Just had a call from my dealer, who is carrying out an oil service on my Superb iV.  It's done about 21000 miles, mostly on electric power.  They want £116 to replace the spark plugs (they're 'due' for replacement) .  Is this a particularly tricky job?  Are the spark plugs particularly expensive, bearing in mind this is a 1.4 litre engine?  I'd be happy to do it myself, but wondering if I've missed something.  They've also advised that the tyre sealant needs replacing as it has expired - a cost of £61.  Again, this sounds like something I could source myself, or am I missing something?

I thought spark plugs were at 40,000 miles according to Skoda's own regime (granted 4 years but if the cars not doing the mileage they won't deteriorate)?  They're about £15 each tops from memory.  Ideally you'd need to remove one and check its condition before stumping up for replacement.

 

As for the tyre sealant - bugger that at that price!  Anything from £10 - £20 on ebay or similar for OE stuff or less for universal stuff.

yup, buy your own sealant, or sealant and emergency “ worm” repair kit as well - the above recent thread may be interesting.

The Spark Plug Recommended Service Schedule for changing is at 4 years or 40,000 miles. 

But then the Recommended Service Regime for a PHEV is oil & filter changes at 12 months / 9,400 miles.

 

PHEV,s might run almost only on Electric, or maybe never and just using the engine and owners might leave the Oil changes on Variable / Flexible, 18,000-20,000 / 24 months.

 

This is an issue with PHEV,s   I would not leave a Air Filter for 6 years / 60,000 miles and i would look every year at least and change if needed. 

 

If you can remove the Ignition Coils and remove the spark plugs then do that and see.

If i was doing that i would put in new plugs anyway.

 

Skoda /VW PHEV servicing is really Money for old rope for Franchised Dealerships. 

 

DQ400-e DSG service is due at 40,000 miles or sooner.
