Having some starter issues after completing my O2A swap into my jetta. Using a 1.9AAZ coupled to a CHA code diesel O2A tranny. Starter is a Bosch SR0408x. It's been just over a month since I did the swap with a brand new starter and yesterday it decided to stop working. For the time it did work it sounded fairly sluggish to crank as opposed to my older O2O starter. I checked my grounds and voltage and everything is in order, is it possible that I have a starter that is not strong enough? Everywhere I've called have listed the above mentioned starter as the correct one for diesels.
Need some help sourcing out a proper starter, any input?
