3 Location. Over there. Mar 21, 2021. #1. Alright, so let's talk a bit about the naturally aspirated 74kW 8-valve AEH/AKL 1.6 liter petrol engine from Audi A3 8L. I know, I know, it's not the most exciting engine, but hear me out. I've tried searching for some info on how to improve its performance, but whenever I did so, I was met with anThebiggest problem with the CAYC engines is the injectors which are prone to failing. VW switched away from Bosch and decided to use Simens to manufacture the injectors which are far inferior in terms of quality. All 4 of my injectors failed on my A3 but luckily enough, they were all replaced by Audi under warranty. IHave a Audi A3 S-Line Black Edition 1.8 TFSI (Petrol), Recently the oil has been burning more than normal, My car's oil light is coming on every 300 miles instead of the usual estimated 1000-1200 miles from Audi.I had the car put on a oil consumption test and it failed at 304 miles before the light came on.
Thereason your Audi A3 shakes at idle but smooths out when accelerating is that the engine is spinning faster, which smooths out any misfires. If a motor mount is causing the problem, once you put the car into gear, the torque from the engine will hold it against the frame. It can be very jarring when your Audi A3 shakes when idle.
