Hello, I'm new here, but from what I've read I'm in the right place to get assistance.
I own a 2011 volkswagen jetta tdi 2.0 sportwagen.
Miles at 140k
New engine, turbo and flywheel installed at 100k.
I get my oil changed every 10k miles as recommended
Timing belt water pump and serp belt were also replaced with engine.

In nov 2023 I took my vehicle to young volkswagen to have the alternator replaced.
To replaced the alternator they chose the method of removing the a.c compressor to have enough space.
Two weeks later my radio started flickering, by Feb 2024 the radio no longer received FM AM Radio channels/signals and had a warning of overheating and shut itself down to protect itself.
By may 2024 my a.c stopped working i took the vehicle back to the dealership for a diagnostic by July 2024 and they said the a.c compressor was not turning on at all and they checked the radio and it had a internal communication error with the antenna.
By aug 2024 the new alternator went out took it in to the dealership again they diagnosed that it was indeed bad now

New alternator was installed in aug 2024 when installing it they found my radiator fan was damaged and the the ground wire harness to the alternator was loose/damaged between the wire and grounding connector and had welded itself to its connection point had me come back in two weeks later to replace that ground wire harness and told my not to use any hvac utilities like the a.c, heated seats head lights ect anything that drew extra power and surprisingly and thankfully I didn't drive it til the appointment.
Now it sounds like my blower motor is going out example when turned on high occasionally I'll hear a vibration sound near/behind the glove box.
Dealership is saying all these problems are not related and will not fix the damages and still have not found what's causing everything to go out one after the other and blaming it on old age which yes that is a possibility but not like this in my opinion my car was fine just had a bad alternator everything worked perfectly prior to them replacing the alternator.
One more detail I told them in July to check the grounds because I read on this form that's what was most likely causing all my issues and they said they did but obviously they didn't that day
Another thing that was going on but since ended after replacing the ground wire harness was my ESP kept going off on the dash almost everytime I turned the car on and would illuminate the tpms light, traction control light, and power steering light, thankfully it was turned off just by turning the steering wheel fully to the right and left.
Had them do another diagnostic jan 2025 and the radio is still having the communication error and the a.c compressor they said the clutch isn't engaging and that's why it isn't working.
What could be causeing all these problems and is the dealership the cause, I think so they do not (but that's what they all say, any more information is greatly appreciated

You posted this in the wrong forum. You may ask one of the moderators to move it to the proper place. It would get better viewing if it was in the proper place.
