Thread: D4 windscreen wipers - different codes - which one?

When I last replaced mine l found that they were different lengths. I was replacing the original fitted blades so that presumably is normal. I used Bosch and they were indeed different lengths too. Surprisingly the driver's blade appeared to give 1 to 2 cm less coverage than the original despite the doco saying it was the same length as OEM. Must get a new set, it's been a while.

Thanks Martin, I’ll check to see the way I set it up. I think I may have done it that way, well 50% chance anyway. I have full wiping coverage so even if back to front it still works ok.

Some people, me included, have had trouble with a knocking noise after blade replacement. Mine happens when the blades are at top speed mainly. The blade is not hitting the A pillar but the arm apparently becomes twisted.

Here's a thread that you may find informative in case you strike that problem.

Purely out of curiosity, if you check the Land Rover Discovery 4 manual it sets out a procedure for changing the wipers which involves switching the ignition on and off and pressing the wiper stalk in a specific way so that the wipers move to a "service position". Presumably the wipers move to a position mid-way up the windscreen.

Has anyone here ever used this service position procedure?

No, but it would make it easier I presume. Hadn't heard of it until now.

This be it...

Actually the front two appear to need to be the same length - that's how the online suppliers provide them.

When I bought my last set they were different lengths. Maybe they've simplified things and made them the same. I just looked at my old e-mails and the advice from Bosch Australia was that the BBA530 was the passenger side and the BBA550 was the drivers side. The difference being 20mm. I don't really think it would make much difference.
