I have a 2010 Fiesta Zetec which I've owned for about 18 months and recently had to call out the AA under the Ford Assist plan as my engine light appeared during the wet weather we had a couple of weeks ago. A good spraying of WD40 was the answer, which indeed did solve the problem, but decided to get it checked out at my local Main Dealer under the warranty plan.
I've just had a call from the garage and apparently it just needed a new spark plug as the ceramic had cracked on No. 2.
They told me that the spark plugs are due to be changed at the next service (third year) which apparently is normal, but as one is cracked, they will change all four of them at a cost of over £69 as spark plugs aren't covered under the warranty plan.
Does this sound right to you guys? I don't know a lot about engines, but I always thought spark plugs should be changed at every service and just assumed they were changed at my last service in October.
Looking forward to your comments.
