I have an A3 2.0 TDi auto and am suffering the same hhc problem,

The car does not have the electronic parking brake, but does have the awful hhc system,

I have spoken to both the supplying Audi dealer and an independent and they are both hiding behind the same 'its working to spec and you cannot remove it',

However I have discovered if you take out the main fuse under the bonnet (No 25 a 40amp one) that governs the abs pump then the hhc does bnot work anymore - downside is that neither does the abs and you get the annoying lights on the dashboard....

I therefore conclude that there must be a switch somewhere or at least a wore that can be removed to disable this awful thing......

A wiring diagram for the abs pump would be useful, i'm looking around for one

 

Did tou find out what was wrong with your car as it was not handling hills?Mine does the same.


QUOTE=fshizzlemynizzle;1216928]I'm joining this forum b/c I'm getting super frustrated with Audi. So last year I noticed that my car would start abruptly from standstill whenever I drive up this particularly steep road near my office. I've taken it to an Audi dealership 5 times now to no avail and even have a pending lemon law case now. I'd like to make other people aware of the problem and I'd love it if you could test it on your car if you live near a steep hill. Please respond to this thread and even report it to Audi if you've got the fortitude to deal with them stonewalling you.

So technically, Audi is saying the hill holder "feature" engages whenever you stop on a steep hill. Apparently it's "designed" so that the hill holder grabs the brakes and then the transmission goes into neutral. When you go from brake to gas, the transmission then goes into gear and you're off. All good in theory. So in real life, the problem is my car starts abruptly with a small grinding/slipping noise every time I stop/go on a steep hill. There's a lag and the transmission doesn't engage quickly enough to prevent an abrupt start. It kinda slips and then bang engages. You would think it should start smoothly which is what you would expect out of a semi-luxury car. In 20+ yrs of owning European cars (1-Saab, 3-BMW, 2-Porsche, 1-MB), I've never had a single car do this so it is definitely not normal.

So Audi's response to my problem is that there's nothing wrong with it. They say it's performing according to manufactured specifications and that they will do nothing about it. Even this morning I took my car in to replace the sunroof motor and they refused even to document my hill holder complaint again b/c Audi says nothing is wrong with it and they can't keep documenting my complaint. My lemon law hearing is later this year and along with my other problems (steering shudder at low speeds-fixed, faulty sunroof-fix today, cold stalling due to a megatronic unit falling off inside the transmission-fixed) I'm hoping Audi will do right and take back my car.

Sincerest apologies for the lengthy post, but I really needed to vent. Please test your car and report back to this forum. Even my loaner car today as the same problem so I suspect every person on this A4 B8 forum has it as well.[/QUOTE]

 

I have a steep hill bear my home that I need to drive up daily. Car always has an abrupt start and once stalled. Anyone have a fix?

I live in a valley, am nervous about driving out of it.
