VW passat, 1.9 and 2.0 tdi engines, difference?

construct06

What is the difference between the 1.9 and 2.0 tdi engined vw passats from the 06 onwards range?

Obviously one costs more in tax than the other, but the 2.0 tdi engined cars seem to be a bit cheaper for some reason.

I have an octavia 1.9 tdi year 2000 and that engine is bullet proof.

There was a recall on some of the 2.0...injectors I think. Lots of problems with them but if they've been replaced, should be ok. Standard bhp in the 1.9 is 105 or 110, 2.0 is higher, maybe 140(?).

the 1.9pd(non bxe) are far more reliable than the 2.0tdi pd engine in the Passat. Oil pumps are the major issue on them with balancer shaft and hex drives wearing causing the pump to stop working thus starving the engine of oil which causes major damage.

early 2.0tdi pd engines also had a chain driven pump but like the hex drives these give issues and the sprockets can round off loosing their teeth. Later examples changed to a more robust gear setup but these cars still give balancer shaft and hex drive issues.

tbh Id save myself the heartache and get a 1.9

1.9 TDI PD is 105bhp, 2.0 TDI PD is 140bhp or 170bhp. 2.0 TDI PD is not as robust as the older 1.9 TDI. Certain versions of the 2.0 TDI PD engine suffer from oil pump balance shaft issues, they also suffer from injector problems but VAG issued a recall on these and were replacing the injectors free of charge. Both are not that refined and have a narrow power band.

I'd take a clean 1.9 TDI over a 2.0 TDI even if it cost a little more.

Technically, there are plenty of differences, depending on year.

As mentioned, the 1.9s of that era are all PD. They are a single camshaft, 8 valve engine, with intake and exhaust manifolds on the same side of the head. The basic design of the block and head dates back to the 80s: it's a total dinosaur.

The 2.0 engines were either PD or common rail depending on year: the CR engines came on stream in 2008 to replace the 2.0 PD which was really only a stopgap engine. All the 2.0 engines had a twin camshaft, 16 valve head with crossflow design (inlet and exhaust on opposite sides). Both had either 140 or 170 bhp options. They're much more refined and economical than the 1.9, but there are question marks over their reliability.

(Some) early 2.0 TDI engines (05-08) suffered from injector failures but these were recalled by VW about 2 years so should have been replaced.

The B6 Passat is a bigger/heavier car than its predecessor and the 2.0 is far better suited to it than the (even then) ancient 1.9 lump. I think the 1.9 is only 5 speed(??) whereas the 2.0 has 6 gears.

Best option (in my opinion, having previously owned a B6 for 5 years myself) is the DSG box mated to a 140/170bhp 2.0 TDI

There was a sport version of the 1.9 in a B5 Passat (2002 UK import), might have had a six speed box... But the torque and speed of the car was phenomenal, it was my daughters car and every time I drove it I couldn't get over how it would pin you to the back of the seat when you put your foot down and I was coming from a 1.8T 150bhp version of the same car. It had some poke for an "ancient" lump, more the the 520D that replaced it... felt like it anyway!

Sounds like it was remapped IMO. The 1.9 was never 'powerful' and would be even slower in a heavy lump like the Passat.

Edit: If it was remapped to 130-140 PS then the extra torque would make it feel pokey compared to a petrol but meh, it's still a big lump of a car and 130-140 in it is not fast.

Honest John said of the car I am talking about:

"TDI 130 S was an excellent car for company drivers because it combines a low CO2 output of 154 g/km with a low on the road price of £16,310. Has no less than 228 lb ft torque and goes like a steam train."

This sounds like the car I drove. Initially 1.9 in the B5 was available in 90 or 110 BHP, then they where upgraded to 100 or 130BHP, and perhaps this TDI 130 S version had different mapping.... and there was a 115 BHP in 2000 so a few different outputs from same engine.

The older 90 and 110 bhp engines used the VE injection system. The 115 bhp engine in the pre-facelift B5 was the first PD engine. The 100 and 130 bhp engines were PD.

