I just paid for a new part loom for the abs stuff. 

I'll see what they come up with.

Just when I thought I'd coughed up enough for the car this month...

I have been having headlight etc stuff from a failed level sensor - however, the scan doesn't show which one - so - I bought 4 and the garage has kindly replaced them all. However, the error is still in the memory and the car has sunk at the front!

We are at a bit of a loss - they are going to clean up the old sensors and put them back on to see if it sorts out the level. But if not - it may be genuine audi parts are needed...(!!!! £££££££). Before then - any one got any ideas?

Hello guys! I own a Audi A6 2017 (67 plate) and i have some problems with it. The problem is when i turn right on the Dash comes out : Esc/abs: fault , hold assis unavailable, tyre pressure fault , audi adaptive light fault , brake servo system fault , hold assist unavailable , main beam unvailable. 
I went to the mechanic and put the tester on it and said about the Abs Module and Abs sensor. Ive change the sensor woth genuine part ( TPS UK ) and same problem…today i went and check it at electromecanic to see and he said their is the ball bearings wheel the magnet is not good anymore… ive change that also with genuine part (TPS UK ) and no results 😶

i put the tester again and gave me this errors: C101B14 and U111300 

to be honest im desperate as i dont know what it has. Can somebody who had the same problem can help me ? Please ! Thank you very much !

It is your ABS sensor - either the sensor itself or the ring. I've had this twice. The garage will want to change the entire bearing - that's up to you. Just had it fixed last week, and had it two years ago. It's VERY unlikely to be the battery.

I serviced mine a month ago. No issues. Pumped the oil out, 6litres, 5.5 in and dribble the rest. The mmi sensor thing has two stages it seems. Reading one, ignore...then 30 secs later a second reading. 

Sorry to hear about your sensor though. 

You can't fix it. Google withdrew support so it no longer works. 

Just a thought, does it occur only in certain car settings? Dynamic and Individual for instance? I have the 2013 BiTDi with 90k on the clock and never had anything like this.

It's gone. The annoying problem of the low speed owl-like howl and the brake judder after 30 miles or so. Go with your gut reaction...

Despite paying for a new bearing (it wasn't that) and the garage then ignoring me when I asked to change the caliper, I went to a new garage - supplied my own parts and he immediately noticed the caliper was rough. "I can rebuild it" he said in a Six-Million Dollar Man way - but as I'd bought a new caliper and new discs and pads - I just asked him to replace the lot. He did - £75!!! And now, no judder, no howl. Seems counter-intuitive that the howl would be the caliper, but a friend who works for the wonderful A for Audi in Glasgow, said he'd seen it before - that combined with the judder seemed to indicate caliper. 

So - shout out (as the youth say), to Border High Performance in Norham, Northumberland for the fitting and wonderful customer service, to MTEC Brakes for the lovely grooved discs and pads (no issues with these at all - properly bedded them in - lots of smoke, but a nice polymerised coating on the discs now) https://www.mtecbrakes.com/, and to Brakeparts (https://brakeparts.co.uk/) for the excellent caliper and phone chat. 

Looking forward to this years roadtrip. Will either go clockwise round Scotland, as opposed to anti-clockwise last year, or may see if we can travel to Ireland and have ten days there.

One for the archives this.

Yes indeed. I took the risk, and it was ok. But you do need the right files. 

I may, or may not have updated mine myself. The new forth road bridge and the new M8 interchange wasn't showing. 

The worst bit is the time and the fear you may brick your car. I didn't. 

The SD card is used for the upgrade. Audi will charge c. £300 for the update. You can do it yourself (disclaimer), at your own risk.

All sorted. Changed the caliper supplier, it will be here tomorrow.

New caliper on its way - but I need to travel a few hundred miles in the next week or so. I am thinking of getting the garage to do a rebuild until the new one arrives. Does anyone know what calipers are fitted as standard to the 1LL coded A6 C7? front passenger side.

There are options for the kits. 

