140ps diesel gasoil Tiguan great 4WD car new to OC but watch for faults arising

[toni2has]

Currently has engine check light on just a month out of VW UK 3 year Warranty will be taking to local VW agents Monday next watch ths space on getting problem sorted as I believe it should be totally under Goodwill. The problem could be anything from wiring faults to lambda probe failure or even worse and ECU or exhaust component failure.

Anyone out there with a 2.0 tdi diesel Tiguan Jetta or similar had this fault yet?

I have had VW's new and old since 1967, and water cooled including Audi's new and used since 1995. Will be interested to see if my commitment to the VW (VAG) brand is respected by VW UK?

toni2has, you seem to be determined to splatter this all over every forum you can find. How about you wait until you actually find out what's "wrong" before deciding that VW is getting more faults. I would also point out that newer cars have far more sensors and electronic doohickeys to "go wrong" so it's logical to expect a few more failures in comparison to older vehicles that don't "have them" !!

Hope your problem is easily and cheaply cured.

Cheers

A reply to Derek from NZ.
Many thanks for your observations, but at no time have I stated that "VW is getting more faults" as my message was one intended to raise awareness of what could potentially be a particular problem applying to the 140ps. You should have apprecaited my vehicle is an early UK VW model and is over 3 years old. Hence, the failure may be indicative and anyway identifying the problem through only two forums VW Tiguan Technical and New Owner is hardly "splattering over every other forum" as both cover specifically the Tiguan and both seek constructive advice. Naurally I said the Tiguan was a great 4WD car as it is but I also pointed out my loyalty to the VW mark, which in practice is probably FAR greater than the majority of the forum members and readers.
Thanks anyway best regards.

AND what WAS actually wrong with your Tiguan ?? Mine is over 3 years old, diesel by the way so I do know a little about them. Quite sure I'd seen your post on other forums as well as this one ? but if not you have my apologies (update, I was correct this same post is in other forums as well, which is what I had meant in my comment).

Would still like to know what was actually wrong with yours ?

Cheers

Hi Derek, all
Unfortunately the problem is not unheard of as I suspected. Having discussed with other owners of later VW diesel models equipped with diesel particulate filter systems (DPF), including Passat, Touran and Jetta owners, it appears that a number of problems can arise. From what I have been told these could prove extremely expensive to solve, I have had heard figures of UK £150.00 to £1200.00 plus quoted, presumably the latter includes the cost of a replacenmebnt DPF? By all accounts if others are to be believed the problems are not always readily solved by resetting the system after repair and replacement work! It would appear as I understand it, that the sensor that controls the recirculation and reburning and controlled discharge of reduced sooty particles captured in the DPF has probably failed according to the diagnostic output. This presumably will allow a build-up of sooty particles in the filter unless the sensor is replaced and the system reset or perhaps engine and exhaust and operatiung conditions allow for discharge through the exhaust. Apparently it is not unheard of for vehicles to go into what is referred to as "limp-mode" or "safe-mode" where performance is severely restricted and perhaps is aimed to prevent damage and to emphsise the problem should be addressed ASAP. It is possible other warning lights may illuminate for example; the catalist / exhaust symbol may come on together with a message in the central display panel stating something like "Diesel Particulate Filter-Instructions!". In my case I do have an offer of a "Goodwill" contribution from VW. Subject to further discussion I intend to take the vehicle to my local agency / franchise for rectification this next week.

On pluease the usual "cure" for the dpf getting clogged up is a blast on the open road for a few km to burn it off, usually takes care of itself but "yes" the sensor can fail and cause it not to regenerate itself, I think I've heard of this on 1 Tiguan that actually needed a replacement dpf and that was very expensive. Common ? hell no. And yes the "limp mode" is to allow you to get home or to help, it's better than just switching itself off and refusing to move.

Still totally uncertain what's actually wrong with your Tig ? is it just that the check engine light is on ? and have you had it checked ? and what did they say ? does it have a dpf failure ? in which case how come you're driving it ? does it have a dpf sensor failure ? in which case it's a two minute fix job ? or ? ??? So far you haven't said a single thing about what is actually wrong with your Tig (other than the warning light being on), just a list of things that could potentially go wrong with it. Sorry but I'm as confused as I was with your first post and I'm still interested to know what's actually wrong ?

Cheers

Hi to Derek in NZ and to all other Tiguan owners.
In short the failure on my 2008 SE 140PS tdi was indeed the DPF sensor and it was subsequently replaced by a local VW franchise after having been told it was OK to continue to drive the vehcle. With a little persuasion VW UK did offer a significant percentage toward the replacement cost, although I did think the initial overall cost was slightly excessive. However continued to run the Tiguan with low annual mileage until April 2012 when decided to sell it through a trade broker, its now on sale with another UK VW franchise some 200 miles away. The reason I sold it was primarily due to the issues I had raised concerning low mileage use diesel vehicles involving very potentially expensive DPF failures, which incidentally have been identified by both the trade and the AA organisation in particular. Despite my trying to find a petrol equivalent Tiguan at the right price and of similar age I was unsuccessful so sold the vehicle. Observing the way the global economy was heading and realising that paying out large sums to purchase a new vehicle was not the ideal, I decided on purchasing a Mercedes ML with high mileage and being over 10 years old with less engine management gizmo's but it is built like a tank has greater space and carrying capacity and being a 2.7 litre diesel pulls well with similar consumption to the Tiguan on short journies and slightly worse on higher speed longer ones but day to day its hardly noticeable. Incidentally for the record the Tiguan was the 15th VW / Audi group vehicle owned since 1967 with one Audi 80 in particular reaching 14 years before selling it on and I have carried out virtually all aspects of maintenance and routine servicing including rebuilding engines. We can even vouch for the safety of VW's as my Wifes former Bora V6 4Motion safely carried her through a 30mph plus frontal square-on impact with the corner of a solid brick wall with very minor bruising suffice to say we bought another VW Bora V6 4Motion (ex-Police) within a month or so of the accident and it is going extremely well.
