VW 2ltr TFSI DSG......any issues?

[98elise]

We're looking at a VW Eos 2ltr TFSI later today, with a DSG gearbox. Are there any issues with these that I should know about?

Looking on the web there are various valve coke issues which seem to affect all FSI engines, but is there any other known problems with tese engines/gearbox?

We tend to hold onto cars, so reliabilty is a must for us.

Some cars have major problems with leaky roofs. DSG gearbox for a long term keeper? No!

The engine and gearbox combo is pretty solid, had that in my GTI. Few minor problems like turbo diverter valve and PCV but these are cheap and easy fixes. Make sure the DSG oil has been changed every 40k miles.

My faultless A3 TDi DSG with 150k on it suggests contrary to this "but I read it on the internet" opinion. For the millionth time: DSG gearboxes, diesel engines, VW products, they're all perfectly reliable and good if you get a good example. The internet will tell you of DSG gearboxes abducting Maddie McCann and diesel engines murdering black teenagers in Missouri, but it simply isn't true.

Many years ago, Saab built a car with a two stroke engine. That idea was swiftly thrown in the bin. DSG has been around for, what, 15 years now and it's more common than ever. st ideas generally get filtered out. VAG is a business, an entity concerned with making money above all else. They aren't going to spend billions of pounds hiring the finest engineering minds on the planet to develop and refine an idea which will end up on the cutting room floor because it's so flawed as to be a waste of time.
DSG is as removable as anything else. We're talking about VW here, not Delboy and Rodney. They didn't just release DSG and hope no one would notice that it's made of Double Gloucester, all the while local A roads the length and bredth of this sceptred isle are jangling along to the dulcet tones of discarded metalwork vomited up from the bowels of what was formerly the DSG gearbox in a VW bloody Touran!

If it's got FSH, looks as though it's been taken care of by the former keeper[s] and you're willing to offer it the same courtesy as you would any other highly comlex piece of craftsmanship, then buy it, enjoy it and damn what The Internet tells you.

The TFSI lumps can apparently coke up although ours has been fine. Also, they often use a fair bit of oil which is not in itself a problem but does mean a significant number have been run low. I remember reading somewhere that the later engine which have a chain driven cam can have some sort of problems with the chain (ours is a belt so I didn't look into it in any depth).

I had the 2.0 TFSI engine in my MK2 Octavia VRS - great engine (torquey, smooth, etc etc) but as has already been mentioned drank oil like it was going out of fashion. It was on long life servicing, but to be honest by the time it came to get it serviced, I doubt it even had a drop of the original oil in it as it drank it so much. I think the trick with them is to go to fixed servicing schedules and go to a slightly thicker weight of oil! Otherwise it was sweet.

I think oil consumption varies wildly. Ours uses about a litre every 3000 miles of mostly town driving which isn't too bad. From what I've read some are considerably worse.

The engine has a lovely shaped torque curve for a turbo but quite a lot of high-rev turbo lag, if that bothers you. Probably not an issue in something like an EOS whose chassis isn't going to encourage hard driving anyway; it's a nice engine for cruising.

I was (possibly incorrectly) told it was something down to how the engine was run in, and on what sort of oil. Really no idea how true / feasible that is!

I wouldnt worry about the gearbox too much. I do like the engines but there is a known issue with coking up I believe. A few interesting pics here:

On newer engines I think theyve added an indirect injector to alleviate this. Not sure which models though.

Thanks for the advice. It turns out the car was actually a TSI, and the DSG lacked steering wheel shifters so it was not what we were looking for.

The dealer got my back up straight away by having it priced £500 more expensive than in the advert. I pointed it out and he didn't seem bothered. I hate dealing with car salesmen.
