I bought this A2 about 14 years ago for £3500 if I remember correctly, then sold it to a distant family member about 6 years ago for £700, and have just now bought it back for £200, which may or may not be a bargain.
It's a 1.4 TDI Sport, and it's generally body wise in great condition, so that's a bonus, but it has plenty of other issues. Possibly the worst of which is a bit of a crunchy 3rd gear. If you are very careful a clean change is possible, but it's not ideal of course.
I was told it had lots of issues, and knew that the battery had been going flat overnight, so a gate switch had been very badly fitted to the battery as a solution. The battery is quite new but not as big as it should be. The central locking isn't working either, but I was told it was the battery in the key. Today I charged the battery, and have just hooked up a clamp meter to test the quiescent draw on the battery. I got a reading of 0.05 amps, which seems okay I think?
So I think I will start from scratch forgetting what I have been told, and try to figure out what's going on.. My cheapo OBD reader has thrown up the following:
01463 Alarm Triggered by sensor for anti theft system
01333 Left rear door control module
P125600 Coolant temperature sensor open circuit/short circuit to B+
P155600 Charge press. Ctrl. Value below lower control unit (Turbo)
00778 Steering angle sensor
P057100 Cruise/brake switch (A) Circ. Malfunction (Brake light switch?)
I researched all these issues online last night, so I have a bit of an idea what they are about and where to look next. I think I'll start with putting a new battery in the key, to see if the key is the problem, or if there is maybe something up with the CCCU, or the Left door control module is causing problems or??
