Hi All,

I am looking for some advice! I have recently moved house and I now have to commute a long way to work every day so I need to change to a diesel. As I have a limited budget whatever I get will have to last a loooooonngg time :-). I ideally was looking for an octavia but either price or mileage is way too high on any I have seen. My local garage has a 2004 reg 2.0tdi with 140000 miles and a 1.9tdi with 120000 miles, both for the same price. The dealer reckons that with the mileage I will be doing the 2.0 engine will be better as long as it is looked after but a friend reckons the 1.9 engine is far superior and more reliable... Help!

Meant to say its a Superb 1.9 or 2.0 tdi I am looking at incase anyone thinks I am posting in the wrong forum after referring to my preference for an Octavia

1.9tdi all the way as the 2.0 tdi has major problems (search oil pump) my 1.9tdi has just rolled over 210000 and run perfectly.

Don't even think about buying the 2.0. 1.9 TDI all the way...

My 1.9 is almost at 250K miles, without any problems encountered.

I'd like to know why the dealer reckons the 2.0 is a better option for you than the 1.9 - could the 1.9 be one of the lesser powered 115 or 100 bhp versions rather than 130?

In any event - avoid the 2.0

Probably because there is so much bad press about them these days that he's trying to shift it on desperately? Sorry I forgot, car dealers are all saints acting in the best interest of their customers...!

1.9 tdi 130 is the best, if your doing long runs, this is SWMBOs as you can see there is the potential to cover over 950 miles on a tank, the 620 on the left is how far you can go, and the 339 is how for its gone on a quater of a tank

Sounds like he needs to get rid of it :yes:

There are a few 1.9 tdi 130s on auto trader some with low mileages

Agree with all comments above - 1.9tdi all the way. What's your budget?

On the matter of the £6 steel pin that fails on the 2.0 TDI engine, a friend, who has had Audi TDI for many years 80 > A4 > A4 > A4, has now bought an A6 2.0 TDI. He tends to do highish mileage so after buying demos, tends to reduce them to low value mules after 6 years (120,000+miles). This A6, while approaching 100,000 miles, had the £6 pin fail, he stopped immediately, got Audi dealer to fix it, drove it for a day or so and took it back "crankshaft balnce out" - more money, as luck would have it, a few months later EGR problems so back in to Audi dealer "ah the cat is now died due to the EGR problem"! This car, over the past few months has cost him a serious lump of money. Audi and dealer just say its one of these things - ie not an issue, but he is now looking at M-Bs - that is not right. This is the same story that another friend came up with, his best mate (trader) buys ex motability cars and has had his fingers burnt by 3 VW 2.0 TDI oil pump (£6 pin) failing on cars he has sold - and countless 1.2 petrol chain problems - he too is turning away from VAG products (as a trader). Why are some people not talking to VOSA about this as I hear that VOSA are looking out for hard facts from drivers about 1.2 TSI engines shutting down at high road speeds - any engine failure at high speeds is a safety issue. I just hope VAG pick up the pieces soon as return to making reasonably reliable engines - maybe that is why I aim to buy an "old school(ish)" Audi A4 3.2 soon.

This same trader thinks that the same oil pump drive system is used on the 2.0 petrol engine - but I was not aware that that engine, in its current guise, suffers any nasty surprises like that.

Go for the 1.9TDi 130 bhp. Less problematic than the 2.0 and cheaper to run. With a little regular preventative maintenance it'll give you years of service.

Buy one, drive it for a month .... then have it remapped and smile. Seriously though, the remap will be noticeable. It won't turn it into a monster, but it gives you a lot more confidence overtaking etc. Mine pushes around 175bhp now and I can still get over 60 mpg (reported).

As to why the dealer may advise you to buy the 2.0 ... well I suppose it depends on the two cars they have for sale. The easiest way to find out why they're pushing the 2.0 is to ask them.

If they are pushing the 2.0 then you might be able to strike even a better deal on the 1.9 if you go for it.

The dealer needs to shift the 2.0 PD to a mug.

Absolutely he'll want rid of it, but what I meant was - I'd like to know what rationale the dealer actually gives for recommending the 2.0..., presuming he tries to give a reason, rather than a completely unsubstantiated claim

Depends on two things.

1. If the question is asked.

2. If he can BS someone with the answer.

In my humble opinion.

Does anyone know it this problem has been sorted for the Superb II PD engine, I know the CR is a better engine to go for but the PD is more available and cheaper?

The Superb II PD engine suffers the same problems even though they tried to fix it...

Not correct, the Superb II PD engine does not suffer from any of the problems of the MK1. We have had no reports of any issues with the 2.0PD engine in the MK2, the PD140 in the MK2 is a very different engine to that in the MK1 and is more or less the same PD140 used in the Octavia MK2 which again has never been shown to have major mechanical issues apart from the odd turbo failure.

I would not be prepared to spend any of my money on any PD engine fitted with Siemens injectors.

The piezo version of the VAG unit injector uses a crazy double lever system to obtain adequate servo valve lift with a short stack. This is unlikely to have the same durability as the direct acting Bosch solenoid controlled unit.

The real killer is that VAG/Siemens obviously forgot that well used lubricating oil in a diesel engine is conductive because it's full of soot. On a normal diesel it would not matter as the injectors are external, but the PD injectors actually run in the oil. Any sealing deficiency in the piezo stack will let the oil in and cause a short circuit - stopping the engine if the ECU has no reversionary mode. This was the basis of the 2.0 PD recall which VAG had to be kicked into implementing - nice people to do business with.

I am totally unconvinced that this injector design will ever be fully reliable as it has several design stupidities not shared with the Bosch units fitted to the 1.9. Note that the 2012 VAG Passat diesels which are sold in the US have reverted to solenoid injectors - I wonder why...

The American Transport Authorities don't mess with these things - unlike our spineless VOSA. VAG have been kicked in the teeth by them in the past and probably would not want to go there again, hence their decision to use a safe technology in that critical and sensitive market.

I would recommend spending your hard-earned cash on reliable technology - and in an ideal world spending it with a supplier who treats their customers fairly.

My comment was based on a friend who works for VW in Denmark and he says the new ones also suffer critical errors. He might be referring to the turbo failure you pointed out, i don't know. :-)

Indeed,

The engines suffering oil pump/balancer shaft module drive failures are diesels using the "Audi" North/South engine orientation which includes the Superb MKI 2.0 diesel. The Superb II uses the transverse engine orientation which does not have the the balancer shaft module.

VAG tried to make the Audi (A4 & up) 2.0 diesel smoother and more refined by introducing balancer shafts. Unfortunately these are part of a module that shares a chain/hex drive with the oil pump. The considerable additional load causes additional wear and almost certain failure with catastrophic results.

In short don't touch the 2.0 diesel.

The most reliable combination by far is a 1.9 diesel with a 5 speed manual gearbox.
