Question 1

How much is a turbocharger for an OPEL Astra 1.0 Turbo 105 hp?

Accepted Answer

A remanufactured turbocharger for the OPEL Astra 1.0 Turbo 105 hp starts at €370.83. This engine takes 2 different references: the price shown is the lowest, the others varying by supplier or production period.

Question 2

Which turbocharger reference fits the 1.0 Turbo 105 hp?

Accepted Answer

The references are 49130-00100, 49130-00117. They are what settle the match on a OPEL K with the 1.0 Turbo 105 hp engine — not the vehicle's trade name, nor its year.

Question 3

Why are several references offered for the 1.0 Turbo 105 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 K?

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 49130-00100.

Question 5

What happens to the old turbocharger from an OPEL Astra 1.0 Turbo 105 hp?

Accepted Answer

Part 49130-00100 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 49130-00100 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, 49130-00100, and fits in place of the part removed.

Question 7

Does turbocharger 49130-00100 fit every K?

Accepted Answer

No: it matches K models fitted with the 1.0 Turbo 105 hp engine. A K running on diesel, or at a different petrol power output, takes another reference.

Question 8

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

Accepted Answer

No. Two Astra of the same year can take different turbochargers depending on their engine. It is the engine-and-power pairing — here 1.0 Turbo 105 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 Astra 1.0 Turbo 105 hp?

Accepted Answer

On this petrol 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 Astra 1.0 Turbo 105 hp go into limp mode?

Accepted Answer

On this 1.0 Turbo 105 hp, the ECU limits the engine when it no longer finds the boost pressure expected for the 105 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 1.0 Turbo 105 hp?

Accepted Answer

On this 1.0 Turbo 105 hp petrol engine, blue smoke means oil is passing, as on a diesel — turbocharger sealing is one candidate among other parts; white smoke points instead to an ignition fault, specific to petrol engines. 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 1.0 Turbo 105 hp a twin-scroll unit?

Accepted Answer

That depends on the reference fitted from the factory: a twin-scroll turbocharger separates the exhaust flows to limit interference between cylinders, an architecture more common on sporting petrol engines. The listing for reference 49130-00100 states the architecture used on this 1.0 Turbo 105 hp.

Question 14

How do I confirm the fault before ordering turbocharger 49130-00100?

Accepted Answer

By a fault code read and a boost pressure check, carried out by a qualified technician, before any order of reference 49130-00100. 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 49130-00100 fit straight onto a 1.0 Turbo 105 hp?

Accepted Answer

Yes: reference 49130-00100 is the original fitment for an OPEL K with the 1.0 Turbo 105 hp engine. It keeps the dimensions, the mounting and the connections of the part removed. Fitting is a job for a qualified automotive technician.
