Hey all!
I've been having a consistent issue with my Mk6 GTI. 65k miles. It currently has a stratified stage one tune. During in town or lower RPM driving, my accessport is showing a consistent knocking where it'll sit at -3.75 for several minutes, with rare spikes over -5. Here's what I've tried so far -
I've been having a consistent issue with my Mk6 GTI. 65k miles. It currently has a stratified stage one tune. During in town or lower RPM driving, my accessport is showing a consistent knocking where it'll sit at -3.75 for several minutes, with rare spikes over -5. Here's what I've tried so far -
- Different tunes. Even on a stage 0 map it'll still knock
- Switched out the intake for a cold air intake. No change
- Had a stock ignition coil go out, swapped to r8 coils, no change
- Different gas stations, 93 oct only, no change
- Different spark plugs, double checked gapping. No change
- Changed the oil, using Mobil 1 0W40. About 3k miles since oil change.
- Gas mileage seems fairly poor - even with calm driving I only got 24mpg with majority casual backroad driving, with my normal driving I average about 22mpg. Not sure if this is related or not.
- I've taken it to mechanics, who can't find anything wrong
- It's a 2014, so it shouldn't be affected by the timing chain issues (right?).
