Hello there,
Can any body offer any advice. I bought my A2 1.6 FSI two weeks ago and I am on my second tank of Shell Optimax but the
car does not seem to be pulling away very smooth. It is abit like driving a Diesel turbo when there is a turbo lag. The first week everything was fine but now I seem to be suffering with this lag in the initial pulling off from traffic lights and from stop.

Has anybody else had this. The car will be two years old in november and has only covered 17,500 miles. It is 500 miles off needing a service.
Thank you
 
I know exactly what you mean. Its probably a combination of needing a service and the weather !

Our car had a spell of poor running in the extreme heat last year. The effect was making the car hard to get away from a standstill - as if you'd left the handbrake on. It also came back much faster after its recent service. 2 years is a long time to go without a service in my opinion.

Get it booked in and mention the poor running.

I find exactly the same when there is a combination of hot weather and i have the climate control switched on. My car has only recently had its service too.

Thanks for the advice and replying to me.
I am going to book it in for a service.

I was abit worried that there may be something wrong with the car.

The hot weather and using the air cond. all seem to tally.
 
Don't forget that FSI technology is very similar to diesel, so you do experience similar running. Plus if this is the first time the car has run on Optimax (or any super unleaded) then your machine will take a little getting used to it.

And a service will help.

I think this is a serious problem. I am on my second A2 in the past 6 months. We rejected our first A2 because we experienced two fuel leaks, but the car also had this uneven acceleration. It is very unsafe at roundabouts, because when you do decide to press the accelerator and go, the car does not move immediately, but moves about a second later, and then it does not move smoothly. Our new A2, only a few days old, has the same problem. It can't need a service already surely. I will try to see if the problem is alleviated by shutting off the air conditioning, but would like to hear of any one else with this problem.
 
Every car i have driven with air con seem to take power from the engine - i think this is common - maybe more obvious in a small engined car?!

A heavy right foot or beads of sweat is the answer ;o)

I think I've read somewhere that our A2's are smart enough to temporarily disengage the CC when doing full acceleration.

Seems reasonable to me, since I've never felt any difference between driving with or without aircon (thus ECON on).
And believe me, I'm keen on feeling a difference. Tried it for longer periods.
In my previous car (Honda Civic 1.4) I could very distinctively feel a difference in pulling power when switching off the aircon! But not in the A2.

As Steve says, this is a characteristic of the FSI engine, at low revs it is tuned for economy, at high revs it is tuned for performance.

There are archived topics which explain this.

10 Years ago my fathers Volvo 740 turbo diesel behaved the same way - worst diesel I have ever driven!

Off topic I know but....Ian, drive the Volvo S40 TD for comparison to your fathers 740. The S40 has the worst turbo lag I have even seen, bordering on being dangerous I'd say.
Back on topic.....how much power do people theink the A/C takes from the FSI engine?

Welcome. Sorry it's not on better terms!
The FSI does need a fair few revs to get it going-many drivers will say this. What fuel are you running-normal unleaded or super/optimax etc?
Maybe you can learn to live with it?
I now drive a Corolla with VVTi-I had to learn to rev the sphericals off it to get a decent get-away, but it does move when you ask it to!

Thank you to everyone who has replied. I have tried giving it a few more revs, and it does seem to be a bit better. Since we are still on our original tank of petrol, I don't know what it is currently running on. I don't know if the dealer would have put in Optimax. However, I will be putting in Optimax at our next fill-up, and let you know how we get on over the next 2 weeks.

I am also investigating the contribution of the climate control. Thanks again everyone.
 
Thank you to ianjohnsonws14 for this link. This is all very informative.

I have a Polo 1.4SE FSI, and have covered 11,000 miles in 18 months from new and have been using Shell Optimax since the car's second week of ownership.

On 'normal' unleaded' the performance was lacking, but with Optimax the car feels like it's got an extra 200cc under the bonnet.

Even with the climate at full blast on hot summer days, I've never experienced any negative impact on the car's power or acceleration.

I'm very pleased with the FSI engine.
