Tick tock Gallardo?

[Beaver]

Weird, very weird.

My car was making a tick tock sound every second or so from the transmission tunnel. Could physically feel a vibration thru the tunnel, handbrake and gearlever. It's loud enough to be obvious.

Symptom exists at idle in neutral, and I think under power too, although hard to tell. Any ideas?

Ta.

Mine does this too, and has done from new. LHW said it is normal, although I am still not sure what "it" is!

Kind regards

Not to alarm you, but I had a very similar sound when my clutch decided to give up!

If I had my hand on the gear knob I could feel it ticking and tocking as regular as a clock!

Not sure I'd describe it as a vibration - it is a repeating "click" that can be heard when at rest and felt through the transmission tunnel. Frequency as Beaver said about 1-2 hertz.

Still, this thread has prompted me to ask Lambo B'ham when it goes in for some other work soon.

Kind regards

I don't think they can be related - as posted earlier, this tick has been present in my car from new, and its now done 15,000 miles and the clutch is less than 40% worn.

Kind regards

Hope it's not the clutch - seems like any fault with the G is likely to be the clutch!

It needs to go in soon anyway so I'll find out more then.

Not saying it is....just saying I had a "similar" sound.....

Good luck either way mate.....

Perhaps not, but I think the implied possibility of a connection in your post was clear...I was just putting forward evidence that such a possible link was not my experience, to avoid Beaver getting too concerned.

Anyhow, happy to be corrected.

If it's what I think it is, it's some pump which is part of the aircon switching on/off/on/off/on
Happens on every Gallardo I've been in - some more noticable than others
Very "cleverly" the Italians put it right under the hand brake

[Beaver]

Hmm. Thing is today is the first time I've heard/felt it..

Problem is that once you notice it for the first time, you will forever notice it
Ask one of the dealer tech guys - I'm sure this is the issue

[felix66]

as Traxx says and to put you all out of your misery........ its the air con. switch it off and the noise goes!

its a known fault and there is no fix so I'm afraid you have to live with it. later models(not sure what MY as mine is an 04) have it sorted by rerouting the valve that is opening/pulsing that sits in the transmission tunnel.

If you can deal with the temp without AC you will be able to enjoy the fantastic sound of the V10 to its full.

OK, will experiment tomorrow but I think that's put my mind at rest...

Thanks again

As Doug and Paul say, it's the aircon. Some cars are more affected than others. Appartently, it's a supply pipe mounted to the inside of the transmission tunnel, that 'pulses' giving a ticking noise.

There isn't anything you can do about, though I've heard of a couple of attempts to isolate it that haven't worked.

I just live with it and take it as a characteristic of the car. A heartbeat, if you will.

Thanks PH Lambo engineers - correct diagnosis!

Noise goes with aircon off, and the clutch works just fine!

[ted 191]

Thank fluck for that

[jonny5]

thanks for pointing this out, I only just noticed it :angry:

[Beaver]

Car is back from Lambo London - the knocking noise from the air-con pump is down to the air-con needing regassing.

All fine now.

[Beaver]

..except its not. Still ticking :-(
