rear spoiler warning light

Hi all,

I recently took my Mk II TT into an Audi/VW specialist because the rear spoiler has suddenly started to throw a warning light on the dash when it deploys. They took a look and told me that the sensors/micro-controllers on it were faulty and that unfortunately to repair it would mean replacing the entire spoiler as it was only sold as a complete unit at a cost of around £750! This sounds crazy but I'd just like to check with anyone to see if this is a known fault and if the figure they quoted sounds about right. I've used them before and always felt that they were reliable and honest so I just wanted to double check this with the community.

Thanks a lot,
Neil

Thanks all,

I've spotted a few spoilers on eBay that look like they might fit the bill. Not being mechanically minded I'm fairly sure the one I've seen is the part I'm looking for but could use some advice. It is labelled as part #8J0827948D - does this sound right for a TT Mk II TFSI quattro petrol ?

Of course I'm assuming that it's fully functional but I guess that's the risk you take with a second hand part..

Cheers

The mk2 is an 8j part code. You could either buy a spoiler in your colour or I guess you could buy any colour spoiler and swap the motor unit over ?

The reason the garage were so dear is likely they were buying a new part from Audi and having it painted or I suppose perhaps they are just really dear and planned on using a used part.

Anyway this video will give you an idea about rear spoiler removal

Does anyone know if the rear spoiler fails a lot? I'm thinking of sourcing a second hand one from eBay, rather than the £599 (excluding labour) that Audi have quoted me, but I don't want to fork out for a part that is likely to fail again at some point in the future.

I'd have thought if it's a design flaw it should be a recall job...

From comments on this forum, complete failure is rare; in fact I don't think I've seen any other report of that.

However there have been any number of people saying that the spoiler had got stuck and that was often due to lack of lubrication of the mechanism that raises and lowers the spoiler blade.

I would hope that your garage has tried that and ruled it out - I hope.

You say it throws a warning light when it deploys. From that I understand that it does move. Maybe it simply isn't moving far enough? Has that been checked?

Hi Brittan,

The spoiler deploys OK but as soon as it does the warning light displays on the dash and it beeps at me. I can't remember if it automatically retracts, I need to test that. It manually retracts it OK.

I'm sure the garage has checked for a seized/non-lubricated mechanism as they mentioned it to me the last time saw them but I might try that myself. Is this silicone lubricant you're referring to and I guess it's the arms/joints that need lubing up?

Regards,
Neil

Being as wet as your Island gets, it probably makes sense to stay on top things like this. Also door, trunk, hood hinges, etc. Swissyland is pretty dry, relatively speaking, and my Roadster had the benefit of a garage to keep it out of the elements. But I'm going to make a point of including lubrication of all the hinges as part of my personal annual preventative maintenance program every spring. Along with swapping out key fob batteries.

Was just assuming the mechanics would have tried to lubricate the spoiler. As above really, not sure what fault code a spoiler throws as don't recall proper spoiler burn out mentioned before.

Another option if you have to replace the spoiler is a fixed wing either Audi sport or rs spoiler with the Audi sport being more reasonably priced. Did you ever use the spoiler? Another option if it's down is just to disable it via vcds, simple check box but really just glossing over the problem

Well, my thinking is that if it's throwing up a code on the dash then something will be stored as an error. So will be worth looking at. Could be a sensor, could be a fault with the CAN module... could be a number of things.

Is it worth unscrewing the spoiler and spraying the motor and servos with some contact spray? often when sensors fail it's just due to muck getting in them and the innards of the spoiler are open to the elements when the spoiler is up. For the sake of £3.99 for some contact spray and 20 mins it's worth a go.

The garage I use are pretty reliable and I believe them when they say that it requires a replacement spoiler, however I have ordered myself a tin of teflon lubricant spray so I'll give it a good clean out and give it a go. You never know, it might fix it.

Thanks Joshers, but my car is white. Otherwise I'd be interested :(

I'm not keen on fixed, static spoilers. To be honest I think they look a bit naff (no doubt I'll get flamed for that!).

Afternoon all,

I've cleaned the spoiler up and applied some teflon spray to it. Interestingly it manually deploys and retracts OK but the warning light still flashes up and beeps. I decided to take a quick video when manually deploying. If you watch closely you'll see both arms extend to full extension when the spoiler is fully out before then bending back ever so slightly. I think it's at this point that the warning light trips.
