Hi thanks for the reply. I think that I may have only used the horn a couple of times before this happened. strangely, it happened yesterday, but this time it didn’t give any dash warning lights. Also Carista didn’t show any fault. This time I was at traffic lights and it took nearly 5 mins before the engine eventually started. i am due a service and mot in the next month so I’ll get the garage to have a look as they have VCDS.

Hi i ended up changing the battery. no change.

Hi I’ll put it on charge tonight, just to see if it makes a difference but I’ll probably change it anyway as it’s a few years old and I don’t know the history as I’ve only had the car since September

Hi It’s a 2014 L&K TDI 170. I haven’t changed my profile since I changed cars. when you say coded, could you explain? I’ve heard it mentioned before, but never known what that does. with past cars I’ve just changed the battery

Hi TruckbusUK Just checked the date on the battery. It’s Aug 2017 so I’ll definitely change it.

Hi Paul52 I think that I will replace the battery as i have no reference of how old it is. As you say it has no starting issues, but it can’t hurt as it’s not 100% healthy.

Hi Austin7 Thanks for the detailed info. When I get time I’ll take a look. It maybe nothing, but looking through the small amount of paperwork that came with the car I noticed that a clock spring had been replaced at some point. Again, thanks for the help

Hi yes it sounds normal (twin tone)

Hi KiNeL The reason I asked the question was that sounding the horn was the only thing that caused the engine to stall. I’ve never had any issues with starting when the headlights are on auto and the HVAC is also on. I checked the battery and it was reading 12.18V. Obviously this is not ideal, but as far as I was aware, nowhere near problematic.

Let’s see if I am able to charge her for the new battery

Wise words! I only used the horn because I was picking my mother in law up. I blame her

Hi, thanks for the reply. I was thinking that may be the case.

Hi. I’ve got a strange one for you all. When the engine is idling and the horn is sounded, the engine stalls. Upon restarting it judders and stalls again. It takes several restarts to get it running again. I’ve scanned with Carista. Sometimes it shows a fault with fuel rail pressure sensor, other times it doesn’t register a fault. 2014 L&K to 170 Any ideas? Cheers Dunk

Hi Ive not tried that. I’ll do it first thing tomorrow morning cheers

Hi yes, the screen shows the boot open and closed when the boot is open and closed, so I’d assumed that the sensor in the lock was working okay.
