Removing engine

The engine is removed from below with the gearbox
– Read fault memories of all control units before removal: ⇒ 

Diagnostic tester VAS 5051; Guided fault finding; Vehicle sys‐

tem test or VAS 5052; Vehicle self-diagnosis .

Note

♦

To enable the propshaft to rotate freely, move selector lever

to the „N“ position.

♦

Leave key in ignition to prevent steering wheel lock from en‐

gaging.

♦

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.

♦

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.

♦

To prevent damage to removed components, place them in

the container for removed parts -V.A.G 1698- .

♦

All cable ties which are opened or cut through when engine is

removed must be replaced in the same position when engine

is installed.
