Engine Blipping.

[Batman]

I'm Batman.

My TT seems to be losing power momentarily as I drive along these days. It's not long, seems to be about a 5 second blip each day or so.

I'd like to mention that it's not seriously worrying me yet but even so, if there's a problem with it I'd rather nip it in the bud and get back to worry free TT motoring.

It helps to be able to rely on your motor when you're me ;)

Hi Bats.

I've tried Googling the problem but sadly I haven't had much luck. So I'm going to have to take a guess. When I was a kid we had two cars that used to do it. It would always do it at about two minutes into the journey and apparently it was the engine reaching its optimum operating temperature or something on those lines.

So far as I can tell it's nothing to worry about unless if somebody else here has a different theory.

Glen.

Have you got a little more detail on your TT Batman? (model year, engine code, S-tronic or manual, FWD or quattro, Coupe or Roadster etc). Cheers, Tech.

[Batman]

Sure Tech, 2007, not sure on engine code, manual, quattro and roadster. Engine type is the 3.2 litre V6 VR6 engine that I have.

I would guess at maybe the fuel pump starting to go or fuel filter perhaps, but thats just a hunch.

[Tech]

Hmm, the 3.2 is normally a really strong engine and doesn't usually have many problems. There has been a few instances of bad connections at the throttle body caused by movement of the connector pins but usually this would bring the EPC light on straight away. I have seen cases of faulty fuel pumps (G6) which can occasionally leave one or two spiral shaped peices of swarf in the bottom of the tank (not on all cases), however this normally happens only when the car has about 1/4 of a tank of fuel or less left. Have you tried filling the tank with a decent quality fuel (i.e. BP/Shell etc rather than 'supermarket' fuel)?

The fuel filter is fitted for life and does not have a recommended replacement interval, although if you do find traces of swarf, you might want to consider replacing it. I doubt however, that a blocked filter would cause these symptoms, it would more likely cause a sensation of hesitation under full throttle.

I'd read that the 3.2 is a strong reliable engine myself but I know nothing's bulletproof (mechanically speaking). I'm getting it checked into a nearby Audi specialist soon and I've written down what you said so that they can check it. Taking it in as I don't trust myself to do it personally.

Best get it checked in case it turns into a bigger problem in the future.

Thanks to you all for helping, anything goes missing in your house and the worlds greatest detective is right here !
