2022 MORGAN PLUS SIX

Typical onset: 15,000-40,000 mi

Symptoms: Red transmission fluid pooling under vehicle near front subframe, Transmission temperature warning on dash during spirited driving, Low fluid level detected during service

Fix: The routing of ZF transmission cooler lines through Morgan's custom chassis can create vibration stress points where lines meet fittings. Requires dropping the front subframe cross-member for access. 4-5 hours labor including fluid refill and system bleed.

Estimated cost: $900-1,400

Symptoms: Condensation visible inside headlight lens after rain or car wash, Intermittent headlight failure warning, Flickering low-beam operation, Corrosion on LED driver board connector terminals

Fix: Morgan's traditional styling means less-than-ideal headlight sealing against water ingress. The custom LED modules are adapted BMW units but with modified housings. Replacement requires new sealed assembly—repair attempts rarely hold. 2 hours per side for R&R and IBUS coding.

Estimated cost: $1,200-1,800 per headlight assembly

Typical onset: 20,000-50,000 mi

Symptoms: Harsh clunk when shifting from Park to Drive or Reverse, Excessive driveline vibration at idle in gear, Visible tearing or separation of rubber mount elements, Metallic banging during hard acceleration

Fix: The BMW B58/ZF combination wasn't originally engineered for Morgan's traditional ladder-frame chassis with its different mounting geometry. This creates unusual load angles on the transmission mount. OEM BMW mount doesn't last—aftermarket upgraded bushings recommended. 3-4 hours with subframe support required.

Estimated cost: $600-1,100

Symptoms: Random electrical faults—fuel pump, cooling fans, or instrument cluster dropout, No-start condition after heavy rain or wet weather, Check engine light with multiple system fault codes stored, Green corrosion visible on fuse terminals and box connector pins

Fix: Morgan's cowl and scuttle drainage isn't perfect—water can wick into the engine bay fuse box despite the cover. This is especially problematic in the Plus Six because it uses BMW's complex IBUS electrical architecture that doesn't tolerate corrosion. Requires fuse box replacement, pin cleaning/replacement on affected harnesses, and improved drainage routing. 6-8 hours for proper repair including harness work.

Estimated cost: $1,800-3,200

Typical onset: 30,000-60,000 mi

Symptoms: Oil smell in cabin with top down at operating temperature, Light oil misting visible on valve cover perimeter, Small oil level drops between services (not severe consumption), Oil residue on exhaust manifold heat shield

Fix: The B58 valve cover gasket is a known BMW wear item, but Morgan's tight engine bay makes access more difficult than in a standard BMW application. Gasket and updated grommets for ignition coil penetrations needed. 4-5 hours due to Morgan-specific clearance issues around side panels.

Estimated cost: $800-1,200

Typical onset: 10,000-30,000 mi

Symptoms: Hesitation or stumble under hard acceleration, Limp mode activation during sustained high-load driving, Fuel pressure fault codes stored, Engine cutting out intermittently then recovering

Fix: Some early Plus Six units had manufacturing debris left in the hand-fabricated aluminum fuel tank. Particles migrate to the high-pressure fuel filter and choke flow. Requires both filter replacement AND tank drop/cleaning to prevent recurrence. BMW high-pressure fuel system is very intolerant of contamination. 8-10 hours for complete remediation.

Estimated cost: $1,500-2,400
