Engine Cutting Out

How far have you driven it since the last failure? same roads, conditions etc?

Same roads. No change there. Maybe only done 150 - 200 miles so far since the last Engine Cut Out.

Normal had become once per 20 mile commute.

Will update.
 
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 . . . . . . . .
 
Ok it is official. The crankshaft sensor has fixed the issue. When the sensor was removed the car immediately exhibited all the same issues on startup with all the warnings appearing and no rev counter. New sensor all fixed. Unfortunately this will mean this lovely car will be up for sale soon. If anyone wants a nicely specced 1.4 Sport in cobalt Blue with 77k miles the advert will be up soon

Are you saying that, like me, you have also fitted a new Crankshaft Speed Sensor and that has fixed your fault ?

Only question now then is why did scanning not diagnose that as the fault ?
 
Yes. That is it exactly. When the crankshaft sensor that I had was removed and the car started it would exhibit all the same failures immediately that it did when it stalled occasionally. New sensor and all problems gone.

BAD NEWS ! For me anyway.

Went out in the A2 today. ENGINE CUT OUT. Exactly the same as before. The one where the Engine actually has stopped but re starts instantly.
 
So far !

Hope it is fixed for you, of course.

Think I should stick to my '66 Beetle and '72 Type 3 Automatic Variant. At least I can understand anything that goes wrong with them, and fix it myself !
 
Latest Update. Went out in the A2 on Monday. It was back to the equal worst it has ever been. Engine Cutting Out all the time. I had a theory that maybe it only started doing it again as the Fuel Level went down. It was full when the New Crankshaft Speed Sensor was fitted and had been running down since. Filled it to the brim. Made no difference whatsoever.

Latest advice I got on Tuesday was that the fault would be the Camshaft Sensor, and that both Sensors Crankshaft and Camshaft should have been changed at the same time.

Is there anything in that please ?

Went for MOT Test Tuesday afternoon. Passed of course. Emissions were not as good as they could have been but within Pass limits. Seems the insides of the CAT have come loose Driving through the floods.

Anyway I cleaned up and greased the Earth Connection on top of the Cam Box, disconnected and cleaned the Plug for the Camshaft Sensor. Wednesday morning drove to work no problem. Thought it was fixed at last ! Wednesday night driving home there was no problem, until about 1 mile from home. Then it Cut Out again.

Yesterday ( Thursday ) same commute to work and back. No problem. Did not Cut Out at all ! What is it ? Do I change the Camshaft Sensor ?

Is there any point fitting a new more expensive Camshaft Sensor ? Euro Car Parts have a 30% Off Everything Discount Code at the moment. Makes a HAAS Sensor only £20.99 Their alternative is a BOUGICORD one at £32.89 with the 30% Discount applied.

New HAAS Camshaft Sensor arrived today, so fitted it thus evening ( 2 minutes, or less of a job ).

Not had the road test yet. Catalytic Converter and Middle Exhaust has failed. New one going on tomorrow £215 fitted. Could buy one a lot cheaper but not got the facilities to fit it myself.

Whoever it was said try carparts4less for the Camshaft Sensor, because they were part of eurocarparts but cheaper was correct. They would have been cheaper for the same HAAS Camshaft Sensor £18.90 delivered free !
 
Bad News again already. Fitted the Camshaft Sensor yesterday evening. Drove A2 to have £215 Catalytic Converter and Middle Exhaust fitted first thing this morning on my way to work. No problem all the way there. Picked A2 up late afternoon. All quiet and driving very nicely.

ENGINE CUT OUT on the way home with approx 32 Miles driven on the new Camshaft Sensor, so if anyone wants a good used Crankshaft Sensor, or Camshaft Sensor, or new Catalytic Converter and Centre Exhaust from an A2 that had been scrapped . . . . . . . .

Did you check the fuel cap? Is it tight / can you replace it with a new one? Air in the system would appear to be reasonable....someone *must* also check the earths at the base of the A pillars on both sides. I would also want to check the connections to the back of the instrument binnacle, which is four screws in total.

Hi Bret. I've certainly done those things but not checked the dash connections? Is this a known issue?
 
no, but the various error messages (different lights) indicate there's something going on with the cluster itself. I would take it out - two screws from the inside, tx20s, I believe, then the three on the support for the cowl... it's not many but you'll need to pull the cover of the steering wheel mech off (the cover covers the screws at the base of the cluster, it pulls off towards you). Do NOT try to turn the ignition on when you have no cluster connected. Check all cabling is in good condition, disconnect and reconnect the blue and green connectors, check that routing makes sense.
The earth connections for everything are at the base of the a pillar, so if they are loose (which is eminently possible) you'll have wierd behaviour. Check the plus connection in the secret compartment, too (but disconnect the battery before doing that one, please!).

I would also replace a battery if it's ever been deep discharged or is anything less than 5 years old. There have been (rare) stories of very strange behaviour with insufficient voltage in the car's systems.

Thanks Bret. I'd checked the battery and it had a new alternator at some point before my ownership. Voltages are a bit low so will replace the alternator and see how I go. I will keep you updated if this is OK?

Can I ask what the secret compartment is?
