Diagnosing a turbo fault on a SEAT Leon 1.9 TDI 90 before ordering
Before replacing the turbocharger on your SEAT Leon I fitted with the 1.9 TDI 90 engine, it is essential to confirm that the turbo is actually the cause of the problem. Checking the fault code with a diagnostic tool, testing the boost pressure and visually inspecting the turbo shaft (radial play, oil traces on the intake or exhaust side) will help rule out other possible causes, such as a split vacuum hose or a faulty pressure sensor. On this 1896 cm³ diesel engine, the relevant engine codes are AGR and ALH: make sure you note the code on the engine plate and compare the reference engraved on your old turbo with those listed on this page before placing an order.
Compatibility of the new turbo for the SEAT Leon 1.9 TDI 90
This new turbo is compatible with reference 454159-5002S and fits the SEAT Leon I with the 1.9 TDI 90 engine, engine codes AGR and ALH. We strongly recommend that you always check the reference on your original turbo, as several variants of housings or actuators may exist depending on the vehicle's year of manufacture.
Exchange basis and warranty for this SEAT Leon turbo
This turbo is sold on an exchange basis: in accordance with our Terms and Conditions, return of your old turbo is required. It is only collected after the new turbo has been delivered and fitted, so your SEAT Leon is not left off the road. A 12-month parts warranty applies, subject to fitting being carried out by a qualified professional. Payment can be spread over several instalments, in up to 10 instalments.
Advice before fitting the turbo on the 1.9 TDI 90
On AGR and ALH engines, premature turbo failure is frequently caused by insufficient lubrication, unsuitable oil quality or missed oil change intervals, which leads to the oil channels in the central cartridge becoming blocked. A clogged air filter or a damaged intercooler can also disrupt turbo operation and accelerate wear. Before fitting the new unit, check the oil circuit (hoses, return line), the air intake and the condition of the intercooler. On first start-up, prime the turbo by pouring fresh oil into the oil feed to lubricate the bearings before starting the engine.
