David. This topic is a duplicate so I am locking this one. Posing the same question several times will not gain you any advantage.

In addition to Steve's comments, it may also be the Mechatronic unit within the gearbox, which was a source of problems in earlier A3s. I suggest you it diagnosed at a Audi dealer or a VAG specialist.

New topic please. I am locking this one.

A shame you did not mention that earlier. Whenever you swap wheels or change the pressures the TPMS needs to be recalibrated.

Well done.

Motorway journeys are faster than other roads so the tyres get hotter and their pressures higher. Is it possuble that the TPMS can warn of high pressure as well as low?

Rory. You have not yet told us what this rear light problem is.

Michael. Can you reverse your tester so that it applies negative pressure instead of positive? If that pulls bubbles of air from the cooling system into the reservoir it shows it to be air locked.

True, but I would personally prefer a paper manual that would not be damaged by falling on the ground or having a greasy spanner dropped on it. Maybe that says more about my age than I care to admit.

I am not familiar with this model, but theoretically it is possible that if the AC drain is blocked then condensate may fill the heat exchanger to the point that it overflows into the air duct and enter the cabin.

I am not saying anything of the sort; I am saying I don't believe an oil separator will solve the problem of crankcase pressure. I suggest you get a diagnosis and second opinion from a different garage before committing any money.

I did wonder briefly if it could be associated with the EGR removal, but said nothing as I could not imagine how the bolt would get into the engine. Are you going to claim against the company that removed the EGR?

Yes the cost was expensive, but unless you can do the job yourself you don't have any option but to grin and bear it. My worry is still the origin of the nut. If it fell off some other component then that component is liable to fail at some point. I assume the garage would have identified it if possible so I suppose it must remain a mystery. Regarding the password change, there can be a delay in registering that sort of change in my experience. I don't know why that should be but the forum administrator will probably be able to explain it.

Yes it is. Panel lights come on for a few seconds to show they are working. It is called a lamp test and clearly yours has failed the test.

That sounds like a good plan. I hope you have a fat wallet as it is never advisable to ignore warnings related to 4WD transmissions.

The only comment I will make on that part is that it is unsuitable for your car according to the supplier you quoted. Q3 2013 is not listed. I am not in any case convinced an oil separator is going to solve the problem of crankcase pressure if you have changed the PCV, or EGR valve as it is called here. Furthermore I don't see why you would buy any part from America given the scale of postage costs across the Atlantic.

This could be a long night if all your replies are to be monosyllabic. How about giving us some details so we can try to resolve the problem.

It always has been Gethin. There was a lot of truth in the TV series "Minder" four decades ago, and little has changed since those days.

Robert. Why have you rejoined the forum under the guise of Elvis08 when were already a member as robert eckersall? Do you have a problem logging in?

Geoff. I have moved your topic to a more appropriate section than Introductions.

That's normal for all extended warranies and applies to almost any part that might be claimed for. I really don't understand why these worthless deceitful so-called warranties have not been made illegal. Their only purpose is to increase the salesman's salary without any risk of paying a penny to the customer. Learn the lesson Leo, and never buy one again.

£2500 for a head overhaul does not sound too bad on the face of it by modern standards, particularly as the timing belt and water pump were included in the job, but there's something incomplete about the explanation. Firstly, where did this errant bolt or nut come from, and how did it enter the engine. Secondly, if a bolt or nut had found its way into the engine and thereby damaged a valve, the repair would have needed at least one new valve yet there is no mention of new valves on the invoice unless that is what is meant by "cylinder head set".

Fair enough, but why not say so from the start. The forum name you have chosen for yourself is bound to raise suspicion.

Is that wise? It could be as wrecked as your existing joint.

Sharks!
