Slight miss/hesitation and odd noise once switched off
« on: April 20, 2009, 09:43:25 pm »
OK, had bit of strange one today.

Car was slightly hesitant on the way home work tonight...felt like it was missing slightly at low revs in 4th (at a fraction under 30mph).

Got home, let the car idle for a minute and then switched off.  As I walked around the car I could hear a strange noise.  It was most noticeable on the drivers side of the car...as I stooped down by the petrol cap I could hear a "glugging" or "dripping" sound coming from what seemed to be the petrol tank area.

Is this likely to be a bit of trapped air ?  I fuelled up late yesterday and hadn't had this problem until today (damn BP cr*ppy petrol !).

Any thoughts ?

You do realize, Stealth wolf will not sleep tonight now and will be under his car as i post this.  :laugh:
I think you just thought it was to do with the juice, so you heard something in that area, that you would not normally be know where near.

I have heard this before something to do with pressure realise valve back to the fuel tank. Sounds like a glugging sound more then anything.I wouldn't worry Soundlab, sounds like the same thing.

Slight miss/hesitatation would be something else. Is your Car Remapped or stock?

It's completely stock.

It was audible enough that I managed to get a recording on to my phone of it ! lol !

Just seems a bit odd that the car was quite hesitant and then I had this noise 10 mins later.  I wouldn't be surprised if the hesitation is BP fuel related, my Skyline didn't like that stuff at all.  I only put the BP in as it was on the route home...

Nope, no warning lights, etc.  Everything else seems fine.

Just got slightly concerned when I heard this "glugging" sound after switching it all off.  As you say, could be a pressure release  valve or something like that.

You realise I have a fear of being trapped under a vehicle and refused to change rims without chocking the other three wheels and placing the removed wheel next to the jack should the jack fail?

I also had a mate bring an ambulance and a fire truck round so if anything did happen, I'd be taken to hospital fairly quickly.

Furthermore I took the liberty of texting the ITU consultant and telling him what I was about to do just so he'd know what injuries to expect. I also asked him to inform the Trauma and Orthopaedics registrar so he could prepare a theatre on standby.

I then had a thiry minute long chat with immediate family members and told them I loved them. I also told them where my will was and where I had buried the treasure.

That's why it was 3pm when I had started to change the wheels and ran out of daylight.

The GTI isn't just a machine. It's very much a living, breathing thing.

Also, soundlab if you listen closely, when you put the key in and turn it, just before starting the ignition, there's a whole load of noises coming from the engine bay.

There's also some funny noises when you turn the car off and a little red light flashes too.
