Engine Cutting Out

Update is :- The a Engine has still NOT CUT OUT again !

Only that one time at approx 22 Miles after fitting the new Crankshaft Speed Sensor. So is the Fault that my A2 is not recording the fault ? Richard at Harpers Cumbria had the Gut Feeling that it would be the Crankshaft Speed Sensor breaking down causing the Engine to Cut Out. Expected their VAG Diagnostic Machine to find that. It did not, so he was reluctant to advise me to get it changed. The mystery is, why did it start the very day that the RAC fitted a new No 4 Ignition Coil ?

Will update if it turns out not to be fixed. Working Night Shifts next, so I usually take the A6 for the extra comfort driving home in the morning. ( 2014 A6 Avant S Line Black Edition, 20" Wheels, Bose 10 Speaker Sound System . . . . . . . .
Hi, my name is Stephen, I’ve been following this discussion with great interest. I have a Audi A2 TDI 1.4 on a 2004. During the winter months it became increasingly difficult to start. Thought it may be a battery problem, so gave it a full charge.

Manage to get it started, but now had the engine management light permanently on. The glow plugs warning light, flash continuously, so I changed them all. The car now would start and drive perfectly, although the glow plugs light still remained flashing.
Then the engine began cutting out whenever traveling at low speeds or stationary. Starting probably came back with vengeance, although after it would restart after between 10 minutes and in excess of an hour.
All the symptoms discussed throughout this discussion, I had been experiencing. The Audi continued to sporadically stop or wouldn’t start, to the point I needed to call the RAC. I was told I needed a new battery, RAC where very keen to sale me one at cost of £159. I politely declined and replace it at a much reduced cost from euro parts.
Wrongly thinking I’d cured the problem. The symptoms persisted, with exactly the issues discussed with in this forum.

Cutting to the Case, I bit the bullet and took it to a local VW Audi garage, who ran a diagnostic check and was advised the crankshaft censor needed replacement. £325 later the Audi is back to its trusted and reliable self again.
The only disappointment, is that I too researched the cost of purchasing the crankshaft sensor and found it to be remarkably cheap from Euro parts, and after watching a few YouTube videos, thought it wasn’t outside of my comfort zone to try and fix myself.
So after replacing the glow plugs and battery unnecessarily and parting with a substantial amount of cash, I’m now a happy bunny enjoying the pleasure of owning and driving such a Icon car.
 
I do wonder if there is an issue with connection to - or indeed - a fault with the ecu itself. The instances when other warning lights come are what makes me think this, so agree with others on this. The ecu is a computer after all And they are prone doing odd things when failing. If it is possible to borrow another known good one it would be useful to try and eliminate ( or confirm) by substitution.

I had this on 2 1.4 petrols both times it was the lambda and crank sensor

Afraid to say you cannot blame an ecu for incorrect diagnosis. In this case simply looking at the rev counter whilst cranking and observing it not moving would have been the smoking gun to a failed crank sensor without even needing diagnostic equipment.
The glow plug light flashing is not indicating the glow plugs are faulty its an early EML lamp, infact if like my galaxy you could remove the glow plug wiring plugs altogether and the vehicle would still start and run without fault lights on!
 
The cause on my car was the coil packs. I had isolated and could replicate the problem at will and changing coil packs resolved it.
Thanks for this! I was having this misfire/ engine cut out issue on my 1.4 petrol (BBY) - replacing the coil packs appears to have resolved the issue completely.

Glad my experience helped! The 1.4i is a lovely engine when running well.
