Hello, I'm new to the forum so I can see this question is quite relevant but could be in the wrong place or duplicated, I apologise in advance.

Ive read through the Non start when Cold Posts looked at the Videos and concluded yup mine does that, I've only had it a week and in that time every morning has been below freezing, it has only once started without drama, every other time it cranks very well but does not show any signs of life, I am concerned the Starter will eventually give up, and its obvious why the car was up for sale. yesterday My Nipper and myself carried out a full service changing every lube oil and filters, this morning exactly the same, i've left the fuel cap loose (One suggestion) and yesterday we cleaned out the flap assembly where the egr valve is, we also noticed that a non return valve has been added in the fuel feed pipe so it looks like this drama has been ongoing, so has any one actually got to the bottom of this wonderful NON START??

Any suggestion even the totally ridiculous will be listened to, you never know................

Welcome.

This is a mainly US site tho' there are folk from South Africa and Oz on here who are very knowledgeable on the R5 but bear in mind that your model never went to the US so join the UK site too:

I'd be suspecting duff glow plugs but do you park the car on a slope? There are seals that go that then allow the diesel to go back to the fuel tank so there's no fuel in the system to start the car. Others will hopefully explain this better but I recall it's worse if the car is parked nose up the hill!

On your car, it is CRITICAL that you use EXACTLY the right engine oil - VW 505.01 or 506.01 if no DPF is fitted to avoid premature camshaft lobe wear.

Do take the time to sit down and read this thread carefully and completely ASAP. You will learn a lot and know what to expect:

Thank you for your reply, my bad that I have landed on the USA Site, I will have a rummage to find the UK one.

Welcome to Touareg world - it's no bad thing to be on both sites.

I agree with you, more action and replies here than the UK site

check the glowplug voltage

if no voltage, check relay and fuse

if you have voltage then replace the glowplugs

Went to a diesel specialist this morning, they reckon the Injector seals have gone, that would also account for the very thin oil when we changed it, so have booked it in for Thursday, we will see, been not to drive it until then.

This was the scan.

Replace return line from injectors with clear hose into a bucket. Let it idle. If there are bubbles, the seals are gone.

Camcap bolts and injector hold down bolts MUST be renewed as they are TTY.

Got the Touareg back today, Injector seals replaced at a cost of £249-30 GBP Car sales Chap has said he will pay 50% I'm happy, just have to change the sump oil and filter, job for tomorrow.

 

[4ePikanini]

I hope he changed the camcap bolts and the injector hold down bolts to new ones. They are use once TTY bolts. Reusing them can cause them to snap during use resulting in catastrophic engine failure.

Bought some cheaper oil yesterday and another filter, will let that mop up the rest of the diesel in the sump and around the engine then in a couple of days put the correct oil in with another filter, engine is a lot smoother more power and funnily enough not using as much fuel, minor result I do believe, and the original bad starting has gone!! Bonus. Oil temp is a lot cooler.
