Frequently Asked Questions
What is "immobilizer"?
The immobilizer system, or "immo", is an anti-theft system installed at the factory. This system consists of a connection between the key, cluster, and ECU of the equipped vehicle. When an error in this connection occurs, the car will not start. Usually, it runs for a second or two, and then shuts itself off. This symptom is often accompanied by a flashing warning light on the cluster and fault code(s) in the ECU.
Why would I need an immobilizer defeat?
An immobilizer defeat is a cost-effective solution to a malfunctioning immobilizer system and can solve many no-start cases. Immobilizer defeats also allow for flexibility in modifying and replacing keys, clusters, and ECUs.
How do I know which option for an immobilizer defeat is right for me?
The part number and ECU type (for example, MED9, ME7.1.1) are labeled on your ECU. When you remove your ECU, take note of these numbers and use them to find the correct immobilizer defeat service for your vehicle. If you're unsure of which service to choose, contact us by clicking the customer service chat bubble at the bottom of the page and we will be glad to assist in your selection.
Which number is the part number?
On the ECU case, there is a label with information on it. The part number is often the number in the largest font, and consists of three groups of three characters each, often followed by one or two letter revisions. Some examples of ECU part numbers include 06A 906 032 HF, 022 906 032 CS, 07K 906 032 AQ, and 1K0 907 115 S. These are just a few examples, there are hundreds of part numbers for VAG ECUs.
How do I find my engine code?
The best place to find your engine code is on the build sticker, which is located under the trunk liner in the spare tire well. Engine codes are also commonly located on a sticker on the timing cover, or stamped on a tab on the head. If you need help finding your engine code, please contact us using the chat bubble at the bottom of the page.

We do not have any dealers or third-party vendors. While you may find someone selling a used 06A Technik tuned ECU, the only way to be sure you're recieving a genuine 06A Technik tune is to buy directly through 06A Technik. Anyone else claiming to flash 06A Technik tunes to ECUs isn't authorized to sell our product. It is most likely a knockoff.
Can I contact you if I need help?
Always. Any service or product purchased from 06A Technik comes with access to technical support and customer service. Please note that if you purchase a used ECU that claims to be 06A Technik tuned from a third party, we have no way to verify that your tune is genuine.

Full, unlimited access to technical support is only guaranteed to customers who purchase directly from 06A Technik.

I ordered a tune with 2-step, but it doesn't work.
This is due to non-functioning hardware on the car that isn't relaying necessary information to the ECU for the launch control feature to engage. Most commonly, this is a bad clutch switch or vehicle speed sensor (VSS). When replacing parts on your car, always use OEM parts when possible.
I can't hear the crackle pop feature.
This is most commonly because you have too much exhaust. Mufflers and other restricting exhaust components quite literally muffle the noise of the crackle pop. The solution to this is to eliminate those components, and install a free-flowing exhaust system.
Can I install larger injectors, an upgraded fuel pump, or water/meth?
No, not without being tuned for it.
what spark plugs should I use for my tuned 1.8T?
NGK BKR7E copper plugs (part number 4644). Gapped to 0.028”.
