Known weak points

Curated by Redline from owner club and specialist sources Commonly reported by owners and specialists for the Volkswagen Golf GTI Mk5 (2004 to 2009). Not every car has these; check this one.

  1. High pressure fuel pump cam follower

    The cam follower that drives the high pressure fuel pump can wear early, especially on long life serviced cars, and failure can cause serious top end damage.

    Where to look
    The cam follower under the high pressure fuel pump on top of the engine
    How to test
    Ask whether the follower has been inspected or replaced. Specialists replace it about every 20,000 miles.
    Cost if it needs fixing
    High cost a cheap part, or top end damage if it fails

  2. DSG mechatronic unit

    A lurch when pulling away from a standstill points to a failing DSG mechatronic unit.

    Where to look
    The DSG gearbox
    How to test
    Pull away gently from rest several times and feel for a lurch.
    Cost if it needs fixing
    High cost a new unit costs about 900 pounds plus fitting; rebuilt units are cheaper

  3. Cambelt

    The cambelt, water pump and tensioners need replacing on schedule.

    Where to look
    The cambelt cover and the service records
    How to test
    Look for an invoice for the last belt change.
    Cost if it needs fixing
    High cost belt failure damages the engine

    Sources: pistonheads.com (opens in a new tab)

  4. Diverter valve

    The rubber diaphragm in the diverter valve wears and lets boost escape, giving a flat spot and lost power.

    Where to look
    The diverter valve on the turbo
    How to test
    Feel for the boost kick at about 2000 rpm. Sluggish pull points to the valve.
    Cost if it needs fixing
    Low cost an upgraded valve is cheap

  5. Coil packs

    Coil packs are a regular failure point.

    Where to look
    The coil packs on top of the engine
    How to test
    Feel for a misfire under load and check for an engine warning light.
    Cost if it needs fixing
    Low cost a set is about 80 pounds in the UK

    Sources: pistonheads.com (opens in a new tab)

  6. Oil use and valve carbon

    Carbon builds up on the back of the inlet valves and oil use can rise. VW considers a litre every 1,000 miles normal.

    Where to look
    The dipstick and the inlet valves
    How to test
    Check the oil level and ask how much it uses between services.
    Cost if it needs fixing
    Medium cost inlet valve cleaning

    Sources: carmagazine.co.uk (opens in a new tab), pistonheads.com (opens in a new tab)

  7. Crankcase breather valve

    A failing breather valve gives a poor idle and an air leak sound when the engine is switched off.

    Where to look
    The crankcase breather valve on the engine
    How to test
    Listen for a hiss right after switching off and watch for a hunting idle.
    Cost if it needs fixing
    Low cost a cheap valve

    Sources: carmagazine.co.uk (opens in a new tab), pistonheads.com (opens in a new tab)

  8. Rear dampers and tyre wear

    Weak rear dampers wear the inner edges of the rear tyres and can cause a drone like a worn wheel bearing.

    Where to look
    The inner edges of the rear tyres and the rear dampers
    How to test
    Run a hand along the inner edge of each rear tyre and listen for a drone at speed.
    Cost if it needs fixing
    Medium cost dampers and tyres
