POWER STEERING FAILURE
POWER STEERING FAILURE
STIFF STEERING / STEERING WHEEL STIFF
It was a perfect sunny day with hardly any breeze, when my wife and I decided to go for a Sunday outing. We loaded the VW Polo 2.0L Highline, with picnic umbrella, and packed a picnic basket filled with food and refreshments. I mounted the bicycle holder on the tow-bar ball and attached our 2 bicycles, and off we went. But our joyous mood was abruptly interrupted about halfway to our destination when the Polo had a sudden steering problem. This is probably the worst thing that can happen to any unsuspecting driver whilst driving in a relaxed state. As I was entering into a long but sharp curve, my power steering kinda «froze for a second» . I was steering with one hand — which is all it normally takes — because the steering wheel is so light. But before I could respond to grip the steering with two hands, I also instinctively braked and with screeching tyres, I hit the pavement so hard that both front airbags popped.
The steering wheel had suddenly become hard to turn / stiff and tight /difficult to turn. Kinda difficult to explain. A stiff hard to turn steering wheel as if there is no power steering. It was light to steer when suddenly it was hard to turn the steering wheel, because the steering wheel went stiff. A st iff steering when turning. The steering wheel becomes stiff and hard to turn. I hope you know what I mean. Fortunately there wasn’t a another car involved and even more fortunate nobody got injured except my pride. The first thing that went through my mind after calming the wife down and confirming that she was ok, was to determine the extent of the damage.
As the airbags deflated I looking at the dashboard and saw all the light on the dashboard glowing. The yellow EPC light was on, the yellow steering wheel light (K161) was on, the ABS světlo was on, the červená kontrolka baterie was on, and the yellow brake pad light was on. The engine had switched off and I realized the ignition was still on. So I tried started the engine and it wouldn’t take, I switch the ignition off and tried again, all the light went out and the car idled. On further inspection, I saw the r im that hit the curb was deformed and the tyre was flat. I figured I could just fit the spare and we would be on our way. As I reversed away from the pavement, the steering wheel was back to normal, it was light again. After fitting the spare wheel, I turned the steering wheel two full turns in either direction with one hand or rather my fingertips. This was very odd, even peculiar, because the Polo just came back from its 100k service / cam belt replacement a short while ago. I’m certain if there was any problem with my steering wheel my machy would have told me but he said absolutely nothing. Anyway, so we eventually get home and as I turned into my driveway the steering goes hard/stiff/difficult to turn once again. As I drove forward the steering wheel returned to normal. So I popped the bonnet, checking for anything out of the ordinary. I rolled under the Polo, checked the steering control module, looked at the steering pump (V187), yet it all checked out fine. Out came VCDS and I scanned the Polo and found the battery connection to be intermittent. Look at the 18010/P1602 error below.

Thereafter I decided I was going to take the Polo back on the road. So I reversed out of the driveway and suddenly the problem was back. The only thing I did was climb the 30 mm coping at the edge of the driveway so I drove back into the driveway and as the back wheels hit the driveway copping the steering was fine once more. Since the steering pump (V187) actually stops working for the second or so, it had to be something to do with the power. So I pulled on every visible cable that goes into the wiring harness to the steering pump (V187). I even checked the enclosed fuses on top of the battery when I noticed that the negative battery terminal wasn’t properly tightened. As I tightened the nut I discovered the nut was stripped and wouldn’t tighten any further. Then realized this had to be the problem. I scratched around in the garage, found a screw that would work, tightened the battery terminal and reversed out of the driveway and drove it back in a few times and the problem didn’t reoccur. So I called my wife and asked her move the steering wheel to and fro with her hand while standing outside the Polo with her hand through the open window. I loosened the battery terminal and disconnected the battery while the polo was idling. When it was disconnected my wife couldn’t move the steering wheel and when I replace the terminal she could. So I was totally convinced that the intermittent battery contact caused intermittent power to the pump which is exactly what happened a second before I fit the pavement.
So now I had to track down the cowboy who stripped by battery terminal nut because the last time I took the battery out to replace my headlight bulbs I personally tightened it and am darn sure it wasn’t stripped. This was roughly a week before it went for that major service. It just had to be one of the workshop guys that was responsible so like three days later I went to my VW /Audi machy’s workshop to complain and demanded compensation for the damage to my car but got the saddest news. The same Sunday that my wife and I want for our picnic my VW/Audi machy was out biking and was killed in a head-on collision and died on the spot.
Here are some VW, Audi power steering problems listed below, all of which seem to have a (G85) sensor issue.

When I surfed the net, I discovered that several other VW owners experience similar problems. Here a dude who says:- «The dealership keeps giving my car back to me unfixed yet still replacing parts! The dangerous part of this is the steering locks up when the car dies and i’ts still moving. I am fearful of driving it and I haven’t gotten anywhere with VW. I am not alone and that it seems to be the same particular year and engine as mine in most owners replies. I would like to help find a solution before any serious accidents happen or anyone is hurt. Thanks».
The Steering Angle Sensor (G85) is an opto coupler fitted in a collar under the steering wheel airbag. It sends sends the steering wheel position to the Power Steering Control Module ( J500) at the base of the steering column interfacing with the Electro-mechanical Power Steering Motor V187 all of which need power to operate properly. If the power disappears, the pump doesn’t work and the steering goes stiff until the power is restored.
steering wheel stiff, steering wheel stiff hard, Steering wheel hard to turn, steering wheel becomes stiff and hard to turn, steering is very tuff and its hard to turn, Steering stiff and hard to turn, Stiff Steering, stiff steering when turning, stiff hard steering, stiff hard steering wheel stiff and tight, hard to turn the steering wheel, hard to turn your steering wheel,

