A3 1.4TFSI Engine Rattle On Cold Start… Timing Chain? My 1.4tfsi developed a problem last weekend… so basically when i turn the car on a cold start I hear a loud rattling towards the front of the engine.

Why does my 1.4tfsi rattle on a cold start?

My 1.4tfsi developed a problem last weekend… so basically when i turn the car on a cold start I hear a loud rattling towards the front of the engine. It only lasts for 1-2 seconds and then it’s ok, no sounds during driving. If I turn the engine off then back on the car is ok. However, this seems to happen randomly but always on a cold start.

In my experience, worn/slack timing chains get noisier on a warm engine when they expand slightly and the oil thins down slightly. More noticeable at idle.

Where does the rattle come from in an amplifier?

I spent a few hours sitting at the back of the amplifier, strumming chords trying to identify where the rattle was coming from. It seemed to centre around the power valves (also known as tubes) that hang behind the steel cage at the back of the amp.

What kind of Speaker rattles with low notes?

The speaker will rattle right from the first note. The rattle doesn’t change with time. The rattle is more present with low notes, so I used a flatwound strung bass, boosted lows and cut highs and mids. The recorder is a Zoom H2. It captures the rattle quite realistically I’m not planning on replacing the speaker.
