Mikej100 Posted September 5, 2017 Share Posted September 5, 2017 Guys... My wifes '05 1.6 Fiesta TDCI has developed a strange whooshing noise coming from the exhaust when revved to over 2k rpm. It started a few months ago then went away but returned today. I had it on the ramp and have checked all the usual suspects intercooler pipes etc but can find nothing. Any suggestions? TIA Mike Sorry chaps just noticed i posted this in the Focus forum...its an age thing. Quote Link to comment Share on other sites More sharing options...

Battersea418 Posted September 6, 2017 Share Posted September 6, 2017 Had a similar issue, and turned out to be Catalytic Converter. Emissions test/reading on next mot? Quote Link to comment Share on other sites More sharing options...
Mikej100 Posted September 10, 2017 Author Share Posted September 10, 2017 Thanks Tony, You may a have point there as i notice a lot of exhaust fumes around the car but wouldn't i see a lose in power and possibly a warning light on the dash?

The cat on a diesel serves very little purpose, and is unlikely to be monitored by the ECU in any way. So it should have no effect on driving or on warning lamps. An exhaust leak will fail an MoT if they detect it. Quote Link to comment Share on other sites More sharing options...
Mikej100 Posted September 11, 2017 Author Share Posted September 11, 2017 Spoke to a very well respected local diesel specialist who along with his colleague both diagnosed a faulty exhaust center section not resonating properly. Its a cheap after market section that i had fitted earlier this year. Apparently if it was the cat that was breaking up it would amplify any noise coming from the turbo.
