ALH ECO TDI Kit — Max MPG Build (S7 Turbo + DLC520 Nozzles + Q-PRO+ Eco Tune) | KermaTDI

 What it is
This is a complete parts-and-tuning package for the VW 1.9L ALH TDI, built specifically to maximize fuel economy while also adding some power — it's not a pure power kit, and it's not a pure economy tune. It combines a turbo upgrade, new injector nozzles with calibration, a MAP sensor upgrade, and an eco-focused ECU tune.

Measured results

• Fuel economy: typically 10–12% MPG improvement
• Power: +30% wheel horsepower and torque
• Described by KermaTDI as "a perfect balance between HP and MPG" — this is not the kit to choose if maximum power alone is the goal.

What's included

• S7 turbo
• Braided steel oil supply line
• Full turbo installation kit
• Turbo adapter to stock SMIC plumbing
• DLC520 injector nozzles with calibration
• 3-bar MAP sensor and adapter
• Q-PRO+ module with eco-specific tuning
• Clutch lever, release clip, and pivot pin kit (included at no extra cost)
• Transmission stretch bolts, where applicable to your car

Injector service — two options, pick one

• With Hot Swap add-on: Refundable core exchange — you get replacement injectors back without waiting on your originals.
• Without Hot Swap: You send in your own injectors for calibration/installation; they ship back to you directly from KermaTDI's fuel shop once complete. This takes longer since it depends on your injectors' turnaround.

Optional clutch upgrade — not required
A clutch option is available but not necessary for this kit to function. Two choices if selected: Stage 2 Daily (keeps stock-like pedal feel) or Endurance (more aggressive pedal feel).

Rear main seal
Only recommended for replacement if it's already leaking — not a standard inclusion or requirement.

Fitment — important exclusion for early ALH years
Covers 1999–2003 ALH-engine VW Golf, Jetta, Jetta Wagon, and New Beetle. The earliest ALH cars — 1998–99 Beetle and 1999–99.5 Jetta/Golf — are not automatically covered. Call 877-537-6283 before ordering if your car falls in this early range, since parts compatibility differs.

Common questions

Is this a power kit or a fuel economy kit? Both, balanced — expect roughly 10–12% better MPG and about 30% more wheel HP/torque, not maximum output in either direction alone.

Do I need to send in my injectors, or can I avoid downtime? Add the Hot Swap option for a refundable core exchange with no wait on your own injectors. Without it, you send yours in and they're calibrated and returned.

Does my early ALH (98-99 Beetle, 99-99.5 Jetta/Golf) qualify for this kit as listed? Not automatically — call KermaTDI first to confirm compatibility for these earliest ALH years.

Is the clutch upgrade required for this kit to work? No, it's optional. The kit functions fully without it.

When should I replace the rear main seal as part of this install? Only if it's already leaking — it's not a standard part of this kit.
