Owners of some Volkswagen TDI models are experiencing premature selective catalyst reduction (SCR) failures due to the fact of AdBlue heaters that, in some circumstances, are not lasting more than 50,000 miles.
According to a source who spoke to TTAC under the situation of anonymity, several Volkswagen TDI owners are arriving at dealerships following seeing check engine lights for failing AdBlue (diesel emissions fluid) heaters. Those heaters, explained the source, fail “based a lot more on time than mileage” and expense more than $ 1,000 to replace.
The price of the parts and labor is a slap to the face for numerous TDI owners, as SCR systems in those automobiles are not scrubbing the required amount of NOx from diesel exhaust even when the AdBlue heaters are operating properly.
The AdBlue heater in question is covered below warranty for up to 36,000 miles or 3 years, whichever comes very first. However, numerous of the failures are happening just outside of that warranty window, at about 50,000 miles or four years of ownership.
With the improved focus on Volkswagen’s diesel emissions, numerous have taken to the National Highway Traffic Safety Administration’s complaints website to explain their troubles and voice their displeasure with how Volkswagen is handling the situation.
NOX SENSOR MALFUNCTIONED OUT OF Variety CODE. WAS QUOTED 655 DOLLARS TO REPLACE. NOX SENSORS ARE NOT Essential BY FEDERALLY MANDATED 80K EMISSIONS WARRANTY SO VW Won’t Incorporate VOLUNTARILY. A single WEEK Following Obtaining THIS FIXED, THE Verify ENGINE LIGHT TURNS ON Once more WITH CODE P203B, REDACTANT LEVEL Range/Performance. SPEAKING A Couple of Occasions WITH TECHNICIANS AT THE DEALERSHIP, THIS Probably Indicates THE REPLACEMENT OF THE AD BLUE HEATER UNIT AND TANK WHICH IS More than 1000 DOLLARS. Once more, NOT COVERED Beneath WARRANTY.
THE Check ENGINE LIGHT CAME ON 9/10/15. I BROUGHT THE Automobile INTO THE DEALERSHIP ON 9/12/15 AND Discovered THAT THE CAR’S ADBLUE HEATER HAD GONE AND WILL Cost JUST More than $ 1,000 TO REPLACE. THE ADBLUE HEATER HEATS THE ADBLUE TO Eliminate NO2 FOR EMISSIONS, However VOLKSWAGEN IS CLAIMING THAT THIS IS NOT COVERED Below THE EMISSIONS WARRANTY. THE ADBLUE Technique HAS NOT OTHER Objective THAN FOR EMISSIONS AND Should BE COVERED Below THE FEDERAL WARRANTY, AS THE EMISSIONS WOULD FALL Outdoors OF THE FEDERAL REGULATIONS With out THIS Component. Proper EMISSIONS Assist TO Preserve OUR Whole POPULATION Secure AND Healthier FROM THE Damaging POLLUTANTS GENERATED BY Cars.
THE Check ENGINE LIGHT CAME ON AND I HAD CODES Study. THE CODE WAS P205C AND THIS INDICATES THE EMISSIONS ADBLUE HEATER AND SENSOR HAD A Problem. THE UNIT (HEATER AND SENSOR) IN THE ADBLUE TANK IS A NON SERVICEABLE UNIT AND Need to BE REPLACED. Over $ 750.00 TO REPLACE. ALL THE EFFICIENCY OF TDI JUST WENT UP IN SMOKE. Occurred AT four,000 MILES Previous WARRANTY AND DEALER HAD NO Assist EVEN Though A LOT OF TDI’S ARE Having IDENTICAL Issues. Appears TO BE A DEFECT IN Style, Many Many TDI’S ARE Obtaining THE Same Issue.
An whole ClubTouareg.com forum thread is devoted to the failures.
Forum user TouaregRoadie says:
My dealer-maintained, IMMACULATE 2012 TDI Lux just went in for a verify engine light and the diagnosis was the AdBlue heater has gone poor. I have 51,000 all-highway miles and was shocked to learn (as are numerous soon after reading on these forums) that this portion is not covered under the powertrain or emissions warranties.
Fascinating to note, this happened within a week of my 50,000 mile service at the dealer. Coincidence?
Following calling VWoA they came back with an offer to cover the parts (about $ 1,000 of the $ 1500 quote after labor and shop fees).
In light of the negative press that VW is having with the EPA at present on it is other TDI models, I’m wondering how numerous of our cars are experiencing this problem, and how numerous of us would it take to get VW to repair this by way of recall?
In a lot of situations, like that experienced by TouaregRoadie, Volkswagen appears willing to pony up for the cost of components, but only in certain situations.
Our source explained “a good dealership will be in a position to receive goodwill help for loyal clients with beneath 70,000 miles on their automobiles. But soon after 70,000 miles or so, there hasn’t been any goodwill help.”
A diesel vehicle owner’s chance of receiving help for an AdBlue issue, or one particular of the several injector failures resulting from bad diesel fuel, is mainly dependant on a dealer’s connection with Volkswagen, and much less on the customer’s loyalty to the brand, said our source.
Because 2012, the model year which has seen the most AdBlue failures to date, Volkswagen has redesigned the AdBlue heater and replacements shouldn’t run into the exact same issue in one more 50,000 miles.
That’s not considerably comfort for the many thousands of Volkswagen TDI customers. Shelling out $ 1,000 or far more to maintain a automobile compliant with emissions law is one particular issue. Doing the exact same and nonetheless not getting compliant is something else entirely.
As of nowadays, we have stopped reaching out to Volkswagen Group of America for comment.
In the months because the diesel emissions scandal broke, we’ve given VWGoA each feasible chance to supply its side with regards to quite a few stories. Recently, those requests for comment have gone entirely unanswered. As such, we will no longer be reaching out to VWGoA for comment.
Volkswagen knows how and exactly where we can be reached, and they’re welcome to get in touch with us at any time.
