Flashing glow plug/limp mode/Error code P164B00

[Liamgelder1]

Hi,
I’ve recently ran into a problem with my seat Leon mk3 2.0 tdi 184(Has 35k miles on clock)
Within the time from starting my car from cold to the engine getting up to temp it sometimes goes into limp mode and disables cruise control then also displays a flashing glow plug light. As soon as I pull over and turn the engine off and then back on again it disappears and then proceeds to run normally. If and when the engine does get up to temp it’s fine and it won’t happen and drives perfectly. I’ve plugged in my OBD11 to see the error code and it comes up with the P164B00 oil pressure switch fault.
Everytime I now get into the car I can’t enjoy my journey without stressing until it gets up to temp lol.

Any help on this would be greatly appreciated

Have you tried the search function?

P164B00 and flashing glow plug - limp mode on FR184 TDi

Hi Folks, About 6 weeks ago, when the engine is cold, soon after setting off and at about 45 mph/1600 rpm the car would go into limp mode with flashing glow plug lamp. Switching off and then back on cleared the problem and car ran fine with no problem for a few days. I connected my ODB Eleven...

On the Seatcupra.net webpage it's at the top right. @SuperV8 has also linked the result to save you searching.

I had this with my diesel Skoda Yeti a few years back. It turned out to be a clogged DPF.

I then purchased the VAG DPF app and a bluetooth OBD dongle, which allows me to monitor the DPF and when it gets to around 98% full run it until it regenerates and have never had the problem since.

Why car manufactures don't include DPF status on the dashboard is beyond me. All it would take is a simple red, amber, green display and instructions to keep running the car once it goes red until the car has regenerated.
