Mitt uppdrag är att kontrollera bilen.

Because uppdrag is an ett-word (a neuter noun) in Swedish.

• en-word nouns take min: min bil
• ett-word nouns take mitt: mitt uppdrag

So:

• ett uppdrag = an assignment / a mission
• mitt uppdrag = my assignment / my mission

If the noun were an en-word, you would use min instead.

Uppdrag usually means assignment, mission, or task, depending on context.

In this sentence, mitt uppdrag is most naturally:

• my assignment
• my task
• sometimes my mission

It does not usually mean a regular job or profession. For that, Swedish would more often use words like jobb or arbete.

In Swedish, when you use a possessive word like min, mitt, din, hans, hennes, etc., you normally do not use a separate article.

So Swedish says:

• mitt uppdrag = my assignment

not:

• mitt ett uppdrag
• mitt uppdraget

This is similar to English: we say my car, not my the car.

This is a very common Swedish pattern:

• X är att + infinitive

It means something like:

• X is to ...
• X is to do ...
• X is ...ing, depending on how you translate it naturally

So:

• Mitt uppdrag är att kontrollera bilen
  = My assignment is to check the car

Here:

• är = is
• att kontrollera = to check / to inspect

The infinitive att kontrollera explains what the assignment consists of.

Normally, no.

In this sentence, att is the infinitive marker, like English to. After är in this structure, Swedish normally keeps it:

• Mitt uppdrag är att kontrollera bilen

Leaving it out would sound wrong in standard Swedish.

Not usually in this sentence. This is an important false-friend point.

In Swedish, kontrollera often means:

• check
• inspect
• verify

So here kontrollera bilen most likely means:

• check the car
• inspect the car

It usually does not mean to control the car in the English sense of physically operating it or dominating it.

Bilen is the definite form of bil:

• en bil = a car
• bilen = the car

So kontrollera bilen means check the car, not check a car.

Swedish often uses the definite form when both speaker and listener know which thing is being talked about.

Because bilen here just means the car, not necessarily my car.

The possessive mitt belongs to uppdrag, not to bilen:

• mitt uppdrag = my assignment
• bilen = the car

So the sentence means:

• My assignment is to check the car

not:

• My assignment is to check my car

If you wanted to say my car, it would be min bil.

Kontrollera is a verb in the infinitive form.

Here are some forms:

• att kontrollera = to check / to inspect
• kontrollerar = checks / is checking
• kontrollerade = checked
• har kontrollerat = has checked

In the sentence att kontrollera bilen, the infinitive is used because it follows att.

The word order is very straightforward and standard:

• Mitt uppdrag = subject
• är = verb
• att kontrollera bilen = complement

So the structure is basically:

• My assignment
  • is
    • to check the car

This is a normal Swedish sentence pattern.

A rough pronunciation guide for English speakers is:

• mitt ≈ mit
• uppdrag ≈ OOP-drahg
• är ≈ a vowel somewhat like air, but shorter and more Swedish
• att ≈ aht
• kontrollera ≈ kon-tro-LEH-ra
• bilen ≈ BEE-len

A few helpful notes:

• uppdrag has the stress on the second part: upp-DRAG
• the r in Swedish is different from English
• the final -en in bilen is pronounced clearly

Yes. In everyday speech, someone might say kolla bilen, which is more informal and means check the car.

Compare:

• kontrollera bilen = more formal, neutral, or professional
• kolla bilen = more casual

So Mitt uppdrag är att kontrollera bilen sounds perfectly natural, especially in a formal or work-related context.

Because Swedish needs att before the infinitive in this construction.

You can think of it as the equivalent of English to:

• är att kontrollera = is to check

Without att, the sentence would be ungrammatical in standard Swedish.

Yes, it can. Uppdrag is often used in fairly official, professional, or serious contexts.

Depending on the situation, it could mean:

• a work assignment
• an official task
• a mission
• a special duty

So the tone of mitt uppdrag is a bit more formal or purposeful than just saying my job in many contexts.