It's a temporary fix - as the judder, the howl etc., has been diagnosed as caliper sticking slightly - 20c difference in disk temperatures after a 20 mile run (I knew that pizza oven laser thermometer had other uses!). So new caliper and some nice new pads and disks on their way.

At last. just the wee knocking noise on the drivers side rear to sort - worn bush I am hoping.

Worth buying the OBDEleven for this sort of code clearing.

https://obdeleven.com/en/

and I'm not on some sort of commission for mentioning it in all the posts!! It's just saved me a lot of money!

I don't think you can reset it with a fuse removal. You need to clear codes for it not to come on.

The extra performance of the 3L means you can zip past the 2L's 🙂

I just drove to Glasgow and back - a 200 mile round trip, though half of it on smaller roads - I averaged 42mpg. I have the BiTDi, 313hp 3.0l V6. I am very happy with that.

The OBD11 solved a problem that Audi Dealership in Glasgow spent ages NOT solving, but billing the vendor garage under warranty regardless.

It was the all lights on, ABS failure, all adaptive systems failure - I've posted about it before, but thousands were billed (not to me thankfully) and in the end the OBD found it to be corrosion in the GPS fin. It also solved my adaptive suspension fault - sensor off eBay £80, and fitted it myself.

Worth its weight in Bitcoin.

Yes...Adaptive Suspension

Good plan. But I haven't had a repeat this morning. I'll get some silicon spray and watch youtube vids!! 

On another note. That howl has gone since the new tyres and alignment done!

Thought I'd throw this one out before I go to bed, and see what is caught in the morn.

Just now, I had to drive to the local town and back, and I noticed - out of the blue that there was a creaking coming from the rear. Not there when i go over bumps, but more when I go over rises in the roads - more of a smooth bump - lots of those in the countryside here.

Any ideas, or should I tidy the boot and see if it is there?

But what could I DIY check for?

Thanks in advance, as ever.

I use the ODBEleven. It's been amazing. Saved me thousands. Literally! And you can do some simple recoding. 

I thought it may have been some limp mode kicking in. Are there no error codes at all?

It gets better...

Looking at my tyres I noticed more wear on the outside of the passenger side wheel - enough to get me a warning from the local constabulary, should I be stopped. So, I knew new tyres were due this year, I forked out on a full set of Michelin's (more later). While in the tyre depot, the owner checked out the bearing, and the caliper for play, he gave the whole thing a blast from the compressor too. No play on bearing, no tell-tale marks on the disk, no play in half-shaft - that he could see or feel.

New wheels on - drive home - c.20 miles. Decide to brake a lot and take corners 'well'. Then slowed down to 20 in the villages (it's the new speed limit in Borders - the Audi hates it!) and NO howl - 20 was the speed it usually kicked in at. To double check, I drove into England...to Berwick for my shopping. No howl in the town.

There is still a judder on braking though, so it was agreed by pal in Glasgow and at the tyre depot, that it could be uneven wear on the pads - the wheel alignment was out, and it's all corrected now. So we shall see. A set of pads is a lot cheaper than a caliper.

The tyres - I know I asked ages ago. I have Pirelli on when I got the car - but these Michelin Pilot Sport are excellent for noise and grip. Mainly a summer tyre it seems, but so far so good.

Let's wait and see if it's the pads then!

Easier to get a £20 magnetic mount for your phone than a £1.5k retrofit.

OK - drove for 4 miles and stopped. No heat at all on the disks. Continued to drive to Kelso, no problems - no judder on braking. All seemed fine.

Came back on more windy roads, brakes still ok - maybe I could feel something through the pedal, and then the howl came - though it's not a howl -it is like a very loud and long owl hoot. We tried to record it, but it's resonating through the car body and difficult to capture - though when she put her window down (we were in a v under an old railway, you could hear it outside. Then it went. It only occurs under 20 miles an hour.

When I got home - both disks were hot, as expected. There does seem to be more dust on the wheel on the passenger side one, and there are noticable lines on the disk. They weren't cheap disks...

I am going to have to keep on at my mechanic until he can get it on the lift, he's snowed under...

Will advise as I want to be able to drive a long distance when lockdown ends!
