Complaint:

The vehicle cannot be started
The vehicle may start by itself shortly after the startup attempt with a delay, as the relay can be late closing.
and/or
The gear selection is displayed, but no gear is engaged. Gear selection is not possible.
and/or
Rear window wiper inoperative.
and/or
Various fault codes concerning disrupted communication paths are stored and/or the corresponding control units are
not displayed in the quick test. Affected control units include the transmission control unit, electronic ignition lock, driver SAM, engine control unit, Lane Keeping Assist, Distronic.

Cause:

The micro-relays in the fuse and relay boxes (SRB) in the engine compartment or rear compartment may have a malfunction and not close correctly.
Due to this malfunction, there are disruptions to the communication paths and no power supply to various systems.
Only affects relays manufactured by Hella with a Date Code (picture: Assignment of Date Codes) from 2248 to 3159.
If the faulty micro-relay(s) of the problem systems fall(s) within the batch carrying this Date Code, then all the micro-relays in the fuse and relay boxes listed below in the vehicle should be checked and likewise replaced if their Date
Code is between 2248 and 3159.
To read the date code:
First digit: Year of production 2=2012
Digits two through four: Day of production year
Note: The problems may occur only intermittently, so diagnosis of the relays is not always possible and the fault may
not always be reproducible.

Assignment of Date Codes to affected relays

Remedy:

ONLY REPLACE MICRO RELAYS (picture: micro-relay) MADE BY HELLA WITHIN THE RELEVANT DATE CODE
RANGE 2248 - 3159!
Normal-size relays, e.g. circuit 15 on the driver SAM, must not be replaced!
Perform an initial quick test.
Replace the following micro-relays (PDF attachment) if Date Code is within the batch:
BR246/176/117: Engine compartment fuse and relay box
Relay O, transmission oil auxiliary pump
Relay S, circuit 87C with OM607
Relay P, reserve
BR204/207/212/218/231/172:
Rear fuse and relay box
Relay A, circuit 15
Relay D, fuel pump-circulation pump
Relay E, rear wiper
Relay G, circuit 15R2
Engine compartment fuse and relay box
Relay R, circuit 87F
HybrideBay logo fuse and relay box
Relay S, transmission cooling coolant circulation pump
Relay U, power electronics coolant circulation pump
The replacement relays may be manufactured by Tyco instead of Hella, and must be ordered according to the quantities and part numbers in the vehicle.
The removed relays must be sent back through the usual warranty channels accompanied by the initial quick test report.
The relay responsible for the problem must be clearly marked (using a waterproof marker on the relay itself) with the
designation of the slot (e.g. P; O; etc.) and marked as DEFECTIVE. The other replaced relays must likewise be marked with the designation of the corresponding slot.
