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.

Hello Jon.  I purchased the car 2nd hand and it is nearly 5 years old. The light on the centre console is unlit at all times, but the little A on the dash comes on green when the a/c is off (and the engine cuts out) but comes up with a line through it when the a/c is on, suggesting I have disabled the system when in fact, I have not touched it.

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

Hello ,

My son to the car to Audi West London, and he had fully explained the issue and steps taken to fix it. As usual, the follow set procedure and plugged it in, fair enough at £130 per hour.

Got a message from them saying computer says it's a faulty throttle. Just because it is not the original part even though my son explained that this was a compatible replacement for the original part. The guys just go by the computer blindly without question and said they will start with original throttle body £ 570 not inc. VAT but quoted over £1000 including fit.

They said the part was faulty because it was a non-genuine part but these guys just didnt want to listen!!! My son said that he could bring the original part removed but they turned around and said that could also be faulty!

They then said this was no guarantee that this would fix the problem to which they said they want to help but this is the way to go. My son said that there was no difference in the Audi dealer approach and the independent mechanic, and they had no answer to that when my son said that they are guessing and car could cost £10,000 to spend hours diagnosing and changing different parts until they kill our wallet.

So, a very bad result indeed and no better than the independent Audi specailists!

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.

Hi Dragon,

This car (1.8TFSI engine) doesnt have the MAF, only the MAP sensor which has been replaced.

The mechanic said start with what is the cheapest parts first . The only thing that we haven't changed is the entire PCV assembly. But we did change the PCV rubber gasket which can deteriorate with time.

thank you

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.

I don't have full scan mate, 650 miles warning disappeared yesterday but came back again today. At least it reset back to 650 miles again. Car runs fine with out any issues and still doing dpf regens as normal.

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

This link might yield something useful, especially checking connectors.

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.

The data can be found in VCDS under: 01-Engine > Advanced Measuring Blocks > Look for 'red' values in the pop up menu

So for my vehicle, the AdBlue distance until deficiency drops at half the rate of actual mileage covered

I think I might do as others have suggested and ask the VAG specialist I go to for the next top up in approx. 14000k miles which will mean I shouldn't run it down the low low warning.

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" 😀
