Rear seat noise (rattling, clicking and squeaking) in Volkswagen Golf

A common source of noise (rattling, clicking and squeaking) is the rear seat latches, when the seats move the lock mechanism moves around on the latch and makes a noise. You could try tapping them with a hammer from above to bend the latch slightly downwards but this doesn’t seem to fix the problem in most cases.

To test to see if it is the latches making the noise drive around with the seats lowered. If it is the latches the simplest fix is to wrap some electrical tape around the latch where the lock contacts it to stop the movement and remove the metal on metal noises. The fix should last for around 50 operations of the rear seats before you have to reapply the tape and only takes a few minutes and a roll of electrical tape (3M Temflex 1610 was used but any quality brand is ok, avoid cheap brands) in any colour except for body colour or black as you won’t be able to see if parts of the tape are stuck in the mechanism or if the tape requires replacing.

  1. Lower the rear seats
  2. Clean the latch with a suitable cleaner (99.7% Isopropyl alcohol or similar is suitable)
  3. Wrap 14cms of 3M Temflex 1610 electrical tape (or equivalent) which will give you six full wraps.
  4. Close the rear seat

(this is the tape after many uses, it should be replaced before it looks like this – I had started to peel it back prior to the photos)

DuPont Krytox lubricant – door seals, hinges, latches, squeaks and rattles

DuPont Krytox is an inert lubricant designed originally as an aerospace lubricant suitable for many areas around the car including door seals, hinges and latches. The product can also be used between plastics to prevent squeaks (see list below of some applications). Unlike petroleum based products (silicon and lithium grease t0 name two common products) Krytox will not damage rubber products. Before applying to rubber surfaces they should be free of all contaniments and the use of a IMS (Industrial Marine Solvent) similar to 3M General Purpose Adhesive Cleaner and Wax Remover (part number 08984) is recommended.

Krytox comes in two package types from DuPont, an oil and a grease. Volkswagen sell both plus an aerosol, most auto manufacturers sell Krytox repackaged.

Oil – used on Eos to protected the weatherstrip – best for seals –

  • Description: Weatherstrip lubricant – 30ml
  • Part number: G 052 172 A1 (G052172A1)
  • Price: AUD$120 / USD$60 (edit price AUD$53.95 from Australian Dealer – 8/7/2010)
    • DuPont part number: GPL 105
    • GM part number: 3634770 (around USD$25/29ml)

Aerosol – majority of the can is propellant so only useful for areas you can’t reach or get the product into with an applicator

  • Description: Aerosol – 100ml (5-7% Krytox)
  • Part number: G 052 172 A2 (G052172A2)
  • Price: USD$70

Grease

  • Description: ?
  • Part number: G 060 172 A3 (G060172A3)
  • Price: ?
    • DuPont part number: GPL 205 (around USD$40/56.7grams)

What is Krytox?

Krytox is a high-performance, non-flammable and chemically inert lubricant that is compatible with oxygen and has a strong resistance to aggressive chemicals. Krytox® provides extended life across a wide range of high-temperature applications.

Krytox oil is a perfluorinated polyether. It is a liquid fluoropolymer, similar to liquid Teflon®. Greases are made with various viscosity grades of PFPE oil that are thickened with special PTFE grease thickeners to match the performance capabilities of the oils. Various additives for corrosion protection, extreme pressure conditions, or antiwear improvement are added to some of the grades.

Krytox is compatible with all seal materials. It is chemically inert.

Krytox is a very safe lubricant to use. All Krytox products are chemically inert. Krytox oils are even used in cosmetics and the greases as barrier creams. The materials decompose at temperatures above 343°C (650°F); some of the decomposition products are potentially hazardous.
Krytox does not contain any Volatile Organic Compounds. Krytox® is made of fluorine, oxygen, and carbon. It does not contain any hydrogen.

  • Extends life of seals.
  • Our lubricants can be used as barrier fluids or sealants.
  • Completely non-reactive.
  • Broad elastomeric compatibility.
  • Won’t react with acids, bases or other harsh chemicals.
  • Chemically, biologically and environmentally inert and silicone-free.
  • Contain no VOC materials or chlorine and are not hazardous to the atmosphere or ozone layer.
  • Undamaged by and non-reactive with acidic or caustic cleaners and disinfectants, steam, moisture and high temperatures.

Applications

Knocking noise from retaining band on luggage compartment cover

The luggage compartment cover has two retaining bands to hold this up when the rear hatch is lifted.

Under certain driving conditions the balls swing and knock against the plastic on the rear hatch.

This fix covers the two types of rear parcel shelf and costs under AUD$10 requiring only one simple parts that are required from any office supply store or from ebay (under AUD$10 for 2-5 delivered).
