Hi
My 560 came back from the independant 'menders' today with a buzzing coming from under the passenger glove box. I unscrewed the footwell cover and underneath there is a little electric motor with a fan on the end which has a hose disconnected and the pump was detached from its mount. The pipe has a split so doesn't attach anymore. I'm wondering firstly what the pump is, is it vacuum and secondly why they were working under there. Is it because the ecu is under there and they needed to connect to it for servicing? It was in primarily for a service and to fix a misfire.
The car has come back with poor performance, severely underpowered and with a worse misfire than it went in with. They had the plug leads off for new plugs and maybe that has damaged the plug leads. It is an old car so i'm trying to be fair and understand what might have been going on before i take it back tomorrow.
Any help much appreciated.
Cheers
Mark
