Audi A4 TPMS type - direct or indirect?

[french_audi]

Hi Folks,

I asked this question under the tyres section but had no replies.

I am pretty sure that new Audi cars use the indirect method to measure tyre pressure - that is ABS and wheel rotation method, rather than the in-valve sensors.

My new Allroad has been ordered but of course I can't confirm as I don't have the car yet. I wish to buy some winter wheels and tyres so I need to know before ordering.

Can someone with a new A4 confirm?

Regards

Mark

Havent got anything that new (2012 A6) but mine is via ABS. It could be they`re all the same?

Thanks to Alan for his sole reply - nobody else bothered....

I contacted Audi and they have confirmed that the Audi models use ABS sensors and wheel speed to monitor pressure.

So for anybody else curious or planning on Winter / wheels and tyres then they know they do not need to buy the pressure sensor valves. A lot has been said about this indirect method but I think it is perfectly fine, that and owner checks.

For anyone curious and after some research I chose Nokian WR D4 winter tyres. I saw that the Continental tyres were doing well but some reports were saying that the results were biased. Continental tyres are certainly very good of course.

Hi
Sorry for not replying. Yes no TPMS sensors on mine so assume it's ABS and rolling radius.

As for the winter tyres, my son has the Nokian WR D4 on a Fiesta and they seem great and are very well priced. They are super quiet too which I don't think is a feature of the Contis.

It does seem the Nokian are a good bit quieter and better on fuel economy. Most of the these Winter tyres do well on snow/slushy ice but sometimes cold rainy days are a difficult. The Nokian seem to be better in the rain and also last longer.

Thanks
