Mk6 103TDi EGR

[degrees]

I'm looking at buying a 2010 golf 103tdi with around 70k on the clock and would plan to hang onto it for another 100k or 5 years. After thoroughly researching the DSG, I'm now investigating the diesel engine. After reading a nightmarish thread on mk5 EGRs filthing up the engine, I'm already hesitant. Does the mk6 still suffer from this problem?

In the interests of long term ownership, I'm also reading about owners routinely adding 2SO or Morey's Diesel Smoke Killer to every tank. Is this something mk6 owners are doing too and does it improve the EGR sludge/soot?

Hi degrees, welcome.

There arent a lot of users on here that will have the answer your looking for... probably Transporter has the most experience as he services VW's for a living and so can give you good advice.

I dont have personal experience with the CR TDI, but my workmate does and its been a great car for him - no special servicing from him just the right oil, thats all, 270kkm with no dpf or egr related problems.

There are a lot more out there working perfectly than the forums will indicate, naturally

So long as you get onto the highway weekly, or basically don't just do short low speed inner city driving you will be fine. Diesels are meant to work, and some higher speed driving helps keep the sludge down. The MK6 has had a LOT of improvements over the MK5, different EGR flap mechanism for a start. You can always fit a Provent 200, it's not super difficult.

I'm a big fan of additives to the fuel, but only to protect the high pressure fuel pump and injectors. Fuel quality matters a lot in the MK6 common rail in my opinion. As these engines are direct injection, no additive to the fuel helps clear the intake.
