Leon 2013 cutting out whilst driving

[kcat81]

Hoping someone can help me as several mechanics have been tried with no answers.

I've got a seat leon Se copa 2013 which cuts out whilst driving. Usually it won't start again for a good while, but eventually has each time.

No error codes show on the diagnostics and there are no obvious reasons for this such as battery etc.

When it cuts out there's no juddering and the dash lights stay on. When trying to turn it on it turns but doesn't ignite fully.

I've been told it could be a dry joint on a system relay but can't identify which relay it would be. (My mechanical knowledge is limited, this is what I've been told).

Has anyone had a similar issue that could shed some light please?

Also, it's just been mot'd and whilst I've had to fork out for an exhaust, caliper and spring repair no other faults were found

No error codes? Strange. Did the garage do diagnostics with vcds?

They said they ran all diagnostics and nothing was coming up so they couldn't confirm what the problem was.

I'd get a second opinion.

Also check the obvious battery terminals are tight, plug leads are tight etc.

Borrow obd eleven or vcds and check for codes yourself, then post results here

Which engine?

What sort of speed when it cuts out?

 

[kcat81]

I bought a diagnostic kit and the following codes are showing. None of these strike me as causing the cut out.

Can network gateway
01334 door control module rear right j398

Heating and ac
13701536

Central electronics
00924 headlamp wash/wipe
01334 door control module rear right j398
03266 control circuit for relay klaxon

Drivers door

Does it do it every time. Does car cut out and come to a stop and have to be restarted. Can you drive over 30mph at all. If its just an interminten fault and you can still drive the car most of the time it might be worth trying coil packs, if all the basics like the alternator is working and the battery is charging etc etc.

No, it does it very sporadically it would seem, there's no obvious reason as to why it does it sometimes but not others. I drive over 30mph often. Battery tested and Is fine.

Hi wondering if you got a solution mines doing the exact same thing

 

[kcat81]

Hi, I initially saw a slight improvement using redex - it cut out less often, so I had the fuel filters, injectors and spark plugs replaced. It cut out once about a week after that, but hasn't since (approx. 5 months). I would look at the fuel system for sure.

I was thinking getting the crankshaft sensor replaced or at least checked, did you have a look at that?
