4-cylinder diesel engine (1.9 l engine) - Edition 08.2010
Procedure
Note
♦
Before carrying out further work, disconnect battery earth
strap. Check whether a coded radio is fitted. Obtain anti-theft
coding first if necessary.
♦
The engine is removed downwards together with the gearbox.
♦
Leave ignition key in ignition lock to prevent steering lock from
engaging.
♦
It is advisable to remove the front wheels before beginning
engine removal. The vehicle can then be lowered on hoist until
the brake disc splash plates are just above the floor. This pro‐
vides the most ergonomic working position regarding acces‐
sibility of engine compartment components.
♦
All cable ties which are opened or cut through when engine is
removed must be replaced in the same position when engine
is installed.
♦
To prevent damage to removed components, place them in
the container for removed parts -V.A.G 1698- .
♦
Some components cannot be removed, or removed only with
difficulty, with the engine installed. Therefore, you should de‐
termine all defective components before removing engine and
renew them while engine is removed.
WARNING
When doing any repair work, especially in the engine com‐
partment, pay attention to the following due to the cramped
conditions:
♦ 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 sufficient clearance to all moving or
hot components.
– Read fault memories of all control units before removal ⇒ Di‐
agnosis tester VAS 5051; Guided fault finding; Vehicle system
test or VAS 5052; Vehicle self-diagnosis .
– With ignition switched off, disconnect earth strap from battery.
One-piece engine cover
For one-piece engine cover, pull engine cover abruptly upwards
at front and right -arrows A-, then pull forwards out of rear fas‐
tening -arrow B-.
