Hi all,

I have a 07 Gallardo Spyder and recently the following light has intermittently been coming up on the dash when driving. If I stop the car, keys out and start again it stays off but sometimes will come back on again. I think its something to do with the traction control / steering? I have plugged a fault code reader in and nothing appears. The only other thing I have noticed that may be completely un-related is that the steering wheel has a bit of movement in it before I can feel the wheels turning (as in turn slightly to left or right, feels kinda loose), not sure if this is a characteristic of the car as I have not long owned it and came out of a 3 year old S63 coupe. I've tried various sequences to see if I can trigger it but no luck.

Note it did have new 'steering gear' fitted by Lamborghini in September 2018, about 1000 miles ago.



Can anyone offer some advice / pointers?

Thanks

Dont' worry : It's ESP off.
I Always drive this way : ESP off and Sport mode :)

To Switch it on or off just push for 3 seconds the ESF button.
See the pic (it's not my car but it's here).

I don't think it will be that as it switches itself on intermittently? Speed sensor/ABS sensor related?

Mine currently is showing the Stability control and ABS. I just a few minutes ago tried to read the code with a Bluedriver reader but it didn't pull the codes.

I figure mine is a wheel speed sensor or a wire to the sensor since sometimes it does work fine with no lights. I just need a way to know which wheel it is.

Yours with no ABS like mine on would mean yours isn't a wheel speed sensor. It could be a steering position sensor, especially if it has had the steering replaced they might have messed up a sensor or the wires. If you already have slack in the steering that isn't good. My car has over 63k miles and no slack in the steering.

Ok thanks, with the slack i just get a bit of play before I feel the wheels turning, not sure if its good or bad, surely if the steering gear was replaced it would have been sorted or worst still not put back together correctly? Are their any guides to check this over that you are aware of or is it main dealer only?

Like yours it flickered once but comes on so intermittently it could be a faulty wire. Do I not have ABS then?

You may still have ABS since the light isn't on, to me that would rule out a wheel speed sensor. Did you get some type of warranty with the repair? I would at least call them and explain the situation. There should not be any slack the system and slack could throw off the steering sensor.

The slack is what has got me thinking that. It was the previous owner that had the steering gear done (albeit at a Lamborghini dealer), back in 2018 though. Although having said that if I sharply move the steering wheel whilst driving slowly it seems fine, it seems to be happening more over bumps which could be pointing to a broken wire perhaps... I suppose it depends what the 'steering gear' actually consists of, the repair cost was over £4000 (GBP)....

I think it needs the correct diagnostics tool to be plugged in, unsure of the name of it....

Steering gear is the steering rack. Not a common thing to wear out in cars. I have multiple cars, one at 220k miles, one a 160k miles and the Gallardo at 63k miles and none have any steering play.

The feel from the wheel when moving feels like where the column attaches to the rack. Do they have a bush or something that attaches them both, that could potentially be worn? Wonder if there is some sort of workshop manual available.....

I never have seen the Gallardo setup and even when I changed my battery a few weeks ago I didn't even look at the steering rack since it is a non issue on mine. Most systems have a soft coupling to help keep drive train vibrations out of the steering wheel, this is also where it could have been disconnected when they changed the steering rack. I have had to replace these on old cars I owned from the 60s not in any newer car. It really is hard to diagnose your issue without looking at the car. But regardless you should feel no slop/slack.

Agreed I think this may be the issue (with the steering anyway), think i'll start taking apart tomorrow to investigate, i've found a workshop manual just need to find the correct pages now (its 1400 pages!)!

Thanks

Well I managed to get under the car and have a look today at the steering rack, I was quite shocked! The fitting that attaches the rack to the chassis rail was loose on the drivers side (passenger side in USA!). Feels like a clamp that the rack goes through then the clamp bolts down through the chassis rail. It literally has about 8mm of movement. As mentioned the rack was replaced by a Lamborghini main dealer in September 2018 (around 1000 miles ago) but not sure if a phone call to them would make them fix it give it was 18 months ago.....

Does anyone have a guide how to get to the steering rack mounts so I can see if its possible to do myself?

Well at least you found your issue. So the bolts are gone? I would call the Lamborghini dealer they should honor this. If not call the Main Lamborghini number. I had an issue when mine had a recall done and a call to Lamborghini USA got the issue fixed.

The bolts seem ok, both sides were just loose although right hand ones super loose (about 5mm of movement). Bolts seem ok so have tightened both and will monitor. Was going to locktight but a local specialist I spoke to advised against it.

I have sorted the light issue as well, I actually had a puncture on the rear left tyre, pressure was low, pumped up to 32psi and it went back down to 15psi overnight. Two new rear Pirelli's ordered today!

Nothing wrong with using loctite. Just don't use the permanent kind, there is more than one level of loctite. Also don't always trust mechanics.... mechanics are who didn't put the rack back correctly.

The specialist I spoke to said it was more than likely human error as he had neve heard of this happening before. Lets see and hope he is right! I have ordered some Sealey stud lock so will stick some on the thread when it arrives, besides, I have no intention of removing the rack again in the time I own it!
