b_have Posted April 29, 2008 Share Posted April 29, 2008 Noticed that my powersteering on the auto is much lighter than the manual.Is there any electronic control within the system? Maybe linked to speed sensors? Works fine, just a little heavy compared. Any ideas? Link to comment Share on other sites More sharing options...
michael Posted April 29, 2008 Share Posted April 29, 2008 Could be as a result of a delimiter - I seem to recall some of them don't do the job as well as others to the steering doesn't adjust as the speeds increase. Link to comment Share on other sites More sharing options...

Why T Posted April 29, 2008 Share Posted April 29, 2008 yea mine is the same, alot hevier than my old auto tt????? Link to comment Share on other sites More sharing options...
SteveR Posted April 29, 2008 Share Posted April 29, 2008 The power steering is speed sensitive. heavy steering at low/no speed would indicate a fault, to me. Light steering at speed would indicate a crummy kph->mph conversion. Link to comment Share on other sites More sharing options...
b_have Posted April 29, 2008 Author Share Posted April 29, 2008 Excellent, anyone have a schematic of the workings? I'm guessing there is an electronic bypass valve in the rack? Link to comment Share on other sites More sharing options...
kieren1234 Posted April 29, 2008 Share Posted April 29, 2008 I would like to see a schematic of the power steering unit and system as mine has completely stopped working too. Link to comment Share on other sites More sharing options...

Mike M Posted April 29, 2008 Share Posted April 29, 2008 that's a great diagram, need to go and check mine now since I never really trusted the garage that sold me the car to have done this properly plus my cruise wont work over 70.

4packet Posted April 30, 2008 Share Posted April 30, 2008 My steering used to be overly light. Traced it to a km->mls converter fitted at the output of the gearbox. You need to make sure the signal to the steering is 1:1, otherwise the rack provides too much assistance. You either need to T a wire before the converter or fit a TRL type device which provides you with a 1:1 output as well. Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 30, 2008 Share Posted April 30, 2008 Just a simple solenoid valve in the rack, it could be *uggered, disconnected, or getting a corrupted signal. Easy to test though. They often suffer from people forgetting to re connect them after an engine out jobbie. Link to comment Share on other sites More sharing options...

Cheers Mike Since mine was delimited, my cruise hasn't worked at all! I would like it working again though TBH. Steering's fine though. Link to comment Share on other sites More sharing options...

paul mac Posted April 30, 2008 Share Posted April 30, 2008 one of the first jobs i did about 8 years when i got the supe was fit a speed delimiter from a company called "Far east services" i think, it came with some instructions but when i fitted as per their instructions the cruise would still not work over 70 and as i later found out the car was twitchy as hell at speed and bordered on dangerous to be honest, it was a case of re-routing the speed signal and all was well, i made a drawing which i could post if anyone has one of these units fitted Link to comment Share on other sites More sharing options...
tango Posted May 7, 2008 Share Posted May 7, 2008 I have the trl convertor on my tt, steering was well on low speed, but only when in higher speed, say above 100, it is feel a bit on the light side, is there anything I can do to make it feel not as light? cheers Link to comment Share on other sites More sharing options...

Are you sure it's fitted correctly because it shouldn't be light at speed as the Thor unit SHOULD be wired in to send an unmolested speed signal to the power steering.
