hi going to service the car next weekend. It's got a piper cross air filter in so really just looking at plugs and oil & filter. What's the best plugs ad oil to use in it.and I've been looking at flushing the engine some say do other say don't any info be appreciated thanks.

Use this oil, http://www.ebay.co.uk/itm/Quantum-Longlife-3-5W-30-Fully-Synthetic-Engine-Oil-5-Litre-Bottle-/131453080952?hash=item1e9b36d578:g:NSAAAOSweW5VAFXT

 

And these plugs http://www.ebay.co.uk/itm/NGK33-Spark-Plug-x4-PFR6Q-Audi-Seat-Skoda-Volkswagon-BNIB-/131992293488?hash=item1ebb5a9070:g:Yw8AAOSwx2dYG2pe

 

And this oil filter http://www.ebay.co.uk/itm/Mann-Oil-Filter-Spin-On-Type-Audi-A4-1-8-T-Quattro-Performance-Service-Engine-/231318345475?hash=item35dba5d703:g:aekAAOSwVFlT~mo5

 

I wouldn't use a flush, as long as you do regular oil changes circa 5000 miles it should be okay, does it have good service history and have you ever had LOW OIL PRESSURE warning?

 

Hope this helps, I've had experience with 1.8t engines for over 10 years so any questions just ask.
