Hi my audi A6 has just come up with the servo restricted warning. I contacted my local plymouth audi who quoted 150 GBP just to plug it in. I have got a local garage to look at it. Plugged it in and have found no fault with the brakes, just the pressure sensor. Now I am really worried that I may face a bigger bill. Is the part available to fit by independent garages? Why such a high price for diagnostics when it took minutes?  Does anyone know the part number for an A6 oris it thesame as an A4?

Car is 4years old and only done 10,000miles.

To answer why it's so expensive.. it's just an easy way to make big money.. most people all just pay it thinking yes Audi knows best.  Exploitation is what I call it.  

No idea if it's the same part number.. you can just call the parts department and buy the sensor for your car.  Nothing wrong with that.  I'm guessing it will be in the same place.  Worst case scenario is you have to go to a garage and ask.. surely won't be as much as Audi.  Heck be nice to the guy in the parts dept and he'll be able to tell you where it goes from their parts diagrams.

Yep, it took literally a minute to unplug the old one and replace with the new one. All the warnings have gone off and the brake feels normal again. 
 

Thanks mate.. legend!!

My local Audi said £170 just to diagnose the fault!  And the car had only been out of warranty a month! 

Part is £70+vat from TPS.. hope this fixes it.

Hi Simon.. can you take a pic of what it looks like and where exactly you found it? 

Will help myself and a lot of folks here loads!

Cheers.
