A4 1.8T SPARK PLUGS - D NEEDHAM
THE AUDI A4 HAS SERVICE INTERVALS OF 40,000 MILES BETWEEN PLUG CHANGES , IT WILL TAKE ME FOUR YEARS TO REACH THIS MILAGE , WILL THEY BE A PROBLEM REMOVING THEM AFTER THIS TIME , ON PREVIOUS CARS (NISSAN PRIMERA'S) I'VE REMOVED THEN EVERY YEAR REGREASED THE THREADS , CHECKED THE GAP , GENERALY INSPECTED ECT. A TEN MINUETE JOB. HOWEVER WITH THIS CAR I'M NOT SURE HOW TO REMOVE THE PLUGS FACED WITH A SEPERATE IGNITION COIL OVER EACH PLUG SO IVE LEFT THEM IN FOR THE LAST 18 MONTHS , BUT WOULD I BE BEST CHECKING THEM ? AND IF SO HOW DO THEY COME OUT

I think that this might be one of those occasions to use the old saying, " If it aint broke, don't fix it". Plugs are probably platinum tipped, so wear is less. I've experience with the old V6 Toyota Camry that had I think 60,000 mile intervals, and they came out OK. The price of the new plugs was the real downside.

I always use a carbon/graphite powder on threads. Grease evaporates but not sure if Copperease(for back disc brake pads) would do the same job.

If all is well then leave well alone.
The spark plugs are indeed platinum tipped, far more wear resistant than the normal copper types.
Spark plugs in some MG Rover models today are designed for 90 000 miles.
Technology has caught up with the humble sparking plug it seems!

Be very, very, careful....if you are like me (ex-mechanic and mechanical engineer who likes to service and repair his own car). Four years ago I bought an Audi 80 16V (ex-lease) on which the plugs had never been changed at 45,000 miles. When I tried to take them out, the middle two just turned and turned (yes, I WAS turning anti-clockwise). This entailed taking the head off and getting thread inserts put in - a real pain of a job in the average home garage full of lawnmowers, bicycles, etc. If you still use an Audi or specialist dealer for servicing, I would suggest that you let them do this instead!
