200 cold start problems

[Geraint Lloyd]

Hi,

sunday morning,

still have the starting problem......

ARSE

I will pull codes in the week.
and attempt to leave the car overnight with the
pressure gauge attached

I do have the classic ' hall sender plug held to the
dizzy body with
zippy ties' issue.
I might just swap that anyway. looks like ETKA lists
the sender for the
200 as not available separately
I 'll call my Bosch dealer mate in Wrexham and see
what turns up.
