Hello everyone... It has been years!!! Hope everyone is doing well
I come on here for some advice, I have recently got my car back after a while as it was rotten... Like really rotten. Everything is sorted now but I have some issues...
My wipers work except for the intermittent wiper option. They will wipe once and then nothing, doesnt matter how often I set them to, they will not wipe again until I take them off this setting - I have had a look at the timing control thing near the drivers side fuse box and the green relay there. All looks good, no bad solder etc. I have changed the blue ACC relay at the back of the fuse box, still not working
The washers are not working either, push the button and the motor does not work, the wipers dont move with it either and the low fluid light is not coming on at all
Any help would be most appreciated

For a while now my z has had an issue with running when cold.
It was partly solved when I had the aav replaced, but not completely.
The garage that did the work said that problem may be down to the ecu?
I did borrow a ecu and try to see if it made a difference but it didn't.
I'm starting to think that the garage didn't realize the zed had a separate ecu for the fuel pump and was wondering if this may actually be the issue.
Before the aav was replaced the revs dropped right down from start up.
Now it last for about 30 seconds until the revs drop.
Once the engine is warm, it runs fine.
Also, I've notice that the fuel pump is humming louder when the revs are low.
Question is...
Is this issue down to the fuel pump ecu or the fuel pump itself? Or is it something completely different?
