Ok here is the video for all to believe that the car actually moves straight now.
Had a meeting at oberoi motors noida where all the attempts were made to sort out the problem but could not solve. Yesterday Mr. Rajgoplan GM of Oberai motors had called me to know how the problem has been sorted out I gave him a brief description he asked me to get the car for alignment checking so they can just be sure that nothing is abnormal.
I went there at 11.30 & met the Tata csm Ms Sumedha whom I asked if I can have the official version of the finding so we can conclude the matter but she too 1st wanted to know how the problem has been sorted out so I briefed her about the workshop & the method they used to find the faulty strut. I asked
her to accompany me on an official test drive so either we conclude that tata manza can drive straight or we conclude to their old stance that due to road camber manza will go straight for 20-30 mts only then will pull to left.
She suggested that before we move out on a test drive we should at least take the alignment reading on the same machine.
Car was taken to the platform reading taken Toe value showed out of the range, that confused her how can a car be moving straight if these values are out, so the car was taken off & reloaded on to the platform just to test the repeatability of the alignment machine, total 4 times this test was done & she
asked & even I wondered why is the machine not giving the same results every time the car is mounted on the platform.
The DET confirmed that slight variation will always be there but it should not go off the limits, I was surprised with this findings bcoz before 16th june this very alignment machine was checked for calibration & only then I took the car there as it was confirmed that the Alge alignment machine is now calibrated.
Is this a expected behiviour of a machine?
its like you measure 1 kg iron in Bangalore its 1kg & you measure the same 1kg iron in Jaipur it becomes 960gms then you measure the same 1kg iron in Delhi it becomes 1080gms. How could that be possible?
Now after being aware of alignmnet values out of range I took the tata team (Mr. Rajgoplan, Ms Sumedha, DET Oberai motors & myself) for a test drive, DET who has been attending the car started the drive & after 15kms he confirmed that yes the problem has been quite reduced & car fairly is moving
straight to quite some distance, I took over from there & then drove another 30 kms round trip from Pari chowk on greater noida expressway.
I drove at 80kmph car went almost straight on the road with slight left pull then we approached the speeds of 100-120 where I again pointed towards the steering left / right roll & then hit teh straight road patch starting from sector 93 car perfectly moved almost a km with 4 people loaded took the car to 120+kmph car moved straight but left pull becomes evident due to steering vibration.
Right before pari chowk almost 5kms road is perfect straight & had a best of the drive at 90-100kmph all were convinced that YES the manza can go straight & was quite evident to all of the tata members, remember they had witnessed the left pulling on the very same roads too.
I gave the car to Ms Sumedha so she herself can feel the straight driving & she drove at 80kmph & yes the car moved straight she felt the steering wobble at 100kmph but the DET says this is due to the roads & its normal I again disagree to this behaviour but I am ready to drive another 1000kms so the tyre can set according to the road camber then it might improve.
At last Mr Rajgoplan himself drove the car 80-100kmph & car remained straight in the lane they all agreed that in spite the toe in values shown out the car happily moves straight for quite a distance. Now the unanswered question remained that how is the car going straight when the values of toe in shows out?
We came back to the workshop & Mr. Rajgoplan said that the strut is not even covered under warranty, so how come the workshop changed it, none of the tata team present with me has ever heard of "Gurgaon Car scanners" they confirmed from me twice about the name & I then told them that best is to check the car history from their Tata CSM network, they took the printout & yes they got all the details of the work done at Gurgaon car scanners.
Not convinced with the alignment reports Ms Sumedha wanted to change it to default which I refused as of now & told here that let it run for another 1000kms then we will see if there is any abnormal tyre wear, her concern was exactly that if the report is showing it out it might create other problem later on hence she wanted to redo the alignment as per the recommended values, but as of now she took photos of the 4 tyre so we can match after 1000kms run.
The meeting remained inconclusive bcoz the test drive shows straight moving car (4 people tested) but alignment reports show toe in out of range, so how is then the car moving straight remains a mystery to them hence there is no official version from Tata motors to my question, "Can manza drive straight or not?"
Here are the 3 alignment reports can anyone find a fault in these numbers?
