4-cyl. injection engine (1.8 and 2.0 l engine, chain drive) - Edition 08.2018
– Clean water drain -arrow- and lower part of air filter.
– When installing the air filter element, check that it is properly
centred in the retainer in lower part of air filter.
– Place upper part of air filter carefully on lower part of air filter
without exerting excessive force. Make sure the upper part of
the air filter is fitted straight on the air filter element (note po‐
sition of sealing lip on air filter element).
Continue installation in reverse order of removal.

Removing and installing air mass meter
- G70-
– Separate electrical connector -1- on air mass meter - G70- .
– Unscrew both bolts from air mass meter - G70- and carefully
pull air mass meter - G70- out of guide on air filter housing.
Installing
To ensure proper operation of the air mass meter - G70- it is im‐
portant to observe the following instructions and comply with the
procedures described.
Note
♦ If the air filter element is very dirty or wet, dirt or water could
reach the air mass meter - G70- and affect the air mass value.
This would lead to loss of power, since a smaller injection
quantity is calculated.
♦ Always use genuine part for air filter element.
♦ Use a silicone-free lubricant when installing the intake hose.
♦ Secure all hose connections with the correct type of hose clips
(same as original equipment) ⇒ EKTA (Electronic parts cata‐
logue) .
– Check air mass meter and intake hose for salt residue, dirt and
leaves (engine intake side).
– Check for contamination of intake duct as far as air filter ele‐
ment. If contamination is found, remove salt residues, dirt and
leaves from top and bottom part of air filter housing by rinsing
out or using a vacuum cleaner if necessary. Removing and
installing air filter ⇒ page 468
Continue installation in reverse order of removal.
