Audi S4 Spark Plugs Replacement

Hope I’m not being too dumb with this question ... I’ve just had my S4 through its second service at 35,500 (ish) miles and the dealer suggested I might want to change the spark plugs as they are due at 40,000 miles. I was then quoted £330 for them to do this. I declined whilst I did some thinking and asked around at other dealers. Is it only me that’s thinks this is outrageous?

Thanks Darren. Was thinking the same but was wondering if there is any risk of causing damage if it’s done badly. I was also wondering about doing myself ... I’ve looked at several videos of b8 spark plugs replacement and it doesn’t look too difficult. I don’t have a torque wrench though and removing some of the kit around the plugs to provide access looks a bit messy.

Spark plugs are bread and butter to mechanics. I would suggest getting an Audi specialist to fit them given how new the model is. Definitely buy the plugs from the dealer or TPS though, 2 year guarantee with them if bought this way.

If you do go down the independent fit road you need one that has access to the Audi factory system to update the fact that your car has had replacement plugs installed. Look on the bright side the - the 5Pot RSQ3 I had prior to the '4 needed a new set of plugs every 20,000 miles. They were made by Beru, could only be bought from Audi and were £200 a set+labour. Did go like the proverbial scaled cat afterwards though:flushed:
