Hi,
I’ve been having intermittent issues with my A6 for about 6 months now. Currently have 100k on the clock.
I’ve had battery replaced, area under scuttle cover cleaned out and I still have issues.
The symptom I am getting is the sensation at motorway speeds of a feeling like the brakes are being applied for a second and then released, but only intermittently and only during/after heavy rain. I also see a significant reduction in fuel economy (circa 10mpg).
It has become apparent since we have had a decent dry spell of weather and the issues went, but came back after heavy rain yesterday/last night.
I’ve rescanned with Carista and there are no codes showing, but consistent throughout is that when scanning the various ECU’s I always see on the “steering angle” - ECU not present.
I’m wondering if there is something strange going on with the ABS/steering system that could be causing ESP to kick in when in cruise control?
I’ve spent a fortune on this and as the issue is hard to replicate on a test drive, many garages are just shrugging their shoulders.
Any advice/views would be welcome.
Cheers
