Tob

Hi All,<br><br>I finally got a chance to tow a trailer last week, and noticed that when pulling or decending hills (engine braking) it would make a steady &quot;farting / grinding&quot; sound. Kind of like air blowing out of a large balloon - inside of a metal can. Is that the normal? I don't think it was the clutch or tranny - but it was hard to tell. I am a little hesitant to tow anything else in case this is abnormal. I did some searches and all I could come up with was the Turbo Wastegate - whatever that is. <br><br>NO - I don't have an engine brake - not one on the vehicle spec sheet anyway.<br><br>No neutral rattle - in mine at 3000+ km<br><br>Many thanks in advance.

Yes it is the waste gate. The waste gate activates when there is too much pressure built up by the turbo. This can happen when you are accelerating then suddenly back off the throttle. The system no longer needs the extra boost pressure so the waste gate dumps the excess. I found this out when we went on a test tow with the service tech
