New Volkswagen Bora 1.9 TDI Turbo – Ref. 751851-5004S

Signs of a worn turbo on your Volkswagen Bora 1.9 TDI 115

On the Bora fitted with the 1.9 TDI 115 engine, a turbocharger that is nearing the end of its life often makes itself known through a noticeable loss of power under load, an unusual whistling noise on acceleration, or the engine warning light coming on. Blue exhaust smoke — a tell-tale sign of abnormal oil consumption — or black smoke caused by insufficient air pressure may also appear. These symptoms are common on the AUY and AJM engines fitted to this model, whose variable-geometry turbo is well known for becoming clogged over time and losing responsiveness.

A new turbo compatible with reference 751851-5004S for the Bora

To restore your Volkswagen Bora to its original performance, this new turbo is compatible with reference 751851-5004S, designed for the 1.9 TDI 115 with AUY or AJM engine codes. Before placing an order, we recommend checking the reference on your old turbo or on the vehicle's identification plate, as some power variants may use different turbos despite having the same engine capacity.

Advice before and after fitting on your Bora TDI 115

Before installing the turbo, carefully check the oil circuit, the lubrication hoses and the air intake: insufficient lubrication, poor-quality oil or a clogged air filter are among the most common causes of premature failure on these 1.9 TDI engines. Also check the condition of the intercooler, as a leak can cause rapid failure of the new unit. When starting up for the first time, prime the turbo with oil before the initial start, then drive gently for the first few kilometres to protect the new part.
