I read (in the motoring section of one of the Sunday papers) that the Citroen/Peugeot 2.0HDi has a turbo.
If this is the case,
1) why don't you get the audible 'whistle' that the VW/Audi TDi gives on acceleration?
and,
2) does that mean they're not such a good buy 2nd hand (with all the warnings about older smoking turbos?
and finally,
3) if they are still a good buy what mileage (with a serviced example)should you start to be wary?

Dont worry about turbos. You will find it very hard to find a decent modern diesel without a turbo. MOst turbos dont whistle.

Its due to wastegate valves, though I've never heard a whistle on any diesel turbo.
2) does that mean they're not such a good buy 2nd hand (with all the warnings about older smoking turbos?
The lower pressure the turbo is run at, the less stress it is experiencing.
3) if they are still a good buy what mileage (with a serviced example)should you start to be wary?
The only diesel turbo I've ever seen fail was on a Citreon ZX TD, but this only failed cos I drove it at high speed, 46 yards through a foot long puddle. Unfortunately the puddle was 50 yards long and hydrauliced the engine, seized the turbo, wrecked the alternator, brakes and didn't do much for the rest of the car!
Most diesel turbos are run gently, though its important to simmer them when they've been driven hard before turning the engine off. This isn't really milage or servicing related, I'm sure I could kill a turbo by doing this a couple of hundred times, so possible in less then a 1000 miles if I tried. Just make sure that the turbo kicks in when it should and you won't go far wrong.

Some diesel engines are available in different power outputs achieved through different levels of turbo boost. Presumably the higher output versions whistle more than the lower ones. Today I saw a Peugeot 406 that was whistling quite healthily!

Can you even get (new) diesel cars without turbos? The kick from the turbo on my Xsara is sufficient to spin the wheels on a wet road as it passes through 3000RPM.
PS. It whistles whenever the car is on boost but not accelerating - ie, when cruising at motorway speeds. Assured by garage it's nothing to worry about.

Skoda did a non turbo Octavia, an SDI as opposed to a TDI. 68bhp rather than 90 or 110. VW offered a non turbo Golf too.

you can get new VW caddy vans in non turbo (SDI) and Turbo (TDI) but very few passenger diesel cars come without Turbos.
|
Citreon Berlingo is still available as a 1.9 non turbo diesel, guess thats mainly due to the van version though.
Skoda fabia also still available as a 1.9 Sdi 64bhp version and the VW Lupo 1.7 Sdi as well

Turbos on diesel cars run much cooler than their petrol counterparts due to the diesel engine being more efficient. I'd only be concerned about turbos on thrashed petrol engines rather than a diesel. If you buy any turbocharged car though, ensure oil changes are done as per manufacturer's requirements as usually the engine oil lubricates the turbo's bearings. Once you have a decent turbo diesel you'll never go back!

I never know why people worry about turbos. I've driven (2nd hand high-ish mileage) turbo powered cars for the last 8 years (c. 160k miles) and only had to replace one turbo which cost less than a set of tyres all round.
