Replacement engines

The entire original engine number on replacement engines (replacement = replacement of the engine block, crankshaft, pistons and cylinder head) is filed down at the main works in Kassel, removed, and replaced with a new number.

An example of the procedures followed on a replacement engine is given below.

1. Engine overhaul date (Example: 259 = the 25th calendar week 1999)
2. Original engine identification letters (stamped on by the works in Kassel)
3. The VAG replacement sign (stamped on by the works in Kassel)
4. Before the engine is reinstalled, the authorised workshop itself stamps the original engine number (serial number) onto this area of the engine.
