Hello everyone,

I have had three SteuergerÀt failures on my Sharan in the last 12 months.
It all started with the "Radio"

Address 5F: Information Selection. I (J794) Label file:| 5G0-035-MIB-STD2.clb
Part Number SW: 5C0 035 680 B HW: 5C0 035 680 B

This week, the all-wheel drive control unit broke down:
Address 22: Allrad (J492) Label file: * DRV\0CQ-907-554.clb
Part Number SW: 0AY 907 554 J HW: 0CQ 525 130

To top it all off, there is also:
Address 16: Steering Wheel Electronics (J527) Label file:| DRV\5K0-953-569.clb
Part Number SW: 5K0 953 501 ED HW: 5K0 953 569 AN
Part: STEERING MODULE 016 0180
Revision: FF010042 Serial Number: 20151016101444
Encoding: 3102C40008
Operating Number: WSC 00020 999 00000
ASAM Dataset: EV_VW360SteerWheelUDS A03004
ROD: EV_VW360SteerWheelUDS.rod
VCID: 70EA7552ABCEB109B5-8025

Steering wheel multifunction control:
Subsystem 1 - Part Number SW: 6C0 959 442 B HW: 6C0 959 442 B Label file: DRV\3C8-959-537.CLB
Part Number: E221__MFL-TAT H04 0019
Serial Number: 2521505130500497AF2B
Encoding: 2C0000

2 error codes found:
448019 - Multifunction Buttons on Steering Wheel, Left
B114B 96 [009] - Internal Component Error
Confirmed - Verified since last deletion
Environmental Conditions:
Error Status: 00000001
Error Priority: 3
Frequency of Errors: 1
Lost Count: 117
Mileage: 99431 km
Date: 2022.05.19
Time: 20:57:21

448275 - Multifunction buttons on the steering wheel, right-hand side
B114C 96 [009] - Internal Component Error
Confirmed - Verified since last deletion
Environmental Conditions:
Error Status: 00000001
Error Priority: 3
Frequency of Errors: 1
Lost Count: 117
Mileage: 99431 km
Date: 2022.05.19
Time: 20:57:21

The final errors cannot be deleted, so they remain in the trash.

Now, regarding my question, could there be a deeper issue here? Power supply? This is 14.7V when the engine is running?
Does anyone here experience their engine control units (ECUs) failing?

Hi Christian,

kenne ich nicht. Die Frage ist, ist die Ursache Überspannung im Bordnetz oder ein Wasser/Feuchtigkeitsproblem?
Letzteres sollte sich ja relativ leicht feststellen lassen.

Wenn Du ein HEX-NET hast, könntest Du die Bordspannung im Fahrbetrieb relativ einfach loggen.
Oder halt per Laptop.

Denkbar wĂ€ren auch aufgescheuerte Kabel im Baum welche sporadisch KurzschlĂŒsse verursachen und beim Nicht-mehr-Kurzschluß Spannungsspitzen im Bordnetz verursachen.

Auch solltest Du mal nachdenken, ob etwas am Radio geÀndert wurde, die Pinbelegung vom ISO-Stecker ist nicht genormt und es wÀre denkbar, unbeabsichtigt z.B. einen Lautsprecherausgang auf den CAN oder K-Line zu legen...

Viele GrĂŒsse, Rainer
