What do you need the engine code for?
The engine code gives you important information on your engine and the individual components that are installed. You need the code when you want to replace engine parts. So you don’t run the risk of installing parts that don’t fit your 1.8T engine. Of course, you also need the engine code when you want to install a replacement engine. As you can see from our table, the code is not necessarily dependent on the brand. Many VW and Audi models, for instance, have the same engine.

Where do you find the engine code?
Depending on the vehicle, you’ll find the engine code in different places. It can be directly on the engine block, stamped in or on a type plate or else on the cover of the toothed belt. The operating manual might also contain the engine code. If you can’t find it in any of these places, a repair shop can help you.
Do you need help?
We can help you with the engine code. Just call us or write us an e-mail.

Hi! As far as we know, it has only the 1.8L EA888, not a 1.8T(EA113/EA827). Do you have a source for this information?
