Low Beam Operation With the lighting switch in 2ND position, the BCM receives input requesting the headlamps to illuminate. This input is communicated to the IPDM E/R across the CAN communication lines. The CPU of the IPDM E/R controls the headlamp low relay coil. When energized, this relay directs power ? through 15A fuse (No. 36, located in the IPDM E/R) ? through IPDM E/R terminal 20 ? to headlamp RH terminal 1, and ? through 15A fuse (No. 45, located in the IPDM E/R) ? through IPDM E/R terminal 30 ? to headlamp LH terminal 1. Ground is supplied ? to headlamp RH terminal 2 ? to headlamp LH terminal 2 ? through grounds E15 and E24. With power and ground supplied, low beam headlamps illuminate.

System Description EKS008LH Control of the headlamp system operation is dependent upon the position of the combination switch (lighting switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives input requesting the headlamps (and tail lamps) to illuminate. This input is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The CPU (central processing unit) of the IPDM E/R controls the headlamp high and headlamp low relay coils. When energized, these relays direct power to the respective headlamps, which then illuminate. OUTLINE Power is supplied at all times ? to headlamp high relay, located in the IPDM E/R, and ? to headlamp low relay, located in the IPDM E/R, and ? through 50A fusible link (letter f , located in the fuse and fusible link box) ? to BCM terminal 70. With the ignition switch in the ON or START position, power is supplied ? through 10A fuse [No. 1, located in the fuse block (J/B)] ? to BCM terminal 38. With the ignition switch in the ACC or ON position, power is supplied ? through 10A fuse [No. 6, located in the fuse block (J/B)] ? to BCM terminal 11. Ground is supplied

check fuses in box near coolant reservoir.fuses should be marked on box cover.hi/lo and left and right fused individually for atotal of four fuses for headlamps.

poss a burned headlamp does it work on high beem and is the fuse for the headlamp blown?

Check the fuse no.# 20 - F20 (15A) = RH headlamp - low beam & the fuse no.# 21 - F21 (15A) = LH headlamp - low beam, located in the fuse box / relay plate fascia 1, placed on the driver's lateral side of the dashboard, door open. See pictures below:




Please do rate my response. Thanks!

It can be one of the following;

The headlamp relays located under the hood and clearly marked(there is one for the right headlamp and one for the left headlamp - swap them and see if the problem goes to the other side. If not - then it is the dimmer switch itself.

Take Care.

each head light has a seperate fuse should be mounted under hood in fuse n relay box

There should be a main fuse box under the hood. The headlights have a main fuse for each side. There should be one for the left and right headlamp. Check the fuse for the r/f headlamp. If it is blown, then that is the cause for the headlamp not to work. Replace with a new fuse and it should be good to go. If not, check the bulb itself.

For Audi A4 the fuse box is located on the left side of dashboard behind a plastic cover (for left hand steering wheel vehicle). On inner face of the plastic cover you will find the fuse diagram.
First fuse on first row from left upper corner is Fuse Nr.20 = F20 (15A) - RH headlamp low beam, headlamp adjustment.
First fuse on second row from left upper corner is Fuse Nr.21 = F21 (15A) - LH headlamp low beam, headlamp adjustment.
