Had a very weird thing happen today.

 

Driving home on a near straight road,my steering wheel points dead ahead and car tracks in a straight line.

 

After about a mile I notice the steering wheel starting to go off centre, car still going straight, after about another half a mile the steering wheel had turned to the left by about two inches, yet the car was still going dead straight and not pulling to either side.

 

I came to a roundabout, went round it onto another straight and steering had returned to normal but then the same thing happened and kept returning all the way home.

 

I haven't got a ****ing clue what's going on, anyone else have a clue? I can only guess at something power steering related.

 

Cheers,

Daz.

Sounds like an issue with the hi cas, i take it its a TT

Yeah mate it's a TT.

 

How would I go about checking the HICAS out?

 

Thought I was going crazy at first!

Check the steering rack bushes, did a tech thread some years back how when these wear out the rack can slip left and right instead of turning the wheels and hence the straight ahead position changes, after turning it fully one way it will slip back to the right place.

Mmmmm, Mine has been showing similar symptoms. Looks like I will be checking my steering rack bushes at the weekend.

What should I be looking for? Cracking? Bulging etc'? will there be obvious signs of movement, like polishing effect close to the bushes?

Going through the service history every bush on the car has been replaced, rack bushes changed August 2009 and 9000 miles ago, rack feels solid as well.l

Did you get a pry bar in there to check for movement?

The passenger side is very easy to get at, so it's worth un bolting the bracket and taking the bush out for inspection. Must warn you tho' the drivers side is one of the most annoying jobs you will ever have to do on the zed, unless the engine is out..

They are all still like new mate, look like they have just come out the factory.

 

Was in at them with the bar but as I said solid.

Don't know then bud, after what Jeff had said it did seem like the rack bushes but if they're ok then it must be somewhere else..

I'm thinking HICAS now, was having a look online at the HICAS diagnostics, will give them a try if the rain ever goes bloody off lol.

Have been trying to get the HICAS into diagnostic mode wtih zero success.

 

Have watched a few youtube videos and it seems straight forward enough, but just can't get the Zed to do it.

 

Is there any other way via software even to check the HICAS?

If you have conzult it can put the HICAS into diagnostic mode. Haven't used it myself as I've ditched it.

 

HTH

Where can I acquire conzult?

Would that fact that my car was an auto but has been converted to manual have any bearing on my struggle to get it into diagnostic mode?

Anyone?

It shouldn't do but can't really help more than that mate. Sorry..
