Ok so I posted recently about an issue of a 2001 C220 not starting.
The car was collected and my local merc specialists took a look. Seemed as though there was half an inch of water sat in the ECU and below Sam Unit. All the connections in the ECU had corroded.
However, they took it apart and stuck it in their airing cupboard overnight and now it works! So I got lucky this time.
But my question now is how on earth could water have got in there. I presume it cant get in from below and even with a downpour water wouldn't get under bonnet and run over the Sam unit in its location at the back of the engine bay.
Has anyone seen something like this before?
