Anyone know the location of the Fuel Pump Relay in a Toledo/Leon?

[dan83]

Hello,

Can anyone tell me where the fuel pump relay is located on an 04 tdi Toledo? I've found a small relay box above the MAF near the windscreen, but there are only 2 relays in there. Not sure if one is the correct relay to replace. The number I have on the part that has arrived is 643 but the number on this relay in place is 100. I've read that the fuel pump relay number should 109 tho lol so I am a bit confused. Can't find an owners manual for leon or toledo. Any help would be much appreciated. Thanks

Dan

the panel under the steering wheel, remove the screws holding it on and they are in behind it

Thanks a lot mate, I'll check this out tomorrow. Much appreciated

Has anyone replaced this relay before? The relay (number 109 I think) has now been superceeded by relay number 643 which I ordered from Seat but the pins are in different positions so one of them is not actually connected to anything when plugged in. They said the part is correct having given them my reg number, is this part for the newer model Toledo or something (mine's a mark2)? Anyway it doesn't work. I think I will just get a 109 from a scrap yard or something, bloody easier.

I'm not sure which relay number it is hehe. Wish there was a manual for this car. It looks like 109 is for the main power supply. 100 is load reduction relay and 53 is for windscreen wipers etc. Any idea which number it is or will it be 643 as it is on the new part? Can't see a relay with that number on it. Sorry to be a pain/idiot

 

[jiege01]

whats the part number of the new relay? according to etka, 167 is for the pd engine and 109 is for the non pd engine

 

[dan83]

The part number is:
8K0 951 253

I've had a little search on that site and it didn't bring anything up

 

[jiege01]

i still think the relay is numbered 167 and is in location no.10

 

[dan83]

ok thanks. The only relays I could see behind the panel under the steering wheel were 53 (x2), 109, 100, and I think it was 273. The last one looked completely different it was larger than the others. The replacement they gave me is numbered 643 though, I would have thought they would number it the same even though it's a new version of the part. I'll take another look tomorrow

Position 10 is the middle of the second row of relays. My references show it as a number 53 relay, same as the horn relay (position 1 on the lower plate, lefthand end of row 3).

Thanks mate, still havent had a chance to do this. I'm sure I tried it in the place of relay 53 tho. Couple of questions:

There were two relays numbered 53 does that mean I need to replace them both? (vag-com told me there was an intermittent short on the fuel pump relay)
What reference material are u using? I'd like to get hold of it

 

[Muttley]

I think the number 53 is a type number or stock number for that particular type of relay, defining contacts, current ratings, pin layout and etc. If it is the fuel pump relay that is at fault then you need to replace the relay in position 10, whatever number is on it.

Reference is Elsawin.

Thanks for your help mate, I've replaced it and it's fine

I have a toledo 98 and wonder if you know where can i fine the FPR in the relay panel.

Thanks

All I can say about the Mk.1 Toledo is that it is apparantly based on the Mk.2 Golf, and although I used to have one of those I don't have the Haynes manual around any more. All I can suggest is to find out which one of the Mk.2 Golf manuals is relevant to your Toledo (you don't say what engine it is) and go from there. Sorry.

Thanks for your reply, i am not sure what engine i have but i discovered lately that when i start the igniting and before cranking the FPR does not funktion and the motor do not start. it would start with a aboute 2 sec and cut off if i do not crank.
What could be wronge that it does not supply the FPR with 12v ?

Thanks

Well, is it a diesel or a petrol engine? That will give us a bit of a start

Can you describe what you're doing and how the car reacts? From what you say, you're trying to start the car and it won't go at all? That sounds most like an immobiliser issue, car not recognising the chip in the key. But it's difficult to be sure from your description.

If you don't know where the fuel pump relay is, how do you know it isn't getting power? Or is it the fuel pump itself that isnt' getting power?

Okej, it is a petrol engine, accedently i descovered the FPR, here is whats happning, for a while ago about 1 year the car began to cut off totaly like you turn off the igniting all the lights are on on the dashboard and was very easy to start again, with the time it began to not start sometimes and that was the FPR which does not getting pwoer when i turned on the engine AND tried to crank, i tried to push the relä manuely just to see if there is the problem but it did not help, the FP goes fine but it will not start,now seems like the ECU ´does not get or miss the trigger from the triggersensor,
sorry for my bad english , help a poor seat lover.
Thanks Muttley for your time

Well, this is the diesel section of the forum, so you aren't in the right place, really. You might get some answers in the Toledo section. That is the most likely place to find another Mk.1 Toledo owner, for sure. However the Toledo section has less visitors, reflecting the lower number of Toledo's out there.

If I understand you correctly, you have now found the fuel pump relay, is that correct?

for a while ago about 1 year the car began to cut off totaly like you turn off the igniting all the lights are on on the dashboard and was very easy to start again,

Again, if I understand you correctly, the car is just cutting out. Does this happen while you are driving, actually in motion on the road? Scary.

When it cuts out, do the lights on the dash stay on or all go out?

How do you get it to start again, by turning the ignition all the way off, then back on again?

with the time it began to not start sometimes and that was the FPR which does not getting pwoer when i turned on the engine AND tried to crank,

Are you using an electrical meter to prove that the Fuel Pump Relay is not getting power, or just listening for it clicking?


i tried to push the relä manuely just to see if there is the problem but it did not help, the FP goes fine but it will not start,

If I read this right, you tried manually closing the contacts on the fuel pump relay (Bold - must have the cover off and know just how to apply the screwdriver to close the contacts without shorting everything out).

When you do this the fuel pump works but the car still won't start.


now seems like the ECU ´does not get or miss the trigger from the triggersensor,



Well, I think there is something more than just the fuel pump relay at fault. But it is hard to work out what.

I think that if you can get the car diagnosed using VAG-com or something similar, to find out what fault codes are being raised, then you can maybe have a chance to find out what is causing your difficulties. A Seat, VAG or good independent dealer will be able to plug your car into their diagnostic equipment, but is likely to charge you for doing so. The alternative is to find someone near you who has VAG-com and a suitable lead and who is willing to come and help you.

Where are you located?
