Life span of mechanical parts on Pug 406

As far as I know I have always done the following to make sure a car lasts a long time.

Change oil very regularly 5000-10000 miles. Change Fuel filter fairly regularly (important on a diesel) + Drain Water of course... Get long life air filter, such as K&N or renew paper element regularly. Don't rant engine whilst cold. Let engine idle before turning off to prolong life of turbo. Clean and wax twice a year with a good product. Use a quality wax based sealer on the exposed bits underneath the car. Stay away from mechanics, do what you can yourself. - Controversial I know, but....

I'm sure this list is endless, but this is what I do.

not bad but i dont recommend a performance air filter with a hdi engine also use good quality fuel i.e not supermarket shit

As far as I know, supermarket fuel comes from the same distribution depots as any other fuel, there are distribution depots around the country where you can watch all of the various supermarkets and oil companies lorries coming in and filling up, they mostly use the same shit, just different prices.

If you say you would not recommend using a performance air filter, then please state why, my thinking was that they improve air flow, allow the engine to breath easier and filter air to a higher degree than paper filters, this has to be a good thing for most engines.

As far as I am aware manufacturers only use paper filters because they are a lot cheaper to make than anything else.

A good air filter is even more important in a diesel than a petrol surely, as a diesel's power output is purely reliant on how much air it can get into the combustion chamber with the given amount of fuel. There is no throttle in a diesel, so it always puts the same measure of diesel in that your right foot requires.

Can I add two pennywoth. Aside from normal servicing etc. I have found one item that proved expensive and, seeing many posts since, seems to be a common problem with HDI cars. The fuel lift pump in the tank starts to break up and contaminates the entire fuel system with metal particles. Peugeot repair this by replacing everything from tank to injectors at a price of about £3,500. Mine was caught early enough that the particles had not got through the filter (if left they will) a non Pug mechanic was able to replace the pump and filters and flush everything through (even that cost £800, £500 of which was for the pump). That was a year ago and the car has been fine ever since. My tip then, is to regularly check the filter - I believe it is under the back seat - and act at the first sign of contamination by metal particles.

Hi,

Yeah, I know a guy which had a problem on a 307 90HP, perhaps a couple of months ago. His 307 is from the early ones built, of course not covered by warranty anymore, and Pug took all the charges.
