Why would one push rod be longer than the other? Is the floor pan a different shape on either side?

Kevin. I have merged your two identical topics into one and moved them from the Introductory section to the A3 section. Please do not create duplicate topics.

Sorry to read of your plight Kevin. It sounds like Audi and the gearbox builder are each clutching at straws in their diagnostic guesses, then trying to pass the buck onto the other when the guesses prove to be wrong, all the while happily taking lots of money off you. All I can suggest is that you find another gearbox specialist to diagnose the fault, one who is prepared to back up his diagnosis with a guaranteed fix if you should award him the work. I am not in your neck of the woods so I don't know of anybody suitable. Whether you can recover some money from the clowns you have consulted so far will depend on the success of the final repair. Professional legal advice may be needed on this matter.

I have no idea where it is. Fortunately my Audi was from before the advent of Adblue so I never had to concern myself with it, and my little knowledge of the matter comes from these forums. Essentially the system is known to become clogged with crystals. You will have to search for the information yourself on how to deal with it, or wait for somebody more knowledgeable such as Stevey Y for detailed information.

Search the rest of these forums and you will find that Adblu systems are becoming notorious for the problems they create and the cost of fixing them. You will also find possible solutions.

He did not unlock it he broke it, so it's only right that he pays for a new one.

I have locked this topic as it is a duplicate of one in another section.

Fair enough Matt. You probably know more about the coding aspect than I ever will, however as a chemist I do know enough to realise that one can not treat all batteries the same when it comes to charging. For example lead-acid batteries will tolerate a lot of charging abuse, calcium chloride batteries less so, while lithium batteries (particularly LMC) must be treated with kid gloves when it comes to charging. I assume that aspect is at least part of the reason for battery coding.

While coding a battery to the car may not be a good description, it is the term used by those I have met in the trade. I have no idea how it is done but there is no doubt that the car's software needs to be informed of the batteries capacity, type, and chemistry for the charging circuitry to operate correctly. Long gone are the days of dynamos charging lead-acid batteries to any value from 12 volts to 15 volts with no impact on the battery's performance.

Approved by whom? What sort of guarantee did the approver offer?

Any progess on this John?

Fuses don't blow of their own volition. There must be an electrical fault which you need to get diagnosed. Nobody here can make that diagnosis without knowing what circuit is protected by the fuse, what symptoms the car shows, and what error messages are present. If the car was cheap because of this fault there is a fair chance repair is going to be expensive, else the seller would have done it himself and got a better price.

What has getting old got to do with it? I was 29 when I got my first automatic and I would never return to a manual box. I don't understand why anyone would want to wiggle a metal pole sticking up from the car floor just to make it move from A to B, as if he was stirring a pan of porrige.

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.

Assuming Motorpoint counts as a dealer, take it back for the company to sort out at no cost to you.

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.
