991 TT Spark plug Change

[Mijostyn]

Hi all,

It has been a while. Anyway My TT is over 5 years old now and although it runs like a top a Spark plug change is recommended on a time basis. The car only has 16K miles on it.

I'm also supposed to change the PDCC reservoir. I'm not even sure where the pump is. I most probably have to take the rear bumper off to get to it.

The spark plugs are being blocked by the turbochargers. You can get good access by removing the rear wheels and the rear wheel well liners but do you really have to move the turbos? Or, is this just a mater of juggling extensions and scraping knuckles?

I was under the understanding that the engine needed to be lifted slightly to get access to the back spark plugs.  My 2015 TT has 14K miles.  I plan to wait until the car reaches the 30K mileage mark before considering the spark plug change.

You do not have to move the turbos or lower the engine

I did it and while it was a challenge it was very very doable

if you guys are interested in maintaining your car correctly you have to be aware of the time limits

spark plugs are four years or 30,000 miles

So you have five years on your spark plugs and you’re not doing your car any favors

mikerosi, how did you do it? Obviously you have to take off the rear bumper which I have done. No big problem. Did you have to remove anything else like the rear fender liner or intercooler duct work?
