Rattling noise from the exhaust of my BMW 328i Hi everyone,
I needed some of you to weigh in on a a problem I'm facing with my BMW 328i. My car suddenly started making a rather loud rattling noise coming from the end of the exhaust pipe. The noise starts as soon as I start the engine, hot or cold, and continues while driving. It sounds exactly like this:
Thanks to the good folks of the world wide web, I figured out the problem. The noise is being caused by the exhaust flap. My car has an electronic flap within the exhaust pipe that opens and and closes depending whether the car is idling or being driven. As I understand, the actuator is broken, the flap has come loose and is making the rattling noise.
I went to the BMW service center and they identified the exact same problem. Their solution is to replace the entire exhaust set up which will cost me about 70k. Also, the part has to be imported from Germany and will take 3 weeks!!
I also went to a local workshop chain which goes by the name of GoMechanic ( https://gomechanic.in/luxury-car-enquiry/bmw). They claim to have experienced mechanics, well verse with German cars. They also identified the same problem and said they could cut open the exhaust pipe, fix the flap and weld it back. This is likely to cost about 10-12k. I am very apprehensive about having the exhaust pipe cut open.
Additionally, reading on the internet, it seems there is a cheap and easy fix by installing a new spring/ fixing bow ( https://parts.bmwnorthwest.com/p/BMW...307620323.html) and takes no more than 20 minutes.
I am afraid I am not receiving the most sound advice on this from the BMW workshop or this local workshop. I would really really appreciate if some of you could share some thoughts or suggest another mechanics/ workshop in South Delhi/ Gurgaon/ Noida where I can get some honest inputs.
Thanks a ton for reading and thank you in advance!
