Relay 98

[davetee]

Does anyone know what relay marked 98 does on a 2001 X reg 1.9tdi zetec galaxy AUY engine code 115bhp.

 

Its buzzing loudly and not charging the battery when I remove it the battery light goes out and the battery charges?

 

It is positioned level 2 marked number 19 the manual says 19 is not used the relay says otherwise?

 

 

Thank you

I "think" 19 is the glowplug relay, I'll have to confirm that for you (if nobody else has) sometime next week though.

That would be great I have removed it at the moment it is charging fine but I would like to know what it does I shall try and get a replacement asap as it is probably at fault.

 

Thanks

Hi there

Just a thought, you said previously that 19 wasn't used on your model, maybe some aftermarket accessory has been added using that relay.

Is there anything obvious thats not working now!!

Hi Davetee

Have found this relay 98 in slot 19 in the sharan wiring diagram.

The actual text says "Release relay for terminal 61, Additional water heater coolant circuit valve relay, looks like this year model had a shut off valve in the water circuit.

Hopefully Mark will confirm and may have additional info. Hope thats of some help anyway. :rolleyes:

Hi, I have exactly the same problem. Same vehicle (italian version, I'm from Italy, which means it has a different name but it's basically the same), same engine AUY 115, same relay number and position. I found it making a "click-clack-click-clack" continuous noise after changing a faulty alternator, just to find that alternator does not charge when it's making noise, and that it burnt the new alternator mounted after a couple of days. Removed the relay, all is working fine.

 

I mean ALL! All electrical stuff, clima, dash, heater, lights, fans, cigarette lighter, all works fine EXCEPT the additional heater which I have no way to try out, because it's not cold enough!!!

 

I've spent my time on it for a few days, and found out that the pin 30 of the relay, which should be the "Connection (61), in dash panel wiring harness", has 12 Volts when the dash is on... and the relay connects the pin 30 with the 87, which is ground... short circuit and alternator not charging anymore. But have no idea where the wire number 30 goes... elsawin and tis have no clear diagram, and you already know it's not supposed to be there...

 

So, did you find out what was the problem? I'm tempted to leave the relay removed forever... :D

 

PS sorry for my English, it's the best I can do!

Hi there

Have you done a diagnostic check to see if there are any fault codes on the system,may help with diagnosis.

In the elsawin diagram relay 98 (J 574) has a diode which could be faulty allowing currant to flow wrong way and is linked with alternator and additional heater.

Hi, thanks, no fault code at all... I will check the diode, but i'm pretty sure it's ok, in fact the relay itself does work, the issue is that it links tho wires one with Vcc and the other with Gnd. So I guess the problem is the circuit after the relay, maybe the (in)famous connection 61!

 

PS just changed the fuse box near the battery under the bonnet, with the main wire which goes to the interior, to the GEM. It was melted, and the wire was far over 100 degrees!

Just tested the diode - it's ok. By the way, removing the relay on the slot 10a, besides the relay for dual horn (i believe it is J586 "Temperature switch relay (additional heater)") there is no more 12V on pin 30 of relay 19... but it continues to make noise! :D

Hello! So, for anybody could be interested, my problem turned out (hopefully) to be the alternator itself. In fact, after 1500 km the new alternator broke down, too. Replaced with another one (same model, bosch)... the relay is not buzzing anymore. So far it has run for about another 1500 km, and it seems to be all functional ("toccando ferro", is it "touch wood" in english? :) ) . The relay 98 was there because it was supposed to connect the second battery (under the passenger seat) to the auxiliary heater. But for a few months it was fitted also in cars without the second battery (like mine), in that case it connects the main battery circuit. The clic-clac could be due to the fact that the blue wire coming out of the alternator (the Terminal 61) has no power to keep the relay steady, or some similar issue.

 

Hope it can be useful! :)
