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!

Hi Steve, I shall try that in the morning. Obviously, not many miles done in the last 12 months, so to have a warped disk is alarming to say the least. I have put my hand near both wheels after a drive, and nothing untoward heatwise, and it doesn't judder all the time - that's why I thought stuck pistons... However, I'll get back once I've tried your suggestion tomorrow. Thanks

Update... From speaking to a mechanic friend up in Glasgow, he wagers, though cannot check until it's up on a lift, that it's the caliper. He says he had a very similar experience with an A4. Although counter-intuitive, it ended up being the caliper. We've worked though everything and Occam's Razor...it seems to be the cause: 1. Intermittent juddering when braking (from front left wheel) 2. This was happening last year, and went when new disks/shoes were fitted. (same side) 3. Owl-like long hoot/howl from same wheel when driving slowly, goes when you just touch the brake as softly as possible. It all makes some sense, as the noise is definitely a resonation. Now, I would have thought the mechanic who did the front disks would have looked at the caliper, but... So, advice here from members is - new calipers or rebuild kit. And if new calipers - I was looking at TRW. T

I couldn't find a way, so I'm listening too...

I have 84k on mine, and am not worried about that amount. Obviously there is the quantum leap of 100k, but that's all in the mind...I keep telling myself.

Hi Tony, Yes it is. I have a £5/month Giffgaff card in mine. Rubbish 3G, and now that Google Earth is no longer supported, it's £5 a month I could spend on beer.

You can do it with ODBEleven. https://www.facebook.com/watch/?v=801754323980315 Best buy I have made for the car. Diagnosed so much stuff with it.

I've had bearing replaced, but mechanic says he doesn't know if it's fixed. He thinks he heard it again on a test run. I haven't heard it, though granted I've not driven much. So it's a waiting game. A £149 waiting game ! 🙂

Yep. Google stopped supporting third party stuff via google earth.

If I drive for a while - home to Glasgow (100 miles) or two days ago, home to Melrose (35 miles), I notice a humming or low woo sound (sorry no recording), from the passenger wheel area when turning right or driving along a road that goes even slightly right. It stops when I touch the brake pedal. It is definitely something in motion that is making the noise. This time, when I was on a road that was going slightly right, it also came on with a pulsing hum. Any ideas? It's going to the local garage when there is a space - hopefully to go on a lift and get an inspection - but I thought I'd ask the hive mind first...mainly to get an idae of what is might be and get ready for cost!

I meant Goodyear Eagles. Duh.

Ok, just driven around Scotland from the Borders to John o'Groats, round to Tongue, down to Ullapool, through Glencoe and back through the Trossachs. Sitting on zoom meetings was doing my head in. So I just took off for three days. Some wonderful roads, some not as much. And too many caravans and camper vans. However... I have my MOT in Wednesday and the tyres seem fine, but I am sure they will need changing this side of new year. What recommendations does anyone have? I have Michelin Pilots on at the mo, but thinking of going to the Bridgestone Eagle asymmetric. Just for the tiny MPG increase. Potenzas? I used to have those on my TVR
