@Rudi I really do think we have exactly the same problem, my temp sensor has been fitted a week - Friday similar sort of day to usual dropped hubby at work, Daughter at school nipped to the shop came back out and the car wouldn’t start. Called hubby from work he messed with new sensor and it started. Yesterday was a new fresh experience, popped out shopping, car had been at temp for a good 30-40 mins maybe a little longer including driving and on the way back the car went into limp mode and died going round a roundabout - So there I was stuck. Luckily hubby was with me but temp sensor fiddling didn’t solve it straight away, so five minutes or more of sitting patiently on the roundabout and another fiddle with sensor it started. Been out a few times Today less then 5 miles each journey and it’s been fine. I think I officially give up 🤦‍♀️

@Rudi so far so good for me. fingers crossed it works for you

Hi @Rudi I think we have found the problem. We spoke to a local specialist who suggested it could have been the temperature sensor, with the car only failing to start or cutting out when at temperature. The new sensor arrived and has been fitted and since then the car has been running like a dream (not cut out or failed to start once). Fingers crossed the temperature sensor has solved the problem.

@RudiI really do think we are, I think I have also had one cold non start - but 98% of the time the car has been used and has been at temp for a period of time when it has not started. We are unplugging the temp sensor tonight to see what happens - I will let you know how we get on

@Rudi , we have noted that the pump wont always make the noise as its already primed, especially when using the car within quick sucession of each journey. I have however added a new fuel pump and filter, and it does seem to run slightly better - doesnt feel as juddery and the tick over has been better, but we still havent recitifed the issue. The car has not started twice over the weekend, and the fault computer has brought nothing up. The problem seems to be that when the car has reached temperature we are unable to start it until it has cooled down slightly. Or once it reaches temperature, it will just cut out on me. I Only nipped to my local Tesco saturday evening, - came to go back home, and it wouldnt start. Went for another wander round tesco (10 mins) and it started. Only used it twice since, and it started fine, but the car hasnt been up to temperature I have the number for a local VW, Audi, Skoda, Seat speciailist so going to give them a call and see whether they have experience this issue before in any of the VW Group vehicles

@stevenc i havent noticed, but dont think so no - sorry

@Rudi yes keep a listen out, you should hear it prime when you open the driver door. If mine doesnt make a noise or the noise is really faint, I know I am going to struggle starting it - if not that day a few days later. Fingers crossed we figure it out, as I really do like my car apart from this annoying issue

@RudiWell the saga continues, since Saturday the car has failed to start 4 times (the last time being this morning). I had taken the hubby to work, came home and parked up. Twenty minutes later come to start the car to take the daughter to school and the car wont start. I have had to leave it today as I needed to get the daughter to school and me to work - thankfully we have another vehicle (VW T5) so today I am a white van lady lol What we have noticed that when we unlock the car and open the door, we dont always hear the fuel pump priming. When it doesnt prime the car doesnt start - usually starts after 10-15 minutes, today I just didnt have time to wait and see One of the Technicians at work did witness all the non start nonsense the other evening, when I was stuck at work for 15 minutes and thinks it maybe fuel pump - but as the car isnt reading a fault its a complete guessing game. Thankfully work lent me a car for the evening Karoq DSG and I felt a little spoilt Hubby is trying something at the weekend to test whether it is the fuel pump, so will report back.

@Rudi Its all very strange, and baffling as the guys at work cant even figure out the fault. I am now of the opinion that I will just drive it until it gives up completely, as I am not too sure what else to do - as this is the only thing wrong with the car I begrudge getting a new one. Mileage is approx 63500. I will not be beaten on my quest to find the fault, so fingers crossed we can figure it out lol

Mine is doing exactly the same (probably 18 months) , and is now driving me bonkers as it happens weekly - I am starting to blame the new E10 fuel as it has got worse since using this fuel. Over the last few days, the car has developed a new intermittent fault of over revving whilst driving - then appearing to go into limp mode but not actually stalling. The usual problem is the intermittent starting/not starting. It the car doesnt start, I usually have to leave it 10-20 minutes for it to spring back to life (did this last Thursday) - it then tends to give me a week to ten days of trouble free driving, although the last couple of days I have experienced the weird over revving, limp mode feeling whilst driving - if it does cut out whilst driving it has started straight away. You can then throw the enging just cutting out when parked (usually when I am waiting to collect the daughter from school) and after a lot of patience can usually get the car started again. I work at a SKoda garage, so have had the car on the computer on more than one occassion after the above has occurred and the car just isnt bringing up any faults!! We have changed the fuel sensor relay - but now dont know what to try next! Any ideas/feedback would be appreciated.