Can you please tell what exactly was the problem with steering. My GT TSI’s steering feels extremely hard sometimes. I keep checking tyres for a puncture every time i find the steering hard.
How old is the car and how many kilometers has it covered?
At 27k on the odo, I’d found that my car’s link rods and steering ball joints needed replacement. Plus, the Continental MC5 I was running at the time had gotten pretty hard. These factors contribute to a hard steering. Sometimes even the wrong tyre pressure could be the cause.
Post repair / replacement, the car feels brand new and the heaviness / tightness from the steering has disappeared entirely!

Hi sagpatel. The issue I was facing was a tak tak sound coming from the steering column while normal driving. It had run around 9k kms. The steering was not hard and the car was running stock tyres.

Re: Volkswagen Polo 1.2L GT TSI : Oficiální recenze
My first Polo had a known engine-bearing problem: fixed under warranty. Diagnosed and fixed by them, even though I thought it was suspension making the noise.
My current Polo had a known steering fault, fixed under warranty for its original owner.
I hate to think that VAG dealers might be like lawyers: It’s 95% that give the other 5% a bad name . It would seem that getting a good one is important. But I can report that I have not had any real problems with my VW after-sales service.

i keep tyre pressure at about 34 psi. But my problem is steering feels too hard and after a while it becomes normal. My car is 2017 oct manufactured registered in 2017 oct itself. Still running stock tyres and car has done about 18k kms.
Also one more problem that i face is DSG jerks from d3—>d2 and d2—>d1
Sometimes when in d2, there is kat kat sound and then car shifts to d1. upshifts are normal and quick.

Here’s what I would suggest: make a note of what rpms the jerky downshifts happen. Replicate the shifts in manual mode and check if the shifts are any different. My experience is limited, but I think it’s more to do with how the engine reacts on downshifts rather than the geerbox.
I vaguely remember reading on this thread that the sound is the first indication of an impending mechatronics failure. However, that’s an extreme scenario, not something you’d have to worry about now.

My friend in Hyderabad had a similar issue and service center told him that it was a problem with his steering rack. It was replaced under warranty. So you should get this checked by your service center.

Re: Volkswagen Polo 1.2L GT TSI : Oficiální recenze
Have had a good discussion on Tata Tiago JTP on it’s official review thread. It ended up more like Tiago vs GT TSI.
Did some meticulous digging on the reviews and found GT TSI to be mentioned as slower than the Tiago JTP in 0-100 kmph dash, albeit by few seconds only.
Most of the difference is been said to be because of the manual gear box of Tiago. Now if the Polo GT TSI is launched in manual mode and driven in Manual mode itself then will it be doing the 0-100 kmph run quicker?

It is 113 bhp of Tiago JTP vs. 103 bhp of GT TSI. GT TSI produces more torque (175 NM) than JTP (150 NM) though.

In real world comparison I seriously did not see it perform as mentioned on paper. May be because of the manual gear box and the way they have set up the rev limiter.
Polo is heavier than the JTP yet it feels nimble and quicker. The timings recorded say other wise albeit just a second or two slower than the JTP.

From the (short) test drives of 3 turbo petrols I did recently, Polo GT TSI has almost zero turbo lag (Hector and Seltos were the other 2) and that may be the reason it feels quicker. I read that the JTP has significant lag.

Yes the in gear acceleration is much better than JTP and also Abarth Punto. But that credit is more to the DSG than the engine. A lot was debated that Polo GT TSI is a good commuter than a hot hatch, to which I too agree. VW needs to improve on this, good all round disc brakes, better stiffer suspensions and importantly better sweet sounding exhaust.

IMHO, the gearbox does not play a role in in-gear acceleration, as there are no gear shifts involved. In-gear acceleration is to do with how wide the torque is available in the RPM band.
In the Tiago JTP, the max torque of 150Nm is available in the 2000-4000 RPM band. In the GT TSi, the max torque of 175Nm is available from 1500 to 4100RPM. As the max torque is available over a wider RPM band, TSI would have a better in-gear acceleration.

7 speed dsg is also a factor here.7 gears means shorter gear ratios for first few gears. Shorter gears will give better acceleration.

Thanks for pointing this. I had not thought about this factor. Gear ratio should also contribute to in-gear acceleration.

My TSI does not creep in D mode
My gym valet told me yesterday that I should get my car checked as it does not creep forward in D mode. This got me thinking and I realized this change in behavior since past 1 year or more. I clearly remember that GT creeps forward in D mode. But mine does not do that any longer. I don’t recall when this changed.
Is there something broken or worn out which is resulting in this? Or is it some simple ECU setting? I notice that in N, the rpm is about 800 which goes up to 1000 when I shift to D (without any physical movement on ground).
My GT TSI is nearing its 4th anniversary and have clocked 40000 km. I have been using it for sedate city driving for 99% of the mileage. Except for this no-creep observation (which doesn’t really affect driving), there hasn’t been a single issue with the engine or transmission. The car currently runs pretty smoothly and its as peppy as ever. I am wondering what could be wrong? The car is still under 2+2 warranty till Oct end and I intend to but the add on warranty every year till possible. Please suggest. Thanks.
