Jontelito

Hello,

I need som help, it get warnings about parkingbrake and esc fault and the car don't start.

Jontelito

A couple of days ago, my car started to give me error codes on startup / ignition on, it complains in the display on parking brake malfunction and stabilisation control esc fault, and when I search with the OBDeleven I get many error codes almost all pointing to ECM, so I guess somewhere there lures my problem..

When the error occurs and all codes are given, the car does not start, I can delete all the error codes and after switching off and on ignition, then the car starts and everything works properly.

What is done?
Battery checked, 12.8V standby, 14.4V when driving, Charged to 13.00V, pending between 9-10V at startup.
Error codes cleared several times, can go anywhere between 1-4 starts between times the car gives error codes.
Cleaned MAF sensor and Intake
Cleaned connectors at ECU side
Cleaned connectors at parking brake module

Anyone who can check the error codes below and maybe give me a direction to go on next?

Here is a clip on the messenges I get:

ESC+parking brake lights is a general "something is wrong with the car". I had the same thing this morning, because I forgot to plug the MAF cable back in after changing the air filter. Seems it's too hard for the car to just say "MAF disconnected".

OBD11 doesn't provide more detail? There's usually a subcode with what's actually wrong, as well as a freeze frame, when I get errors in VCDS. Such as:

02283 - Video Connection to Output [End Unit]
011 - Open Circuit - Intermittent
Freeze Frame:
Fault Status: 00101011
Fault Priority: 3
Fault Frequency: 1
Reset counter: 84
Mileage: 244090 km
Time Indication: 0
Date: 2017.07.25
Time: 09:54:42

Freeze Frame:
Term 15 On
Reverse ON
Count: 4

Maybe a loose connector block somewhere. I have the issue with short to ground for the keyless antenna in the back left door. But the wire is not direct from the antenna to the comfort control module. They both connect at a block in the bottom of the left B pillar.

The OBD11, says:

Trouble codes:
01314 - Engine control module (ECM) No signal/communication
Intermittent

Then you need to search for the code and then you get:

01314 - Engine Control Module: No Communications
Possible Causes
CAN-Databus Wiring/Connectors from/to Engine Control Module faulty
Fault(s) stored in Engine Control Module
Engine Control Module recently flashed or re-mapped
Possible Solutions
Check CAN-Databus Wiring/Connectors from/to Engine Control Module
Check Measuring Value Blocks (MVB)
Usually Measuring Value Blocks (MVB) 125+ show the current Communication Status

Jontelito

In my Lefthand drive Audi it was in the fusebox in front of the driver seat, located in the "fishbowl" in the engine bay.. fishbowl = the area between windscreen and motor.
