How did you get on mate?
I think I started tens if not hundreds of times on my red light (once my mechanic mate had confirmed the issue), and the guys at ECU testing sorted it.
Hope you got the same result
Hi everyone,
Been off here for ages, been away with work.
I’m really shocked to see so many with this issue. And even more shocked at Audi’s response. But then again, I’m not surprised!
Anyway, my issue persists. I’ve just accepted it for now; I don’t have the time, funds or inclination to...
Sorry, been off here for ages!
Car been back abs forward to garage, again!
Been lots of fun!
Very long story short, the new Master cylinder arrived and was fitted. But the juddery braking remained.
The mechanic spoke to Audi to try and figure the issue and it transpired that there’s been a run...
Sorry for late reply.
Car has been back and forward to the garage.
This issue has been traced to the master cylinder. The mechanic believes the issue is down to the brake fluid renewal process, whilst bleeding the brake system and brake pedal. We agreed that it was unlikely the abs unit...
I have EXACTLY the same issue. It’s off to the garage on Monday for diagnosis...but interested if anyone can shed any light on this.
Have tried lubricant on the pedal bushes etc, but no joy.
Easy to remove, I don’t really know. I’ve taken them off on older cars, but didn’t look into this time.
Yes the car needs to be off the road whilst it’s done.
My preference was to have a pro do it. It was ‘only’ a couple of hours labour for a garage to do it, them being the experts.
Seems like a recurring issue Audi need to solve!
Mine has recently been sorted by ECU testing. My local garage sorted the removal and replace. £420 all in.
Crap that we have to do it, but better than £2500+
Thanks Matt.
Just checked their website, and at the top of the A4 issues list is this one...

...so it seems like they’re on the ball with our issue!
Thanks Matt. A garage replaced my module and sorted everything they could.
Thanks for the info, I’ll give ECU testing a shout.
Do you have a reference or something that i could quote to help them understand my issue is the same as yours?
Thanks!
Hi Guys,
Catching up with this after busy few months.
So, I’ve had my module replaced, which solved the initial braking issue I had. The car now brakes witching normal operating parameters.
But, I still have the red warning and error in dash each time the car starts.
Matt - do I read this...
Hi Guys,
Sorry for late reply!
I haven’t had the unit fixed or replaced. So I’m getting the brakes warning every time the motor starts (inc start/stop!).
Has anyone progressed any further with this? Really really don’t want to have to come up with 3k to get it replaced.
Can units be re-coded...
So my issue was clarified; ABS pressure sensor was faulty. Changed quite easily apparently.
The knock on problem now is, the ABS pump has recorded some sort of failure due to this. And the only way this can be sorted is to replace the pump.
I’m trying to get a more technical explanation for the...
Hi,
Sorry to chip in...I’m having the same issue. Currently sorting with my 3rd party warranty company and Halfords (the authorised repairer).
Has this all been sorted? And how much is the cost?
Thanks
