Coil light

My 1.6tdi 2014 coil light has been coming on after about 10 mins of driving when the engine isn't at running temperature. When I come to a halt and go into neutral a warning appears saying stop start fault and then the yellow engine management light appears and the car goes into a limp home mode. After leaving the car standing over night I started it, no lights appeared and took it to the local garage who plugged it in. There was no faults on the reader. I have noticed now that the stop start is now permanently disabled. Anyone had anything like this before? Cheers guys and gals.

Hello David,

Thanks for being in touch with the forum. 

Looking at the age of your car, and taking note of the symptoms, I would first be wanting to eliminate the battery as the source of your issues - but it wouldn’t surprise me that it is the culprit. 

Do you know if the car is still running on its original battery? 

If it were mine, I would be taking it for an ‘essential journey’ of at least 10 miles, then getting the battery efficiency checked - Hartfords were/are doing this - although 2 points:- I’ve known batteries to pass the old ‘drop test’, but still be sub standard in terms of cold cranking limits etc. Also, if the battery is found to be at fault, what replacement do you buy? For me, it has to be Varta/Bosch ( generally the OE supplier’s), and I buy from specialist on- line suppliers such as Battery Megastore, Tanya etc. and I only buy the grade which has a minimum of a 4 year warranty. Look on suppliers  EBay sites, where you normally get free delivery. Oder direct from them, and you generally don’t! Why?? 

Perhaps you could let us know how you get on. 

Kind regards,

Gareth.

Thank you for this! New varta battery on order and will be with me tomorrow. Its the original battery so I'm changing it. Had a good run in it today and all was fine apart from the stop start not working. No dash lights on, but a warning message saying stop start is not working. Also had it on a obd reader and no codes were on it. So hopefully the new battery will sort it. Thanks again Gareth!
