Hi, I have ownen my EOS for 11 months and in that time the car has refused to start ( engine just turns over when keyinserted but doesnt start) 12 times. I have had the car back to VW twice last time they replaced the starter mootor saying this was the problem but last night AGAIN it refused to start
I have to wait up to an hour and then the car eventually seems to start. Its not a heat problem

Has any one else had a similar experience please
thanks
Milton

Never had this issue, but I have a two questions. Answer honestly and they may lead you to a possible cause.
Question 1: Do you let your vehicle run for a little bit after arriving at your destination?
Question 2: Do you ever take very short trips, and the engine does not warm to 190° on the temp guage?
Reason for questions:
1. Turbo engines need to cool down the turbo after running. Does not take too long, I usually go about 30 seconds to 1 minute. Letting the engine idol also lowers the fuel supply to the jets. Too much fuel left in the supply from turning off right away can foul the plugs when you go to start.
2. Turbo engines need to warm completely to running temperature or you can foul the plugs. My guess would be that you have short trips that do not get the engine to full temp, and the plugs are fouling. Dealers should tell you this when you buy a turbo engine, however I wonder if they even realize it. I have watched a dealer pull a vehicle around to the customer and turn it off right away. You can get by with this quite a few time, but eventually the pluggs will start to foul. See if these scenarios fit, otherwise not sure.
Hope this helps,

I made a mistake. I stated the temp for petrol engine. TDI will have a different normal operation temp for diesel. I do not have the normal operation temp you should see. Next time you are running take a look after you have driven for about 10 -15 minutes it should top out. That will be your operational temp. Always try to ensure your engine gets to this temprature before turning off.

When cold, my Eos always starts the instant the key is turned.

In maybe the last 6 months, it is noticeable that it takes longer to restart, after it has been driven at normal operating temperature.

The other night, after filling up with fuel, it just wouldn't start. It turned over happily, but just wouldn't kick.

Rang for road side service, he checked all the fuses, tried all his usual stuff, and still nothing. Eventually, he disconnected the battery and reconnected it and it started, and has been starting when cold without a problem since.

The hesistation when warm seems a little less as well.

Geoff, how long has it been since the fuel filter was changed? I had a similar problem with my old-fashioned mechanically injected Toyota diesel. The filter housing partially filled with crud from a batch of dirty diesel which swirled around and intermittently block the filter when the engine was turned off. A few taps on the filter housing would usually dislodge enough crud to get the beast started. Only problem was the filter eventually clogged completely before I could get home resulting in a roadside filter change and injector pump reprime [I always carry spare filters and fan belts as these situations always happen off-road in areas with no mobile phone coverage ].

I suspect you have encountered a load of dirty fuel in your travels - if the filter is found to be full of crud, I would change the next two filters early as they will have to remove the remaining crud that is still in the fuel tank.
