So the 280 is now 10 years old with 56k and everything works at it should. It passed the MOT yesterday. Three advisories; 1. The rear pads are low. Knew they are. 2. Front tyres under inflated; they weren’t - 2.6 bar on both and 3. The Oil level is at minimum: err, nope. It’s just below maximum. Brilliant!

How can this be? My 2016 280 has 55k and it’s still has at least 5k miles on the front and rear pads; the discs are almost unmarked.

Works perfectly on our 2016 (oh wow - it’s 10 years old!!) 280!

When it stays on, is it switched to the Auto setting? If so, can you try turning it to manual when you do the procedure you mentioned and see if that allows you to control it manually? I’m not absolutely certain, but I think I read the heating / AC unit in the dash is fully self contained, so if there is an issue with the control system, that has to be changed. However, that might be subconsciously invented and therefore complete boolocks!

In the U.K., they’re not and an MOT failure.

Have you had an ABS or battery failure? I’ve had both and I can tell you, they do give all the warnings shown in this thread.

Yes. Can I suggest you get the car scanned by a reputable VAG specialist, cos they’ll have the equipment and, more importantly, lots of grey hair to identify these issues….

Then that could be your issue.

I can’t access the imgur link. Can I ask where are you located? Does your vehicle model have the correct hardware to enable the lane assist function? If it does, where did you obtain the coding? Are you using a genuine Rosstech VCDS cable?

Hmmmm… well, OK, albeit they’re not OE. I’d like to see them fitted and working.

Can I ask; who changed the all the ABS sensors? The reason is that I find it strange that the symptoms you’re experiencing are identical to many others who’ve commented - including ours too and in these cases it was found to be a failed (yep, the NSR) ABS sensor. The fault is intermittent; in our case it first occurred departing a ferry in NI. It repeated itself 1/2 dozen times on the 100 mile drive to our destination but then didn’t do it again for a couple of days. It went on like that for the rest of the stay, but on the trip home on the M6/40/25, it did it countless times.

Also, IMO the available Chinese aftermarket “dynamic” door mirror units are terrible and AFAIK, there are no OE offerings.

I got the cheap ones from eBay or Ali - can’t remember which - about four years ago and they fit perfectly.

Sawtoothing on rear tyres?

Ta. I’ll check mine in that case. Good excuse anyway as I’ve just finished whizzing up my VCDS laptop, a Dell E6410 with a 1tb SSD, upgraded to 8gb RAM and a fresh install of genuine Win 10 Pro. Total cost was £68. Absolutely flies now. Used to take 4 mins to boot, now it’s 35 seconds. VCDS takes about 10 secs to load.

Incidentally, does one get a dash warning to say the sensor has failed? If no, how does one know it’s failed?

You could get a one from Autodoc which is more than 1/2 the SUK price.

Just washed it. What helps is the Raceglaze water filter which means zero water marks, although I do towel most of it off. It really needs a whole day spent on it but I just don’t have the time at the moment.

Yeah, that's where it always blocks. I've tried using a cut-down cable tie and a pipe cleaner in the past but neither of those worked in my case. I really don't get why they couldn't use a 90 degree curved piece.

I’ve had and, like many others, continue to have this issue occasionally. I really couldn’t contemplate dismantling (and possibly damaging) the hatch trim to get at the pipework so on the advice of my service specialist, I now use a piece of thin welding rod and that always unblocks it. It’s a useless design IMO and one used on many VAG products.

Did the same trip yesterday. Nothing. Engine sound perfectly normal. Oil temp upto 110c. Weird….

Yep, could be Travs.

On Saturday, I had to travel from Surbiton to Ealing Broadway, a round trip of around 18 miles with a stationary hour of so before returning. It was stop/start and slow moving traffic all the way in both directions. On the return journey, I noticed that the engine it developed a constant chattering sound, not unlike the tappet sound of the old A series when they're out of clearance. On revving the engine in N, the sound remained, although perhaps not quite as loud as when its under load. The oil temp was between 103-105c and the water temp was dead centre as usual. The following morning the sound had gone, albeit the trip I did, didn't even get the oil temp beyond 70c. So it'll have to go in for a check up, but in the meantime, any suggestions?

It’d need to be scanned to confirm of course.

…..and it could well be the ABS sensor as @Berisford said…