The Sport and Highline B5s got a 6-speed gearbox with the 130 bhp engine which had closer spacing between the ratios than the 5-speed which would make it feel a bit quicker.

There was also a rare 2.0 PD offered in the B5 in the sport trim. It was 4motion only and had 136 bhp. The badging had TDI all in red.

I have the same car a 1.9 Tdi 130 bhp b5.5 2002 and there is serious power in the car

Serious power from a passat? Heheh

Well, if you're used to the wheezy little petrol engine that practically everyone bought back in the day, then the PD130 is going to feel quite fast.

Precisely. Torque is where its at no matter what any of them ever tell you

That's not what I said at all! My point was that if you're used to a 1.4 petrol engine with 75 bhp hauling around something like a Ford Focus, then 130 bhp is going to feel a lot faster no matter what the torque is.

Indeed. 130 bhp in a Passat most certainly does NOT make it a fast car, "diesel torque" (whatever that is) or not. The 1.9 TDI is well noted for feeling fast because all its power arrives in one big lump so once it gets onto the power band it makes serious progress compared to before it gets into its power band, but of course a massive surge in acceleration at one point in the power band is a totally different thing to real power and real acceleration. 130 bhp is not a lot of power, especially in something as big as a Passat no matter how much torque it has. A 130 bhp petrol Passat would be just as fast as the diesel if one knows how to use the gearbox correctly (holding onto the gears to get maximum acceleration when required as opposed to hopping into fifth at say 60 kph and then flooring it, which will get it nowhere), but would be considerably quieter and just more pleasant to use because of the superior refinement that is part and parcel of a petrol engine (especially in the case of the old PD engines which let everyone know you're driving a tractor engine because they're so noisy).

It is a very reliable engine as long as it's not the BXE model, but with a measly 105 bhp in the B6 model, is certainly not going to be fast. I've driven the B7 (which is just a facelifted B6) with the 1.6 TDI and that has an identical 105 bhp and that is dangerously slow, though it would have much taller gearing than the 1.9 so I expect the 1.9 TDI isn't quite so slow. Either way a Passat is a large car and really needs a 2.0 TDI or else one of the bigger petrols.

Problem with the 2.0 TDIs is their reliability if it's the one with the PD engine, if you can afford a 2.0 TDI CR I'd definitely go for that over the 1.9 as it's a much newer engine and has a lot more power. Even though the 1.9 is likely to be very slow I'd still go for it over a 2.0 TDI PD, those engines are just too much of a risk even with the injector recall for my taste.

Serious power for a 130bhp, I've driven faster cars but this Passat is seriously powerful for a 130 have a GTTdi golf at home sittin at 170 and there's little difference in them

170bhp Golf is much more powerful than a 130bhp Passat, and in power to weight terms the gap is wider again.

Well OP, some range of opinions so far !

Interesting that not one denies that its bullet proof

Also, no messing with DPFs & stuff.

What about fuel consumption ?

( I've read that it beats the more recent 1.9 & 2.0 VAG diesels handsdown.)

bazz26

And a plume of black smoke too that only a diesel can produce under heavy acceleration, no doubt... Bet it coos too.

When it comes to reliability and people's perception of it, it's worth remembering that you only tend to hear about the problems people have had, especially online. There's always a bit of bias towards the view that a car is unreliable.

The issues with the 2.0tdi PD are well documented though.

Moanin

I had a 2006 2.0TDI Passat for 6 years and loved it. It had the injectors replaced under the recall and steering column replaced . Other than that it was pretty reliable. It loved front wishbone bushes but I think all B6 Passat's do...

Xpro

Why is everybody slating BXE engine? In my experience from working with these cars I'm yet to see a problematic bxe engine other then a regular VW faults common across the range?

Can someone explain, other then asking google, throwing rods, etc and that type of stuff?

Thanks

Could the difference possibly be down at least in part to ridiculously wide tyres on the Golf compared to the recommended tyres on the Passat I'm thinking
