Hi yes the other thing that stops it working is the fact it is seized, the only real cure is to replace it with the sealing grommet as described in the thread. Steve.

Welcome Peter, Or - cheaper alternative - nip it around to one of Halfords Stores and get the battery efficiency checked. If they do assess it as being substandard, then it’s highly likely that it would be to your wallet’s advantage to return to the forum for some recommendation for alternative suppliers. Any new battery will need to be coded in. Just let us know if we can help further. Regards, Gareth. p.s. Any good reason why you want the engineeringly averse S/S system working?

On newer Audis like the Q8, Lane Assist is forced on by EU rules, so it won’t stay off after restart. The only workarounds are manual switch-off each drive, or a plug-and-play memory module (e.g. D2C Memory Module) that recalls your last setting.

That's a horrifying degree of corrosion which can not have happened in one year, so any MOT you may have must be considered fake. I suggest you get the car inspected by another tester before spending any money on the car in case there is other corrosion to be rectified.

Apologies for the gripe, but the forum has recently suffered from a spate of what can be termed ‘Post and Run’ new members, who seem to think it’s perfectly acceptable to post a plea for help, and simply not return to view the help given. In a more diluted form, help is offered, but is very rarely acknowledged even via. a simple press of the Like button, leave alone a posted Thank You. The last part of the gripe is that we frequently have to ask for additional information, and this extra detail often never materialises. Please remember, everyone who posts replies do so without payment, but it certainly does cost them in time - in terms of the Moderators and Admin back up - a lot of time. So a special plea to all on here who post needing help:- please be respectful enough to acknowledge any help given, rather than simply accept it as a no-cost, no time of yours, free advice service. It’s wearing thin folks, so if you want to retain this service, please respect and acknowledge its benefits. Thank you all for reading this, and above all, agreeing to adhere to the respect that is needed to be shown. Kind regards, On behalf of the Moderators. Please note:- This request is to all members, not just new ones. p.s. Please avoid using non specific locations such as U.K., England etc. etc.

There's two parts to the function (at least on my MY23 A6). There's lane guidance assist which aims to keep the car centered in the driving lane, and lane departure warning which aims to stop you crossing the lane boundaries. A short press of the button on the indicator stalk turns off the lane guidance assist, and a long press turns off the lane departure warning. When lane guidance is on/off a pair of little arrows at the bottom of the icon in the dash will appear (on) and disappear (off). When the lane departure system is on, you'll see two white lines (or green/red according to status) but when it's off, the two lines disappear. These systems are linked to adaptive cruise control as indicated in the owners manual. I generally leave lane departure warning on, but turn off the lane guidance assist except when on motorways or long dual carriageways...

Morning Brad. I have a 23 plate Q8 55Tfsi. It has cruise control but not the adaptive cruise control that your friend has on his car. I suspect that the issue with the lane departure is to do with that. There must be an overlap of the systems somewhere. I would hazard a guess that you would need to disconnect the adaptive cruise control before you are able to turn off the lane assist. Just a guess but maybe you will have to delve deeper into the info folder that came with the car. On a general point I too turn off the lane assist whenever I drive my car. In fact it's the first thing I do! An absolutely useless piece of kit and I think I have read a survey recently that 83 % of all owners who have lane assist on their cars,do likewise. Frank

Even if it is possible to renew just the motor, you would still have the possible problems of damaged gears and leaky seals. Better to renew the whole unit.

Hi you are better off replacing the entire unit not to difficult, not to expensive, but make sure you buy a new rubber grommet as that deteriorates with age and give it a liberal coating of silicone grease when refitting grommet they tend to last longer, thats probably where your leak is. Steve.
