My mother-in-law has the same car as me - 1.6 sxi, just over a year old now and on its second EGR valve.
Its been back in 5 or 6 times now due to juddering and hesitation on acceleration. They've (Vauxhall) have either cleaned it out ot replaced the whole unit!
Last week it went back and had its second valve, along with the explanation of 'cheap' supermarket petrol being the main reason for its malfunction!
Now, and I'm no mechanic, surely any modern engine management system should be able to cope with differences (up to a point) in petrol grades and standards! So is this a typical fault or an indication of there being something else wrong?
My car is over 2 years old now, and due to ASDA's points card offer they had ran exclusively on their brand for over a year!! I had no problems what-so-ever!
Is it a driving techinique thing??
Admittedely(????) I do boot mine, and I think shes does perhaps 'tootle about' a bit! But even so any modern car should be able to cope with all driving techniques???
What do you think??
