Thanks Gatos, my feelings exactly! Why would anyone disable main beams?
don't think the wiring loom under the rad is at fault, main beams work on my original CEM.

Just discovered CEM is from a 01 V40, is this a problem?

No it shouldn't be a problem. THe only difference between the S40 adn V40 is that the V40 CEM is programmed for the rear wiper. However I have tested and confirm that with VIDA and DICE, you can program an S40 CEM to utilise the rear wiper as well as enable/disable the fog lights and some other functions.

Tell the buyed you want to return this CEM and that you want your money back. The description of the item was incorrect. Even if what he says is true, then Volvo would charge you a fortune to reprogram it. I also have a CEM in case you still need one. I have tested it on my own car and everything works as it should.

Many thanks Gatos, you have confirmed my suspicions and also answered my next question, i.e cost of reprogramming. I will return the unit and demand a refund. I would like to buy your spare CEM, how much do you want for it?

I normally sell them at £30 plus postage. However, in case it does not solve your problem, then you can of course return it back with no questions asked.

I will also need you to confirm what your car has on it, so I can program the relevant values. In your case, you have a 2002 S40 1.9D, so rear wiper is out of the question. However, I need to know if you have front fogs or not. Or I can program it with fogs in case you don'ts have any and would like to add them in the future.

That's great, Gatos.
Please program it for front fogs, I dont have them but would like to fit them,
are they difficult to fit? do you happen to have a set?
Can you take payment via PayPal? if not I can post you a sterling cheque.

They are fairly easy to fit I guess. I have them on my car, but I hardly ever use them and find them pretty useless.... lol. But a lot of people like them. Paypal is fine.

I don't have a set of fogs, but Siamblue has one, so you can ask him. He leaves down the road from me, so he can drop them at my place and I can send everything together.

You will also need the headlight switch with the fog lights buttons on it, in which case, I have it for a tenner

Hi,

I'm new here, I got the problem with my dipped head light on both sides, just one day before the scheduled service... good timing...
it is a v40, 2003.
when i took the car to service, the dealer just said this was because of replay in the cem box need to be replaced. Based on there was no voltage on the headlight socket, the fuse in the fuse box was ok. If I replace the new cem box, costs more than 4000 sek... Sorry forgot to mention I'm in Sweden.
So I took the car home, opened the cem box with the wires on and test with voltmeter. Please help me to see if the replay is working. Because I'm so lost and give the basic physics to my teacher :-P

when the key is off,
the voltage between com and NO is 12.15 on both sides

when the key is on
and light switch on
the voltage between com and NO is 11.90 on both sides.

Are these relay working? or the contact got oxidized? Thanks!

Problem finally sorted, new CEM from Gatos works fine. Thanks to Gatos and SiamBlue for all your help.

Lesson learned, beware of "fully tested " spares from FleaBay! Dodgy CEM returned for refund. I will source all my spares on this forum in future.
