What it is
This is a bench-tuned ECU service for the VW 1.9L ALH TDI, covering 2000–2003 later-production models. Your ECU is removed from the car and sent to KermaTDI for programming, then shipped back for reinstallation. This is not an OBD flash and does not include the Q-Pro programmer device — there's no hardware left in the car for self-service re-flashing.
How the tune is written
Rather than fixed "stages," KermaTDI writes each tune individually based on your car's specific modifications and your desired driving characteristics — smoke level, throttle response, etc. This is a personalized calibration, not a generic file applied to every ALH.
How the service works
Your car is off the road for the duration of ECU removal, shipping both directions, and KermaTDI's programming turnaround. Contact KermaTDI directly for current turnaround estimates.
Switching back to stock
Because there's no Q-Pro device involved, reverting to a stock tune (for a dealer visit, warranty work, etc.) means sending the ECU back to KermaTDI again, rather than flipping a switch on a handheld programmer. If you expect to need frequent stock/tuned switching, KermaTDI's Q-Pro-based ALH tuning option (a separate listing) is built for that use case instead.
Future tune updates
Included at no charge when you purchase future upgrade parts (turbos, injectors, etc.) from KermaTDI — though since each update means sending the ECU back in, confirm current turnaround expectations for updates under this bench-tune path.
Recommended combinations
Chip tuning plus injectors is a common starting combination. Turn-key packages bundling multiple upgrades are also available — contact KermaTDI for a recommendation suited to your goals.
Fitment
2000–2003 VW Golf, Jetta, and New Beetle, later-production ALH engine.
Order requirements
Vehicle year/model and transmission type (manual or auto) required at checkout.
Common questions
Do I need to remove my own ECU, or does KermaTDI do that? You remove and ship the ECU yourself; KermaTDI does not come to the car. Contact them after ordering to coordinate the process.
How long is my car down for this? Depends on ECU removal, round-trip shipping, and KermaTDI's programming turnaround — contact KermaTDI for a current estimate, since it isn't stated on this listing.
Can I switch back to stock for a dealer visit? Only by sending the ECU back in — there's no onboard device to toggle between stock and tuned like the Q-Pro option offers.
What's the difference between this and the Q-Pro ALH tuning listing? This is a bench tune (ECU mailed in, no device kept). The Q-Pro version flashes over OBD and leaves you with a reusable device for self-managing stock/tuned switching and future re-flashes without shipping the ECU each time.
