SUBJECT: Engine Oil Cap
MODELS: All 1990 (produced 10/89 and 11/89) except 325iX
Situation: During the above mentioned production period, engine oil caps with an improperly hardened tensioning spring were installed. Should the tensioning spring break, pieces will fall into the cylinder head.
Correction: Replace engine oil cap of affected vehicles wfth new oil cap P/N 11 12 9 059 323.
Vehicles Affected:
Checking: Whenever a vehicle (produced within production months 10/89 and 11/89 - except 325iX) visits the workshop, for any reason, inspect the "B" pillar for the presence of Service Action Label # 36. If present, no further action is required.
If not present, proceed as follows:
Remove the oil cap from the engine and inspect for a white paint dot on the inside of the cap. If not present, inspect the back of the cylinder head for a green dot.
If either paint dot is present, the cap has already been inspected at the factory and does not need to be replaced.
If neither paint dot is present, the cap must be replaced.
Service Action Label
Instructions: This Service Action has been assigned code number 36. After the prescribed work has been performed, obtain a label (SD 89-003) and
a) emboss your BMW dealer warranty number in the middle of the label;
b) punch out code number 36 printed on the label;
c) bend label to crease an edge and remove the backing paper. Then affix it to the "B" pillar (on driver's front door) as shown.
If the car affected already has a label from a previous Service Action/ Recall Campaign, affix this new label next to the old one. Do not affix one label on top of another because a number from an underlying label could appear in the punched out hole of the new label.
