Summary of repairs from 11 March to 7 May:
All costs were covered under warranty, inclusive of VAT, with internal discount stated (where relevant).
Recap of issue: The car exhibited a slight vibration at higher revs and high speed. The car was booked it at a Porsche Centre workshop on 11 March. The car was purchased as an Approved Preowned car from Porsche in January.
Work item 1: The wheels were road force balanced. No impact on issue. No cost.
Work item 2: Both rear side drive shafts were removed and reconditioned. According to the report, they were not machined, but were regreased and had rubber boots refitted. No impact on issue. Cost = R3,500.
Work item 3: After failing with the above, a claim was made to replace the PDK transmission. A reconditioned transmission/gearbox was ordered from Germany and finally landed in SA on 28 April (remember the car was booked in on the 11 March). Reconditioned/refurbished parts are called "Porsche Genuine Exchange parts" and are backed by the same warranty as new parts. Cost = R107,633 (that is after 25.5% internal discount)
Work item 4: While my car was spending time at the workshop waiting for the gearbox, I asked that the warped interior door panels (common fault on 981 cars) be fixed. A warranty claim was made and new panels were fitted. This was not a simple job, since the entire interior door rubber/leather panel had to be replaced. Cost = R27,140 x 2 for both doors! (that is after 25.5% internal discount).
After fitting the gearbox, it took them 4-5 days of occasional test driving and tweaking the settings to get the PDK properly calibrated.
Work item 5: Wheel alignment prior to delivery. No cost.
All-in-all, after internal discounts and labour, the total invoice came to R158,460 and was covered by the warranty (part of the preowned maintenance agreement).
Funnily, when I arrived at the dealership on 8 May to collect the car after 2 months, I was handed another invoice for R500. This was for my cost, since it was for petrol that they had to fill in the car. Seeing that the service manager was not there (it was a Saturday) and I was not in the mood to raise a fuss with the accounts person, I paid it and they released the car. A free car wash was done before delivery on the day.
What did I learn about buying a used Porsche?
a. Never buy a used garage queen (i.e. ultra low mileage) Porsche that is more than 5 years old. Searching online forums, reveals that older Porsches driven with decent annual mileage (being 10,000-20,000km pa at least) by the 1st owner usually have fewer issues after the original maintenance plan expires. This is also due to the fact that issues that come up with increasing mileage are picked up while the car is still under 5 years of age and under Plan.
b. Always stress test (drive and brake hard) a car before buying it. I bought this car without test driving it at high speed (the vibration issue was most noticeable above 120kph, in low gears).
c. Never buy a Porsche as your only car, especially as your only family car. The long wait on parts is not uncommon. While you do get a courtesy car, these are not in the best of condition (disclaimer - this is based on my experience at the Pretoria dealer. Not sure if JHB has same policy). I had 2 Cayennes as courtesy cars in that 2 months of waiting. Both had over 100,000km and the one was pretty banged up (window switch broken, overspray on body panel, leather tearing), while the other had an oil service due and worn rear tyres (I had to ask the dealer to sort this out). I would not take a long family trip in those courtesy cars.
d. Prepare to wait a long time and be aware of the complicated flow of Porsche communication from SA to Germany. All comms get routed through the Abu Dhabu office (SA falls under Middle East and Africa region) and they are closed on Fridays.
e. Pay up for the annual preowned maintenance agreement (Plan) extension. It is R36k pa and you can extend until 12 years or 150,000km total from the date of initial registration of the car. You get 1 year free, when buying a used car older than 2016 from Porsche. Newer used cars get 2 years free Plan.
f. Do not expect brand new parts to be fitted. The Plan says that Porsche have the right to fit reconditioned parts. But, these still carry the same warranty as new parts. Frustratingly, these parts do not arrive any quicker than new parts from Germany.
In another post, I will give feedback on how the car drives after the repairs.
