Hey guys, bought my 2016 GTS last year from the original owner, very well maintained, always been serviced at Porsche. I bought it at around 98k kms, it is now at 101. The major service is due at 54k or every 4 years. Checking the service history it shows the major was done in 2020 and plugs were replaced, but the pdk was not serviced. Is it common practice for Porsche to waive the 4 years on the pdk and wait for the mileage instead? I am currently driving a pdk that has never been serviced and it is starting to make me nervous...
