I've discovered since buying my A4 that there are a few safety features that, even if you deactivate them in the MMI, they are reactivated every time you start the engine again. These seem to be mandatory for 2024 models. Lane assist is an easy one to turn off - just press and hold the button on the indicator stock to deactivate. Thanks to information I read on the forum, the speed limit warning "bong" that lets you know you're doing 31 in a 30 that was just a matter of adding to favourites. The one that's troubling me is the pre sense. There's a road I drive every day to work that has a narrow double bend with a wall on the near side. I've driven this road hundreds of times but pre sense thinks that I am about to hit the wall at the side of the road most days. Most of the time I just get the red warning but the other day it decided that my driving wasn't good enough and fired on the brakes. Luckily, it was a dry road and there was nothing behind me at the time. That's the wall on the left hand side just after the chevrons: It doesn't look like you can add this to favourites as pressing and holding doesn't seem to do anything and there is no longer the option to set it to late as I have done on earlier versions. I don't believe that it can be deactivated using VCDS, plus I'm unsure of the insurance implications if I was to have an accident and they discovered that I had permanently deactivate it. Does anyone know if it can be accessed quickly without having to go through all of the menus?

Thanks. I am taking it back today. The car drives fine. I would have expected it to be lumpy or difficult to start.

At least you're aware 🙂

Yea that's correct Steve the lad took the plugs off this lot too put on his new set he got as thay where different so I'll be taking mine off the front seats and just swop them over

Service history is key. Ideally it should be full service history. Check for proof of cambelt and water pump changes as well as s-tronic gearbox oil changes and oil changes for the quattro system if applicable. Check YouTube for buyers guides. Make sure all electronic items work as some of these such as AC components etc can be expensive to change.

For this to be plug and play the numbers AND letters have to match. Otherwise you'll need it to be coded.

What a bargain! Be careful regarding air bag wiring though as connectors can vary. As such, if conne tors are different the easiest option is to change the airbags abs wiring from your current seats to the new ones believe it or not.

Have they got invoices backing up the stamps in the book? Admittedly this may not help much though as it'll be in Japanese. Due to the strict MOT rules in Japan, I will suspect it's had everything done. As I believe everything has to work on a car in Japan for it to pass an mot. Make sure the seller is changing the language to English on all car systems. As this can be an issue otherwise. I see your in Ely, if that's London I'd highly recommend you get the supplying dealer get you a certificate of conformity from VAG as this will help prove the cars emissions regarding ULEZ.

I’ve got a 2008 Audi A4 convertible, the COMFORT CONTROL MODULE ECU was broken , I’ve found a new one but just waiting on delivery same numbers etc , my question is … is this a plug and play or do I have to reprogram it to my car 1st

Timing not quite set or out by a tooth.

Glad it's all fixed 🙂 nothing good comes cheap as they say.

Hi Verojie3 and Jag1029. This problem has recently happened to my Audi b9 2018. Did you manage to find a fix? Took mine to the Cardiff Audi dealer and £500 later they could not diagnose the cause. They wanted £1500 to replace the front console with no guarantees that was the issue. Won’t be using them again in a hurry.

im glad you got sorted,best of luck with it for the future.greg

Hi my 2017 Q3 as screen backlights have gone and it’s now black, I read that the wiring can snap due to the constant twisting of the screen. As anyone got any idea which wire from the back of the multimedia unit controls the power so I can check it with my multimeter. thanks

Hi sorry Cliff I stand corrected.

Hi the one with only one connection is for the low pressure EGR, the sensor with two pipes is the DPF sensor they are both the same part number but the EGR sensor on the low pressure side uses barometric pressure from the open side to make its calculations, replacing both is not a bad shout but they will both need adapting, I would still be interested in your soot/ash loadings. Steve.

2 amps when switched off? Perhaps you mean 2 milliamps?

Hi the multi plug for the head unit always has a supply normally about 2amps this maintains the memory functions within the unit otherwise when you power it up the settings need to be altered. Steve.

Tony. How large is this drain from the battery? A few dozen miiliamps is normal for the alarm system. If it is significantly larger look for non-standard pieces of electrical equipment such as satnavs, radios, dashcams etc. and ensure they have been connected to an ignition switched power supply. It is too easy to connect such devices to a permanently live supply.

Hello! First of all I'm terribly sorry if this topic has been talked about, I just want the most up to date infos. I'm in need of a reliable daily that doesn't eat my wallet but looks nice. I'm kinda fallen for the 2.0 TDI A4 B9, 190HP one in particular. I see a few for amazing price, (my budget is about 15.000 euros). Now I would like to know should I be scared of the cars that have 170-190k mi? What should I look for when looking at any B9 with this engine? How good is the S Tronic, and should I look for a manual or S tronic? How easy is the DIY maintenance on these? Turbo and Injector life? Quattro or not, doesn't really matter to me. Any extra advice and stuff I should look for or something that costs a lot to replace would be very nice to know, so feel free to post anything that touches this topic, and maybe some topics I missed. 🙂 Greatly appreciate all inputs!

Watching with interest, thanks for posting. im about ti replace front dampers, top mounts and anti roll bar links on my A3. the top mounts are getting a bit creaky. Dampers look to be originals and with the car past 100k miles replacing them can’t do any harm I suppose.

I should also say that I have seen the service books with stamps. I will view the car next week. I just want to do my research before making that journey.

Sorry I should have posted that. 87,000 miles. I have the VIN so I am wondering Audi can look and see. I would like to think if the Audi dealership serviced this vehicle and replaced items at their appropriate service times they would have also done the gearbox oil and service at its service time.

Hello Joe, Welcome and thanks for joining. It’s difficult to answer your question without knowledge of the mileage this 9 year old car has covered - we take it you know that. As I see it:- unless this car has covered a galaxial mileage, then I don’t see an issue. After all, the seller (direct importer?) has promised to carry out your gearbox oil change and offer a guarantee, so…? My ‘concerns’ would be:- have you already had sight of the service history, have you actually viewed the car, is the seller going to give you a receipt for the work they intend to do pre-purchase, and do they have the facility to input that data ( via. the VIN) onto the VAG on-line service history system? Kind regards, Gareth.

Hello David, To my logic, the suffix A denotes an earlier version of your later B, so possibly from a pre 2009. Significance?? If it remanufactured as opposed to just ‘secondhand’, then the remanufacturer will/ should have the experience to answer any questions about specific differences. Have you asked, and have you had a reply? Kind regards, Gareth.
