Hi,
I am chasing an issue that makes my S3 occasionly splutter/hesitate when I use wide open throttle. The car will hesitate and produce a lot of pops from the exaust then take off as normal.
I have replaced a fair few parts now chasing this including PCV, high and low pressure injectors, intake manifold walnut blast, HPFP and cam follower, coil packs, spark plugs, cam adjuster magents and valves, diverter valve so far.
Some of these did need replacing as logging with VCDS showed the HPFP not maintaining specified pressure and cam timing was erratic so it's not all bad and atleast for piece of mind these parts are all fresh now!
I am going to log my LPFP and HPFP at the same time on a drive but did and output test and am wondering if the LPFP sounds like it is on the way out. I have added a link to a clip of the test, can anyone tell me if this sounds normal or unhealthy please?
