To replace the alternator on the Volkswagen Golf VII, first disconnect the battery. The work is primarily done from underneath the car, removing the protective cover and the wheel arch lining.

Loosen the auxiliary belt, remove the bolt securing the tensioner, and move the A/C compressor to the side, disconnecting the plug to avoid straining the cables. Before fully unscrewing the alternator, disconnect the positive cable.

If the alternator is difficult to remove, ask an assistant to gently push the engine backwards (after loosening the lower support) to create the necessary clearance. You can find a suitable Hella alternator for your car on Amazon with code B0BRXPFQ44 for £258.31, with free delivery.

Insert the new alternator, restore the electrical connections, reassemble the A/C compressor, tensioner, belt, and the tensioner bolt to reapply tension. Now comes the software part, using a diagnostic tool to code the voltage regulator in the car's ECU: only after this coding will the alternator start charging correctly.

How to Remove the Toll Tag Holder from the Windscreen Without Damaging the Glass

Removing stickers or tags from your car's glass without damaging the windscreen has always been a problem. Especially if we attach it - as we should - at the top of the windscreen, where the "black dots" are, which is the unshielded part of the windscreen designed for this type of device, whether it be a toll tag, GoPro, cameras, or otherwise. We found this product that seems suitable, specifically designed for this purpose, and it also thoroughly removes dirt, grease, oil, and antifreeze salt from plastic surfaces. You can find it on the ATG website or on Amazon.
