It did work actually, twice. Perhaps there is a delay before it shows on the forum. I have to add that I will not download anything like this from untrusted sources, though I daresay most people are happy to do so.

That the air flow reduces suggests an electronic problem. Best to get the system diagnosed.

£300 for supply tells me they simply don't want the job. Time to investigate alternative suppliers such as this for example: https://wolfautoparts.com/coolant-tpiece-adapter-n90760601-ps43608.html While that one may not be identical to yours, a little time searching the internet may well find one that is.

Parasitic loss is a bit vague. How many amps are being drained from the battery? The handbrake switch under the brake lever may be what you are hearing. It would be worth looking at its condition.

That's better. Having some explanatory detail gives us a chance to provide some assistance. When you filled with oil did add the recommended measured quantity, or did you simply fill to the line on the dip stick?

Tell us what the second opinion was. The evidence you have presented so far all points to an air bag. The fact that it is fairly new does not mean it can not be defective.

No it isn't.

Electronic oil level sensors have reputation for unreliability, so it's likely you need to fit a new one. In the meantime refer to the physical dip stick if you have one.

A quick internet search found: https://hullmotorcare.co.uk/services/engine-rebuilds/ and http://enginerepaircentre.co.uk/

The electrodes are exactly as they should be. The oil on the thread has run down from the plug body because a sloppy mechanic has spilt oil into the recess during topping up.

A trace of oil may be present in an engine that has just started from cold. However it's not normal in an engine that is in good condition and has been run long enough to warm up. Some black hard soot or coke is usual around the end of the thread; while the contacts usually have a pale grey-brown powdery coating. Presumably you have oily plugs or you would not be asking about them, so tell us how much and where, or post a detailed picture.

If you suspect air bags, spray them with soapy water and watch for bubbles.

Alan. There is a potential to damage tyres or bodywork if you get this wrong. I suggest you get professional advice on the matter before changing anything.

That seems to confirm it is the new camshaft causing the problem, though I don't understand how or why.

How long did you own the car before changing the camshaft, and did the DPF block in that time?

I know nothing about Carista or similar OBD readers, so let's hope someone else can chip in.

Michael. Two points which may or may not have a bearing on your problem: 1/ Did you have the new battery coded to the car? It needs to be for proper functionality. 2/ A3s often had faults develop in their instrument panels. The cluster can be repaired for a few hundred pounds or replaced with a new one from Audi for many times the repair cost.

Fingers crossed.

That's good to read, though disappointing it needed to be done on a four year old car. Perhaps the design was updated since your car was made. I would have marked your above message as the solution if possible, but I believe you have to do that yourself.

I don't know for certain, but what I have read indicated the Alko hitch needs more clearance around it than others, hence some installers recommend a swan neck mounted ball. I suggest you measure the clearances around your ball and ask Alko if it is suitable.

You are worrying unnecessarily. 12 mm is plenty and should last months or even years, depending how harsh you are on the brakes and how rusty the discs become.

Possibly one of the clips that secure it is loose or misaligned. Is there any sign it has been removed since manufacture? Think scratches or cracks around the lip where a lever might have been inserted.

It seems to me that you are determined to buy one of these gadgets whatever anybody here or elsewhere advises, so why not go ahead and fit it. Do please let us know how it works out. Please also stop using this forum as a vehicle for your complaints about other organisations. If you want to discuss the merits of this gadget that is prefectly fine, but blatant generalisations about groups or nations is not.

It sounds like you have one of the notorious oil guzzling engines with badly designed pistons and rings that were made for a few years. Many solutions have been tried over time, but the only realistic option is to have re-designed pistons and rings fitted, an extremely expensive option as I doubt Audi will do the work under warranty after 20 years. If you bought it from a dealer in the last 30 days take it back for a refund.

I find most big companies do all they can to avoid talking to their customers. Phones that aren't answered except by robots, AI help assistants that send one round in circles, email addresses withheld, letters that aren't answered. It all amounts to taking your money then hiding behind impenetrable barriers.
