Audi a3 2.0 tdi S Line starting issues.

[Louise]

Hi, I'm looking for help, I have an audi 2.0 tdi S line 11 plate. Recently I've experience starting problems but only when the engine is warm/hot. I've had the fly wheel and clutch done and a new starter motor too, this hasn't sorted the problem. When I crank it sometime is starts perfect, sometimes it starts noisy with an engine shudder and sometimes it doesnt start at all. I've attached a link to a youtube video that been uploaded by somebody else, this is exactly what's its doing. Any help would be greatly appreciated as I'm pulling my hair out. Many thanks

Hello Louise, 

Sorry, cannot open the link at present, but is the starter spinning the engine over enthusiastically? I would guess so, but..

Hot starting issues should be easier to diagnose than cold starting, but the offending component could be one of many, so I would certainly not be jumping to action any suggested possibilities. 

If it were mine ( and apologies to those who have to continue to read this) I would be seeking out a trusted local diesel specialist - not Audi independents- and entrusting  the diagnosis to them. Local taxi drivers are a good source of who to take it to and who to avoid. The taxi boys depend on diesels, so they should know their way around specialists. 

Clutch, starter motor etc. renewed? Surely, not in an attempt to sort the problem? 

One last point. When the car does eventually, do you have any excessive exhaust smoke, and if so, what colour? 

Kind regards, 

Gareth.
