Ignition problem

[bytheway]

Hiya,


Can anyone help me on this?


Quite often when I turn the key to start the engine, everything disappears from the dashboard display and the starter motor doesn't even seem to be alive. So basically I can't start the car. As the battery would be flat, but it's a new one and the multimeter says its on full power. Any help would be appretiated

Cheers

When it does this, does the mileage reading display go blank to ?

What year car is it? What engine?

Could possibly be the ECU control relay....

Its a 1.6i in a 1998 Cordoba.

Yup, both the milage and the clock dies completely and don't even come back. I can't even jump start it with the external battery. It can be bump started though and then the display comes alive again.

It does it every morning. What I do to avoid it, I disconnect the battery every time. Then it starts.

Worth trying the ECU Control Relay, had a similair problem on my '96 1.6 SX, it would constantly cut-out whilst driving with all the clocks etc going blank.

I think the relay is about £11 from Seat/VW. It's the one with '30' on it on your fuse board under the steering wheel.... take it in to Seat and ask for another one, they should be able to get the Part Number of it.

Here's the part number: 165 906 381

thanks for that! However there is no #30 on the relay panel. Or I can't see it. Probably it's another layout? I wouldn't have thought there is any difference between a '96 and 98' panel though...

 

[andyj]

Hmmm..... it might only be the 1.6SX that has it then.....

Not sure other than that mate.

Might be worth seeing if you can get it checked on vag-com for any fault codes etc. Where are you based?

 

[bytheway]

Hm. Thanks for that anyway. I'll try to get a layout diag to see if where it's hiding...

I am in Bristol.

Cheers
