For the SEAT Toledo 3 (5P2) in 1.8 TFSI 160 hp (118 kW petrol), the autoKUR catalogue holds 1 exchange-standard reference(s). At equal displacement, two outputs do not call for the same part.
Engine specification: 1798 cm³, petrol, built from 01/2007 to 05/2009. Matching part number: 5303 988 0136 (BorgWarner - KKK). Compare with the code stamped on your part.
A remanufactured turbocharger for the SEAT Toledo 1.8 TFSI 160 CV starts at €404.00. This engine takes a single reference, 5303 988 0136: the price shown is the one part that fits your vehicle, with no variant to compare.
The reference is 5303 988 0136. It is what settles the match on a SEAT 3 (5P2) with the 1.8 TFSI 160 CV engine — not the vehicle's trade name, nor its year.
Because this engine was built with a single turbocharger. Other Toledo engines carry several references depending on the production period; here the choice is unique, which rules out any risk of error.
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 5303 988 0136.
Part 5303 988 0136 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.
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, 5303 988 0136, and fits in place of the part removed.
No: it matches 3 (5P2) models fitted with the 1.8 TFSI 160 CV engine. A 3 (5P2) running on diesel, or at a different petrol power output, takes another reference.
No. Two Toledo of the same year can take different turbochargers depending on their engine. It is the engine-and-power pairing — here 1.8 TFSI 160 CV — that determines the reference, and the code on the removed part that confirms it.
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.
On this 1.8 TFSI 160 CV, the ECU limits the engine when it no longer finds the boost pressure expected for the 160 CV rated output. A turbocharger that no longer regulates pressure correctly is one possible cause, alongside an air leak or a faulty pressure sensor.
On this 1.8 TFSI 160 CV 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.
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.
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 5303 988 0136 states the architecture used on this 1.8 TFSI 160 CV.
By a fault code read and a boost pressure check, carried out by a qualified technician, before any order of reference 5303 988 0136. That check separates a failed turbocharger from an air leak or a faulty sensor — three faults with similar symptoms but different remedies.
Yes: reference 5303 988 0136 is the original fitment for a SEAT 3 (5P2) with the 1.8 TFSI 160 CV engine. It keeps the dimensions, the mounting and the connections of the part removed. Fitting is a job for a qualified automotive technician.
