2015 Jetta TDI 50,000 miles P20B7 - OBD II Trouble Code - RepairPal

[Larry Manton]

Morning all, and Merry Christmas.

Okay, don't beat me up yet as the code I took was just before I walked into Starbucks (-C here) and got it from my Launch Tech Cheezy one size fits all for on the road quick stuff on smart phone, and about half the time what it spits out is not exactly spot on, but any port in a storm.

But the code above is what it spit out. I have no idea what it is? (Reductant metering unit heat control circuit low). Thought maybe had to do with a secondary system like the glow plugs for heating coolant on my other TDI, but could be way off base.

Can and will send a scan but the car is on warranty and the dealer is on the hook, but some day I will be, and also need to get a wire diag for it. Have a nice day guys, you too Jack. LOL

VCDS would tell you: "Output Stage for Reductant Heater: Short to GND"

Merry Xmas Larrymore

That is a reductant DTC.
Check that urea tank isn't contaminated or wiring connections to injector are not faulty.
There maybe a strategy being deployed to cool the combustion process & if exhaust is to lean and hot based on high EGT reports.

Post an auto-scan when possible for historic data record.

Are you running octane enhanced fuel or additives which may induce this?

UWE, you spit that out like I would know, and now is clear is related to Urea system. as this is the first I have owned one and the trucks at work are right now Pr-urea so new too me but knew it was coming.

Jack, I do not run any adative in this unit, but was going to ask about that also. I sometimes do in my Dodge 03 5.9 common rail, and my ALH's but not all the time but sometimes in winter when they are grouchy. PS, Beetle with Jacks advanced timing status, and glow systems, starts at 25F, like it was hot, maybe .5 seconds crank, and bang.

Running around today but will do an auto scan, but as stated, light poped on today and wanted to know was this like and issue with a Raindeer on the roof, or something, meant nothing too me.

Need to know anyway as ususally Service tech are pretty cold, even colder if you know anything at all, but will end up in their court if broken. Also is the low temp an issue, as have had some classes on Urea and know it likes to freeze, and also boil, just another issue in the mix to deal with I guess.........Go VAG.

UWE, hope you are indoors for Christmas and not in that tent under a Cessna wing I think. Not good with vintage anymore, my dad owned a Fairchild PT-26, Luscomb, and a Stinson Voyger, yes I am old.

Will scan today and post today or tomorrow.

Jack, as a side note. Last week a guy dropped a block of concrete in front of me @ 40MPH, 6/6/12 inches my guess, hit it dead center LF Tire. took down his insurance and cop said don't see anything wrong.............I said I don't care what you see %^*%%$%.....it almost took the fillings of my head. I said serious damage under some of these cars can total it in short order, and you won't see any leaks either.

So this week, insurance giving me the cold sholder, I replaced at this time LF tire, (broken cords,) Damaged LF wheel and 4 wheel alighment and now drives true. I asked the guy at VW?? seing how this car is warranteed by you do you want too inspect it as the tire shop said the seen no damage under, and IMO, it spit the block out side the car after damaging LF tire and wheel.

Cop did not site him for unsecured load............1,000,00 if damage, occurs, 10,000.00 if injuries. I have insurance, but will bill his, then if a no go, go to small claims court, or just pay the decutable. The humerous side, think an oxymoron, is he is the owner of 8 Defensive driving schools, now that is funny.

My point being have seen core of cats on rigs at work broken loose internally from heavy impacts and not necessaily directly too the cat itself. My quest is......with no damage to the belly could this be colateral damage via shock. I can play dumb and not say anything but feel it is unfair for the Dealer to eat damage from this guy if this urea deal is related.

[Jack@European_Parts]

Consult a lawyer because it's usually free to check.
Last I checked police are limited with certifying cars are safe for tire wear, seat belts being worn & broken lights or glass, not an official vehicle repair shop or licensed motor vehicle station license holder or inspector as in NYS CR Law but I am no lawyer nor can I give legal advice.

Okay,,posting data on this...............also the DPF blue icon came on indicating it might be low. That said read in the manual that if it comes on along with a wrench it is indicative of problem with the system , which I have, but at this time have no wrench, just the trouble light.

Not having a wire diag yet, noted heater circuit #1, no voltage, would assume this should also be system voltage. Also one code on radio, opinions as is on warranty but radio seems to work good.

Also noted 73mm fluid level. Knowing there are 25 MM in and inch, then is this almost 3 inches of fluid, just trying to understand, and sure..........if it is like 15 inches deep then would be low.

Thanks Larimore
