Intermittent yellow coil flashing on dash..

Followers

October 13, 20214 yr

Hi all,

Have a 2014 A3 1.6TDI. Every now and again a flashing yellow coil like symbol comes on the dash. When it comes on it goes into limp mode, if i stop the car, turn the engine off wait a few moments start it back up its fine. It does it every now and again! Anyone had this before? There's no smell of burning turbo or anything like that. I suspected DPF? All my driving is town driving really.

Any advice is greatly appreciated!

On my A6 C7 the glow plug warning light flashing indicated that the Pre DPF temperature sensor was failing. Not saying it is the same for yours but....

The lamp is a common fault indicator and you need to get the codes read to pin point the fault.

If temp sensor then not critical when intermittent but will affect regen cycles long term resulting in possible future DPF blockage.

Engine / ECU to Injector wiring loom

Neil Robertson · 5 hours ago5 hr

Hi, I'm looking for a engine/injector wiring loom that goes from the ECU (8P0 907 115 T Med 9.1) to the injectors (06F906036A) for a Audi A3 2008 2.0L TFSI Quattro due to an intermittent misfire issue on cylinder no. 4. Cost from TPS for genuine replacement is astronomical, any help would be appreciated (e.g. where to source a replacement, correct part no., etc)

Are S5's notorious for not being serviced?

ZeroX · Saturday at 10:46 AM5 days

Hi, following on from my previous thread, I have seen another car that I was interested in: https://www.evanshalshaw.com/search/details/used/audi/a5/automatic-petrol-white-coupe/06ce9494-f94d-f111-8fdd-000d3a874790/ When I enquired with the dealer, they said there is only one stamp in the book from February of this year, and no history at all in the Audi database. So there is only evidence of 1 service in almost 10 years. I am starting to get a bit !Removed! off with this actually, and it's real

C5 RS6 034 strut top mount

petec5 · 18 hours ago18 hr

Hello all After a year of owning my first RS6 c5. It seems I'm in need of new strut top mounts. Do any of you have experience of the 034 rubber mounts? I've seen they are solid vs original ones that have bearings. How much of a difference does this make. And on a side note has anyone used RB Racing brake disc. What's your thoughts? Any help will be much appreciated Pete

Help with some issues

Kian · May 27May 27

Hello everyone, Wondering if anyone can help me. A few weeks ago my EPC light came on and immediately went into limp mode and started jumping when driving at 5mph. After a few hours I came back to the car and it was fine so I drove it to my storage unit. I came back the next day and when starting it the EPC light and EML light were illuminated and the idle was quite rough. I came back to it about a week ago and all the doors were locked, the key isn't unlocking it and the barrel of the central

Wing mirrors don't fold out when unlocking the car.

Wing mirrors don't fold out when unlocking the car.

john260164 · 12 hours ago12 hr

Hi. My partner's recently bought Q2 has an odd and not very welcome feature. The wing mirrors fold on locking the car with the key pilp, but don't unfold when the car is unlocked with the plip. They only do so when the key goes in the ignition. In some circumstances this can lead to doubt about whether the doors are locked or not whereas before it was obvious as the plip alone folded and unfolded the wing mirrors (as is does with my similarly new A3). The garage says it can't be changed but does

JGB · 16 hours ago16 hr

Hi all I have had my A3 since September 2025 and I haven't yet been able to figure how to park it in my garage with the brakes off. It's an auto and I have read lots of stuff but I cannot figure it out. I may be stupid but there you go any helpful advice will be appreciated. JB

A3 uncommanded engine shutdown

Bobs dad · 15 hours ago15 hr

I have a new A3 Black Edition auto. Within four weeks of delivery the engine cut out whilst driving, the drivetrain under positive power. The car rolled to a complete halt, the retardation entirely commensurate with the wheels driving a dead engine - it did not freewheel. The instrument panel remained powered and displayed no warning lights or fault messages. I shut the car down and after a pause restarted. Since then it has operated normally. The Distributor has found no data supporting t

Andy baggy · May 21May 21

Recently while driving my EPC light came on . Followed by my engine management light. Unfortunately I was on the motorway so put car into sports mode in the auto box to keep the revs high so I could get home the 49 miles. Been to the garage this morning no lights on my dash they diagnosed 2 coil packs going down. They are going to replace all 4 spark plugs and coil packs next week. They also said that I may now need a new catalytic converter. Has anyone had any issues with this sort of proble

A% front suspension groan

IainH · 11 hours ago11 hr

Last summer while in the heat of southern France, my A5 (Dec-2017, 40,000 mile) developed a front suspension creak. It was always at low speed and particularly when turning left. The car was completely checked on my return, 'shaked, rattled and rolled', but steadfastly refused to creak once, however, everything was checked, levered, put in a shaking plate, and no creaks or movement in joints found, and so while noisy, the car was declared 'good' (safe). The sound is very like the creak heard her

Lewbyleww · 18 hours ago18 hr

Hi all does anyone have any idea on what this distinct tapping noise could be? had the rocker arms, lifters, injectors and all cam followers replaced and is still present. Noise is at idle and speeds up with acceleration and can hear it inside doesn't affect performance. Been advised by three separate mechanics its not bottom end so at my wits end really, any thoughts appreciated. Thanks a7bcf128-5947-4002-afba-29c811dd5d88 (1).mp4

Does anyone know what this high pitched noise is?

IMG_2335.MOV Hi there, My A1 1.6 TDI Sport 2017 makes this high pitched noise which sounds like it’s coming from the right rear side. It more tends to happen when the weather is cold. It starts when the car has been going for a couple miles and stops as soon as you turn the engine off. I have attached a video of the noise. Does anyone know what this could be? Thanks IMG_2335.MOV
