  locations with small kids, on the problem.  I have contacted my local vw garage who when pressed said that they could look at it (this would cost around £100+vat) and if at worst it was the ecu it would cost around £1000 to fix.  To be honest I would be happy to pay this if I

• Ford Focus - Starting Problems 10 Dec 2012 (Forum)
  . I also believe did a ECU upgrade to assist with starting issues, is this correct? Also the heater seems to take an awfully long time to get up to temperature, even though the temperature gauge on the engine is up to normal after about 10-15 mins of casual city driving. I have tried

  and it had blown the ecu and cooked the glow plugs. The bill for their work came to £1200. Do you think I stand a chance of getting compensation from the rebuild garage by going back to them and stating they got the timing wrong which caused the starting issue? I believe my local garage

  it and it did run a bit better, but slow. And after a while it started surging up hills again. Probably not good to run it like that anyway!
