Hi, I am unable to remove the message on my screen so any suggestions would be most appreciated. I have tried every option on the touch screen but nothing so far.

Thanks for your interesting comments. I have bought very little on eBay and never from a foreign supplier, so I am very wary of doing so. However, I'll investigate further and probably contact the supplier to see if I get a professional response. I'll also have to check on Monday how long the garage is willing to hold the car.

So my EML light came on the other day, decided to attach my diag to is and its showing two error codes.. P023B00 - Charge Air Cooler Coolant Pump Control Circuit Low P023A00 - Charge Air Cooler Coolant Pump Control Circuit/Open I located the pump and actuated the pump via my reader and it seems to be working and you can hear it when you unlock the car and open the bonnet. You can feel it working too. However I did notice that the A/C pipe that runs under the pump looked like it was wet, indeed when I got under the car and checked it looked like there was a very small amount of coolant coming from the pump around the connector area it was enough to moisten the tip of your finger. Looking at the hose attachments they seem dry, but it seems the leak is coming from the pump body itself or around where the connector attaches to the body. When clearing the codes the EML light went off but the P023B00 remained. Then when driving the car, switching it off and then starting the car again the EML light comes on and the P023A00 code is back. I'm guessing that even though the pump is working its pulling too much current/shorting as its leaking coolant through the body and throwing these codes. has anyone else come across this before? I mean to me its pretty conclusive as to what the issue is but its always good to ask other opinions.. Also the pump doesnt seem to have a part number on it, just the Audi logo, a QR code and made in Italy (Typical) I did look it up but there are a number of different pump part numbers for this is there a specific one I need to use for this? So far I have found 4H0965569A which seems to be the one.

HI all, I thought id' introduce myself first, I live in Southampton and have recently got a 2016 Audi A4 Avant as the family wagon as we have two children and a whole host of things to cart about for family holidays etc. I've always wanted an Audi as a family car, We used (well still do) have a Nissan pathfinder which was great for family trips and could tow my race car, but as it was getting a bit old and I was going to hit 40 I was thinking of getting something like a 2017 SQ7 but then life happened and then I ended up having to purchase a new kitchen 🙄 we had a small electrical fire which resulted in having to take the kitchen apart and when we did it was apparent that the whole kitchen needed a full rewire and the cabinets were just falling apart when taking them down, so that took my budget for something family, fun and practical to tow with. So in the end I've kept the Pathfinder for towing and decided on getting an A4 Avant. Apart from a couple of niggles, I am very happy with the A4. its the Sport Ultra, so doesn't really have many options, I mean my wife will mostly be driving it anyway and she doesn't like all the technology these days anyway so I guess that's good. I was looking through the history and see that its had a stage 1 re-map, which I wondered why it felt a bit quicker than others I test drove. I do have some niggles with the car I wanted to ask the forum about, but I'll keep that to the technical section. Many thanks, I hope to stick around for my Audi Ownership.. I'll try and help where I can too.

A bit more info for you mate. Efficiency mode is a mode designed to optimize fuel or electricity consumption and maximize mileage. In this mode, throttle response is subdued to reduce power consumption, and the AC system is put in ECO mode. Throttle, transmission, differentials, adaptive cruise control, and even climate control parameters can be managed to reduce mechanical resistance and improve efficiency. You can use Drive Select to pick Efficiency and get the most efficient group of settings, or use Drive Select to select Efficiency MODE, turn the car off and on, and you will get "Not Quite As Efficient Efficiency Mode".

Thank you very much,I was just bit baffled with it.

It's the DIS Efficiency Programme light, nothing to worry about. It just relates to things the effect your MPG, stuff like using your AC etc.

Yes,I can't find any answers.

The green symbol, sorry, question mark not working on keyboard.

Hi there Could someone tell what this light means that has come on please?

Good idea on the rolling road, hadn't thought of that.

I'm definitely with Steve on this, get it scanned for faults first, could be something simple and if nothing shows up at least you know. After that if it still feels wrong get it dyno tested on a rolling road and found out if the torque and BHP figures are badly out or if they're sort of in the ballpark for what Audi are claiming.

Just from experience I needed a rear axle for my A6 last year, all the ones from breakers in this country were nearly as bad as mine, but I found a brand new remanufactured one from Poland on Ebay. The price was fair, quality was excellent, and apart from HMRC wanting their pound of flesh at this end delivery was smooth and hassle free. Check their reviews mate and use PayPal for your own protection, definitely preferable to scrapping the car.

I've just noticed, one the clubs current advertiser's does custom hoses! Go to the bottom of the website to see the ad/link. You should get a discount

You're welcome, that I'm not so sure. You might find the issue won't be getting it down but getting it back up and sealing properly

To be honest I would avoid AliExpress for an important (and probably still quite expensive) part like that. I play guitar and some of the fake branded instruments I've seen people pay a few hundred quid for from that site have been truly shocking quality and not fit for purpose, so I can only assume you would be taking the same sort of risk with automotive parts. Now, if a guitar turns out to be an unplayable piece of junk that falls apart after a few months you end up looking stupid and out of pocket, if it's an important piece of equipment on your car the result could be far more serious, costly, and could land you in court even. You are FAR better off using EBay if you don't want to pay dealership prices in my opinion.

You're welcome, please keep us posted on how you get on

Congratulations on a successful repair.

It is possible, but the air quality sensor was short to ground and required replacement. I'll post on this topic at a later date if it manifests again along with anything else that ends up being worked/replaced. The garage I spoke to said that a car they had in had all manner of issues due to an air quality sensor failure. Affected rear camera and all sorts. Personally I don't like faults you can't turn on/off as there is still the uncertainty. Unfortunately I'm not in that position so have to live it. I've completed over 500 miles since so feels promising.

Is it possible something you did has secured a poor electrical connection caused by corrosion/weak spring/unfastened clip etc?

Thanks for this, but would this still be possible if one of the rear windows was up fully as does not operate cheers

So it seems that replacing the air quality sensor has resolved the issue. Don't ask me why but it is now sorted.

Ooh ideal, thanks for your help

You're welcome. Totally agree I'd loath to scrap it too!

Hi! I just picked up a 2022 e-tron 55 yesterday. I’m coming from a VW Passat and I live in cold Sweden. As such I frequently start the parking heater beforehand so it’s nice and cosy. In order to do the same thing with the e-tron, do I need the app myAudi? I bought the car used from an Audi dealer but I didn’t get the Vehicle code so I can’t register the car in the app. After some googling it seems like they are charging for a new vehicle code? Does that include the Audi app cost or do you need to pay for that as well? And I’m guessing this app is needed if I want to be able to check how much battery is left etc? Thanks in advance
