BMW Angel Eye Headlight Fault
You don’t need to be a BMW fan in order to recognise the manufacturer’s impeccable design. Just take a look at the BMW 4 series. In addition to thrilling fans and frustrating classical design pundits alike, the second-generation models feature a unique BMW design language.
Aside from the new kidney grille, some things haven’t changed much with the model. In the new model, BMW has carried over its Angel Eye accent lighting. It’s pretty much BMW’s nighttime signature.
Anyone who has seen a BMW at night knows how iconic those accent lights are. In the same way as the kidney grille, they distinguish a BMW from other cars.
It’s one of those unique features that should be cherished and celebrated – especially since it keeps you safe on the road.
So if anything goes wrong with these Angel Eye lights, it needs to be resolved immediately.
One of our recent clients with a 2015 BMW 420 understood the importance of the lights, so they brought their BMW to Garden City Garage immediately for a quality fix after developing a problem.
There was a problem with the right-side Angel Eye headlight on the client’s vehicle, which resulted in it not working. While listening to the customer’s comments, our lead BMW technician began to paint a picture in their mind of how to fix the problem.
Our technician put the client at ease, and assured them that their issue would be resolved in a timely manner. After speaking to our technician, the client handed over the keys, and put their trust in our BMW specialists at Garden City Garage.
Our technician began by inspecting the vehicle visually. So read on to find out what happened next….

The Issues We Found
Our lead BMW technician inspected the lights and found out that the right-side light was faulty. Furthermore, neither the opening or closing of the switch worked.
Believing that the headlight driver module might be the problem, the client had already had that replaced at another garage. But that didn’t help. The issue remained – there was still a problem with the accent light.
In order to understand the issue, our technician had to inspect the problem further. As a result, our technician decided to scan the entire vehicle – finding any fault codes can usually give a good understanding of where the problem lies.
There were some error codes found by our BMW technician pointing toward the right-hand headlight and a fault with the LED unit.
Therefore, our technician had to initiate the Garden City Garage in-depth diagnostic procedure and find the root cause.
The Diagnostic Procedure
At Garden City Garage, all technicians follow the 15-step diagnostic process. Following the 15 steps ensures we don’t miss anything during the diagnosis, and enables our specialists to identify the problem and apply a solution in a timely manner.
Our BMW technician examined the bulb, its sockets, ground wire, and connector wiring but found nothing unusual. Considering the condition of the components, the Angel Eye light should have worked. However, that wasn’t the case, so our technician continued to look for another solution.
Our technician began to recall all the headlight repairs they had performed in the past to try and figure things out. Furthermore, our technician compared the problem at hand with similar issues using AOS online data resources.
Based on our thorough investigation and testing, the LED module was faulty, and it could be updated or replaced to finally solve the problem.
After determining the cause of the problem, our BMW was able to focus on fixing the problem reliably and efficiently.
Fixing the Problem
Our BMW specialist used the ITSA software and AOS to find out what the problem was behind the 420. While the rest of the unit was in decent condition, the LED module needed to be replaced.
Our expert technician performed the repair and checked the Angel Eye light to ensure that the fix was complete. As expected, the light was now working.
Afterwards, the car was checked again for fault codes and found none relevant to the repair. Now that everything was in order, it was time to return the car to the client.
Not only did our technician perform their job efficiently, they also did so as cost-effectively as possible, saving money and time for our client.
In Summary
