Is not good. Must be GL-4.

It's the same system https://workshop-manuals.com/volkswagen/polo-mk3/brake_systems/brake_brake_mechanics/repairing_front_brakes/repairing_front_brakes_vw_i_and_vw_ii_brake_caliper/

Sorry for inattention. Unfortunately the information about the crankshaft is missing from the workshop manual for this engine and for the 1l engines. Maybe it's the same with the camshaft. I don't know if it's connected, but all these engines have aluminum engine blocks. I noticed that another 1.4 engine, AEX, which was built with both aluminum and iron engine block, information on mounting and dismounting the crankshaft is present only in the iron engine block.

Because it doesn't have it. They are integrated in the cylinder head cover and in the cylinder head. AUD-camshaft.pdf

The part no. for RHD is 6N2422893J or 6N2422893K for car with air condit.

You need to adjust the gear change mechanism Adjusting gear change mechanism.pdf

Replace these two fuel filter valve rings if you didn't when you replaced the filter. Observe the position of the colors and be careful when changing them to avoid damaging the rings and the valve.

60 Nm + 1/4 turn (90 °) further Must be renew.

The ALD engine doesn't have EGR. First check the ignition on cylinder 4. It would be useful if you posted the errors as given by the tester.

I only used OEM G50 (this is written in manual) and I haven't had any problems with the box so far. Now the mileage is about 400k km (so about 250k miles) and I did the first oil change at about 200k km. I've changed it two or three times until now, I don't remember exactly. In general, the gearboxes on the Lupo/Arosa wich are type 085 were filled with G50 except for the gearboxes that equipped the 1.4 74kw engines that require G51. Now VW recommend another type G052178A2 but I didn't trust him. Here is a discussion about this problem. If you'll decide to use an aftermarket oil, be sure to use a GL4 or GL4 +, in no case GL5.

It is not easy to remove the oil seal. for this you need one or two thin screwdrivers (about 2mm in diameter), very sharp and hard (the oil seal has a metal ring under the plastic cover, a ring that must be perforated to hang and remove the oil seal). Basic rules: - Must not scratch the shaft (wrap thin layer of insulation tape around shaft). If this happens it will leak permanently. - Fill space between sealing lip and dust lip with grease - Do not touch the screw B. if necessary mark its position, otherwise you will need adjusting selector mechanism Selector finger

Definitely not ignition on, before removing the plug from the ECU remove the minus terminal from the battery . Basically you measure the continuity of some wires not the functioning of a component
