Hi I have a 2010 2.0l Transporter 5 GP. Engine code CAAC. Flashing coil light on, scanned using VCDS and comes up with codes 4911 & 5257 - Exhaust Gas Temperature Sensor; B1 S3 - P242A 00 [036] - Malfunction. I cleared faults and ran for a while then came back. First scan shows sensor 3 (pre DPF) as 1000∞C, (which I think is open circuit). I cleared the codes, started the engine and did a live measure of values, Exhaust gas temperature sensor 3 was showing a value of 113.4 ∞C.

Does it look like sensor 3 is faulty / on its way out? Posted below are the scan and some live data for DPF / EGT sensors etc.

Thanks in advance for any advice / help. Also appreciate any info on how to interpret the state of the DPF soot / ash levels.

From what I've experienced on the CR TDI engines, that is a bad temp sensor.

Are EGT's missassigned in diagnostic stack?
Block values appear different from DTC's.
Make sure you pull electrical connectors and for each sensor to be sure of locations.

Not sure which is sensor #2 as i have read that the location / block is not used on this van and it shows as -0.0 ∞C on the scan.

However, looking at another van with the same problem on sensor #3, there is a reading for sensor #2 so a bit confused ... scan below:

different engine codes in them vans. In tdi pd engines lambda sensor is counted as egt sensor... i mean 1st egt sitting in turbo, 2nd is a lambda, 3rd in top of dpf (below lambda) and 4th in the bottom of dpf. Not all lambdas checking temperature, thats why you have 0 degrees in mvb on sensor number 2.

You need to replace sensor number 3, shows 1000 degrees when fault come on.
