My 2007 Sl350 R230 has a 'beeping' sound coming from the boot around the PSE pump area. The beeping is every 10 seconds or so and sometimes its quite loud and other times not so loud. I had this about a year ago for a month or so and then it stopped and now its back again. Both doors wont unlock without the key but the boot is ok. Any ideas?

I'd be lifting out the pse pump to check the connections . Possible that a pulsating leak is causing the beep which you are hearing which may be affecting the door unlocking problem.

Check for water as a first step. The PSE pump is encased in thick foam which can store a litre or two.
