When VW pulled We Connect Go I lost my logs, so I built my own app — for us diesels it keeps an eye on the DPF

4 Upvotes

Hi all. When Volkswagen shut down We Connect Go at the end of last year, my whole trip and fuel history went with it. No export, nothing. I'm a developer so instead of moaning I rebuilt the thing I'd lost, with one rule: no servers, everything stays on the phone.

Posting it here because the diesel-specific part is where it earns its keep. With a cheap OBD2 adapter (a standard ELM327) it reads real consumption straight from the ECU, actual litres in the tank, battery health with history, and fault codes explained in plain words instead of just a P-code. And for us it watches the particulate filter: it tells you while a regeneration is running so you don't switch off mid-cycle and leave it half done, and it keeps the history of the cycles.

Without an adapter it still logs your trips automatically, tracks where you parked, and keeps a service logbook with mileage and costs. No account, no ads, no tracking, and you can export everything as JSON or GPX whenever you want.

It's on the App Store here: https://apps.apple.com/app/id6776173662 (Android is in closed testing right now, out soon). Free to try, one time unlock, no subscription.

One honest note: you need a normal OBD2 adapter, not the old VW DataPlug (that only ever talked to VW's own app, which is now dead). Happy to answer anything.

I cant connect to these modules in obdeleven, i tried the good old battery disconnect trick but no luck. I dont know if it is related but cant do dsg relearn too, when i start the procedure i never get "completed" and obdeleven gets stuck on "procedure on" and loses all transmission module infos. Help! I just bought the car and the shifting feels weird.

2015 6spd Passat - massively different towing capacity EU vs NA models?

0 Upvotes

I've got a manual transmission 2015 Passat TDI bought new with roughly 160k miles on it. It was manufactured in their TN plant in the US. I love this vehicle, it's been amazing.

I'm moving from southern California back up to Canada and would like to install a trailer hitch and rent a 5x8 or 6x12 uhaul trailer to move my stuff. I was rather surprised to learn that the North American version of this vehicle is limited to a maximum towing weight of 1000lb, including a 165lb tongue weight according to the owner's manual. The door sticker states the GVWR is 2100kg.

The 5x8 trailer weighs 900lbs empty, while the 6x12 trailer is 1900lbs, which makes either option a non-starter.

I'm reading online that the EU market version of this same car has a 2000kg (4400lb) tow capacity, and I am here to ask how could the same vehicle in a different market have such a different tow capacity? I find it very hard to believe that the EU version of the vehicle has a significantly different design or seriously beefier suspension. Is the difference about the ability to use a trailer brake (neither of the u-haul trailers have their own braking, but I am sure I can find and rent one with a brake if this helps).

1.9 TDI injectors

1 Upvotes

I’m planning to replace the seals on the injector; the car is a 2007 Passat B6 1.9 TDI, engine code BXE

In the official manual, they mention that the bolts holding the injector should be tightened to 3 Nm + 270°, but on forums I keep seeing 12 Nm + 270°. 3 Nm seems a bit low to me, so I'm wondering if anyone has done this and what torque spec you tightened them to?

Mk6 Headlight Information help.

1 Upvotes

I have a Mk6 JSW (I call it a GWABA, Golf With a Big ... Butt) and the dash told me to put new highbeam headlights in, so I did, it then told me to put new DRL bulbs in, so I did that. Now it keeps telling me to put those lights in. I don't seem to have the ability to clear the dash. I tried obd11 pro, and it says nothing is wrong. I cleared all the codes and it made no difference, I looked into the service alert pages, I see nothing about headlights.

When I scan the car I get a module fault for the drivers side back door, but again, nothing about headlights. Do I need to replace the module even if it is showing faulty? I would be will to try but I see WILDLY different pricing on the different modules. How do I get the car to stop squawking at me?

P0402 Code

1 Upvotes

My 2014 VW Jetta TDI has been throwing the “P0402” code ever since my mechanic replaced the entire DPF system. I’ve had new gaskets put on as well and also had a separate mechanic clean the MAF and EGR Valve but it is still throwing the P0402 code and no one can pinpoint where it’s coming from. Anyone have any experiences with this issue and what be causing it?

