Continuation of the hijacking of the Daily thread here. This is @sardo_67 's Golf, and I'm picking up and working to get it up to it's potential.
CURRENT STATE
CURRENT ISSUES
Currently running a starter tune from Malone for the 2060, but dealing with consistent fuel rail pressure codes (P0087) and subsequent limp mode. These were happening at 2500 with previous CR150 tune (Malone didn't properly code for the bigger turbo), but now it seems to be related to... well, something that seems to happen in conjunction with a lambda of about .8, but what exactly isn't clear from the data I've logged. With slow, steady application of the throttle, I can run all the way up to 5000rpm in lower gears, but the amount of power requested in higher gears tends to cause P0087 and limp mode to kick in at lower and lower RPMs. At moderate throttle, it is perfectly driveable, with decent torque and power. Above 3000, it seems to be possible to ask for a lot more power without hitting whatever triggers P0087. The turbo becomes effective fairly low down, maybe a little over 2000, but hard to nail it down without logging full-throttle runs.
Tasks
CURRENT STATE
- Stock intake
- Stock injectors
- GTD2060VRK turbo
- DPF delete
- Custom downpipe
- Driving lights linked to high beams
- SEL package (Lighting/Park Pilot)
- Stock rearview mirrors
CURRENT ISSUES
- Low fuel rail pressure codes when high power requested (P0087)
Vehicle may have excessive battery draw when it should be off (may have left equipment plugged in/hi beam relay?). Operator error.Driver's window does not keep auto-up/auto-down calibration. Likely that lifter needs replacement.- Pre-filter intake runners not installed (being shipped).
- Reverse camera does not retract (still works).
- Driver's window has air leak/noise at highway speeds.
Small cut in valve cover from turbo installer (oil seepage). Epoxied.- Loose oil line behind turbo/oil leak on oil line.
- No skid plate (included, waiting to install)
- Suspension is soft (likely shocks, possibly bushings).
- A/C Condenser has rotted/loose/missing fins (rocks/salt, replacement ready for install).
- No tint.

Tasks
- Collect appropriate logs for Malone to calibrate tune.
- Fuel rail pressures (nominal vs actual), regulator pressures (1 and 2, seem to reflect FRP n/a), Lambda, RPM.
- VNT parameters need to be collected, but may not be useful until FRP issues corrected.
- Consolidate Malone accounts and nail down needed logs.
- Check to see if battery drain was due to VCDS cable being left plugged in.
- Currently running time-vs-voltage test, comparing to GSW.
- Check for correct window regulator recalibration procedure. (Tried, not resolved)
- Also check for possible lubrication of regulator to avoid replacement.
- Valve cover gasket cut needs epoxy to seal (COMPLETED).
- Check for worn/misaligned window seal to cut down on noise
- Filled with paper during highway drive, effectively sealed the leading edge of the window.
- Research rearview camera replacement.
- Order aspherical wing mirrors.
