Question 1

How much is a turbocharger for a SKODA Octavia 1.9 TDI 110 hp?

Accepted Answer

A remanufactured turbocharger for the SKODA Octavia 1.9 TDI 110 hp starts at €254.00. This engine takes 3 different references: the price shown is the lowest, the others varying by supplier or production period.

Question 2

Which turbocharger reference fits the 1.9 TDI 110 hp?

Accepted Answer

The references are 5439 988 0017, 713672-5006S, 713673-5006S. They are what settle the match on a SKODA 1 (1U2 / 1U5) with the 1.9 TDI 110 hp engine — not the vehicle's trade name, nor its year.

Question 3

Why are several references offered for the 1.9 TDI 110 hp?

Accepted Answer

Because this engine was built with several turbochargers depending on the production period or the original supplier. Each reference matches a precise variant; the code read on the removed part settles which one fits.

Question 4

Where is the reference found on a turbocharger removed from a 1 (1U2 / 1U5)?

Accepted Answer

It is on the riveted plate of the centre housing, on the compressor side. The plate holds the marking even on a part coated with oil and soot. It is the only reading that confirms the match with 5439 988 0017.

Question 5

What happens to the old turbocharger from a SKODA Octavia 1.9 TDI 110 hp?

Accepted Answer

Part 5439 988 0017 is sold as an exchange unit: it has already been remanufactured and balanced, and the turbocharger you remove goes back into the reconditioning circuit. Return terms are stated at checkout.

Question 6

How does exchange turbocharger 5439 988 0017 differ from a new part?

Accepted Answer

An exchange turbocharger is an original part restored to working order: wear parts are replaced and the rotating assembly is rebalanced. It carries the same reference, 5439 988 0017, and fits in place of the part removed.

Question 7

Does turbocharger 5439 988 0017 fit every 1 (1U2 / 1U5)?

Accepted Answer

No: it matches 1 (1U2 / 1U5) models fitted with the 1.9 TDI 110 hp engine. A 1 (1U2 / 1U5) running on petrol, or at a different diesel power output, takes another reference.

Question 8

Is the year of my Octavia enough to choose the turbocharger?

Accepted Answer

No. Two Octavia of the same year can take different turbochargers depending on their engine. It is the engine-and-power pairing — here 1.9 TDI 110 hp — that determines the reference, and the code on the removed part that confirms it.

Question 9

How do I spot a worn turbocharger on an Octavia 1.9 TDI 110 hp?

Accepted Answer

On this diesel engine, a turbocharger nearing the end of its life shows up as a loss of power under acceleration, smoke at the exhaust, a whistle rising with engine speed and a drop into limp mode. These signs overlap with other intake faults: diagnosis is a job for a qualified technician.

Question 10

Why does my Octavia 1.9 TDI 110 hp go into limp mode?

Accepted Answer

On this 1.9 TDI 110 hp, the ECU limits the engine when it no longer finds the boost pressure expected for the 110 hp rated output. A turbocharger that no longer regulates pressure correctly is one possible cause, alongside an air leak or a faulty pressure sensor.

Question 11

What does exhaust smoke mean on a 1.9 TDI 110 hp?

Accepted Answer

On this 1.9 TDI 110 hp diesel engine, blue smoke means oil is passing — turbocharger sealing is one candidate among other parts; black smoke means an over-rich burn, so a lack of air at the intake. Colour guides the diagnosis, it does not replace it.

Question 12

Does a whistle under acceleration always come from the turbocharger?

Accepted Answer

No. The whistle can come from the turbocharger itself, but equally from a leak on an intake hose, the intercooler or the wastegate. Noise alone is not enough to condemn the part.

Question 13

Is the turbocharger on the 1.9 TDI 110 hp a variable-geometry unit?

Accepted Answer

Yes. This diesel engine takes a variable-geometry turbocharger, whose movable vanes adapt boost to engine speed. It is the part that seizes most often on this type of engine, and it is among what is restored on reference 5439 988 0017.

Question 14

How do I confirm the fault before ordering turbocharger 5439 988 0017?

Accepted Answer

By a fault code read and a boost pressure check, carried out by a qualified technician, before any order of reference 5439 988 0017. That check separates a failed turbocharger from an air leak or a faulty sensor — three faults with similar symptoms but different remedies.

Question 15

Does turbocharger 5439 988 0017 fit straight onto a 1.9 TDI 110 hp?

Accepted Answer

Yes: reference 5439 988 0017 is the original fitment for a SKODA 1 (1U2 / 1U5) with the 1.9 TDI 110 hp engine. It keeps the dimensions, the mounting and the connections of the part removed. Fitting is a job for a qualified automotive technician.
