• Peugeot 406 (1996 - 1998) - 98 1.9 td white and back smoke 7 Dec 2008 (Forum)
  a brief history, cam belt went and all relevant work was apparently done, car was driven for over a thousand miles with no problems, 1st full tank of deisel about 2 months ago started to produce some white smoke under heavy acceleration and gradually as i worked my way through that tank of fuel it got worse, heavy acceleration produced a cloud of black smoke, upon reading many forums i took a look at the air filter and indeed it was clogged, nice easy job, new filter in and i still have the same problem, second full tank of diesel and and smoke is getting worse, 0-60 in 2 minutes to keep the smoke lvl down, car has full power and drives lovely as long as i dont look in the mirrors, i have also changed the fuel filter, it may be coincidental but the internal heater wires connection became black, crispy and intermitent, that has been fixed and is working fine, also i have noticed in the past week that the engine temp is not getting higher than 70 degrees even on a 80 mile trip, not sure why that is but i put some hardboard between the two rads to block airflow, with one eye on the temp guage and one hand on the internal fan switch i kept the temp around the 90 degree mark, but still the smoke, no matter what temp the guage sais i am getting lovely hot air in the car, also i have added diesel redex in these last two tanks of fuel, but everywhere i read sais redex is good, any good advise on how to resolve this and get my car back to not poluting everyone who is behind me will be gratefully recieved
• Peugeot 407 (2004 - ) - 2004 2.0 HDI 136 Fuel Economy 9 Oct 2008 (Forum)
  either way I think from owning diesels and talking to other diesel car owners that there is either something wrong or the economy on these Pugs is pathetic. Are there any things to go to the dealer armed with, any possible explanations?
• Volkswagen Touran MPV (2003 - ) - 04 1.9 Forecourt Diesel Pump Cuts out all the time 9 Sep 2008 (Forum)
  OK, I've been living with this for a while, but fortunately, the mileage is low on the Touran now, so it's an annoyance only once in a while. Whenever I fill up at any petrol station with Diesel, the pump cuts out at very low fill rate. i.e. I'm pulling the pump handle so gently that the flow of diesel means I can take 10 minutes filling the tank from empty to 50 Litres. If I squeeze any harder, it cuts out constantly, even at the low flow rate it still cuts out occasionally.
• Astra Diesel 22 Nov 2005 (Forum)
  Our W-Reg Diesel Astra Estate> has recently caused us some concern. There has been a sudden loss of power - hills which we used to fly up over in fifth gear now require us to change down through the gears. This is our second diesel Astra - the other we kept to 170,000 miles and never had this trouble with it. > We've changed the EGR valve.

• Volkswagen Bora - Brain teaser.. 52 plate Bora 1.9 TDI wont start 18 May 2014 (Forum)
  When the car is cranked over, all readings on my mates snap on diagnostic seem correct. We used a NOID to check the trigger signal to the injectors and all appear ok. When the fuel feed or return to the tandem pump is removed fuel sprays out therefore lift pump is working and filter not blocked. Fuel is clean diesel too. No engine oil in it or veg oil present. With the dreaded easi start hastily sprayed in to the inlet the engine will run but it is running on the easi start.
• Renault Kangoo - Double pre-heat 1 Jul 2004 (Forum)
  So far the responses from Renault have been "can't find anything wrong with it", "We have tightened the fuel pump and checked for leaks", and, once again, "we can't find anything wrong with it". On this occasion, they have found an entry in the error log relating to the problem (which was missing on all previous visits), and the diagnosis is a faulty fuel pump.
