Damage code

Cause

Remedy

 

 

Station change without 
obvious cause. 

 Some radio stations 

which had originally 
transmitted regional 
identification have been 
transmitting the RDS 
signals without regional 
identification for some 
time. 
Without regional 
identification it is no 
longer possible to 
separate stations with the 
same station name which 
transmit different 
programs.

1 Point out the facts to 
the customer. 

 Do not replace any 

devices, state of the art 
engineering.

Damage code

Cause

Remedy

 

 

Under unfavorable 
reception conditions in 
FM-RDS mode, the radio 
may frequently switch to 
alternative frequencies of 
one and the same radio 
station.

 Due to the equipment 

and antenna design there 
is no remedy available.

 

 

 

During switchover, 
reception may be 
interrupted for a brief 
period.

Do not replace any radios 
subject to this complaint 
only!

Remedy

 

 

Complaint is caused by 
retrofitting metallized 
window foils.

 When installing 

window foils, cut foil 
outside of vehicle to 
avoid damaging the 
antennas and heating 
wires
 

 

 

 Metallized foil: 

AM reception 
reduced approx. 70 
%, among other 
problems search 
stop no longer 
possible  

FM reception 
reduced approx. 10 
% .  

TV reception 
reduced approx. 10 

 Do not use metallized

Cause

Remedy

 

 

Loss of noise filtering 
function of the antenna 
splitter (A2/5) and the 
AM/FM amplifier 
(A2/18) due to poor 
ground connection.

1 Remove AM/FM 
amplifier

AR82.62-P-8347GH

 

 AM radio reception is 

being adversely affected 
by background noise and 
electrical interference, 
resulting in the station 
signal being overridden.

2 Remove antenna 
splitter

AR82.70-P-8953GH

 

The painted surface of the 
vehicle's body, combined 
with the protective 
coating on the mounting 
screws, may not provide 
an adequate ground.

3 Remove paint/E-
coating from vehicle 
body at mounting points 
of antenna splitter and 
AM/FM amplifier

 

 

 

4 Remove protective 
coating on shoulder of 
antenna splitter and 
amplifier mounting 
screws
