Delay wiper upgrade for 850 / V70 models

Post by **jblackburn** » 04 Feb 2012, 08:07

The pause time doesn't reset unless you switch the car off. I do it the way JRL said - I didn't even know it worked the other way.

It really is one of the best small improvements you can make to one of these cars. It rains SO MUCH here in the winter.

I just moved the delay relay from the wrecked wagon to my other one. The relay I have is made by KAE (Kaehler) and only programs the way I described. Probably the more common Bosch relays (Bosch: 0 986 335 058, like the 99 relay from VWs and that IPD sells), only program the other way like JRL describes.

eBay or a junkyard is usually the cheapest source for the VW part.

Just picked up a wiper relay out of an old VW Passant wagon from the jy and installed it today. It was one with the 99 on it. It works great. I have semi small hands so I didn't have to remove the kick plate like iPd recommended. I just pulled the relay 204 on the corner, then removed the wiper relay 203. I was able to install the VW relay by feel, however, my car had NO relays in the 202 slot (not sure what that slot is for).

Once installed, I did like JRL said, on and right back off, then on when needed again and it kept that dime delay. One thing I did notice is that I WAS able to reset the time when I turned it off for longer than 5 seconds. Which is good.

While messing around, I learned that the wipers do work with the relay removed. The only thing is that they do not intermit nor do they park. So if you have wipers that do not park, you may have a bad relay.

Update in the wiper relay that I got from the jy.

It rained all day today and I had lots of fun messing around with the relay. To set it I turned it on and off real quick, then when it was time to wipe again I just turned them on and they kept that delay. It gets better... When that delay wasn't good anymore I simply turned it back off and when the time was right I turned it back to intermittant. Well, it kept the new delay time. That simple. I changed the delay time several times, simply by turning them off and back on. Very nice!!!

Flip the wiper arm up then rignt back to off, then start counting, when you hit the desired time, flip back up.
Works the same

I just bought one of these and was about to install it but I don't see any relays under the dash. I checked the users manual and there is no fuse/relay which have a corresponding '203' under both the main fuse/relay panel and the other location next to the fuses. Am I missing something or are these NOT compatible with the 2000 V70R models?

They're there. Crawl in, stand on your head, and look above the brake pedal. Removing the kick panel may help you with room a bit.

Thanks, I got it done!

If you have large hands and the relay crate is full which is dependent upon the spec of the car then there is an alternate way to approach this job, you can swap the relay out from working stood up at the side of the car, Note the pictures are of my UK spec V70 MY2000 for a USA car the fuse/ relay box will be on the other side of the engine bay, Eurocar parts are UK only AFAIK (pollen filter in the text):

Start by prising the caps of the wiper arms:

Which reveals the 13MM headed bolts:

once removed the wipers can be stored somewhere safe

Next is to open the bonnet for servicing rather than just the normal open position, If you look close at both hinges you will see a portion in the middle with a slot in it:

Push this downwards with your thumb or a screw driver, it doesn't take much force to move it to here:

With the above done on both sides the bonnet will now open to near vertical:

Disconnect the scuttle panel drain tubes on both sides, gas pliers make easy work to squeeze the clips ears:

Allowing the pipe to slide down and off the plastic panel:

Next you take the top cover off the fusebox, if you don't do this you won't get the scuttle panel out as it fouls on the cover during removal, four T25 head captive bolts and it simply pulls off:

There are six T25 screws securing the scuttle panel to the car, simply remove these and slide the scuttle panel down and away from the base of the windscreen, at the base of the windscreen is a slot that the scuttle panel sits in:

While you are in there swap out the pollen filter as a replacement from Eurocar parts only costs £7:32:

Quite a difference when you look at the new one in place:

Now to get to the relay you want to change, firstly remove the windscreen wiper motor mechanism complete, it is only secured by two 10MM headed bolts, the electrical connector is easy to release:

With the wiper assembly out of the way cut through and discard the tywrapps securing the harness that runs across from one side of the car to the other, this releases the harness so it can move away from the clips it was secured to, doesn't need to move far.

Remove the four 10MM head bolts that secure the relay/ fusebox in to the car and the fuse box can now be lifted slightly up revealing the L203 relay that you want to change:

If you want slightly more movement release the two 10MM headed plastic nuts that secure the cable raceway running forwards from the fusebox, the two nuts are located on the inboard edge of the suspension turret:

Out comes the L203 relay:

Simply fit the .99 relay in the same place you pulled the L203 out from (it can only go in its socket in one position) then refit everything you took off the car, total time is about 45 mins and that included swapping the pollen filter.

Looks like I need to spend some time cleaning up the engine bay as it looks filthy in most of those pictures! - Mike

Wish i knew about this before, I already remove all my door chime relays as I find that feature particularly annoying.

OK, I know its thread resurrection, but such a worthwhile mod. I'd forgotten what a pain 2 wipes was in smearing the screen on the second swipe after seeing it cleared on the first. I used a VW 99 relay. A right 'cowson' to get to, I gotthe 203 out easily enough, but couldn't get the '99' b^&*(d in. Actually put the 99 in the empty slot to the left of the correct slot. Became a reason to do my pollen filter whislt i was on.
