New Polo problems - Register

[Casper]

Just picked up a new Polo GTI last week, currently experiencing a growling/whining sound when the air conditioner is on. It only occurs between 1-1500 rpm though. Anyone else experience this as well?

Sure it's not the supercharger? Loved the whine of the Golf 118TSI I test drove before buying the Polo...

My Polo does have Hill Assist though. But as far as I am aware this is only designed to work from stopping you rolling backwards while in D or S, not rolling forwards when you are in R.

The situation I was in was quite precarious as I had both a car in front and behind me and made it very tricky to apply the right amount of throttle when reversing without it:
A: taking off and hitting the car behind
B: rolling forwards and hitting the car in front

If it does have Hill Assist, then maybe you ought to check with the dealer since some of the other guys replied saying Hill Assist works for them in R, D and S.

That's a pretty tricky situation, but you should be able to get out of it with a little patience. As I suggested in my previous post, apply the handbrake with the gear in R. Slowly release the brake and you should be able to feel the car creep backwards in this case (cos you're reversing), otherwise, lightly press the accelerator pedal til you feel a slight creep backwards. Then gradually release the handbrake til the car starts moving slowly. You can use the handbrake to control the movement, and adjust the pressure on the accelerator pedal accordingly.

Maybe you can practice getting used to the feel when there aren't any cars around. After awhile, you should get the hang of it. It's very much like driving a manual, it's just that the clutch plates engage when you take your foot off the brake pedal and not the clutch pedal, so it gives you slightly less control. Having said that, I just have to add that DSG is King! Hope this helps.

As a follow up to my problem...

I took it out yesterday to fully test it. First I went to the local shopping centre carpark that has moderate inclined ramps. I faced the car down the ramp, stopped it, put on the handbrake, selected reverse, took off handbrake and the car stayed in the same spot then after the 1.5 secs it automatically went backwards with no throttle applied at all. This suggested that the ramp was not that steep if the idle throttle was able to ride it backwards. Interestingly, for the first time I also noticed that when the hillstart assist kicks in you can hear a very faint high pitched beep for the duration of the hillstart effect. I did not notice this on the fateful day of my first interaction with the reversing issue.
Anyway, after realising that the ramp I tested it on was not as steep as the one I had my accident on I took it to another carpark where they had a very steep ramp. Same process, but this time after the hillstart kicked in and the 1.5 secs expired it did roll forward as the idle throttle was not strong enough for the steep decline of the ramp.

So this just leads me to believe that on that day of the accident it just failed to kick in. In hindsight I suppose I should have just turned off the ignition and started again, but I can definitely say that I did nothing different this time than when I had the accident.

very odd

I wish it was, but it's an annoying high pitched buzz. Only occurs when the A/C is on so I'm thinking it may be the compressor.

Yeah, definitely noticing that high pitched noise when you take your foot off the Brake.

I'm a new VW owner. I bought a bog standard (no options) GTI a few weeks ago. Overall, I love it. It's such a fun little car.

Unfortunately, last night I experienced my first significant problem with it. I was driving home in heavy, stop-start traffic and about 30 mins into the trip it overheated. I had to pull over, open the hood and let it cool down for a while. The rest of the trip home was without problem. There was far less traffic and the engine sat on 90 degrees the rest of the trip.

I haven't checked my fan yet. (I was too relieved at getting home without serious failure). Is that the likely problem?

Update: I just took it for a short run in reasonably high temperatures (it got up to 42 out my way) without any problem. I checked the fan when I got home. It seemed to be working normally at idle. My guess is that yeseterday it was sucking up the hot exhaust of the cars in front and that's what got it too hot. Hopefully, I won't ever experience it again.

Thanks for sharing.
I wondered if a supercharger and turbocharger in a tightly compacted engine bay would stress temp levels in heavy traffic.
I know it was a scorcher of a day + aircon running and no air flow but I guess the other cars around you managed ok.

Thermo fan(s) should have kicked in to prevent overheating though, I'd be taking it back and getting the fans looked at, a brand new car shouldn't overheat in that situation, not even on a 40+ degree day....

even my old 14yr old corolla doesnt overheat in peak traffic lol.. take it back to the dealer and tell them about the problem.

Coolant level ok?

The twin-charged engines have a rather complex cooling system, and air pockets particularly in the water/air intercooler can cause some overheating concerns if the coolant hasn't been sufficiently burped. My bet is, the dealership will burp the last of the air bubbles out, and be done with it.

Thanks for the responses.

Yep the coolent level is okay. I haven't had any problems since the one I mentioned. Given the responses, I'll take it in soon to have it looked at.

Polo 77TSI Manual owner, less than 1000km on the clock. Car today started making really loud ticking noises when idling, gets worse when applying brakes which is kind of strange. With the bonnet up, handbrake applied, and watching while someone else applies the brakes, the engine moves a lot and there seems to be quite a few parts rattling was unable to pinpoint what was making the exact noise I could hear from inside.

Unfortunately the service centre is closed until Monday so don't really know what to do till then.

My car has done nearly 15k now, I was driving along Toorak Rd today, I noticed the stereo cut out for a second, and then the steering lock came on. Really fun when driving along to not be able to steer correctly.

Had to pull over and turn car off then back on. Hasn't happened again.

Oh and a couple of weeks ago the car stalled at the lights. Strange for a DSG

A number of pages back, it was mentioned that there are some known rattles in the engine bay of the new Polo. Some include the fuel line ducting under the brake master cylinder, an aircon hose on the inner side of the right hand chassis rail, and washer hoses inside the rearmost cavity of the bonnet. Hope this helps.

Loss of power (electrics) could be caused by a few things. Best to book it in, have it looked over.

As for the stalling, there's a re-flash of the engine control module out now, that resolves this.

[JexL]

does that re-flash also apply to manuals? mines done the random stall once as well
