As a mere stripling of 73 I have only been jet washing my cars for 25 years and they have never suffered any damage, though I must add two caveats: 1/ I use only water, never any additives. 2/ Car cleaning is done religiously twice per year, whether it needs it or not!

In that case I can not help.

Loads of parts tells us nothing. Have you replaced the hub as Magnet suggestd?

A "passive" issue? That's just the sort of explanation that explains nothing. My guess is that the dealer has no idea what was wrong. However it is good that you took it back as the dealer has presumably recorded the event, so if it happens again soon you have good reason to reject the car.

Good news, and kudos to the garage for replacing the pump thereby eating a large chunk of its profit.

Jonathon. Is the handbrake mechanical or electrical?

I am a little confused about whether you are discussing the oil pressure sensor or the oil level sensor, either of which could be defective. Is there an old-fashioned dipstick to first establish if the oil level is genuinely low?

Nevertheless from the viewing angle of the video it looks as the clamp is cutting into the hose. Perhaps that's a false impression because I can not reconcile the long hose shown in the still pictures with what appears to be the short elbow in the video. Maybe that's just the perspective of the view. If it is a genuine Audi part it will have been made of a rubber that will withstand the temperature of its environment, however you mentioned it was vac pipe that you fitted which will have a different composition. Two other thoughts occur to me: 1/ I wonder if the degradation is caused by rubbing as the hose vibrates. Are any securing clips missing? 2/ Did you inspect and clean the stub of pipe that the hose fits over? Aluminium can corrode badly causing a poor seal between rubber and metal.

What sort of hose clamp have you used? It looks like a mis-shapen piece of wire that is cutting into the rubber hose.

Do you know there is more than one fusebox on A3s? My 2007 model had one under the bonnet and another under the dash.

Yes. Don't waste your money on any of them.

Michael. Have you looked at the Q2 forum? It might give you some opinions there.

It will depend how thick the wall thickness of the new hose is. Vacuum hoses have either more rigid reinforcement than pressure hoses, or thicker walls, because it is easier for a hose to resist internal pressure than external pressure.

Don't trouble yourself about the video, your words are good enough. After that I am at a loss so let's hope somebody will have a suggestion.

Sorry to teach granny to suck eggs, but are you certain that all the indicators are working? I read of a similar problem recently where one of the mirror or wing indicator lamps had failed yet the front and rear main indicators were still working.

Daniel. I can not answer your question, but surely a two year old car is still under guarantee from the dealer who sold it to you.

I am being "testy" as you call it because the forum is being plagued by people like yourself who pose questions and never bother to look at the replies that others have spent time and effort on. If your problem was important enough to spend time composing your questions, surely it is worth a little more time to read and aknowledge their replies? Is that really too much to expect? If nothing else, the matter is one of good manners.

You should not need to be brutal with the bonnet or even slam it hard. If it can not be secured by lowering gently then pressing above the latch, it needs adjustment to the latch.

I would not spend money on a new motor without testing the fuse first. I am surprised the fuse is not shown in the handbook. Look at the underside of the fusebox cover. You may find some information there.

It may be a poor connection at the bulb or a plug. It would be worth having a look before spending money on new lights.

No, your key will not fit another lock barrel. Furthermore if you change one lock barrel you will need to change all the others (such as doors and boot) if you want to operate them all with a single key. On the other hand it may be possible to fit your old barrel into a new switch. It is not something I have done so I am unsure. Perhaps others here can advise.

You didn't even look? It seems that two people wasted their time answering your questions.

It could be either. Take the tension off the belt and rattle the pulleys to discover which is loose. The AC fault may not be related. By the way, you have posted two previous topics about odd noises from your car without letting us know the outcome. How about responding to the replies you received, or at least aknowledging that you have read them.

Kevin. I imagine the market for such an old car is very small, unless it has some significant history such as a famous owner or the winning of a rally for examples. That two traders are uninterested seems to confirm its lack of appeal, so Ebay is the only thing I can suggest that will reach a wide market, but be prepared for a nasty shock at how little money you will get for it there.

Gordon. Just to add, even if the wheels were balanced when the tyres were fitted, pot holes and kerb climbing can dislodge the weights. If balancing does not solve the problem we need to investigate elsewhere. Although I had a 2 litre diesel A3 2007 until three years ago I don't really remember what the fuel consumption was. I recall it was typical for its type and not unduly thirsty, but beyond that I do not know. In any case a car's consumption always depends on how it is driven and on what roads.
