Search "T10340 camshaft locking tool" and you'll find kits that look nearly identical but fit different engines. VW's small TSI engines changed a lot between about 2010 and today: earlier 1.2/1.4 TSI engines, the belt-driven EA211 1.0–1.6 family, and the 1.5 TSI Evo. The right tool depends on your exact engine code. This guide sorts out which timing tool kit fits which engine, using the fitment details for every kit we carry.
Step 1: Find Your Engine Code
Your engine code is a three- or four-letter code such as CJZA, CHPA, CXSA or DADA. You'll find it:
- on the vehicle data sticker (often in the spare-wheel well or the service book),
- stamped on the engine block, or
- through a VIN decode. Send us your VIN and we'll check it for you.
Model and year alone aren't enough. A 2016 Golf could have several different engines depending on the market.
Step 2: Match the Kit to the Engine

Before You Start the Job
Our EA211 timing guide walks through the job. A few rules apply whichever kit you use: mark the sprockets before anything comes loose, lock the cams and crank before loosening any sprocket bolt, replace one-time bolts, and turn the engine over by hand twice after the job to recheck timing before you start it. One tooth off on an interference engine can bend valves. Every kit is also in the EA211 collection.
Frequently Asked Questions
How do I find my VW engine code to choose a timing tool kit?
Your engine code is a three- or four-letter code such as CJZA, CHPA, CXSA or DADA. It's on the vehicle data sticker, often in the spare-wheel well or service book, stamped on the engine block, or found through a VIN decode. Model and year alone aren't enough, since a 2016 Golf could have several different engines depending on the market.
Does the 1.5 TSI Evo use the same timing tools as other EA211 engines?
No. The 1.5 TSI Evo (2017+) needs its own tools. The 10-Piece 1.5 TSI Evo Timing Tool Kit is listed for engine codes DACA, DADA, DHFA and DFYA, and includes equivalents of T10340, T10499A and other VW tool numbers. If you have a newer Golf, Jetta, Tiguan, A3 or Octavia with the 1.5 TSI, start there.
Which EA211 timing kit covers the most engines?
The EA211 Cam & Crank Timing Tool Set has the widest coverage, listed for 1.0, 1.2, 1.4 and 1.6 FSI/TSI/TFSI engines across the VW, Audi, SEAT and Skoda lineups. It's a good fit if you work on several EA211 cars. The 1.5 TSI Evo still needs its own dedicated kit.
