Product Details
The Audi 2.5L TFSI turbocharged 5-cylinder engine utilizes a highly complex dual-chain timing system mounted at the rear of the engine block. While the upper chain drives the camshafts, this lower primary timing chain (frequently referred to as the intermediate shaft chain) is responsible for transferring rotational power directly from the crankshaft up to the intermediate idler gear.
Due to the extreme torsional loads, rapid acceleration forces, and aggressive heat cycles produced by a 400+ horsepower engine, the metal links in this 110-link lower chain will eventually fatigue and stretch over tens of thousands of miles. When the lower chain stretches beyond the physical limit of its hydraulic tensioner to take up the slack, the engine loses exact mechanical synchronization. Warning signs include a harsh, metallic chain rattle from the lower rear of the engine block during cold starts, an erratic idle, and engine control module fault codes indicating crankshaft position deviations. If the chain stretch becomes severe enough to jump teeth on the lower crankshaft sprocket, the resulting valve-to-piston contact will instantly and completely destroy the engine.
Replacing your stretched, fatigued factory lower chain with this precision-manufactured, OE-spec 110-link silent chain from Febi Bilstein restores pristine lower-end mechanical timing, curing cold-start rattle and ensuring your 5-cylinder powerhouse remains tightly synchronized and reliable.
Features:
Precision-manufactured 110-link closed silent timing chain engineered for the lower intermediate shaft drive on the 2.5L TFSI
Restores exact mechanical synchronization between the crankshaft and the intermediate idler gear
Prevents catastrophic engine failure due to chain jump and lower-end timing loss
Cures lower-end cold-start chain slap and resolves crankshaft correlation fault codes
