tsk, no change in engine note. Another observation is when this happens, rmp meter does not cross more than 2500, does not matter how hard I press the accelerator.

Many thanks amitk26.. I could open the horn pad exactly as you said. However, I realized that the steering wheel needs to be detached in order to fix the 'horn ring' properly and this required a box spanner of the right size. Hence I took the vehicle to TASS; the advantage I had after the above exercise is that I could very specifically tell them the issue/ show the hanging part.

The mechanic at TASS took-out the steering wheel and showed me that the screws that retain the 'horn ring' were missing. The same was fixed with two screws and the horn started behaving right. I was out of TASS in an hour's time . Knowledge is power

If your engine note is not changing, and meter is showing 100, then meter is faulty.
When you cross 2500rpm i.e. rev hard then also, the meter is not showing anything but your rpm is higher.
Do you have OBD II dongle?
That will catch this issue

If you can get your vehicle to Noida I can diagnose it for you.
I bought mine for dx.com

Dear All,

I observed today that if I keep idling the RPM stays at around 800 but as I start driving and press the accelerator and RPM needle crosses 1500, it starts dropping after that and the meter starts showing the reading around 100 during idling after that.

Your RPM meter is definitely faulty. Strange case - RPM meters are quite reliable usually.

I have another strange case to mention. Occassionally, while using the handbrake for stopping during a drive (toll booth fee payment, for eg.), and then continuing with the drive after releasing it, the speedo doesnt go beyond 40kmph!

The solution for now is to park, apply and release handbrake. Definetely needs to be mentioned during the upcoming annual service.

I understand Indicas post 2004 had an acceleration sensor around the handbrake area. Perhaps Safari has a similar setup. Can experts please comment?

About the issue, it surfaced late last year or so,after the seats, upholstry, on the floor were removed in order to paint matte black anti corrosive paint.

We did a diagnostic today. Meter is faulty. For example, it started showing 2000rpm constant. Engine was revving normal, and we also confirmed the same via OBD II dongle.
Speaking of reliability, this is Tata .
My console was changed under warranty at 82000kms on the odo.

Default Steering "obstruction" problem

A problem as re-occurred.
Some time back, my Safari steering started jamming up a bit. While turning, esp when stationary, there was a point of "resistance".
Applying more force to steering wheel would allow the wheel to turn. It was bad with vehicle cold and lessened when vehicle warmed up.

I did not get to the bottom of this as the steering box developed a leak and had to be overhauled. Also changed the center pin.

Recently, the problems come back.
Esp while turning left, there is some sort of "resistance" at a point. Its bad when you just start driving, and gets "loosened" up.

What could be the cause? Its like some part gets stuck somewhere.
Before I hand her over for experimentation at the TASS, I need to get informed, so I can supervise the job, and get the exact problematic part changed.

Hmmm... Exactly the same thing I am noticing for the past few months. I though this was due to tyre pressure or a stone on the ground, especially while starting to roll, but never came back to it because while running everything is fine.

I am also getting large drops of oil (blackish, so I assumed it is engine oil) on the floor of my basement. Happens only if I drive for at least 30 minutes or so, but not if I have gone out for a short trip. Is it linked with the steering problem???

Power steering oil is not blackish. Do check the rod which connects the steering to the steering box. Any leakage around that area?

Thanks TSK for all the help, sorry for the late response, i was busy with work. Yes as confirmed by TSK, it was faulty meter and everything else was working as supposed to be.

The steering in Tata Safari is hydraulically assisted. There is an oil pump that provides the hydraulic pressure and a rotary valve that regulates the pressure depending on the amount of force exerted on the steering as sensed by a torsion sensor mechanism.

Some of these parts could malfunction and create the problem, which eases when the oil becomes less viscous. You can raise both front wheels and check steering operation.

Hope this is of some help.

Mohan.

I recently got the steering overhauled from ZF
This is a problem with the pump? Or could it be due to some other mechanical obstruction in the steering system?
