Exhaust pressure sensor fault!

Featured Replies

As ye know I had my injectors replaced yesterday under recall and a service and then today when I started it I had engine light on,I brought it back and they said its showing a fault of the exhaust pressure sensor which is something to do with dpf , not sure if this has anything to do with injector replacement although they told me the first fault for this came up at 92k and now there's nearly 95500 km now,I got a new sensor off a friend but the garage can't code it or configure it till Friday ,They said not to drive short journeys as my car is not regene ing with the sensor not working.

Can I not just fit the new sensor or does this have to be coded in by a dealer?its the sensor located beside the timing belt cover at the top!

The car is a 2007 vrs tdi .

Hi,

Sensor does need coding after fitting

Thanks, will the part number I have above work or is there a new modified type out ? Maybe someone knows part numbers!

I think the part number should be 076906051A, this is whats listed for 2007 cars with engine codes, BLS,BMM, BMN.

Thanks tony, the part I have is 059 906 051A so I take it this won't work and I'll need to buy an other!

Hi,

Better to fit correct part number, but as said before sensor needs adaption carried out once fitted. also needs handling with care during fitting, contains very sensitive membrane.

Iv just checked my sensor in the car and it has sensor with part number 03G906051A some I take it this is the older type! If I get the garage to fit the new sensor does it need some sort of a remap done that was a recall at some stage?

That part number was dropped on the 01/07 and updated to the part number I gave you in previos post, once fitted it requires adaption, which is calibrating to the car with a computer. A forced regen of the DPF is normaly done at the same time.

Ok guys the closest time I can get this done is next Tuesday ,they need to fit the new sensor and do a forced regen,they have me freaked out tho telling me I can't drive the car because I could damage the dpf filter which in turn will cost me €1200 to replace,

Is this true as I need the car to drive to work from now till Sunday!?

i have to agree with the garage it could damage the DPF

Tony

Yes it if can't regenerate and gets over 90% saturation the DPF is then scrap.

So what's my options then or leave it parked? My daily commutes are 30 miles

Hi

Sorry to jump in but I changed this sensor last week at home on the driveway brought the part (076 906 051 A) from Skoda dealer no mention of calibration car runs fine now with no fault light or regen light anymore.

I'm not a mechanic, Should I get in calibrated by Skoda?

Was ur engine light on or what made u change it?

Although the sensor maybe working the car does not know how full the DPF is, the Exhaust pressure sensor needs to have an adaption cycle run or the DPF will either not regenerate or will regenerate incompletely. See my DIY thread in the Superb MK2 forum which shows how to complete this on a MK2 Superb PD140 using VCDS.

http://briskoda.net/forums/topic/222633-g450-sensor-adaption-using-vcds/

Part way down is the required VCDS coding, confirmed on a number of forums that without adaption you'll run into DPF problems.

The engine management light came on when I turned the ignition on but before I started the engine. I only do a 12 mile journey to work on B roads and through villages so my dpf regen light came on every two to three days. a good run down an A road soon fix the regen light. I called my local Skoda dealer quoted the fault code and they supplied the wright sensor which I fitted.

From what I can tell the sensor detects the pressure difference around the dpf so there should be no difference when the engine is not running. If there is more than 65 to 70mbar difference the management kicks up a fault.

So when u fitted the new sensor did ur engine light go out ?

I replaced the sensor, cleared the fault code, but did not start the engine until the adaption process was complete, then the light went out once started and the car drove perfectly afterwards.

Basically when the sensor was broken the DPF will continue to clog, but the car has no idea whats going on inside the DPF since the sensor is feeding the ECU either no data at all or rubbish. When you replace the sensor the car assumes, now that the sensor is working again that all is as it was before the sensor failed. Result is that the DPF is, in reality more clogged and therefore more likely to fail totally as it will be to full before the regen is started. You must complete the adaption, as this will cause the car to effectively forget everything and relearn from scratch what the DPF levels are based on feedback from various sensors.

Thankyou mannyo

I will get it sorted ASAP.

The light reset on a handheld unit.

And that is the only way to replace the sensor

The light will reset, but will come back on again. only this time the DPF maybe full, but the car will not know this and assume the sensor is faulty again, only this time the DPF will require replacement and at current price its around £1K to replace as its considered a serviceable part.

But has this actually happened that people had to replace the dpf filter? I'm sure there had been cases where people kept driving with the sensor faulty!

I know a lad with a vag computer will this be a straight forward procedure for him to code it in?

Can I fit the sensor and then drive to his house to get it coded in?

My sensor on diesel vrs had to be changed at the back end of october lasr year. due to the miles on the car and dealer serviced skoda paid for half the parts cost as a good will, as they said it was a common fault. According to a audi master tech if this happens on a audi they replace the sensor, loom and have to re-pin the plug at the ecu.
