1) Yes Dave, when I last stripped the tank out to replace one of the pumps some 4/5 years ago it and all the pipes were sparkling clean after Oxy treatment. More recently I have had to unblock the jets much more often. I have a length of suitable pipe to assist soaking the engine bay.
I have also noticed that even my spare top-up bottle stored in the garage out of the sunlight now develops floaters after a few months. I think the 'blossom' must settle to the bottom of the tank where it is immediately picked up by the pump suction like it does in my top-up bottle. The trouble is that you cannot tell what's good or bad these days. I have always used one make of concentrate (CarPlan I think) which was fine until a years or so ago but that's now a problem. 2) Also thanks Jebus ... I always like a slug of meths before I fall off to sleep! What you say confirms my thoughts that the current stuff is crap and unfit for purpose. I was wondering if something could be added to the modern stuff to prevent the problem, or a formula devised to make up some home brew. Bob |

Perhaps methanol and Flash multisurface cleaner for the detergent.

If you don’t want anything complicated. You can just use the skandix interval relay
https://www.skandix.de/en/spare-part...wiper/1020840/ I wouldn’t want any loose relays in my relay box |

You can see the "99" relay in the bottom of my relay board.

Just FYI, Did mine today. Took me a while to sort out the pins. I Used an old relay socket froma scrap car so I could test things out.
Those who want to replace the rectangular wiper relay with 6 big pins, Will need to fabricate a little harness to piggyback the relay on. Pin out as follows Volvo Socket VW Relay 99 31 ------------------ 31 31b ----------------- 53S I -------------------- I S -------------------- 53M 86 ------------------- T 15 ------------------- 15 Enjoy your new washy wipey. Can someone update the tags in this post so google can find it? Volvo 940 vw relay 99 wash wipe volvo 740 vw relay 99 |
