Is an HDI engine and DCI engine the same?

The PD injector setup is driven directly from the (one and only - it's an 8 valve motor) camshaft. This puts huge stress on the belt itself. I have heard of VW dealers charging upwards of £800 for a belt and tensioner change. Ouch!!

PSA's engines use the belt to drive the high pressure pump but it's a constant load device. VW's PDs are not common rail engines and therefore the loading on the belt is constantly changing with every 90% rotation of the camshaft.

The 2.2 HDi is very different to the 2.0 HDi. The refinement is in a different league, as is the power delivery. VAG's 4 cylinder PD diesels are crude and noisy in comparison to either of the aforementioned PSA units.

The belt only drives the intake camshaft in the 2.2 HDi (it's a twin cam 16 valve motor) - there is an internal chain within the cylinder head to drive the exhaust camshaft and this is maintenance free.

I've been telling people for years that VAG cars are over rated, yes they can be very reliable but when things do go wrong (and they will because no car is perfect) then they can cost thousands to fix, I mean they will change over £800 for a routeen maintainance item so who knows what they will charge when your air con compressor or power steering pump goes down the swany......

I'd probably say the best car maker at the moment for price, reliablity and inovative products and I have to say my family have never been a fan of these guys but they have made some rather good stuff lately, and that's Ford....

Really? well have you been in a new Mondeo? It's well built, it rides really well, it's comfortable, well priced, it has a big selection of engines and trims and the like and it drives rather well,

Paul, I've driven my Grandads Mondeo 2.0 TDCI auto and I tell you know you would like it, it may not be quite powerful enough for you but the gearbox is one of the best in the business and the engine is silky smooth and big enough to cart around the family and best of all you can have the newer 2.2 172 hp twin turbo diesel with the very same gearbox....

I tell you know if I was in the market for such a thing they would be my first port of call....
