What it is
This is a complete timing belt service kit for the VW 1.9L ALH TDI engine, built to the 100,000-mile change interval. "Complete" here means everything needed for the job is included — belt, water pump, all rollers, full hardware/bolt kit, and coolant. No additional parts need to be purchased separately for a standard belt change.
Why the 100,000-mile interval applies to all ALH years, including early ones — this is a factual timeline
| Year | Change | Resulting Interval |
|---|---|---|
| 1999.5 (earliest ALH) | Original timing belt part 038109119D | 40,000 mi (automatic) / 60,000 mi (manual) |
| 2002 | Belt updated to part 038109119M | 60,000 mi (automatic) / 80,000 mi (manual) |
| 2003 | Large roller updated to 038109244M (or H, depending on brand) | 100,000 mi, regardless of transmission |
The parts in this kit reflect the 2003 update, and they are backward-compatible with all earlier ALH cars — 1998 New Beetle through 2003 Golf/Jetta/New Beetle. Installing this kit on an older ALH car upgrades it to the longer 100,000-mile interval regardless of the car's original factory interval.
Parts sourcing
All parts are sourced from VW's own OEM suppliers — the same parts sold at a VW dealer, without VW-branded packaging or dealer markup.

Fitment
Important fitment note
Some 2003 Jetta Wagons use shorter BRM-style harmonic balancer bolts instead of the standard ALH bolts. Confirm which bolt type your car uses before installing.
When to choose this kit vs. the High Mileage kit
This is the standard kit for a car's first (or any single) timing belt service. If your car is already on its second timing belt change, KermaTDI's High Mileage kit includes everything in this kit plus additional parts (EGR seal, intake manifold gasket, serpentine tensioner, crank bolt/seal, extra studs) that are typically due for replacement by the second interval.
Common questions
Does this kit work on a 1999.5 ALH that originally had a 40,000-mile interval? Yes. Installing this kit's updated parts brings any ALH year up to the 100,000-mile interval, regardless of what interval the car originally shipped with.
Does this kit include coolant and all mounting hardware, or just the belt? Both are included — 1.5L of coolant and the complete bolt kit, not sold separately.
Is this the same kit VW dealers use, or a generic aftermarket kit? Same parts, sourced from VW's own suppliers — not VW-branded packaging, but the identical components.
Should I buy this kit or the High Mileage kit? This kit for a first belt service; the High Mileage kit if your car is already on its second timing belt change.
Do all 2003 Jetta Wagons use the same harmonic balancer bolt? No — some use shorter BRM-style bolts. Confirm before installing.
