  and it's really trying my patience. Had to abandon it today and let it go cold, thereafter started easily.

• Audi A4 (1996) 1.8 starting problem 17 Oct 2007 (Forum)
  it didn't play up for them. They suspect something in the ECU, possibly related to a relay in the fuel pump which switches from 'Startup' to 'Running' mode. It's beyond their expertise. Has anyone heard of this relay? Is this a known problem? Problem seems to have started after another garage fixed

• Mondeo Cutting Out 2 Dec 2006 (Forum)
  code reader plugged in but nothing showed up & it behaved itself. With me driving it continued to cut out as on the first day. Garage told me to lock/unlock it to reset the ecu but that doesn't work for me. Shall I trade it in & get a Jap job???! Have just read horror stories in another thread

• Tipo fails MoT on emissions 8 Dec 2005 (Forum)
  , on medium runs. Is there something I'm missing here - say ECU failure? Seems unlikely that the timing is/was incorrectly set (by a professional), given that it's otherwise running acceptably.
