Title: Missing message from instrument cluster/abs/esp (everything on can-bus) Post by: ddillenger on February 16, 2013, 12:38:36 PM Any idea what could cause this? VCDS scan below. To me it looks like something is preventing communication on the can-bus, but what could it be? All modules are detected, all soft coding is correct. Have verified ground integrity at the modules, battery voltage is good, car runs well.
Not that it isn't clear in the scan, but car is a 2001.5 s4 with esp/abs. ------------------------------------------------------------------------------- Address 01: Engine Labels: 078-907-551-AZA.lbl Part No: 8D0 907 551 M Component: 2.7l V6/5VT G 0002 Coding: 06711 Shop #: WSC 00001 VCID: 3469CA6D04B2FBB8F54 3 Faults Found: 18057 - Powertrain Data Bus P1649 - 35-00 - Missing Message from ABS Controller 17931 - Crash Signal from Airbag Controller P1523 - 35-00 - Implausible Signal 18058 - Powertrain Data Bus P1650 - 35-00 - Missing Message from Instrument Cluster Readiness: 0110 0100 ------------------------------------------------------------------------------- Address 03: ABS Brakes Labels: 8D0-907-389.lbl Part No: 8D0 907 389 E Component: ABS/ESP allrad D36 Coding: 04395 Shop #: WSC 06435 VCID: 356FF7690FC8E2B0C2A 2 Faults Found: 01203 - Electrical Connection between ABS and Instrument Cluster 03-10 - No Signal - Intermittent 18258 - Powertrain Data Bus P1850 - 35-00 - Missing Message from ECU Title: Re: Missing message from instrument cluster/abs/esp (everything on can-bus) Post by: prj on February 16, 2013, 12:56:36 PM Make sure CAN is not short to plus, short to ground, and that the ECU connector is fine.

Title: Re: Missing message from instrument cluster/abs/esp (everything on can-bus) Post by: imolasb5 on February 16, 2013, 08:33:58 PM I have had pretty much these same codes for about 6 months now. I haven't found a resolution yet. It seems that some people see it being caused by a popped fuse, but not my problem.

The large red plug under the ecu was half out. All sorted now. Title: Re: Missing message from instrument cluster/abs/esp (everything on can-bus) Post by: adeyspec on March 06, 2013, 11:49:52 AM shame mine isnt the same issue ??? similar codes though
Title: Re: Missing message from instrument cluster/abs/esp (everything on can-bus) Post by: ddillenger on March 06, 2013, 11:51:57 AM Your issue is the ecu. Methinks it uses a different protocol to communicate between the modules in the car.
