mine is running great, havent updated the thread because of busy schedule and exams, no electrical issues at all, though AC may be suffering from potential problem on a recent motorway journey lahore to islamabad and back last week in 40C whether the AC doesnt seem to cool well at slow speeds, i had it on STAR to see if there were any issues but the ac module and all other modules came code free no errors, even the tech operating the star machine was surprised saying he has never seen any Mercedes car have less than minimum of 6-8 errors any day. i have ordered set of Ac gauges and vacuum pump and refrigerant weighing machine myself, will look into this issue later and also have checked from shahnawaz for avaiblility of brand new compressor and condensor if needed which they confirmed they can get for me in 3 weeks and set aside the budget, though i am hoping its just incorrect weight charge or potential issues with compressor or expansion valve which i would be able to diagnose using the manifold guages. blower was fine and good air flow through all vents and all the flaps and actuators work properly and no noise(pretty rare on an old w203).
apart from this its running strong, it gave better fuel consumption on motorway than my 2010 altis while traveling at higher than normal speeds than altis too, i have a lot to update including many upgrades like TPMS, in car entertainment, and MB accessories but that has to wait. otherwise like yours once you maintain these cars well and they are solid examples to begin with then they are exceptionally reliable.
in the same two year time span my 2015 gli failed to start and left me stranded till I figured out the people from the dealerships had forgotten to tighten the battery clamps. my 2011 gli developed a p2121 error code issue and check engine light though it was later resolved, and the power mirrors motors on 2006 altis gave up and had to be replaced. so overall Mercedes has been the most reliable barring the maintenance items such as suspension fluids etc that i had done overtime.