2015 Jetta S TDI 167K

0 Upvotes

Found a TDI on FBMP in my town, only thing l didn’t like that it was DSG, $4500, title in hand. Went on Been Verified to check on it to see if l could find maintenance records ( zero) but did see that it had been titled 11 times, all East Coast except for an AZ and a WV title consecutively. The mileage only upped 20-25 miles between the 2 titles from AZ and WV so l suspect title washing.Anyway, despite being underpriced by 3-4K, l’m going to have to pass on this one. Anybody else have a similar situation?

P0299

1 Upvotes

Hey guys, I ran into a problem today. Was driving the car as I normally would on the highway on cruise control 100kmh. Then I’m going up a hill and as normal the car would accelerate the stay at 100kmh. Not this time, I heard a sound and the car stopped accelerating and seemed like a problem with the transmission. I pulled over to the side switch off and on the car and continued but the car was jerking like crazy and wouldn’t drive at high speed max it went to was 80kmh. Drove it for 5 mins, then the limp mode light came on, but the transmission was fine after that, the cars power was just lower. I did switch on the car on and off at the end and the limp mode was gone but haven’t driven it yet. So no jerking anymore but low power output. Some issues I noticed 3-4 days ago was that the car was in regen mode for a while and was blowing white smoke a lot, more than usual. So I got this liquid you put in the fuel tank to help with the regen, but other than that no issues. I got the OBD and it gave P0299 code.

Anyone had similar issues please help

Maintenance idea questions

2015 vw golf manual tdi 123,000 miles new timing belt water pump etc. oil changes done regularly filters new.

Was driving normal not beating it, took it out of gear to shift and engine shot up to 5000rpm briefly blew some smoke out the exhaust. Went back to normal drove a bit more briefly happened again, shut the car off as it was happening. Started right back up no issue and drove cautiously without issue for ten minutes until home parked and now working through diagnosing. (Wasn’t in a safe place to stop and wait for a tow no pull overs, a lot of blind curves and was relatively close to home. But yes I acknowledge driving it wasn’t the best option)

Going to re check codes this weekend but here’s what was previous.

Have a code for an intake manifold flap motor, wheel speed sensor both a week old and have the parts to deal with but giving all the details.

Had a dpf light on the dash went through the cleaning it out attemp to atleast get a temporary solution.. I say had because after the rpm shot up and smoke briefly rolled out.. the light went away and hasn’t come back on, but again I have to run codes again..

Thanks in advance I’d really appreciate any incite or advice as the cars been solid and issue free since this random occurrence.

Diesel Purge Question

Enable HLS to view with audio, or disable this notification

1 Upvotes

Looking to do a diesel purge on my 2014 Passat, but the fuel hose design on the CR170 looks a bit different than the CR140 guides I've seen online. Can anyone tell me which lines are the return and supply lines?

Also, follow up question. I've heard some people just change the filter and prime the filter housing with diesel purge instead of running it straight from the can. I thought of doing that, but wouldn't that just dilute the Diesel Purge since the return lines returns stuff to the fuel tank?

Sorry for my voice in the video, I've got a bit of a cold at the moment.

New daily for me

My 2012 Passat has been my driver for over a decade now, almost 160k miles by me, 250k total. The ONLY issue with the car is the rust. So I was casually looking and this one popped up. Couldn't resist. Should be good for another 10 years now.

This one is a 2014, 100k miles on the nose, Rawtek and stage 2 with DSG tune, headlights, wheels, etc. Couple of minor things I need to clean up but it's absolutely fantastic.

I have a slow coolant leak that was pressure tested but they couldn’t find source of the leak. Said most likely an ECG? Leak and would have to take a lot out and $4500?? Independent German auto shop. Next I’ll take to dealer for leak inspection too. Any others go through this and recommendations? I just keep topping off the coolant.

Dashboard consumption mismatch after camshaft replacement

2 Upvotes

Hi all!

Recently my 2.0 PD TDI engine (BMM) went through an overhaul. The engine received a new camshaft, rockers, the intake was cleaned, new timing belt set etc. After the repair the dashboard reported l/100kms went up by 2l/100kms.

The full tank method shows that the mileage isn't that bad, but it's still higher than before the repair (closer to 7l/100km) and also the car doesn't feel as snappy as before. VCDS parameters check out, nothing out of spec.

What are we missing? Has anyone encountered any similar issues? Thanks!
