    (Relay of CRi pump OR relay of low pressure pump inside of fuel tank). Thanx in anticipation

    The bent rubber pipe behind intercooler just above engine protection plate and near catalytic convertor of turbo was changed.
    Relay of low pressure pump was changed.

    Okay, here's an update. For whatever reasons unknown to me, I haven't encountered the powerloss issue in the past 600kms or so. In the past year or so, I had drastically reduced the number of highway drives, as the issue kept cropping up at every 40-50 kms or so. Recently, I had made a few highway drives of about 100kms each without stopping and havent faced the issue even once on those test drives. I had complained to Fiat India many times and kept pressurizing them to send a team here. Now if they do send a team and the issue doesn't show up during the test drive, my complaint will lose credibility.
    The powerloss issue had tortured me for a whole year and nobody could diagnose it yet and now it suddenly vanishes without reason. Not sure whether I should be happy. My gut feeling says maybe it's just temporary. I am planning a 400km round-trip in the coming weekend. That should provide a better picture.

    Okay, I have had the long trip that i had mentioned in my earlier post. The powerloss issue didn't crop up even once. The issue seems to have resolved itself without any external corrective measure. It could be temporary but I am happy for now and also perplexed at the same time. The car felt beautiful during the long highway drive - had almost forgotten about this aspect of the car. Nevertheless, a big thumbs down to Fiat India for failing to provide support inspite of uncountable escalations during the past 16 months.

    Any solution for this issue in TJet?

    I and some others as well (see below link) have been facing some similar issues with the TJet

    http://www.teamfiat.co.in/engine-compartment/12095-possible-t-jet-acceleration-issue-causes-3.html

    While going through first 4 pages, it appears that symptons are similar:
    - loss of power after acceleration sometimes
    - increase in turbo lag at times i.e. turbo getting active from around 3000 rpm

    Above symptons are more present on a hot day i.e. when temperature is above 37-40 degrees and when AC is running. This problem started happening after car was serviced. As per FASS everything is fine - since the examiner does not show anything and they feel that acceleration is fine.

    Any pointers would be helpful - also if any solution in this thread that is applicable to TJet, please point to the same
