    Temp icon coming on first turn of the key at the start of the day

    On another note, the coolant level sensor does slowly become covered in some sort of residue. One result, it needs to be more completely immersed to stop showing the error, so it quickly goes away as you start driving. Another result, it begins showing an error when it is cold outside, and again...

    Replacing the 1.4l AUA motor

    And now I'm even more confused, because the CGGB ECU has a completely different connector, as far as I can tell.

    Replacing the 1.4l AUA motor

    OK. I gotta ask. how was the CGGB swap done? Did it simply require the matching ECU, or were other adaptations performed? CGGB supposedly does not have EGR, so the same ECU should not work... so did the new ECU work with the original dashboard and ABS?

    How to get the plastic U clip back in place for the coolant temperature sensor ?

    Are you certain you have G12 in the car? It was being discontinued right about the time the A2 was being manufactured. If you know what you have (either G12 or G12+), buy what you have as they cannot be mixed. If you do not know what you have, buy G12++/G13 as they are more modern coolants and...

    1.2 TDI motor mount (8Z0199212k)

    It probably is unavailable aftermarket because they were only making them up until like 2008 and then selling stock. When Lemforder ran out, they stopped selling it. The same happened with the 1.4 petrol mounts. VW also is going to run out of stock someday, as they have for other A2 parts. Now...

    1.6 FSI In-tank Fuel Pump - Same as 1.4?

    As I understand it, 8Z0919051A is for all types of petrol engines up to 29.04.2002, 8Z0919051C is for all petrol engines after that date. And the fuel sender type switches over on the same date. In any case, as has already been stated, aftermarket pumps (at least as long as they are only the...

    Oil leak

    If you have the "throttle" valve (I do not know which versions do), one reason it is there is specifically to prevent runaway.

    Window fault

    I have a feeling the switches can die. At least on my A2, there is a stored error saying that the signal from the switches is intermittently unreliable, and I have actually seen them work weirdly a couple of times.

    A2 1.4 Petrol dogbone mount bolts

    A question to anyone who has replaced their dogbone mount (pendulum mount) on the A2 1.4 Petrol. The mount has three bolts, one attached to the car and two to the gearbox. I have been unable to understand what kind of bolts are the two in the gearbox, as the catalogue shows two different types...

    I've had a disaster :(

    Wrongness alert! According to my current understanding of catalogues, it is actually 8Z0 423 156K and above, i.e. K,M,P,R. Also, note that J,L,N,Q and S are for the 1.2 TDI. Anyway, I'm not vouching for anything, just trying to hint.

    I've had a disaster :(

    At least in my car, it previously had the older type of pump and the separate sensor. Then it had a crash with the previous owner, the pump was replaced by a newer one, but the sensor remained plugged in. When I unplugged the sensor, the pump being the newer type, continued to work perfectly. My...

    I've had a disaster :(

    There are three connectors on the pump: CANbus, power and steering angle sensor. On older A2s, all three connectors are used. On newer A2s, the steering angle sensor is not used, instead the steering wheel data is supplied across CANbus. Older pumps are incapable of receiving data across...

    Drl

    The "No" is because the Up sidelight in DRL mode is 21W, while the A2 sidelight's maximum power is 3W, or you will burn the headlamp. You cannot fit a LED powerful enough for anyone to notice it during the day. If you do want to avoid fitting separate DRLs, another approach sometimes used is...

    1.4 petrol Thermostat part no.

    I apologize for (slightly) breaking into this discussion, but I would also like to join this question, even if this is not the solution to the OP's problem. I will soon be changing the thermostat (due to doing some other work, as it will then be easy), and I am also confounded by those two...

    2001 A2 1.4 AUA LHD 83000 miles Oil leak from undertray/sump?

    Cleaning may be a bad idea, at least on some other cars with similar engines the oil separator has later "disassembled its innards", they fell into the sump and (partially) blocked the oil pickup.

    1.4 Petrol Misfire (P0303) - Help to diagnose?

    I can confirm that when my engine is warm (2000 AUA), tickover drops to about 600 without air conditioner / 800 with AC.

    Changing shock absorbers

    One note about the rears, read it here somewhere but not in a main thread: it is rather easy to crossthread rear top mount bolts, so be careful and double check. Can the brake reservoir be moved without disconnecting anything (hoses, wires etc)?

    2001 A2 1.4 AUA LHD 83000 miles Oil leak from undertray/sump?

    I just replaced the oil separator, symptoms as described (to the back of the engine). Also, rather a lot of oil had gone quite far as quite a lot of rain splashes into the compartment and then carries it further (also, being oil, it "sticks" to surfaces and can migrate rather far). Also needed...

    Can I replace a steering rack with G250 with a steering rack that does not need it?

    In case this is of interest to anyone. After prowling ETKA for a while, I could not find any change that was simultaneous with the change to rack with no sensor. So even if there was a change, it must have been earlier. I had ABS MK20B, the sensorless rack change happened while MK20B was still...

    Can I replace a steering rack with G250 with a steering rack that does not need it?

    Thanks. This shows that the existing pump already is attached to CAN. The newer models simply have the G250 connector blanked off. Apparently, they simply use the G85 signal from CAN. Therefore, unless there is some other component that is "in the middle", it should just be possible to plug the...
