    Hi, just wondered if I could get some advice/thoughts for my Delta (2012 1.6 Multijet SR)  Please forgive me as I’m no mechanic so my description may be a little basic…

     

    Ive noticed that under normal acceleration she sometimes ‘jumps’, there’s a loss of power for a split second  at around 2000-2500 revs, normally in 2nd or 3rd  gear, when its happened with the window open Ive noticed the car makes a noise which sounds a bit like a mechanical cough of air. Ive also noticed that the rev counter doesn't drop down just stays in the same position

     

    At the moment it is periodic and seems to happen more when the car is warmed up, (it doesn’t happen under hard or gentle acceleration) it tends to happen about 1-2 times on a 20 miles (each way) commute, I wanted to let it develop a bit more before I took her to the garage so I could give them a definite description (plus my dealer is 30 miles away)  There are no faults coming up on the dashboard or lights and there appears to be no other running problems.

     

    many thanks :-)

     

    Disconnect the electrics your MAF (left of the turbo) and go for a short spin. I have tried this and the car worked great and seemed quicker and more responsive and the awful "darth vader" chatter off acceleration has gone. (further test to follow as I am going to leave it off for my home commute of 15 miles)

     

    At least that has proven there is an issue.

    It is now going in for an ERG clean and possible MAF replacement tomorrow.

  2. Hi Chris, I've had a look this evening, I think I've located it, and no it doesn't appear to be loose, I've checked the connectors etc. and all seem to be in order

    I have checked my pipes today and the pipe going into my turbo is not off but it is lose, I can't pull it off but can move it side to side about 1cm.

    But it looks like it has been like that for a bit as it has polished the metal on the connector on the turbo.

     

    If that likely my problem, is yours the same?

  3. Hi,

    I am getting an issue. Sounds like mechanical air escaping/ stick being dragged along the floor sound when coming off throttle mainly in 2nd, 3rd and 4th gears. Sometime I get a bit of breif drop in power accompanied with it, Just a split second.

    Garage have checked it and have said it is not the turbo and is a characteristic of the car, I am finding this hard to believe as it never did it a couple of months ago and seems to be getting more regular.

    It happens virtually all the time on soft acceleration (town driving) when the car is warm.

     

    Any ideas as it is doing my head in. :)
