Ok guys, I just got back home from the A.S.S., unfortunately my car has not!
As always they could not find out the exact cause of the issue, and I don't blame them since it's pretty hard to single out an issue without in-depth look into the possible causes. To add to the difficulty, the ECU scan showed no issues.
A guy drove my car (pretty sedately), no issues noted. Then he asked me to get behind the wheels. I tried my usual stunts to replicate the issue, still no signs. I also told him about the gear shifting inducing jerk most of the time and the same happened when he was driving too, he claimed it's there for all Figos and Fiestas, I agreed and didn't question more.
Then on getting back to the A.S.S the car was taken for ECU scanning. I was near the computer when the readings were shown. Of the 4 injectors, on idle, the pressure of one was more compared to other, while on applying the throttle, all the 4 showed a similar reading (reading of 1 i guess). The S.E. told me that is how it should be, so that too not an issue. No other problems or error codes were generated in the scan report
He asked the guy who drove my car to check the fuel line and he came back with some sample on his palm and on smelling it he said it smelled a lot of kerosene. I too took a whiff and it did smell somewhere like kerosene, I'm not sure if that is actually how diesel should smell. I know petrol does not.
The S.E. asked the guy to check some "coupler" which I don't know what. That was said to be just fine, after checking. The S.E. then came to me and said it could be a problem with the fuel contamination. So he suggested emptying the tank, cleaning it and the the fuel lines, and may be changing the fuel filter, fuel-up from a different pump and try. He mentioned that I would need to be paying for the fuel filter (1,300/-?). I was standing a little doubtful and I checked with him if that would be covered under warranty, to which he explained that since it's not a manufacturing issue, the customer will have to pay for it. I also checked if there is any cleaning procedure available for the fuel filter, but he said such a thing does not exist, only replacement is usually done. He told they could just shake off the fuel caught in the filter and that's the only cleaning that they could do.
After that he left for some urgent work. I stood there for close to half an hour more and then I called up the guy who test drove my car and asked him what steps they are planning. He said they have reported this to Ford India and is waiting for the reply. I don't know if that was true or just a misunderstanding. I was also told in between that they would check the fuel sample for possible contamination. At present I don't know if they will work as the S.E. told or if they'll wait for Ford to respond.
According to the S.E., the issue is clearly not with the fuel pump or the injectors clogging since he says the car will show far more issues if that was the case. No idea now as to what the cause would be. Anyways waiting for their call, which most probably would not come, I will try calling them up later and check about the status.

Now that I see it as a common problem, I will try to replicate this and report back. Seems like the Fuel System is not able to supply the correct fuel amount when the engine is on high rev due to down shift but the throttle is at zero position. Just My Thoughts. |
Yes man, seems to be a similar issue I am facing here. How many times have you faced the issue and did it all happen while downshifting attempt and pressing the clutch?

Hi Mustang, thanks for the explanation, seems to make proper sense.
As written above, took the car to the F.A.S.S. and the S.E. is sure that it's not the problem with the pump since that would show much more issues like mising, jerky ride etc.

Sorry man, seems like I missed your post. What you said makes perfect sense but I don't think that could be an issue with my car here. I haven't actually noticed the rpm going down that rapidly. If that was the case, then there should be higher frequency to this issue, but it happens very very rarely. Thanks for the inputs, will double check to make sure
