2012 Porsche Panamera Engine 3.0 Diesel.
Tiptronic. Owner Simon E.

Brief: Fix sluggish Tiptronic gearbox

The objective was to service the gearbox and drop sump, and replace the filter and the ATF (Automatic Transmission Fluid). To our surprise, the Panamera had little oil left; it was running on only one-third of its capacity. Not good. We contacted the owner, mentioned we had a problem, and provided options to potentially save the box. The filler tube (Plastic) was damaged. A lot of black sludge, the 4 magnets were covered in it, a burnt smell. The box had been working hard! Chances were minimal due to driving with low ATF.

The final result was ordinary. Fortunately, Simon had another gearbox but wanted us to use certain additives to see if we could still save the original. Simon was fervently researching; we admired that. Liqui Molly had a product, but sadly, it was banned in Australia.

We expect the Panamera back once Simon’s additives are on hand. Watch this space!

1977 Porsche 911 2.7
Sportsmatic, Owner Ryan K. 65,500k

Brief: Back for further work e, e.g., repair burnt wiring issue. Bilstein Suspension, Sportsmatic gear linkage repairs, and rear sway bar fitment. The 911 is booked for a full bare metal respray on April 1st.

Work in progress: Wiring all repaired. Discovered several other issues, e.g., the ignition switch is intermittently at fault; Sportmatics have an electronic gear lever switch mechanism. There had been a previous repair some years back, a temporary repair. New part on order. Top & Bottom strut mounts require replacing; again, parts are on order.


At some point, either in Hong Kong or here, someone used the rear swaybar mount as a jacking point, destroying the mount. This requires complete fabrication. Ryan purchased a 25mm rear sway bar from the UK — an impressive bit of kit.

2009 Porsche Cayenne V6 Engine 3.6
Tiptronic. Owner Col. B.

Brief: Replace front discs, front pads, sensors and brake fluid flush.

2006 Porsche Cayman S Engine 3.8 (Kitted from 3.4 to 3.8)
6-Speed. Owner Carrisa B. 150,00km.

Brief: Full Engine Flush, Liqui Moly oil 5W40, Filter, LN Engineering sump plug/washer. Gearbox oil change and inspection of the Cayman.

The Cayman S is an extraordinary car; the early ones are small and compact and have aged beautifully. Carrisa drives Cayman’s as intended. Say no more!

We drove the Cayman in late February and noticed a gearbox whine. Annoying at best, we saw no printed record of the gearbox ever being changed. The oil was filthy—perhaps 20 years of use! After the gearbox oil change, the whine disappeared. The change was necessary. Keen eyes would have noticed the deepened sump. She now holds 9 litres. The Cayman has the IMS Solution (We consider the best)
