Draper Expert Engine Timing Kit ETK110 (Audi)

Precision Timing Work on Audi's Iconic Five-Cylinder TFSI Engine

Audi's 2.5cc TFSI five-cylinder engine is one of the most celebrated performance engines in modern European motoring — fitted across the RS3, RS Q3 and TT RS, and renowned for its distinctive sound, turbocharged performance and engineering complexity. It is also an engine where timing chain work demands absolute precision and the correct dedicated tooling.

The camshaft drive chain on this engine family must be removed and replaced with the engine locked precisely in the timed position — with the camshafts, crankshaft and chain tensioner all held securely in their correct alignment. Any deviation risks the camshafts moving out of time during the procedure, with potentially catastrophic consequences for the engine on startup.

The Draper Expert ETK110 provides everything needed to carry out this procedure safely and correctly, with a 6-piece OEM-equivalent tool set that replicates the exact dealer workshop tooling for this engine family.

OEM-Equivalent Tooling — Correct Fit, Every Time

Each of the six tools in the ETK110 set is manufactured to the OEM equivalent specification of the original Audi/VAG dealer workshop tooling, with OEM reference numbers confirmed for every applicable piece:

• 1 x Camshaft locking tool — OEM ref. T40070
• 1 x Camshaft adjuster holding tool — OEM ref. T40079
• 1 x Crankshaft pulley bolt adaptor — OEM ref. T03003
• 1 x Crankshaft alignment pin — OEM ref. T40069
• 1 x Tensioner locking pins — OEM ref. T03006
• 2 x M8 x 50mm bolts — for securing locking tool positions during the procedure

The OEM reference numbers confirm that each tool is dimensioned and profiled to engage correctly with the specific geometry of this engine — providing the same secure, accurate lock-up achieved using the original manufacturer tooling at an Audi dealer workshop.

What Each Tool Does

Camshaft Locking Tool (T40070) Locks the camshafts in the correct timed position before the drive chain is disturbed. With five cylinders and a complex variable valve timing system, maintaining precise camshaft position throughout the chain replacement procedure is critical. The camshaft locking tool engages directly with the camshaft and holds it securely in the position required for correct timing reassembly.

Camshaft Adjuster Holding Tool (T40079) Holds the camshaft adjuster (variable valve timing actuator) in position while the camshaft locking tool is in place. This prevents the adjuster from rotating independently of the camshaft during chain removal and replacement, maintaining the correct phasing relationship throughout the procedure.

Crankshaft Pulley Bolt Adaptor (T03003) Allows the crankshaft to be rotated to the timing position using a standard breaker bar or torque wrench, and facilitates correct torque application to the crankshaft pulley bolt during reassembly. Correct crankshaft bolt torque is essential on this engine — an adaptor that fits precisely to the bolt head geometry ensures accurate torque transfer without risk of rounding or slipping.

Crankshaft Alignment Pin (T40069) Locks the crankshaft in the correct timing position once it has been rotated to top dead centre on the compression stroke. With the crankshaft pinned, the camshaft locking tool can then be applied with confidence that the engine is correctly positioned throughout the procedure.

Tensioner Locking Pins (T03006) Lock the chain tensioner in the retracted position during chain removal, preventing it from extending and causing obstruction during the procedure. The tensioner must be correctly locked and released at the right point in the reassembly sequence — the dedicated locking pins ensure this is done safely and at the correct position.

M8 x 50mm Bolts Secure the locking tools in position during the timing procedure, ensuring they cannot be inadvertently displaced during chain removal and refitting.

Vehicle and Engine Code Compatibility

The ETK110 is specifically designed for the following Audi models and engine codes:

Engine Codes: CEPA, CEPB, CTSA, CZGA, CZGB

Always confirm the engine code from the vehicle identification plate or service documentation before ordering. The engine code is typically found on a sticker in the engine bay or stamped on the engine block.

Why the Correct Timing Kit is Non-Negotiable

Engine timing chain work on the Audi 2.5 TFSI is not a job where improvisation is an option. The five-cylinder configuration, combined with Audi's variable valve timing system, means there are multiple components that must be locked in precise alignment simultaneously. Using incorrect tooling — or attempting to hold components by other means — risks the camshafts or crankshaft moving out of position during the procedure. If the engine is then turned over with timing out, the result is typically valve-to-piston contact and severe engine damage.

The ETK110 eliminates this risk by providing the correct, purpose-designed tool for every locking and holding step in the procedure — the same tools used by Audi's own dealer network.

Q: Which Audi models is the ETK110 compatible with? The ETK110 is designed for the Audi RS Q3 TFSI (2013–2017), Audi RS3 and RS3 Plus (2010–2017) and Audi TT (2009–2014), all fitted with the 2.5cc TFSI five-cylinder engine. Compatible engine codes are CEPA, CEPB, CTSA, CZGA and CZGB. Always confirm your engine code before ordering.

Q: How do I find my Audi's engine code? The engine code is typically found on a sticker in the engine bay — often on the bulkhead or strut brace — or stamped directly on the engine block. It can also be confirmed via the vehicle identification plate, the V5C registration document, or by entering the VIN into the Audi parts system or an online VAG parts database.

Q: Is this the complete tool set needed for timing chain replacement on the 2.5 TFSI? The ETK110 provides all six tools required to lock and hold the engine in the correct timed position for camshaft drive chain removal and replacement on the covered engine family. All M8 fixing bolts are included. You will additionally require standard workshop equipment including a torque wrench, socket set and the vehicle-specific camshaft chain replacement parts. Always refer to the manufacturer workshop manual or a recognised technical procedure guide for the full step-by-step process.

Q: What does the camshaft adjuster holding tool do? The camshaft adjuster holding tool (T40079) prevents the variable valve timing actuator from rotating independently of the camshaft while the locking tool is in place. On Audi's variable valve timing system, the adjuster can move relative to the camshaft when the chain tension is released — if not held in position, this would alter the cam timing relationship and complicate correct reassembly.

Q: Why must the tensioner be locked during chain replacement? The hydraulic or mechanical chain tensioner is spring-loaded to maintain constant pressure on the chain. When the chain is removed, if the tensioner is not locked in the retracted position it will extend fully — making it impossible to refit the new chain without either damaging the tensioner or forcing it back incorrectly. The tensioner locking pins hold it safely retracted throughout the chain removal and refitting process.

Q: Is this suitable for use by an experienced home mechanic? Camshaft timing chain work on the Audi 2.5 TFSI is a complex procedure that requires a solid understanding of engine timing systems, access to the vehicle workshop manual, and confidence working to precise torque specifications. For those with the appropriate level of experience and knowledge, the ETK110 provides the correct OEM-equivalent tooling to carry out the job safely. If in any doubt, the procedure should be entrusted to a qualified mechanic or Audi specialist.
