Yesterday I did Bangalore-Dharapuram-Bangalore at a single stretch to attend couple of my friends weddings. The round trip was around 900 kms
I was doing 120-130 constantly on GQ and the car was cruising effortlessly till the last 100 kms of the whole trip.
During the last 100 kms i felt something was stopping my car to move freely, I felt some sort of turbo lag when i tried to overtake a vehicle or when moving on some steep roads.
When i downshift and press the gas pedal to overtake, i felt my car is getting stained a lot to move forward loosing the actual turbo kick. I stopped my car for sometime and proceeded, the same happens again.

I did my 20k service in jan and now my car is running around 24k on odo.

I doubt the filters as it was not changed for last 13k kms, will check and change it this weekend if needed.
Do i have to check something else apart from filters?
Do i have to suspect the turbo?

I need advice from experts on the other things to be checked in this case to identify the problem and sort it out.

Change the air filter to see if there is a difference. If not it may require an EGR cleaning though its a little too early.

Looks like filter issue.

Are you sure its not bad fuel?

Air/fuel filter would have affected the entire trip; not just the last 100 kms.

Was the tyre pressure fine? Or as Dhanush suggests, something to do with fuel?

Since you say the problem cropped up during the last leg of your trip, something must've have been different then.

Nevertheless, 13k kms is a long time; do get the air/fuel filters changed. Hope all the oils were changed at the last service.

Its a good idea to get the turbo checked since the DDIS engine has a known issue of busted turbos if engine oil is over filled. Hopefully the issue might be something else and not the turbo, but your saying that you couldn't feel the turbo kick has got me thinking about this.

I will change the air filter and check, though it did not have any issue. It had done 13k already with it.

I doubt it was because of bad fuel as i felt the problem only at the last 100kms, it did effortlessly for the past 300 kms with the same fuel.

Tyre pressure was fine and kept it 32 PSI, I was also doubtful about the tyre pressure first and checked it to be fine.
Oils were changed in the last service, i checked it today morning and it is well above the minimum point. but too blackish, will change it if the service advicer suggests for it.

I will check the turbo also anyway, since i was facing this problem suddenly on the run.

It could be contaminated fuel. The impurities probably settled at the bottom and came up as the fuel in your tank lowered. This happens pretty commonly. The first step would be to refill at a good outlet and see if it makes a difference.

Do i have to flush the tank if this is the case ?
or getting it to just above empty and refilling should be fine ?

A small correction.

Its probably due to Bad fuel you face such issues. or mainly clogged air filters.

Also its best to get your Turbo checked, just in case, since Maruti's with DDiS engines are known for Turbo failures.

Start with checking the diesel filter. The residue left will give you an idea about contaminated fuel. After checking, make sure to REPLACE the filter.

If there are no issues there, then as sankar suggested, proceed with checking the turbo.

@BulZire

Please dont me for asking this, was it your HANDBRAKE??
Even partially pulled up Handbrake can cause it.

Were you experiencing the same only on higher gears? What happened when you went in neutral on high speeds, did you feel the same drag.

That way you can isolate if its engine/any other part like brakes/ball bearings etc.

[swiftnfurious]

Bulzire, were you able to do good speeds and was it just that you were not feeling the turbo spool? I have this problem in my Swift D where on long drives after almost 80% distance is covered, the car would suddenly lose it's turbo kick-in effect, but would cruise nicely to 100-120kmph speed. Overtaking also would not be as quick as it used to be. I guess its got more to do with the time the car has run in a single shot. And 13K kms for the airfilter is stretching it a too further. Please change it every 10K kms and I usually clean the filter every 3000 kms. And yes, its a good thing to check the oil spill into intercooler, the pick up gets sluggish if its there.

Thanks,I will check both the filters and change it anyway. Will check the turbo as well.

No, The handbrakes were off. I too checked it once i felt the lag.
I am facing it in higher gears only like, 3-4 & 4-5

I can do good speeds and no problem in that. i felt the lag only when i revive it hard to overtake or climb some steep.
Initially i was also suspecting that it is because of the long drive i did and the car is too much stressed. but i hope the problem was something different.

Anyway, I will take it to MASS and check the filters,turbo and intercooler. Is there any DYI on how to check the filters for impurities by myself.
Just to get something confirmed.

Cleaning the air filter is a very simple job.

1. There is a black rectangular box in the engine bay inside which the filter is housed.

2. And there is a bolt from this cover to the bonnet metal which you have to undo to release the top of the black box and then take out the filter.

3. Once you do it, you just need to tap it on some dust free surface [wall / floor] to get the dust out of the filter.

4. Once done, you could put it back in the box and tie the bolts.

If you have the right tools, this should not take more than 5-10 mins altogether.

If you have a MASS nearby, then you can take it there and they have a 5 point check which is 120/- where they check all the fluid levels and top it up and check for some electricals and all. This is what I usually do for every 3000 kms general check up.

What speeds do you do when you shift from gears 3-4-5!?
