Mk5 Golf R32 Test drive

Doesn’t feel like a Mk5 Golf R32 should. Lack of power while driving. Something doesn’t feel right. Noticed check engine light on dash upon entering vehicle. Needs a CEL diagnostic.

Mk5 Golf R32 Inspection

• Check engine light is on – Needs diagnostic.
• Oil is pitch black. Smells like fuel. Needs an engine flush and correct oil for engine.
• No service history record on CarFax of any transmission service. There are known problems when changing transmission fluid at high milage w/ no history of previous transmission service.
• Contact customer to let them know this before proceeding with service.
• Engine air filter needs replaced
• HVAC Cabin filter needs replaced.
• Front suspension needs most of the bushings replaced.
• Needs an alignment due to worn suspension bushings.
• Coolant freeze / boiling point too low – diluted. Needs flushed.
• A/C needs serviced. Not blowing that cold.
• Front brake pads look like they were replaced, however the rotors are below minimum thickness requirements. Looks like they turned the rotors.
• Rear brakes at ±4-5mm and need replaced.

Mk5 Golf R32 Scan Test

• P0322 Ign. /Distributor Eng. Speed Inp. Circ: No Signal & No Signal/Communication
• P0171 & P0174 Fuel Trim, Bank1:System Too Lean Upper Limit Exceeded
• P1114 Bank 1, Sensor 2:Internal Resistance Too High Implausible Signal

Oxygen Sensors Diagnostic

Tested o2 sensors connectors. Grounds tested – Passed. Power to Connector – Passed. Ohm readings 0.5-0.8 – Passed. Needs new Oxygen Sensors.

Crank Position Sensors

Tested CPS connectors. Sensors harness meets workshop manual specs. Grounds tested – Passed. Power to Connectors – Passed. Ohm readings – Passed. Needs new CPS.

While installing the oxygen sensors, we found that the EGR bracket is broken and is loose on the back side of the engine. Need to secure the EGR so it does not damage anything else.

After removing the intake manifold we found the valve cover is leaking on the back side of the valve cover and  inside the spark plug tubes. Ignition coils are in very poor condition due to long term oil leaking. Highly suggest replacing the spark plugs, coil packs and PCV, while we have the valve cover off.

Mk5 Golf R32 Valves look almost brand new. Zero carbon build up. Tested compression while the spark plugs were out. Compression is very good considering the engine having 144k on it.
