Hi all,

Just started my cupra, got 3 beeps and red coolant light on, along with no revs or speedo showing?

Any ideas on where to look first?

Had a quick search maybe points to Ecu?

Any help appreciated

Thanks all

Coolant is ok? Now noticed it is running ****, boosts okish in 2nd then won't pull in 3rd to 5th turbo and dv sound really loud too?

Can this all be linked to one fault?

Help!

Update:

Had the ecu out, no sign of water ingress, so put back, all fuses checked and are ok, topped up coolant even though it wasn't low, still same,

Symptoms are:

No Rev counter
No speedo
3 beeps and coolant light after 15 secs
Fuel gauge fluctuating
Not running properly

Also no reverse lights or brake lights?

Somebody help!

Checkt your engine fault codes with VAG-COM??
Sounds to me like a failed groundspot

Does sound like a dodgy earth,, check your straps, the one of the battery to chassis, there sometimes another strap , gearbox to chassis, check them both at either ends,,

Is your engine light on?

You need to get it on vagcom, that will point you in the Wright direction

Multi plug connector slightly off under dash behind fuse box, not sure how that's happened?

Clocks working now, only boosting 11 psi where as it was 16 psi, so need to check maf, n75 and vac pipes.
