DieselGate The news broke that VW lied about emissions on their 4 cylinder TDI cars across the world. Cars were being put in a different ECM strategy for the test. Here are my thoughts and how it will impact you, me, and others. The great thing about this whole dieselgate thing is, VW admitted that they lied about it, and has promised to make it right. I really hope they stand behind that statement.

I am a dealership employee, NOT a VWofA employee. I do not have access to any top secret information. All of the things I talk about today are public knowledge. They are also only my thoughts. I am not speculating on anything that VW may do to fix this issue. There are a lot of things that could be done, but we just do not know what will happen.

Join me today as we breakdown:

  • What this DieselGate thing is all about
  • How VW may have cheated the emissions test
  • They admitted they did it
  • What they promised to do.
  • How this will impact VW service people
  • How this will impact VW sales people
  • Will they really make it right?
  • What will the Recall on TDIs mean
  • Great forum thread at CleanMPG.com
  • and more

Humble Mechanic Logo

Last week my dealer got their first TDI A7 Golf, or MK7 Golf, OR MKVII Golf. Did I get all the ways to say that it is the 7th generation Golf? LOL

The new Golf and GTI are now built in Mexico. To me it is weird to see the VIN start with a 3, that is New TDI Golf Enginethe country code. We also see several new technologies on this Mk7 platform

  • New series of engines
  • Modular Infotainment System (MIB)
  • Proactive occupant protection
  • Selective driving mode (only on the GTI)

But today I want to focus mostly on the TDI. When we get a brand new car in we do what is called a PDI Perfect Delivery Inspection. For me this is a great opportunity to look at some of the new and cool stuff. I mostly focus on all the things that VW did to make my life hard. Like dumb oil filter locations, or plastic oil pans (yeah, and I still salty about that).

So lets look at some of the new stuff on the TDI.New TDI Golf Engine

For the first time the Golf TDI has exhaust fluid. The Touareg and Passat TDI both have had AD-Blue for years. The thing about the Golf is the location of the filler. VW has moved the filler right next to the fuel nozzle. My thoughts? Well, now instead of spilling Ad-Blue in the trunk, you get to spill it down the side of the car. Kidding about that part, I actually like the move. It means I will not have to move a bunch of things to fill the Ad-Blue tank. Plus the fillers are VERY different.

Oil FilterNew TDI Golf Engine
This is a move I didn’t see coming. For the first time since I have worked for VW, the TDI oil filter is NOT on the top of the engine. This is a strange and weird thing for me. So I know what you are thinking. They moved the oil filter to a really easy place. WRONG! They moved the filter to the bottom, but it is now it’s buried by coolant hoses.

From a mechanics point of view, those are the most important changes. There are a few other things that are different. The TDI now has a water cooled charge air cooler. That is something the TDI Passat has.

Overall I think the new TDI Golf, along with the GTI, is a great platform. I hope that we are past the diesel fuel and HPFP issues at this point. But only time will tell. .

Tdi Diesel fuel system High Pressure Fuel Pump Failure

Happy Tuesday everyone. As you read this, my area is getting ready for a big snow storm. For the southern USA, this has been a crazy cold winter. We even seen temps as low as 8F. I know that some of you folks are cracking up right now. But for me that is record cold. With such cold weather, we have seen a huge run of issues with VW diesels. So today is a little about diesels and a mini Shop Shots, all in one. I have always had mixed thoughts on VW diesels.

Tdi Diesel fuel system High Pressure Fuel Pump FailureLike I said you are getting a mini Shop Shots today. This is a picture of the inside of the high pressure fuel pump HPFP on a TDI Jetta. While this is not a cold weather problem, we have had a run of them at my dealer. For those that think this is due to gas, I assure you none of the last 5 or 6 had gas. The metal bits in the fuel are from the gut of the pump. We have even seen a Passat TDI and a Touareg TDI with fuel system failures. These repairs run from $4000,-$8000. VW has been covering most of them so that is good for customers  **DISCLAIMER** I am not saying that VW is, or will cover this repair for you, or anyone you now.

VW TDI Cold weather kitMoving on to real cold issues with the Common Rail TDI. I posted this on Facebook last week. This is an updated charge cooler, intake pipe and some tubing. The issue is moisture freezing inside the cooler. This can prevent the TDI from starting. It can also go as far as causing major engine damage. We a Jetta at the shop now that we suspect having a bent connecting rod. It seems a small bit of ice can get up to the engine and cause the damage. Based on conversations, this is not the first one out there. I will be sure to post a picture of the damage when the engine is a part

There is one more issue I have seen that seems to plague the TDI in cold weather. That is turbo charger failure on the Common Rail TDI Passat. We had a car towed in with a glow plug light, check engine light, and no power. The faults were something related the car not having any power. (duh, it had no power) I did some checking and everything electrical checked out. Finally I removed the intake pipe and found that the compressor wheel was completely seized. It should turn freely, heck when spinning at top speed, some turbos can spin up to 100,000RPM. I do not have any pictures of that yet. I should be making the repair on Thursday.

After reading this, you must think I hate the VW TDI. That is just not true. I think the diesels are great. They have good MPG, tons of power, and are super clean. But there is no denying they are having some serious issues. The one good thing I can say is, VW has been great in taking care of TDI owners.
