Mechanical sound after cold start

[evgeni432]

Hi,

i have noticed a problem in my new ibiza 09 Sc 1.6 petrol manual.

after a cold start/ after engine was turned off for a long time, when i put in the first gear and drive a few meters (till engine hit 2/2.5 RPM, 18-20 kph) i hear a short mechanical sound, it appears to come from the engine compartment. the wired thing is that it only sounds once ofter the starting of the engine and afterwards its all fine. can any body explain?

and another thing, some tgimes the first gear and the reverse don't quite engage smoothly, the first gear appears to hit a "wall" like thing, some times i give it a small shake and it fits, appears only when gearbox isn't warm yet, (few minutes after start) then every thing is normal.

any ideas? should i visit the service station?

car did 2000 km.

I have noticed the first problem in my Fr. I think it is the turbo and it is not a problem, maybe just a safety feature because the car is too cold.

well, yesterday we had MINUS 15 degrees here in Bulgaria. I went downm turned the key and - the engine started easily (viva la SEAT)!!

What I found strange is there was a little noise that I hear everytime when the car is cold! When I press the clutch - it dissapear...may be it is the oil(still freezed) or something else....but...I also have an extra additional sound when the weather is cold (in the morning). My car is 25 000 km (almost) so I can say I know how does it normally sound!

Cheers!

Well its not the turbo that for sure

Its about 17 degrees in Israel (above 0), i didn't mean literally "cold".
this sound reminds me the sound that the AC on older cars does when you press the internal circulation button, but more mechanical and louder, seems to be electrically powered like a motor or a bulkhead of some kind... any body knows what I'm talking about?

and the gear box...

Could be an engine?

Think that's the gearbox oil but I'm not 100%. I had the same problem on my previous car and they said they could change it and it would stop the whining, but I chose to put up with it.

Thats exactly what i hear. I could hear it even in the summer so it has nothing to do with external temperature but with engine temperature. It is normal.

 

[Sinan]

yea. Noisy starts took my attention too. After engine gets hot enough the noise turns back to normal. Even the weather was around 25 C it was making that noise.

 

[techie]

Two things that cause the noise (or noises I have heard anyhow)

1) The ABS pump does a small pulse on start up, its a self test and normal

2) If you have a DSG gearbox the vacuum pump at the front left of the engine bay (as you look at it) charges the vacuum system so you have servo assistance for the brakes.

But I do not understand why when I press the clutch the sound dissappear..If I keep it pressed it is ok, when I release it I can hear it.

Anyway, it dissapear in few seconds (minute something)...

What do you think - do the guys in the dealer service will laugh if I ask them if there is a problem?

Best regards

some tgimes the first gear and the reverse don't quite engage smoothly, the first gear appears to hit a "wall" like thing, some times i give it a small shake and it fits, appears only when gearbox isn't warm yet, (few minutes after start) then every thing is normal.

i have had a similar thing with reverse and was going to take it to get looked at in the new year. mine is the same it is as if it is hitting a wall, although i cant wiggle it to get it to go in. i find that if i lift the cluch up slightly and give a very small rev it just pops in. if i take the cluch off and on a few times it makes no difference, it still wont go in. any thoughts?

I know what your talking about, like a metallic high pitch sound, that disappears when you press the clutch, it's like there is a metallic tube vibrating in the engine compartment.
I didn't go to the service with it yet but some one told me it's the flywheel.

tomorrow i will try to go to the service, i will ask them a few questions about it and other problems.
like creaking dash... damn, i love the car but it is so disappointing some times.

 

[techie]

Could be a clutch pipe touching the body somewhere.

 

[evgeni432]

Visited the dealer few days ago, appears to bee no problem with clutch, the boot handle was found faulty & ordered new one. Couldn't fined the reason for the creaking behind the dash (just behind the steering wheel/dials. tried to tie loose wiring but nothing helped, the sound is experienced when i press the gas on low gear (when the chassis flexes a bit) and resembles plastics creaking. any body has an idea? may bee the steering column?

help plz...

 

[vtxracer]

Is it a rattling noise and appears when accelerating ? If yes, i had the same problem. It was the A/C pipe touching the frame.

 

[evgeni432]

It is a kind of rattle but plastic like, when i press the gas (rapidly, just a quick press and release) i hear: tick tick tick or click click click and thats it. not when i brake, only accelerate or it happens when i operate the clutch (exactly at the moment you press the gas). basically it happens when the chassis is flexed during the acceleration or the brief pulling force of the wheels/engine foreword. (when you feel the car is initially accelerating, and you get that initial thrust).

it is really hard to explain especially when English is not my native language

Hi I have a 1.2 Ibiza and my reverse and 1 fail to engage sometimes, i took it into seat and they said they couldnt find a problem with it, just my luck, it doesnt play up at the stealers grrr.... so i just put up with it now, its not often, just occasionally, maybe once or twice a week, but its random, so i cant make it happen :=(

i had the same problem, but it gets less with time, i think its just the gearbox breaking in, and if you notice it happens only when the engine is cold (gearbox fluid).

 

[nightflight]

yeah, my first gear is occasionally difficult to engage but it's getting better as it gears worn in a bit, some times it'll slot straight in really nicely.
Same with second at times it'll be a right bitch, usually when i really don't want it to be both are getting better though

 

[bigman75]

I experienced the same with 1st gear. I've never had a problem with reverse. Now after 6k + miles it's very smooth. I'm sure it will improve
