New Polo problems - Register

**MrMeaner** · 01-02-2011, 08:34 AM

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.
