GT Sport TDI - Flashing glow plug and Check engine light - no start

[Spilledprawn]

Hi All, I was hoping to get some community advice on a fault code reading.

Car failed to start after 20 min drive (and then parked for 10 mins), but will turn over.

Dash had ECU light, and flashing glow plug light. I scanned OBDII and got this log

Vehicle Manufacturer: Volkswagen
Vehicle Calibration ID: Not present

Current Fault Log
------------------
P0471: Exhaust Pressure Sensor Range/Performance

Pending Fault Log
------------------
P0642: Unknown code - More information may be available on the web
P0322: Ignition/Distributor Engine Speed Input Circuit No Signal
B2AAA: Unknown code - More information may be available on the web

Historic Fault Log
------------------
ECU reports no historic faults
Other discovered fault codes
(possibly pending, current or manufacturer specific)
----------------------------------------------------
ECU reports no other fault codes logged

End of report.

I'm planning on getting it towed to VW in the morning, but hoping the Exhaust sensor isn't indicative of DPF issues.

Any ideas?

How long have the warning lights been on? Like, before it failed to restart?

Looks like it'll need a DPF pressure sensor, and a Crankshaft position sensor.

Hi Uma, intermittently for 3 weeks. I took it to VW late August and they said it was an oil pressure sensor but not critical. I picked up an OBDII reader after that and noticed the P0471 popping up but car was running fine. The Pending fault log is all new!

DPF pressure sensor needs to be done ASAP. Dealerships should know this. If you don't replace it, you will damage the DPF.

Thanks Umai, I'll get it towed today and hopefully it will be resolved.

Yep this pressure sensor is a finicky part, but the new version VW carry seems more reliable.

Crank angle sensor will complain if car cranks for a bit without reaching the magic 400? rpm, it's probably fine. When my last battery was on the way out and car wouldn't start first go this error would always pop up, now with a new battery has never reappeared.

So you had the oil pressure light coming on for this issue?

Nope, no indication of oil pressure issues, just the CEL and VW mentioned it was the oil pressure sensor. When I got a reader, it came up as an exhaust sensor so I dont know what VW were on about!

Just putting this out there... The dpf sensor won't stop you from starting the car, so chasing that as the cause of your issue is abit wrong. Yes it needs to be addressed, however you may find you have bigger concerns. Engine speed sensors are a common fault on your motor.

Quick update, took it to a specialist here who was unable to diagnose fault, to their credit they didn't charge me for their efforts. They recommended towing to VW! Car is now in their *capable* hands.
