If confirming ok isn't working then it makes me wonder if there's an issue with the system. You could do a factory reset of the MMI to see if that helps. Alternatively you could get a diagnostic check to see if any fault codes flag up as to why the ok button isn't responding. This is also linked to the my Audi app. Have you looked in the app to see if there's a way round it?

Welcome to the forum you'll find the members on here are a friendly and helpful bunch 🙂 sounds a nice A4 🙂

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.

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".

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

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.

Congratulations on a successful repair.

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

That's such a kind offer. Hopefully someone will have them 🙂

Any comment Brad on the two replies you have received? I know you have seen them.

Have you tried eBay? Quite a few on there: https://ebay.us/m/Mrz7yY https://ebay.us/m/1LLkwS https://ebay.us/m/nKzHhi https://ebay.us/m/7URvWa

If you've authorised a third party app to access your car (via the Audi APIs) in order to set timers then that's likely to be the cause of the problem. This link should help. https://www.e-tronforum.com/threads/charge-timer-randomly-enables-itself.6994/

This could be a starter motor issue or crank sensor issue. Or according to this thread the sensors that have decide on fuel delivery can be mapped out: https://www.google.com/amp/s/www.audi-sport.net/xf/threads/197826/%3famp=1

If this is the engine you have the red box is the electronic EGR control valve, the green box is the vacuum operated EGR cooling flap solenoid.

If you get some I'd be interested to find out how they look if you could let us know here please. I've got a couple of worn ones myself, usual suspects, heater fan up and down, seem to be the most used buttons in the world. I just set the temperature on mine, put it on auto and leave it alone. Works well enough for me.

Is there a reason for the question Amanda, or just curiosity?

So what did they do to the brakes, and has it cured the noise?

Good plan. Please keep us posted on how you get on

I am really not getting a clear idea of the situation here. Some sort of software was updated, but it is not known which and why. The battery was tested, but no results have been presented to support the "all good" conclusion. The mechanic's "cpu is good but not perfect" so its conclusions can not be relied on. In the absense of firm information about the diagnoses I really cannot add anything further to this topic, however I wish you luck in solving the problem.

I’ve given you one to start Tristian.

Me too lol. Getting the remap removed on Monday morning so I’m hoping if they dig a little deeper that they won’t be able to tell

Thanks for the heads up. Definitely worth noting got other members.
