CoolBlueGlow describes a right-rear plunger-sensor repair on a 2005 R230, with Xentry diagnosis, careful board work and a conditional position check.

An owner’s fuse checks, immediate hydraulic-fluid loss and later hardtop correction, alongside a supplier’s cylinder-location diagram.

NCBlue’s engine-out project expanded to camshaft pinning. Later reports describe a chain-position incident, head removal and an unresolved base-gasket separation, showing why the early planning needs its follow-up.

john_s reported an immediate bank-one misfire on his 2008 E92 M3. A zero-compression result on cylinder 1 led to a broken valve spring; he later reported good compression and a return to daily driving after replacing it.

RicardoD’s well-running but increasingly oily 1990 Carrera 4 led to an engine-out reseal, cylinder-head work and a long reassembly project. His choices and setbacks are documented through assembly, without establishing a post-rebuild road-test result.

spawnywhippet documented replacing an ABC tandem pump after intermittent red warnings and repeated loss of prime. His account covers restricted access, fluid cleanliness and banjo-connection pitfalls; later replies clarify the limits of his fastener settings.

USMC_DS1 replaced the water pump preventively on his 2008 C2S at over 52,000 miles. His account centers on tight access, a separate thermostat-housing gasket and careful reassembly; later replies add different owners’ pump-condition and access reports.

studio112 first suspected the oil-cooler seals, then reported that the original leak came from the power-steering pump. Two replacement coolers reportedly leaked at the mounting face; reinstalling the original cooler with new O-rings ended the cooler leak.

r6cavy traced small drips appearing as the engine cooled. A borescope and cleaning drew attention to a cover bolt, but the owner still reported weeping after slightly tightening it.

epj993 opened the bonded glass lenses, cleaned and repainted the housings, then resealed and realigned his fog lights. His account includes the destructive flange-removal step, a repaint after trial fitting, and a later report of almost two years without fading or chipping.

F/51 LRS investigates a 964 whose converted R134a air conditioning will not cool properly. Relay checks, gauge readings and leak searches lead to component replacement, but the cold-air result remains unresolved; replies clarify the control signal and wiring differences.

dkraige replaces a cracked filling hose and a brittle coolant connector in one cooling-system opening. His account preserves the difficult reservoir connection, broken plastic removal and the clamp-clearance concerns that remain after installation.

PV997’s repair research separates the 997.2 PDK valve body and sensor access from the control unit inside the car. It brings together his investigation, later contributors’ experience and the fluid-fill and calibration work discussed in the source.

One W463 owner describes a persistent right pull that remained after extensive suspension work and two steering changes, then reports straight tracking after fitting a gas-pressurized Bilstein steering damper with custom mounts. The author calls it a band-aid; the underlying cause remains unresolved.

theanalyst’s 2007 Tiptronic 997 Turbo engine-out repair progressed through used replacement turbos and plumbing, a second removal after a leak test, shaft refitting, and a first start with a short drive. Cooling checks and an intermittent idle hunt remained unresolved in these updates.

NikleinR6 traced intermittent trunk closing assist to leaks around the latch housing’s ball-bearing plugs. His repair and later owners’ follow-ups show both restored operation and recurring faults.

bobomoto1 found a loose front wiper motor after the wipers stopped in heavy rain. He later reported a cracked motor and had it replaced; another owner described a failed substitute-motor fit and a separate welding repair.

White Spyder traced a roof hydraulic leak to the front locking cylinder, replaced its sealing ring and reported three leak-free roof cycles. Later owners describe seal durability, rebuilt cylinders and a reassembly alignment problem.
