The Bosch filter box was sealed, and had a replacement o-ring for the filter housing cap. I went back to ECP and they confirmed the other Bosch filters they checked at random were the same, however the MANN version does, so I've fitted that instead. I've emailed Bosch and will report back if it yields a response.

Changed the oil and filter today at 9000k miles since the last mileage interval service and noticed the filter used by the VAG specialist has a soft seal, whereas the Bosch one I bought doesn't. Any thoughts on this guys?

I know from experience there's enough adjustment in the seat to accommodate your height, and getting in will be ok for reasons already mentioned. The only tricky aspect could be getting out because of the low seat and ride height.

The garage is correct. Some good advice here already. Alternatively you can either replace all of them and hope that cures the noise, or what I'd do is forget about until it starts knocking as it becomes more worn, then it'll be easier to identify for replacing.

@Magnet is right. Don't waste time or effort trying to save money here. Get a decent battery and rest assured it has been done properly. You can get a Varta or Bosch from Tanya batteries delivered for around £135. Then have someone with VCDS tell your car it has a new battery. I haven't changed the battery in my A5 yet, but I posted exactly how to do this in the A4 forum a couple of years ago. It'll be different for the B9 platform, but the code aspects will be the same.

Good luck getting this resolved. Do report back on the outcome. It'll be helpful for anyone else who finds themselves in the same predicament.

Do you know the previous owner? The VCDS hack to disable the stop/start will only work with the AC on. When the AC is off, the stop/start works. I can understand why this may bother you. I'd be inclined to have someone with VCDS to check the module. Seems too much of a coincidence. Like @Magnet I switch of manually because of same reasons. I also never have AC switched off, so the hack wouldn't be an issue, but I don't mind pressing the button. This is where you will find in VCDS

If the part isn't VAG approved or OEM the car may not recognise it, which seems to be the case here because the error still suggests it's the throttle body. Unfortunately you won't know unless your purchase a genuine/approved part.

Have you owned your car from new? I don't have the details to hand but there's a VCDS hack that involes the stop/start and AC. Is the light on the stop/start button when it's deactivated?

@Teddynewson suggestion is definitely a good idea. Please do post how this progresses.

Yes indeed - apologies I completely misread that 🙂

Reading your post, you haven't replaced or at least cleaned the MAF sensor, is that correct? My B8 diesel had rough idle issue at one point, and a quick clean solved it. Behaving when cold makes me think it's worth trying here 🤔

My previous A4 did that passenger side front. I lived with it but since moving it on my friend has solved it by replacing the door lock module.

Thanks for the info. How many litres does your tank hold?

Open question: How many miles/litre of AdBlue is everyone getting, and driving pattern?

I think I've missed why you pulled the engine.

You're welcome. Sounds like everything is OK now then.

This link might yield something useful, especially checking connectors. https://pmmonline.co.uk/technical/resolving-an-audi-a4s-adblue-warning-fault/ I don't know about the heater reference 'A'. I've checked the A5 B9 erWIN manual and the only reference I can find to a heater is in the supply line for the V437 pump. Might be helpful to post the full scan, if you have it.

Audi A5 B9 2.0 190 In the interest of sharing info (and to mitigate an AdBlue system related issue) I have been logging what VCDS tells me on some parameters. My driving pattern is a 70 miles round trip for work (3 days/week) of A roads, and several 15-20 minute trips of again mostly A roads. We typically use my wife's car at weekend, otherwise I'll do another 60 miles round trip (minimum) drive on A roads. My driving style to work is either conservative (avg. 57mph to get 76mpg+) or less patient where the economy drops to 64mpg. The shorter runs are less consistent 😃 I only use Esso or Shell fuel with a dose of either Archoil.

These posts are great, and I'm following with interest but I can't help think they should all be in the same thread 😄

Welcome to the forum. When you first had the message 4 months ago, did you topup the adblue or continue to use the car. If you topped it up, how much did you put in?x

I've pulled the filter from every car I've had to check, regardless of what the service history says. Finding a housing full of debris like that has not been unusual sadly. Great share on the "how to" 😀
