This also came on the Polo Mk3. The Lupo 1.7 SDI is also effectively the same engine with a slightly reduced stroke to lower displacement. Older VW Caddy had them as well. Used by VW as a marine & industrial engine too. Love it :D
I never had an SDI but those engines are work horse that takes you absolutely anywhere with incredible MPG and can’t go wrong with them! They are extremely reliable and bulletproof! No turbo or intercooler go wrong!😊
love my little lupo SDI. Ive had 15 odd cars to date but my little lupo has been the most reliable and cheapest to run. 60mpg around town, £35 tax and this year was my cheapest insurance ive ever had just £77 full comp
If you have the Bosch fuel pumps, you can run them on Veg Oil. I've been running 80/20 Diesel to veg oil for about 10 years on my SDI. 240k miles, serviced yearly and consistently goes over 10,000 miles a year. Will last for however long someone would want to drive car for (and that's rarely too long given the power!)
#LoganCarter how is it in winter? Do you still go with the mix or just diesel? Can it run with any type of vegetable oil? Used cooking oil or used engine oil? Tks
@Dat Boii Mate modern diesels have EGR valve that deals with soot, DPF gets hot like a cat and removes other pollutants. Diesels have a DPF benzin cars have a cat.
Paid £480 for an sdi golf estate mk4 6 months ago, flew through an mot no issues sat on 220000 miles and feels like it could do that again, sure the lack of power is boring but around town you can't raz around too much anyway, with the price of diesel at the moment the economy is too good to care about speed! Also can be run on veg oil if diesel gets too much more expensive! Great engine would recommend anyone try it for a cheap reliable car
I had two VWs with the same SDi engine. One was a Mk3 Golf for 4 years (M reg), then when the body was too tired, I scraped it and bought a X reg Polo Estate, same SDi unit. Bullet proof, not a care in the world with BAGS of torque. I could set off in 2nd gear without touching the accelerator at all. Amazing engines.
Im from the Netherlands, have a golf with the 1.9 SDI AQM engine absolutely bulletproof engine. Just give them the service they need and on the road u are! Im having 478.000 Kms now on it now haha, lets hope i can make it hit the million🤭🤣
"SaugDiesel Direct Injection" - that means it is Diret injection was an improvement over the whirl chamber 1,9D NA diesels, without a turbocharger. In theory they are very simplistic, but in some cases they are paired with really badly designed gearboxes, especially the 2.0 sdis in caddys. The DI gave it an improvement over the whirl chamber engines in terms of fuel economy. Ok, all diesels are "pressurized" otherwise the whole principle wouldn't work. The PD stands for Pumpe-Düse, which is a kind of unit injector engineering idea where the actual injector makes the injector pressure without a high pressure pump like your SDI has. The actual injection pressure is about 10 times higher on the PD though.
They should make it law that ALL cars use this engine, very economical, no road rage speeding away to beat others from lights, if you want a nice looking car just make the body look good, everyone would be equal in the world regards speed , you just have a nice looking body on your car to show you got a bit more money, if everyone doing a similar speed you can appreciate the prettier cars around you 👍
Just loved ur review! I have here is Spain a skoda fabia 1.9 sdi like that one...at the moment 325.000 kms and just the normal maintainance, i am in the mood to try to hit the half a million kms with this one. Do u think it is possible? Cheers
I have the same engine on my Polo 9n and I should add 1/2 litre oil every 1000 km! , do your car have oil consumption? And what kind of oil engine oil you are using?
I had a VW Golf MK4 1.9 SDI and the engine never used oil at all even at 257000 miles when I sold it. It did have a slight leak around the valve cover gasket it probably leaked 0.25 litres of oil every 1000 miles
I'm looking into buying a 2003-04 VW Polo with the 1.9 SDI and i was wondering if it's a good choice? I have read that it's very reliable and firm, but what about maintenance? Is it expensive to maintain? Thank you to anybody who will reply.
Having a 1.4 tdi mapped to 105hp polo i think it's also a great engine despite being a wobbly 3 cylinder that people say cause a lot of trouble. It's been in the family and serviced at home for over 10 years and it never gave any bother. It also does 70mpg easily!
Pd does not stand for pressurized disel pd is pumpe duse german for individual fuel pump for every cylinder so 4 cylinders 4 mini fuel pumps vs common rail one bosch pump and 4 injectors
I live in America and I have a 2003 VW jetta tdi with basically the same engine just turbocharged and it has 442k miles on it lol I could not imagine it spit out the turbo because this car is already slower than dog shit as it is lol
