Options that matter

The factory options most often fitted to the cars we track and what they cost new. What each option does to the sold price is on 911 Tracker with a free account. Check every option on the VIN with the VIN decoder before you pay for it.

What to look for

• Connecting-rod bolt engine fire recall (14V090)

  Early MY2014 cars: a loosened connecting-rod bolt damaged the crankcase, causing at least two engine fires. Porsche replaced the engine in all 785 cars built to that point.

  What fixes it: Recall AE01: new engine with optimized rod bolts plus software updates; affected owners got an extra 12-month warranty. Check that the recall was completed (VIN-specific).

• Finger-follower (valve lever) / camshaft wear

  A metallurgical defect in some batches of finger followers caused wear, leading to high-rpm misfires (P0300-P0306), check-engine light and limp mode, mostly around 7,000 rpm on full load. Affects 2014-2016 GT3 (not the 991.1 RS or 911 R).

  What fixes it: Porsche revised the finger followers and camshafts; the TSB remedy is replacing all camshafts and valve levers, and Porsche added a transferable 10-year/120,000-mile engine warranty for this fault (engine replacement if it fails).

• PDK clutch-fluid service

  The GT3's PDK needs a periodic clutch-fluid change (Porsche schedule shown as 48k miles / 4-6 years; specialists suggest ~30k, and more often for regularly tracked cars). Skipped service is a common gap in records.

  What fixes it: Perform PDK clutch-fluid (and later transmission oil) service per schedule.

• Carbon-ceramic (PCCB) rotor replacement cost

  PCCB was optional; discs are replaced for chips/cracks or wear and are roughly 10x the cost of iron rotors. Mainly a concern on tracked cars.

  What fixes it: Inspect discs and pads before purchase; replace or convert to iron rotors.

• 991.1 GT3 engines

  Early cars were recalled and many had engines replaced by Porsche. Check what was done and that the paperwork is with the car.

• Over-revs

  Manual cars store over-rev history in the engine computer. Read it with a factory scan.

• Front lift and PDCC

  Check every hydraulic option works; they are costly to fix.

Intervals are whichever comes first, miles or years. "Porsche factory (converted from km)" means Porsche's own figure for another market, turned into miles with the same km-to-mile pairing Porsche uses in the US.
