Oh R230 gurus of this forum.... can you help?
Just as I'm thinking about getting an SL63 my SL500 (2003) has started playing PSE pump weirdness
The normal central locking, boot close problems. Pulling the 20 Amp fuse, which wasn't blown, reset it but then it all stopped working again.
I took the car to a local indy and they couldn't see the PSE pump on the CAN bus and told me I needed a new PSE unit at £985
As the pump was only intermittent, I brought the car come and took out the PSE pump unit to have a look on the bench. There was no sign of corrosion or damaged components and putting 12V on the pump motor made it spin and suck/blow.
Reconnecting everything up again (including reconnecting the batteries) it all worked perfectly.
Two days later without the car being moved or started it was still working (central locking worked) but today it's all gone wrong again How on earth does this fail when the car's not been touched?
Does anyone have
a) any suggestions
or
b) a PSE controller board I could buy? (If I change the controller board does the car have to be 'taught' to recognise the replacement?)
I know the physical pump is working so I think it's something electrical/electronic; hence the idea of just putting in a controller from a unit that's blown it's pump vanes.
TIA
