Electric Motor Design

I've been having a nightmare with my 2017 VW Golf recently and could really use some advice. A couple of weeks ago, I noticed a faint burning smell coming from the dashboard area, especially after I'd been driving for a while. At first, I thought it might just be dust burning off the heater, but the smell has gotten a bit stronger and now I'm genuinely worried. I've read that a burning smell can point to a serious problem like overheated wiring, which is definitely not something to ignore, especially with the heat we get here. I took it to a local garage in Mussafah, but they just gave it a quick look and said they couldn't see anything obvious, which didn't exactly fill me with confidence. I really need to find a proper specialist who has the right diagnostic equipment to check the wiring, battery, and alternator properly. A colleague mentioned that he had a similar issue and got it sorted through a mobile service that offers Proficient Electrical Repair By 800Sayara Abu Dhabi, and they were able to trace the problem to a faulty ground connection that was causing the wiring to overheat. I'm just trying to find someone reliable who won't just guess and charge me for unnecessary work. Has anyone here had to deal with a burning smell from their car and found a trustworthy specialist in Abu Dhabi who actually fixed the root cause? I'd really appreciate any recommendations.
