funny you say that
my car went in for its 40k service with a missfire , i knew it was plugs again causing it (my went through plugs at about every 8k miles because they set the timing wrong on my car for 3 1/2 years grrrrrrr , but thats another story) so i thought , no problem new plugs will be fitted on the service.
Got the car back drove away and missfired , checked the service sheet no mention of plugs?
went back to the dealer and this is what they told me " SEAT service schedule for plugs is 60k miles " , i said i dont think so , they were adament , so i said phone up SEAT and i will wait here while you do it , low and behold 20 seconds into the conversation 40k is mentioned.
my plugs were fitted free of charge , but thats not the point the so called "experts" knew absolutley nothing , and i was paying £125 + vat an hour for their labour.
Fortunately (or unfortunately?) my car is under warranty so this should be a free fix....but I dunno how long it'll take!!!!
I will mention plugs and see what they say. They'll probably think I am talking about the plug from the coffee machine, the f**kin mongs
