Grating noise
Hi,
My A4 2k has started making a grating noise from about where the exhaust cat is situated, the noise is only present when i start from cold, the noise dissapears after about 2 mins, any ideas?? Thanks. |

Need more information: What engine / transmission? Does it make the sound when moving and in gear? Does it vary with engine speed? Noise when brading? What speeds does it seem worse? Any error codes? |

Sorry for lack of info...... Its a 1.8 se manual, the noise is only there at start up from cold, dissapears after a couple of mins driving, there is no noise after that, drives well, no noise when braking or anything else, only at start up. Sounds like a "rattling / grating" noise. then dissapears when engine warmed up. also no error codes. HTH. |

Could also be the insides of the cat doing the same - rattling until it expands. The heat sheild is easy to check, just see if it moves around when cold. If it is the inside of the cat coming apart, I would assume that you'll see a Check Engine Light soon, as it will clog the exhaust system. Dan D '04 A4 1.8Tq MT-6 Central NJ USA |
