- In this video I show you how to diagnose a flashing glow spiral dash light fault.
This is for engine code CAYC on all vag models, probably similar solution on similar tdi cr engine from volkswagen.
Using obdeleven I found fault code p242a exhaust gas temperature sensor 3 cylinder bank 1. It can be quit hard to sort out which sensor you should swap out to solve this issue. By disconnecting the sensor(s) you while the scan tool is connected you can determine which one is the faulty.
Always use ceramic anti seize pasta when reassembling.
Nice diagnosis and fix. I have the same engine and scanner and this might come in very handy. Thanks.
P242A - sensor B1 S3 is the brown one, I just switched mine on Golf 6 (in Golf 6 is behind DPF), length is 600 mm. After switching I checked on VCDS and got no errors.
Nice! Well done!
Had you a problem with speed before changing that sensor? Like maximum speed 50/h
Thank you very much for your video, very useful.
Thanks for your feedback
Nice work, maybe useful to show new item part number matches old item part number.
Have the same issue but different sensor. Mines bank 1 sensor 4. Don’t suppose you know where that one is located do you?
No I do not know, you will find it!
Hi i have same problem on my 1.6 audi a1 but have P261C00
P261B00
Coolant Pump 'B' Control Circuit Low
As well come on and go at times. Are they related all together with some wiring issues?
Hello! Not sure, if you have 2 different problems in your electronics it would be worth to thoroughly check all wiring in the engine bay for damage. That problem I have not dealt with yet. But perhaps it is the electric coolant pump wiring?
Hi I like the obd eleven reader can you tell me please is this the free version or do you have to pay monthly to use this cheers in advance. Mark.
Hello Mark, I use the first generation obdeleven pro version, this is a none subscription solution, still use it and is sufficient for me, manual long coding is also working very good with this setup. Unfortunately they "upgraded" to another solution with some functionality taken away at a higher price. Best of luck to you!

Where I can find sensor 4 blank 1
I think you can have a bad exhaust temp sensor without having an engine fault code.
I think so too!
Hi
I know that this is old , but was the car in limp mode before the fix ? I have same code but in panamera 3.0 diesel
No, it was not, but it can be since dpf regeneration is not possible with a faulty sensor.
@@tmdrtn i will check it this coming week , i will do the same reading and check as its the only fault i have in my launch x491 pro
Many thanks
Hi crack! I have same problem, but I switched already the sensor 3 for a new one.. and still have same problem.. what can I do?
Maybe some electric problems?
Hi. I have this error p242a00 on my vw polo 1.6 tdi 75 hp. On my bord is flashing the sensors Incandescent like you on video and the check engine motor. You think i have same problem same sensor like you on this video? And i have the fluctuation on ralanti mode on neutral mode motor up and down turation but not everyday, only sometimes. Help pls.
Hello thank you for watching and subscribing! Yes p242a indicates identical problem, please verify as in video before replacing the sensor. Fluctuations during idle or surging can be caused by several things such as injectors, hpp but likely if there is no fault code I would suspect the egr valve.
Thanks for the reply. I should see the egr valve and after the sensor p242a.
Hi just quick question to use pro you will have to buy credits? Is there you have to pay for every scan and clear codes or just use credit when reprogramming something?, thanks
You can use all functions in pro without buying a single credit. If you code yourself it is for free, the credit system is for using preprogrammed coding changes which you won't need when longcoding, diagnose etc is also free
Hello, thanks for the video I think I have this problem on my Ibiza 1.6TDI. Which software did you use on your phone
Hello! Thank you for watching, I am using obdeleven which is a obd2 dongle with app, very effective and useful tool! I will be posting more material with me using this!
Are them 3 sensors all the same part number and same part as each other.
Hello! No, they are 3 different partnumbers!
Hi mate I've got a seat leon fr 2012 and have a code for P246f exhaust gas temperature sensor circuit range/ performance Bank 1 sensor 4 any idea the location and which sensor needs replacing thanks alot.
Hej, thanks for watching! Love the leon! I am assuming it is a TDI? I think it is the sensor after the dpf. Between dpf and the flexible pipe before the catalytic convertor. But am not 100% sure. That is why I suggest in the video to check with a scantool. Hope this helps you best regards!
