has it run low on fuel? also check there is voltage at the glowplugs when you turn igniton on, fuse may have blown.

Immobiliser Craig?

Car was running fine yesterday at about 12. went out tonight at 2000 and it never started. ??? there is plenty fuel in it. What voltage should be on the glow plugs. Where would i see fault codes?

 

[K7ERG]

Usually with the immobiliser cars dont turn over but dont know about the Audis.....

I had immobiliser fault and had the same issues.the car would just start and no more then cut out.tell tale sign was dash lights flashing and fault with Air-Con on and off.igition key would not recoil back properly........ignition switch below barrel was broken

Everything as it should be i think. Will check the voltage on the plugs and see how i get on. failing that garage it is as its too cold to be working on cars out side.

Need the location of the Glow plug relay?

I believe its behind the lower trim panel (above the pedals) there is also a large fuse there for the glowplugs. There should be 12 volts at the glowplugs.

 

[K7ERG]

Do i just measure the plug on each plug or do i have to take the plug out?
New to Audi diesels ;(

the connection is common across all the plugs, just connect the positive of the avo meter to the top of the glow plug and the earth of the avo meter to the engine block or some other good earth. no need to remove the plug.

Cheers will give it a go.

Check all 5 and all ok around 12volts. Started first time.???? Lots of smoke but it started no probs.

The only thing that has changed is the weather is milder around 2degrees and lastnight it was -5degrees on the display. Or i have disturbed one of the plugs for the Glow plugs...

Now what can i do to improve reliability?
It is in need of a service but the glow plugs, fuel filter and oil changed 2000miles ago.

Any pointers

I see people on about the coolant temp sensor

????

I see people on about the coolant temp sensor. Should i replace it as its still not the best at starting......
