Alternator Bosch or Duralast

250,000 KM and still on the original alternator ( 1998 Audi A4 . Bosch 120 Amp Alternator ) . Had to replace a couple of bearings but that's it.

Alternators can be rebuilt. YMMV of course, but I rebuilt the Bosch alternator on my old Mk1 VW Rabbit several times (brush would wear down) with no issues.

I replaced it with a Duralast Gold. After replacing the issue still existed so I replaced the alternator with an OEM Bosch remanufactured unit.

I agree, alternator from autozone is not bad. I replaced mine with a Duralast and never had a problem so far.

My Lucas 18ACR (43 Amp) died shortly after I installed a big electric fan (I moved to Texas and felt it was a good idea), so decided to go with a higher output Bosch. I got tired of searching the parts shops (Advance Auto etc.) for a reconditioned Bosch that might or might not fit... In the end, I took my Lucas to an alternator shop and asked for a Bosch that would fit without modifications.

New Bosch installed Thanks for your help. It was in fact the alternator. Had a NEW Bosch installed by M&M Auto/Cycle in Jersey . Mikes the man when it comes to TDI service.

I am pretty sure that the 120A-Vr is much like all of the later Bosch alts with internal cooling. I just took my 120A 1.8t one apart and it is a PITA.

okay just did mine 14.7x after a cold start...can it be too much ? does that sound reasonble

And while I dont recall Hyundai being one of them, there are certain make/models that need an OEM alternator or they just wont work right (i.e Duralast Alternator in a BMW X5=bad idea)

I figured alternator, so took it to Autozone to scan and everything passed. Then took it to Meineke for them to check and they told me alternator was bad and replaced it. Well my interior lights were still flickering so I took it back and they say seems like the one they installed was defective, so they replace it again with an OEM Bosch and also print me a printout of a bulletin stating that under load lights may flicker and there is no solution.