@@tmdrtn thanks a lot yh I worried it might be a big problem but when a plugged a diagnostic device to check the engine management light it came up with that code was assuming cuz mine is code 4 and yours is 3 it might be the plug after the plug you took out which was in the middle.
@@tmdrtn and yes mine is a 2.0tdi fr
@@abduljabaar7094 nice, love the Leon FR
@@tmdrtn Yeah 😊
Hi
I have a Skoda octavia 1,6 TDI 1z5 Engine. I have the same Problem with p242a Exhaust Sensor 3 Bank 1
Are you Sure that Sensor 3 is before the DPF with the Brow socket like in your Video? Cause my Car Workshop told me that Sensor 3 ist after the DPF with the Orange socket...Wha do you mean?
Hej, yes it is sensor nr. 3 on the dpf, number 4 is past the dpf. Please check with scan tool what the actual value is by measuring the reL time values, and disconnect each connector at a time to verify a deviating measurement when disconnected to identify correct sensor. Nr 3 should be brown
@@tmdrtn i will change tomorrow the Sensor on the DPF at First...thank you :)

Here you Can See it is correct
Ausgezeichnet!
Hi can you help locate location on Audi a1? Bank 1 sensor 3?
Hej, should be in similar location, is the one on the dpf right next to the turbo!
Located but don’t seem to have the same three plugs on the left hand side, orange, black, brown. Can’t reach in to trace the cable 🤔
Okay, the connectors can be in other location, I do not have that type of car, but it has to be there, your on the right track! What is your engine code ? Is it cayc?
I think it is behind an below the engine somewhere between airfilterbox and engine on the firewall, if you look closely you can see the brown connector
Is this definitely bank 1 sensor 3 mate as I've been told its the one after the dpf?
Hello! Well, what can I say, that's my conclusion and it worked as I show in the end of the video after replacing the sensor. The ones that told you, have they done the job themselves? Is your setup identical as mine?
Yes identical I've got a seat leon mk2 fr 2.0tdi 170bhp and the place i bought it off on ebay said its after the dpf but its worked for you like you say but I can't find any more info online or Haynes manual about the sensors, have you got a link to where you bought your senor please?
This is where it sourced the part m.autodoc.se/ridex/13464840
Hope this helps you!
Hi my plug on the end is black not brown does that make a difference?
@@steeleyg225 hello, yes it probably does, before swapping parts you have to verify your diagnosis
With is the name of your obd diagnostic
OBDeleven
Great video. Although it looks like OBDeleven has changed now and I cannot find the part where you type in temp to bring up the sensor values. Have they removed this feature? Edit. Looks like they have changed live data reading now to channels. And I can’t seem to find which channel I need to look at. Only some of them are labelled as to what they actually are.
Hello and thanks for watching! I have the pro-version. Perhaps thats why you can't use this function? For me the function is available as we speak!
@@tmdrtn mine is next gen pro version. Maybe the difference between android and iOS? If I select live data it asks me to select a numerical channel. 100 seems to be around the dpf but can’t see anything saying exhaust gas sensor
Okej, could be a difference there, make sure to go to live data throughout going to the engine module. Perhaps this helps!
Another option is to figure out which channel you need, you can use allot of vagcom vcds forums and videos because the structure in the cars modules is the same, the only difference is the visual way of presenting it
@@d938 hi im having the same problem as you I can't find that menu either ?
Thanks i have to probleem
You're welcome! Good luck with solving your problem!
and where is bank 2 sensor 3 ??
Bank 2 is the second row of cylinders, you will only find that in a V8,V6 or boxer engine. Not in a 4 cylinders engine which only has 1 bank!
Part number please
Hello, the original vw partnumber is 03L906088AJ, there are various suppliers that offer a similar part which can be identified by using the oen partnumber.
@@tmdrtn Thank you
Hello please Part number audi a6 2.7 tdi Quattro
@@petrkoudelka4406 I am sorry that I cannot help you, please look it up, best is to use vin number a auto parts supplier to get the correct part
