1.1 Engine number, engine data
“The engine identification characters” and the “serial number” are
located on the sticker -arrow- at the top timing belt guard.
The “engine identification characters” and “serial numbers” are
also indicated on the engine above the engine connection with
the gearbox, on the vehicle data sticker and on the engine control
unit.
♦ Starting with the letter “C”, new four digit engine codes have
been introduced.
♦ The first 3 digits of the engine identification characters refer to
the displacement and the mechanical construction of the en‐
gine. They are type-punched on the cylinder block including
the serial number.
♦ The 4th digit refers to the output and torque of the engine and
depends upon the engine - J623- control unit.

2.1 Safety precautions when working on
fuel supply system
WARNING
Fuel under high pressure creates a risk of injury.
Leaking fuel creates a fire hazard.
♦ The fuel system is under pressure! Before opening the
high-pressure system, the fuel pressure must be reduced
to residual pressure
⇒ “3.10 Reduce pressure in the high-pressure system”,
page 10 .
♦ The safety measures for the pressure reduction in the high
pressure system must be observed.
♦ To reduce the residual pressure (about 0.7 MPa or 7 bar),
the connection point must be opened »immediately« after
the pressure has been reduced. Place a cleaning cloth
around the connection point.
♦ Wear protective gloves.
♦ Wear safety goggles.
♦ Fuel pump is activated by switching on ignition and via driver
door contact switch. Before opening the fuel system and for
reasons of safety, if the battery is not disconnected, the con‐
nector must be disconnected from the fuel pump.
♦ Take out fuse for fuel pump control unit - J538- ⇒ Current flow
diagrams, Electrical fault finding and Fitting locations.
Caution
There is a risk of destruction of electronic components when
disconnecting the battery.
♦ Observe notes on procedure for disconnecting the battery.
Disconnect the battery only when the ⇒ Electrical System; Rep.
gr. 27 battery is disconnected.

Caution
When undertaking all assembly work, particularly in the engine
compartment due to its cramped construction, please observe
the following:
♦ Route all the various lines (e.g. for fuel, hydraulics, acti‐
vated charcoal filter system, coolant and refrigerant, brake
fluid and vacuum) and electrical wiring in their original po‐
sitions.
♦ Ensure that there is adequate free access to all moving or
hot components.
♦ Clean connection points and their environment thoroughly with
engine or brake cleaner and dry the cleaned area thoroughly
before loosening.
♦ Open closed lines and connections immediately with suitable
screen caps.
♦ Place removed parts on a clean surface and cover. Use only
lint-free cloths!
♦ Only install clean parts: Remove spare parts from their wrap‐
ping immediately before fitting. Do not use any parts which
have been stored unwrapped (e.g. in tool boxes etc.).
♦ When the system is open: Do not work with compressed air.
Avoid moving the vehicle.
♦ Protect electrical plug connections from dirt and moisture and
only connect them when dry.
♦ The extraction hose of an exhaust extraction system which is
switched on, must be positioned close to the assembly open‐
ing of the fuel tank in order to extract the released fuel vapours,
even before the work is commenced. If no exhaust extraction
system is available, a radial fan (motor not in air flow of fan)
with a delivery volume of more than 15 m
3
/h must be used.
♦ Prevent skin contact with fuel!
♦ Wear fuel-resistant gloves!
2.2 Safety measures for working on vehi‐
cles with start/stop system
When working on vehicles with start/stop system, please observe
the following:
WARNING
There is risk of injury from automatic engine starting on vehi‐
cles with start/stop system.
♦ In vehicles with an activated start-stop system (indicated
by a message in the dash panel insert), the engine can
start automatically if necessary.
♦ It is therefore necessary to ensure that the start-stop sys‐
tem is deactivated when carrying out work on the vehicle
(switch ignition off, if required switch ignition on again).

2.3 Safety precautions during road tests in
which testing and measuring equipment
is used
Note the following if testers and measuring instruments must be
used during a road test:
WARNING
There is a risk of accident from deflection and insufficient se‐
curing of testers and measuring instruments.
There is also a hazard from the release of the passenger airbag
in the event of an accident.
• Using testers and measuring instruments during driving
operation creates a risk of deflection.
• Increased risk of injury from unsecured testers and meas‐
uring instruments must be prevented.
♦ Testers and measuring instruments must always be se‐
cured on the rear seat using a seat belt and by a 2nd
person on the rear seat.
2.4 Safety precautions when working on
cooling system
WARNING
Steam may escape when expansion tank is opened.
♦ Wear eye protection and protective clothing to avoid eye
injuries and scalding.
♦ Cover cap with cloth and open carefully.
Caution
When undertaking all assembly work, particularly in the engine
compartment due to its cramped construction, please observe
the following:
♦ Route all the various lines (e.g. for fuel, hydraulics, acti‐
vated charcoal filter system, coolant and refrigerant, brake
fluid and vacuum) and electrical wiring in their original po‐
sitions.
♦ To avoid damage to lines, ensure sufficient clearance from
all moving or hot components.

If you've landed on this page, it's likely that you already understand the importance of routine maintenance for your Škoda vehicle and that repairing it yourself is always the most cost-effective solution in the long term.
And although Škoda vehicles are generally quite reliable, certain parts will inevitably wear out over time and require replacement — and let's not forget that dealership and repair shop prices are skyrocketing these days.
Fortunately, an OEM Škoda repair manual will allow you to maintain and repair your vehicle on your own terms!
Indeed, this 2013 SKODA Octavia Download Service & Repair Manual is identical to what Škoda technicians use to service and maintain your vehicle and includes all the manufacturer's recommended troubleshooting and replacement procedures. Thanks to the included step-by-step instructions, troubleshooting charts, exploded-view illustrations, wiring diagrams, and clear images, you'll have everything you need to repair your vehicle and keep the tow truck at bay.
It's also worth noting that digital manuals are far more user-friendly than traditional hardbound books. You won't have to sort through hundreds of pages to find what you're looking for, and you won't have to worry about dirty hands, misplaced pages, or a bunch of manuals collecting dust on your garage shelves. Digital manuals can also be stored on your phone or laptop, ensuring that they're always nearby when you need them.
Of course, if you prefer a physical copy, you can still print out specific pages or the entire manual. Nonetheless, and regardless of how you use it, a good repair manual will always have your back, helping you keep your Škoda in excellent condition at an affordable cost!
