Thanks for the replies.

You could also disconnect the ecu and then check the 5v at pressure sensor. . If it’s still 12v the wire has shorted some where.

Otherwise it’s the ecu

Great idea. I'll test this.

Hi matchermike

Hope I’m not sticking my nose in as I know the guys here are extremely knowledgeable and can guide u better than myself

But was wondering if these links may be of any use to u

Not at all thanks for the links. I'm slightly nervous i've bitten off a little bit more than i can chew, but i love the car so really want to get this sorted. I'll try anything and everything anyone can suggest to resolve.

MatcherMike, you only get voltage at fuse 3E when the relay operates, so if relay is not operating then no volts. Have you tried swapping the relay as they are known to fail Embarassed

Thanks for the suggestion. I've swapped the relay and tested the socket. The ECU isn't sending voltage to throw the relay.

Will check my voltage on front height sensors and pressure sensor once the ecu is disconnected.

Thanks
Mike

Hi mike

Glad it’s of some use, know it can feel like ur tearing ur hair out sometimes , god knows I’ve been there when I had a battery drain

The kind Pete k along with Robbie and many others helped me all the way through the system and finally found the issue ( I had retrofitted front electric seat , memory ecu was the error , removed the seats wiring and ecu , , made a new loom and new non memory switch pack, sorted )

My battery from fully charged will last just under 3 x weeks

Good luck mike and maybe it doesn’t feel like it now but with the great knowledge pete has and working through the system step by step ur get there
