Mark chapman Posted August 8, 2021 Share Posted August 8, 2021 I have an audi a3 1.6 tdi 2010. Noticed when I accelerate I can hear a slight clunking noise? This is weird because it never did it before I had the clutch master cylinder changed. The mechanic said that I have a noisy engine and shouldn't worry about? Can anyone help please?

Magnet Posted August 9, 2021 Share Posted August 9, 2021 Hello Mark, ’.....clutch master cylinder changed’ . Sure it was the master cylinder and not the slave cylinder/ release bearing assembly? Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
Mark chapman Posted August 9, 2021 Author Share Posted August 9, 2021 Yes it was definitely the clutch master cylinder. It was still the original audi one on the car. It recently had a new clutch and definitely. Quote Link to comment Share on other sites More sharing options...
Magnet Posted August 9, 2021 Share Posted August 9, 2021 Thanks Mark, So a clearer picture now emerges, and as well as a new clutch master cylinder being most recently fitted, the car was fitted with a replacement clutch assembly in recent times - including a dual mass flywheel? So the issue you have doesn’t necessarily mean that it’s anything to do with the fitting of the master cylinder, but could equally be to do with the clutch assembly itself, or indeed something totally different. Can you let us know why the master cylinder was changed? I’m sure you will appreciate Mark, that it would be extremely difficult to pinpoint a cause of this issue without actually inspecting and testing the car, so the answer is more likely to be found at your trusted local garage, otherwise it becomes a guessing game on here. Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
Mark chapman Posted August 9, 2021 Author Share Posted August 9, 2021 Hi Gareth. The clutch master cylinder was changed due to the clutch pedal hitting the floor and not coming up. The master cylinder had a crack in it and was squirting oil. That part of the car seems fine its just the rattling noise when I press the acceleration pedal that concerns me. The mechanic said its nothing to worry about and I have a noisy engine? I've never noticed the noise to be thst loud before? It's more of a rattling noise than anything else. Thanks.

Magnet Posted August 9, 2021 Share Posted August 9, 2021 Hello Mark, I would most definitely be seeking the opinion of another mechanic. Apologies for being pedantic but the noise has now changed from a clunk to a rattle. It could be me, but I interpreted the originally described symptom as a clunk on take up of the drive. A rattle on acceleration would need to be clarified to the inspecting mechanic as being a noise when the engine is revved when stationary, or only when the car is on the move. Perhaps you could let us know how you get on Mark. Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
