with a 20 pin round DLC to 16 pin OBDII adapter cable.

Called with the stealer and they concluded that the Main Dme is working properly.. They switched it into another e46 and it worked?? #fml

What could it be?
Could it be the 02 sensor error? Ive read that one before my car stopped working.. I dont think it jas anything to do with the starting issue.

What relais / relays are worth checking?? All of them??

Still cant get things right in my head... Why would the asc and handbrake light come up? And the temp? Temp sensor??? Or am i missing something...

These issues are characteristic of an electrical / coding failure.
If the EWS (security system) is not synched up to the DME, it can do this.

At least when I had a DME update that failed, the car would still crank, but would not start (EWS not synchronized).

How can a ews be synced when obd is not functioning??

Is bypassing the ews a option? Is it hard??

Cant the new battery be the bad guy? Its a higher ampere than the ome before? Any chance? I know 12v is 12v. Just wanna cut out all options..

And how about the allignment between EWS and DME??
Stealer told me they checked the connections between it and 2 of them where dead??

Also can the key be bad? Got another spare one at home and also 2 plastic kinds??? Would it be worth bringing the keys to the stealer??

Antenna rings ive read some about also?? Maybe?
