Please could someone confirm the engine code (3 digits stamped onto the block) for a 2.0 tdi A4 on a 10 plate with 143ps?
I have a colleague who has just bought one of these but the log book says 124ps instead of 143 and he needs to know if he has been missold.
Block 30 is pre and post-cat o2 value and status
Block 31 is Idle and Run Lambda adaptation. This for Air Trim - > 1.0 = Lean < 1.0 = Rich
Block 32 is pre-cat Voltage idle and load
Have you got a genuine cable? If its not, you can't register it and you will be limited to which blocks you can use.
30 - 32 are to do with fuel trim. I don't know why you would have trouble connecting if its genuine
The erratic idle and water temp sounds like a coolant temp sensor. These are really cheap to change. You want a green topped on as the black ones are notorious for failing.
This might help:
With regard to the missfire, its strange that they are...
I would reccomend using Ross-Tech's site and getting it from the states. I did, they Fed-Ex it and mine was in my sweaty palm in 1 1/2 days! I did get charged for import duty but as the $ is so weak against the £, it was a really good deal for me. Not sure what its like against the Euro though...
It still has its limitations as you haven't bought the license. Although I am surprised it won't let you at least connect.
The first problem is definately the cable though. You get what you pay for I am afraid.
Where abouts are you? I could plug in for you if you are close.
I think this is common. I have heard about this before.
They are linked, you can set the controller to make the windows to come down when you hold the unlock button in the fob.
It sounds like the switch is giving the window motor that signal intermitantly in error and the code says to me...
If you go into Central Locks - Coding and hover the mouse over the current code (Don't click it) Does it come up with the options then?
You should be able to add a number to the code to enable the flash.... I think..
I have had this problem too. It occured when I went for new tyres. We had to cut the valves in the end as the aluminium cap corrodes istelf to the valve.
I would try heat too but obviously be careful of the valves itself.... You might have to think about new valves if you can't get them off.
