Power Steering - Pump appeared to struggle - replaced belts and used a lighter/thinner power steering fluid, which cleared this problem up.
Relay problem with Electronic Control Unit (Air con and temp display) - found faulty relays were to blame (located under the steering wheel area). Try replacing these before giving up (may be in different place, depending on country).
Radiator Pressure Chamber sprung a leak, easily fixed - new part.
Brilliant Cruise Control, Supple Seats (leather treatment helps these soften up GREATLY). All good gadgets and everything one could want. Suspension could be a little softer on the normal setting, but otherwise, love the sound of the engine / exhaust note, and gets a lot of looks in Australia, as we only sold 48 of these. (Spoiler helps this)
607 Mags look great and freshen up the appearance.
Brilliant, soporifique-I just bought my first 605,complementing my lovely 604 and daily drive 505 SRDt.
The only car that feels like the 605 is the Bentley Brooklands 1990s..Peugeot marketing in Australia has been run by dimwits... what a shame they did a worse job than was done with the 604.I met one of the marketing guys from Peugeot Aus.-Sime Darby, I told him what a disapointing job they were doing with the 607.All they want to sell seems to be 307s.What a shame.
