Codes after DPF pressure sensor change

Post by elqwan » Thu Jun 25, 2020 6:57 pm

Hi Guys,

New to the forum here. I need some help with my wife's car. 2016 Tiguan 4motion TDI

The other week a check engine light came on. So I bought a scanner to check out what the code was. I did not have any performance issues despite the check engine light on.

Here is what first came up

Codes:

P245300 - Particulate Filter Pressure Sensor 'A' Circuit - Range Performance
P047400 - Exhaust Pressure Sensor 'A' Circuit Intermittent Erratic

I check to see if the tubes going to the sensor were blocked (all clear) and also checked voltage to the sensor (all good, 5 volts)

I replaced the sensor with a new factory sensor (sensor had an F at the end instead of a G and was made in Malaysia.

I did not do an adaptation as I do not have the equipment and I did read that the new sensors do not need it. I am not sure if that is correct or not.

I cleared the vault codes.

I scanned the car again and a new code came up
P245600 - Particulate Filter Pressure Sensor 'A' Circuit - Intermittent Erratic

I cleared the code thinking maybe the ECU needs to relearn. My wife went for a 40 minute drive and when she got back the MIL was on again but with new codes
P245600 - Particulate Filter Pressure Sensor 'A' Circuit - Intermittent Erratic
P154B00 - Diesel Particle Filter Differential Pressure Sensor - Faulty.
P200200 - Particulate Trap Bank 1 - Efficiency below threshold

So that is where I am at now. Could this be because the new sensor needs to be adapted?

I should also add that on my I/M tests, I have the following still at "not ready"
NMHC Catalyst - Not Ready
NOx Aftertreatment - Not Ready

If you guys have any idea on where I should go to next please let me know.

Thanks

Paul

Hi Paul, I think where you should go next is either to an independent VW specialist or a VW dealer, try to find the former as there are some good people out there who know their stuff and should be much cheaper than a VW dealer, I think you need their expertise with this one.

HI there.

What happened in the end? How did you sort this out?
I'm just about to do a replacement of the same sensor, but plan to do a sensor adaptation using OBD11. Would be interesting to hear what fixed your problem?

thanks
Rob

On most vehicles you need to reprogram the ECU to the new sensor.
This is what I have to do working on ivceco’s and Mercedes. If this is the case you need the dealer to do.

You need a VW specialist assistance, sometimes changing items and they are either not the right spec or they have not been setup on the ICU can lead to other faults showing, it may not be anything more then the replacement sensor you have fitted is making other items show error codes, best bet is to get it checked out.

When you do get this resolved please let us all know how it goes.

Mine was in the VW dealer for this yesterday, I posted here viewtopic.php?f=11&t=7088&start=10

After you have replaced the sensor you must run the adaptation sequence before driving the car otherwise it will not recognise the readings from the new sensor, it will remember the readings from the faulty sensor and use these instead. It may be ok for a short while but very soon you will get the warning on the dash if the correct sequence is not followed as it has no idea how full the DPF is.

It is not ok to just cancel the fault code and continue to do so as you will have expensive DPF issues.

My 2 year VW warranty was out so it was slightly under £200 but well worth it for peace of mind, and if anything goes wrong just take it back as VW offer a 1 year/12,000 mile guarantee on all repairs.

If anyone is interested go to this page and search for G505 sensor http://www.volkspage.net/technik/ssp/ssp/SSP_315.PDF

I replaced the sensor and used obdeleven to do the adaptation of it.

Seems to be working fine...

Standard UK VW warranty is 2 years unlimited mileage. You only get a 3rd year if you have done less than 60k miles, or until you have done 60k miles during that 3rd year in which case the warranty finished as soon as you hit 60k.

In my case on my Tiguans 2nd birthday it had somewhere around 70k on the clock so the warranty finished on that day.

Ah Right. Would an extended warranty not been any good for you? Or did VW ask your average yearly mileage and run for the hills? :lol:
