That's a very convincing recommendation.
Is this the correct version?

I'm working through a couple of errors found in a scan.

What happens is the aircon seemingly goes into 'recirculation mode' shortly after starting a journey with no lights indicating the setting has changed i.e. the flaps at the bulkhead intake close, which throttles the air flow through into the cabin vents. A visual check in this error state has confirmed the flaps at the bulkhead intake are closed, each and every time air flow is restricted into the cabin. Something to note; if I press the windscreen button the air blasts through, but still not through the vents.
If I select 'air con off' the flaps at the bulkhead intake will open (if they are closed with 'air con on') allowing air to flow through the vents - this would be ok if I only wanted warm air.
Something else that happened is the fans were blowing according to the speed level setting I had selected at 20degC but I was getting warm so I reduced the temperature, which in turn reduced the fan/air flow speed into the cabin (the speed level indicator on the display did not change). This seemed repeatable when increasing the temp again, but the air flow speed topped out at 20degC, so I reduced the temperature again down to 17degC in 0.5 increments, and the fan consistently reduced and held at each change, then all of a sudden the air flow speed went back up according to the speed level setting on the display. The next time I was able to pull over and observe the flap positions for each temp setting:
I have found that if I stop and start the car, the behaviour sometimes corrects itself.
In an attempt to resolve this, I cleared the error and did the following with VCDS:
[Select]
[08-HVAC]
[Basic Settings]
[Drop down menu: IDE01546-adapt door end stops]
[Go!]The routine completed with no errors but still I have the problem (and an additional error code: 65543 - No Basic Setting B2010 09 [009] which just will not clear).
I think I have two options here:
1. Replace the recirculation motor. According to the erWIN Audi repair sheet I downloaded it's 4M0.820.511.A
2. Pull the flaps open essentially mechanically fixing the position, and ignore the error code (I don't use recirculation anyway).
However, if anyone has any suggestions I would be happy to consider them (also posted on Ross-Tech forum).

I appreciate the explanation, so thank you for taking the time to reply.
My engineering mind is running wild with this, though at some point I need to accept the system for what it is, and enjoy the car.
From what I can understand, the soot values I'm seeing are OK and will be easy to manage with decent fuel and the millers/Hydra/Archoil with my current driving schedule?
I'll definitely be using the cataclean. Is there a recommended frequency for using it?
-
Not cataclean yet but I did my usual 34mile (x2) trip to work today and hooked up the VCDS to look at this again.
The error code has not returned and values as follows:

---------------------------------------------------------------------------------It looks stable currently.
I wonder if there is any possibility that the initial error was caused by some build up being dislodged(?) since the car has been moving again, and I've been using Millers Diesel Power Ecomax (used with my old A4 B8 with good results) which has now been burnt off - too early to tell perhaps.
I've been posting this on the Ross Tech Forum should anyone not be familiar with that resource

Quick update:
On Friday I did a 40 mile drive, then a few days of short trips, and a 40 mile drive on Monday. Today I drove to and from work (34 mile) and checked the soot values which were:
IDE00434 Particle filter: soot mass calculated 22.48 g
IDE00435 Particle filter: soot mass measured 6.52 gThe car stood idle for ~2 hours then I took my son to football training which is a 10 minute drive of A roads. When I got back and parked the car, the fan was running so I checked and it was doing a regen.
I measured the values just before the fan stopped at:
IDE00432 Particle filter: time since last regeneration 7.547 H
IDE00434 Particle filter: soot mass calculated 11.19 g
IDE00435 Particle filter: soot mass measured -0.23 g
IDE00436 Particle filter: kilometers since last regeneration 367.5 kmLooking at them again, the values had reset for time and kilometres since last regen
Research suggests the regen should happen every 483km/300miles, so this was a little early but the fault code has disappeared.
I'm still planning to use the cataclean when it arrives, and will likely monitor this over the next few weeks to better understand what is happening.
-
Can you post a photo?
-
I'd have a look on eBay for the part, or A5s being broken for spares
-
Thanks for the links and info.
I'm planning to try the cataclean next week when it arrives, so I'll report back.
It could be that now the car is moving again, and I've been using Millers Diesel Power Ecomax with every fill (Esso), a bit of crap has been shifted and that's what has thrown the error so just needs a few regens/help to clear.
-
This is really interesting; thanks for the explanation. What is the measurable I need to look at for the particle trap?
Most of my driving to work (3-4 days a week) is 30 miles each way of A roads, and I average 60 mph sticking to the speed limits. Is there a better alternative to the Millers for that?
The cataclean should be here next week, at which point I'll be able put it straight in the tank and run it to work.

For anyone looking to do some coding with VCDS, here are a couple of helpful resources:
https://www.a5oc.com/threads/complete-vcds-vagcom-mod-list.28600/
The changes I've made so far:
Gauge Test/Needle Sweep
[17 Instruments] > Coding-07 > Long Coding Helper > Byte 1 > Enable Bit 0
--------------------------------
DRL option in MIB:
[09 Central Electrics] > Coding-07 > Long Coding Helper > Byte 2 > Enable Bit 1

Configure these channels as desired:
Lock sounds: ENG146372-ENG146515-horn_settings-number_of_acoustic_acknowlagement_signals_zv_close (default 1 beep)
Unlock sounds: ENG146372-ENG146514-horn_settings-number_of_acoustic_acknowlagement_signals_zv_open (default 2 beeps)My car was already set with the corresponding number of hazard blinks to match the sound, so I've left as default.
--------------------------------Does anyone know how to do the following:
1. disable the 'passenger air bag on' warning/chime that is displayed every time the car is started
2. disable the 'engine running' warning/chime every time the drivers door is openedI've got plans to do a few more, so I'll post the outcome.

Has anyone removed and cleaned the EGR valve on a DETA engine? I attempted it yesterday but it looks like there's so much to remove, I abandoned the task.
I'm assuming it has never been done on my A5, and at 60k it's likely to be in need of a clean soon, if the build up is similar to my old A4 B8 diesel that I cleaned every 30-40k.
Given the effort, I'm wondering if a more frequent "remove a pipe and spray clean" would at least manage the build up, though knowing what it takes to actually clean the valve, I have low expectations.
I'm also wondering where the crap goes downstream from the insitu cleaning method e.g. stuck in the CAT?
If anyone has some experience to share, I'd be very grateful to learn from it.

Hi give it dose of Cataclean I used it on my daughters Q3 which when purchased had only done 12 miles a day for most of its previous life and suffered with this sort of problem, follow the instructions to the letter and the most noticeable thing on her car was the ball of rubbish that shot out of the exhaust during the first cycle drive the car now runs like a steam train and does more miles now so a year later the problem has not reappeared. BTW no such thing as a passive regeneration on these cars that only occurs on cars with early cordierite cored DPFs, Ford, Fiat.
STEVE.
Steve.
Hi Steve,
Thank you for the suggestion. I've ordered the cataclean and will report back.
My car was running fine, responsive, mpgs were high 70s and no light. I only picked this up from a scan, so it'll be interesting to see if it yields some improvement.
Do you know what 'time since last regeneration 4.287 H" means from the first set of measuring block data?
Edit: as a side note, I've only had the car for a few months (driven 3k miles), it has full Audi history and I did an oil change after a week, just because. I only use ESSO diesel and put a shot of Millers Oils Diesel Power Ecomax in with every fill up) as I did with my A4 B8 🙂

A random scan brought up the following error code and measure values from the DPF (no amber DPF warning light on the dash):

---------------------------------------------------------------------------------Some internet research led me to going for a drive at 2-2500RPM (basically 60mph in 4th gear) for >20 minutes to burn some build up off the DPF. That didn't work, so I followed the support on the Ross-tech website and did a regeneration at idle for UDS.

When the process had completed after about 12 minutes, I did another scan and measured the values again.

I didn't log the oil ash mass initially, but it went up by ~0.005g
The first set of data suggests the car has recently done a passive regen, which was likely during my drive to/from work.
Any help/nudge in the direction to understanding the output from the regen/if something else needs investigating would be much appreciated.
Also, the EGR values are a mystery to me. What do the % mean?

Hi all,
I have an old HEX-USB+CAN cable (unlimited) and a recently purchased HEX-V2 cable (limited for now)
Is there any scope for offering this as a fixed price donation type service for members in the Peterborough area?
I was considering travelling to the owners home address/meet a mutually agreeable location for either:
Scan and clear all DTCs including an emailed copy of the log for £30
The above plus one adaption (done by car owner) for £35 + £2.50 for further adaptions
Any thoughts would be appreciated or if you're interested please get in touch
-
Nice work
-
No worries. It's not something we have to think of as they're usually changed with tyres; for whatever reason mine weren't and they had perished/split.
The first DIY setup to change them was interesting. In the end I used a block of wood and the weight of the car to separate the tyre from the rim 😃
-
Just to close this topic; I bought valve type TR413 and they're a perfect fit.
-
Or the value type needed to fit these wheels? 🙂
-
These guys are good too
-
Silicone grease is a better choice if you lubricate them again. It sounds like you need to replace the guide rubbers (and probably the pins).
Try this company:
They have a shop on eBay too.
I bought a pair front caliper repair kits (piston, giude rubbers, pins, seals etc.) from these guys to rebuild my B8. Quality parts and when doing the job I split a seal, and they sent me out another for next day delivery.
-
Does anybody know the valve stem hole diameter for the 18" Ronal alloys?
-
Ok that would be great, thank you.

I'd just need to manipulate the setup so the flaps are always open. Should be easy enough. I'm fitting a honeycomb grill tomorrow afternoon, so I'll probably have a look after that if there's enough daylight left 😄
