Hi everyone,

Got a W176 A Class 2014 and hoping someone can help me. Per the title, the front passenger window, lock, wing mirror have all stopped working. The fault points to the door module but I have replaced that but no difference.

The problem happened previously for a few days and then disappeared. However, it's back now and has not gone away. OBD check shows door module wasn't communicating but I like I said, have replaced that module. All fuses are ok, the wiring loom through the door appears ok and the door module is getting power.

Does anyone have any ideas? Any help appreciated.

Thanks in advance.
 
Broken wires can be difficult to see.
Also, was the replacement module new or used? Either way it may need coding?
 
Definitely, any suggestions where else to look?
It was a replacement module from eBay. How would I code it? Apologies if that's a daft question.

If it needs coding then the short answer is that you cannot.

If it needs coding then only a Mercedes dealer or MB specialist with Star /Xentry (MB specific diagnostic computer) can do this.
 
Oh right. Thanks for the heads up, I'll look into seeing what I can do/find out. Thought it'd be a quick, cheap fix, maybe not as cheap as I thought.
