Peugeot 407 1.6 HDI endless boost issues. Here we are again, with an issue I've had with my 407 for nearly 18 months. It's been to countless garages and a diesel specialist having money thrown at it left right and centre with no real joy. Last week it was in a diesel specialist for 2 weeks and they said the turbo is duff and wanted near £900 My plan was to buy another newer 407 SW but now im not so sure. 407s 110 1.6 HDI retrofitted cruise+limiter A forum community dedicated for all Peugeot owners 407 1.6 HDi 16V DPF (KOX) (2009 – 2011) DV6TED4: 3.5 / 0.4: 20 000 km/ 24 months: 407 2.0 HDi 16V DPF (100 kW) (KOX) (2004 – 2009) DW10BTED4: 5.25 / 0.25: 30 000 km/ 24 months: 407 2.0 HDi 16V DPF (100 kW) (RHR) (2009 – 2011) DW10CTED4: 5 l Orange dipstick 5.5 l Yellow dipstick Filter 0.25: 30 000 km/ 24 months: 407 2.0 HDi 16V DPF (103 2006 PEUGEOT 407 2.0 HDi 136 X-Line 5dr Sw Estate Special Editions 2005 PEUGEOT 407 2.0 HDi 136 X-Line 5dr Tip Auto Sw Estate Special Peugeot : Black Peugeot 2006 407 SW (South Wales) MB Motor Group : PEUGEOT 407 1.6 HDi 110 S Diesel Panoramic Glass Roof 2005 Captain Pugwash said: We have had our 407 HDi Sedan for about 9 months (13500km). White Gold. This is easily the best car I've ever owned. Comfortable to drive or passenger in, excellent fuel economy ( average 7.2 L/100KM around town - 5.0 L/100KM highway) and no serious mechanical glitches. Long-legged drivers will find it particularly hard to adapt to the 407’s cockpit. Thankfully, the 407 ST’s 2.0 litre turbodiesel engine is an efficient unit that adds positively to the driving There are a few of things that can cause this, but there are many others. - Turbo Failure. - Diesel Particulate Filter issue (the 1.6 and 2.0 HDI versions usually have this during the pre facelift era) - Injector or injector pump issue. - Fuel filter blockage / fuel pump issue. I was wondering if any Peugeot 407 owners could give me a little advice for buying a used 1.6 407 estate and what to look out for? My budget is £1500 max and I am after the 1.6 diesel due to insurance quotes & mpg - I've got to do a couple of 2000 mile trips a year on top of the usual stuff. HAjL514.
