That's exactly what I had but without the heavy steering. :) Definite crab walk. Happens at higher speeds like 80km/h and you need to steer into it and if slow down quick a flick out of it. I recently had work done on the suspension but the steering wheel is not that straight after the alignment and wondered if that had anything to do with it...? Speedo cable is all good.

well if the steering wheel isn't straight that'll be your problem. there are two sensors up in on the steering column that tell the HICAS ecu that you are turning the steering wheel and which way. if your traveling along at at higher speeds, when HICAS becomes active, and because your steering wheel isn't straight the steering sensor is registering that you are turning the steering wheel, even though you really aren't, it will make the HICAS start steering. if your ok to do it yourself just pop the steering wheel off and line it up straight, or just take it back to the place that did the alignment and tell them to sort it out.

Having a think the sensors aren't in the wheel itself, so the wheel could be on upside down and it wouldn't effect anything. Looks like I'll have to lock up the HICAS.

correct the sensors are mounted to the steering column and the steering wheel boss activates the sensors when you turn the wheel. you should be able to slide the whole steering wheel boss off and jump it over a spline. it will require a fair bit of persuasion to get it off though.

Okay, sweet. Thanks again Josh.

if you havent removed a steering wheel before, be VERY careful and dont remove the nut completely before you attempt to remove the wheel. leave it on a few turns so it doesnt smack you in the face when youre wiggling it off!

Thing is, if the steering wheel wasn't removed immediately prior to this issue, it can't have moved on the spline.

Removing the wheel and re-orienting it will not correct the original source of the problem.

The rack centre position could be offset to one side, causing your problem.

You should turn the wheel from centre to lock in each direction counting the number of turns, if it is unequal in either direction, any adjustment should be made at the rack ends with the rack centred.

Then you can be sure that your rack (and therefore) steering column and wheel are centred correctly.

Good luck.

what work did you have done to the suspension? height adjustment by any chance?

Hahaha I've done it a couple of times so won't have that problem!

Great post, thanks for that.

might also been the rack bushes too! if they are stuffed, it will cause the rack to move also. its possible its just jammed in the wrong position.

I only just had them done. If some things weren't done correctly can that lead to these issues?

Bilstien coilovers, cambers kits and traction rods and all sorts of random shit. I really don't know a whole lot about suspension sorry. :( But definitely height has changed, it's certainly lower.

open your eyes before your mouth please

pull ur head in smartass, i was making a valid point about a possible scenario. which has nobody has proven otherwise or posted anything to the contrary. its entirely possible that if the front washed out on turn in, that the rear turning away from the corner could turn you off the road/track. maybe not a common situation but possible none the less.

      The best part of my setup is, we only have two sites. Our head office where I'd put every thing has plenty of internet capacity. We're on a 200/200 dedicated fibre. Even better, there's only like 6 people in the office at most, and the other office has 2 people in it (likely 3 soon). The majority of our work is in a custom piece of software, as it is part of the backend of the system we provide to customers. For our arrangement, on prem would be wayyyyy easier, and a VPN tunnel site to site is easy for me to manage. Scaled at many many sites, or quite a few hundred employees it's starts getting a bit different for all people outside the head office. However, everything in the cloud becomes worse for the people who operated previously at the site that held the servers, as now they're at the mercy of their internet, and not GBPS internal network (f**k the idiots who hook a desktop PC up on WiFi or permanently sit at a desk using a laptop and don't go remotely with it).   It really does come down to the business needs and structure as to what is best. For us, 365 is mainly being moved to for office apps, moving email from Google to Exchange, and setting up "Active directory". Otherwise we have a ticketing system with support that runs on our own cloud system, or the sales process sits in a CRM we pay for. My biggest push back for having most of the shit turned off and saying no when people want new shiney things is "that won't meet our security requirements, or efficiency gains, so all you're requesting is money spend to open us up to security issues, or to make our staff less efficient" Which is funny when one of our core values is "To do more, with less"

      Think of it as a fancy iFrame with the auth passed through to PowerBI as you're already authenticated logged into Teams   I'm the complete opposite, I hate everything on Prem, it's slow as shit, you need VPNs to get anything happening, then when you want on-prem DBs to talk to say PowerBI you need to install/setup data gateways to essentially VPN back into your SQL instance. I suppose from my perspective, on-prem sucks, but from an infrastructure perspective, your environment is somewhat air gapped to the web via your firewall(s), etc.   The curse of knowledge, the more you know the more you suffer. Farken philosophical shit.

      Wherever you ask them to. I had one added to the crossover pipe near the BOV as well as the hot and cold sides of the intercooler piping to provide greatest flexibility in measuring temperatures post-turbo. I have the IAT installed in one, and bungs in the other two.
