I would'nt have known that , last time I enquired, all I remember was it was shell helix for diesels

I think your are always meant to wait for the glowplug light to go out before starting...I even tried adding a few extra seconds on. Today It started ok, at -1...not dabbing of the throttle required like the other day.

Incidentally I added some redex injector cleaner to a full tank a couple of weeks ago, and added 1/2 a tank of fuel back in since without any additional redex

Just too feedback..as that is how we all learn afterall !

The diagnostic at the dealer indicated Glow plugs, and reportedly 2 were completely useless and the others on the way out.

Ironically this latter part part of the xmas week marked a return to milder weather.

I am not convinced however the problem is completely resolved, the car now fires when totally cold after 3-4 turnovers, sometoimes a few more when there has been a slight frost ( which is as much as we have had)

I am wandering whether to electively change the battery rather than end up paying for another diagnostic and having the hassle of leaving the car at the dealers..as I said before it is just coming up to 3 yrs old, but took a hammering with last year and this year so far ?? as was said somewhere, it was not a dealer fitted battery, and maybe it's just not up to performing as well now in cold weather

what would you do ?

Cheers, as I said I electively changed the battery when the car was 5 yrs old, as my brother had been caught out with sudden battery failure on his diesel mondeo at a similar car age. The replacement battery fitted was a fast fit centre one, no idea what spec, just it had a 3 year gaurentee.. 3 years ago virtually to the date now..

I mainly do a commute to work and back 7.30 am/5pm a 13 mile journey that takes about 40 mins with about 20 minute scrawling, and a cuople of dual carridge way blasts.
