VAG5053 VW/AUDI
To avoid personal injury, instrument damage and/or damage to your
vehicle; do not use the VAG5053 before reading this manual.
This manual describes common test procedures used by experienced
service technicians. Many test procedures require precautions to avoid
accidents that can result in personal injury, and/or damage to your vehicle
or test equipment. Always read your vehicle's service manual and follow its
safety precautions before and during any test or service procedure.
ALWAYS observe the following general safety precautions:
zWhen an engine is running, it produces carbon monoxide, a toxic
and poisonous gas. To prevent serious injury or death from carbon
monoxide poisoning, operate the vehicle ONLY in a well-ventilated
area.
zTo protect your eyes from propelled objects as well as hot or
caustic liquids, always wear approved safety eye protection.
zWhen an engine is running, many parts (such as the coolant fan,
pulleys, fan belt etc.) turn at high speed. To avoid serious injury,
always be aware of moving parts. Keep a safe distance from these
parts as well as other potentially moving objects.
zEngine parts become very hot when the engine is running. To
prevent severe burns, avoid contact with hot engine parts.
zBefore starting an engine for testing or trouble-shooting, make sure
the parking brake is engaged. Put the transmission in park (for
automatic transmission) or neutral (for manual transmission). Block
the drive wheels with suitable blocks.
zConnecting or disconnecting test equipment when the ignition is
ON can damage test equipment and the vehicle's electronic
components. Turn the ignition OFF before connecting the
VAG5053 to or disconnecting the VAG5053 from the vehicle’s Data
Link Connector (DLC).
zTo prevent damage to the on-board computer when taking vehicle
electrical measurements, always use a digital multimeter with at

least 10meg Ohms of impedance.
zFuel and battery vapors are highly flammable. To prevent an
explosion, keep all sparks, heated items and open flames away
from the battery and fuel / fuel vapors. DO NOT SMOKE NEAR
THE VEHICLE DUR-ING TESTING.
zDon't wear loose clothing or jewelry when working on an engine.
Loose clothing can become caught in the fan, pulleys, belts, etc.
Jewelry is highly conductive, and can cause a severe burn if it
makes contact between a power source and ground.

1. Preparation for Testing
The VAG5053 aids in monitoring electronic and emissions-related faults in
your vehicle and retrieving fault codes related to malfunctions in these
systems. Mechanical problems such as low oil level or damaged hoses,
wiring or electrical connectors can cause poor engine performance and
may also cause a “false” fault code. Fix any known mechanical problems
before performing any test. See your vehicle’s service manual or a
mechanic for more information.
Check the following areas before starting any test:
zCheck the engine oil, power steering fluid, transmission fluid (if
applicable), engine coolant and other fluids for proper levels. Top
off low fluid levels if needed.
zMake sure the air filter is clean and in good condition. Make sure
all air filter ducts are properly connected. Check the air filter ducts
for holes, rips or cracks.
zMake sure all engine belts are in good condition. Check for
cracked, torn, brittle, loose or missing belts.
zMake sure mechanical linkages to engine sensors (throttle,
gearshift position, transmission, etc.) are secure and properly
connected. See your vehicle’s service manual for locations.
zCheck all rubber hoses (radiator) and steel hoses (vacuum/fuel) for
leaks, cracks, blockage or other damage. Make sure all hoses are
routed and connected properly.
zMake sure all spark plugs are clean and in good condition. Check
for damaged, loose, disconnected or missing spark plug wires.
zMake sure the battery terminals are clean and tight. Check for
corrosion or broken connections. Check for proper battery and
charging system voltages.
zCheck all electrical wiring and harnesses for proper connection.
Make sure wire insulation is in good condition, and there are no
bare wires.
zMake sure the engine is mechanically sound. If needed, perform a
compression check, engine vacuum check, timing check (if
