Interesting. Unfortunately the pump on my car is a LuK and doesn't have that screw. :(

OK, looks like this is the last issue to solve on my car. My car has been hard to start lately. It sounds like it loses prime, as I hear what sounds like air bubbles when the lift pump comes on during the glow cycle. Doing 3-4 glow cycles seems to have little effect. Lift pump, fuel filter and...

Looks like I'm winning... :) Just a small update. I got 1L/100 km better fuel consumption since the turbo/head work was done after backing off the torsion to +1.0. Changing the O2 sensor seems to have eliminated the cold running smoke show! Hoping for better fuel consumption numbers too...

Hi Owain, The coolant level is OK. Original cam and the shop that did the work said it was OK. The car has 192k kms and bone stock. White smoke definitely smells like diesel. Regarding injector deviations, what is acceptable and what is excessive? I've been getting inconsistent numbers most...

Hello, I've been working through a number of issues and symptoms with my 2006 Golf since a turbo change and head work. I've solved quite a few, but poor fuel economy and a smoke show while warming up are still there. The smoke is white and appears as the car is warming up to 90C, but lower in...

Hello, I borrowed a friend's VCDS and I can't find the torsion value in Group 4, as described in other posts. In the version I have (17.1.3) in Group 4 I see ignition timing in block 2, and idle stabilization in block 4, where torsion value apparently is supposed to be. I read somewhere that...

Anyone in the Ottawa/Gatineau area have VCDS that I can borrow/rent? 2006 Golf TDI

Lift pump is brand new.

re. DBW, I know, just worth a shot since nothing else was happening. ;-) I still haven't seen an check engine light during any of my troubles. If I don't solve the problems this weekend, I will get VCDS and start poking around that way. Cheers, CK

Small update: the car has been running fine this week. New problem: I had to crank it for a long time and put the gas pedal to the mat before it started cold yesterday. Once it did start, it did so quickly and smoothly, so I don't think it's glow plugs (it was -10C last night). When...

That wiring harness under the valve cover always concerned me. Looks like an easy target for eventual damage. Where does this harness ground to? Might be good to check the ground at the same time. Thanks to you and Mike_04GolfTDI for the tip! CK

That would be handy, but I don't have VCDS. Guess I'll have to pony up for the software and cables at some point. Which torsion setting is this, and where? Any other obvious physical signs to look for? Thank you, CK

Hello, Following a significant overhaul of my 2006 Golf TDI with the BEW engine (new turbo, head reconditioned with new valve seals/seats etc, cam bearings, new lift pump, new fuel filter) my car occasionally runs rough when shifting from 2nd to 3rd. It also happened yesterday while...

Hello, I'm considering getting a used Touareg TDI so that I can tow my race car with it and still have something relatively fuel efficient for the other days I drive. I notice the 2011+ has an 8 speed transmission while the earlier models have a 6 speed. Is there a difference in...

If I recall correctly I did have the door open as I cranked it. The evening after I started it in -22C after two tries. No extra glow cycles this time around I just waited for the glow plug light to shut off and then cranked. It turned over very slowly the first time with no firing and I...

I installed the Evolution Import skid plate on my 2006 Golf TDI PD. It's already saved my ass a bunch of times, from bottoming out on rally stage roads to running over parking lot curbing buried in snow. Everyone who owns a Mk4-6 VW should put a steel or aluminum skid plate on their car.

Hello, This morning at -25C my car wouldn't start. I glowed it twice (not sure if I needed to do this but it helped on my Mk1 diesel many moons ago. This is my first diesel in 20 years). As expected it cranked very slowly and didn't speed up. As it slowed down all sorts of lights came on...
