P2002 + p0471 + p0473

I've only got a generic tool - I'll be buying a VAG-COM soon!

It looks like my "Exhaust Pressure Sensor" (EPS) is a bit dodgy

But what does P2002 mean - is it something like "Particulate Trap efficiency below threshold"?

Has anyone seen this combination before? Can someone advise what I need to fix?

With the EPS - is this something I can easily change?

BTW I'm on 'holiday' in France - the car seems to be running fine other than the flashing glow plugs and the engine light :)

Cheers

I had the p2002 error, was the EPS. Cost about £138 (i think) to get sorted. Car was running fine before fixing it too, but have noticed a slight increase in mpg since.

Nasty! £138 - was that just for the EPS - or was that with the dealer fitting it too?

You wouldn't by any chance have any part numbers would you?

Good to know that its on;y costing me in extra fuel at the moment - thanks

That was total cost incl fitting. I wouldn't leave it too long tho as it could cause damage to the dpf as the fuelling may be wrong so creating more soot.

I had the engine (emissions) warning light when this happened but not the flashing glow plugs, I thought this combination always put the car in limp mode.

Sorry, no idea of part number, it may be on the invoice, will check when I get back from work.

Thanks again

£138 ties in with it being fitted - I've seen other threads saying the part costs £80.
From what I can make out, the DPF is not particularly easy to access so would take 30-60 minutes to fit hence the extra £58.

This thread identifies the part as a G450:

http://www.seatcupra.net/forums/showthread.php?t=309100

I'm struggling to identify the DPF looking in from the top of the engine so I assume its tucked away at the back of the engine.

This thread suggests there are two pressure sensors:

http://www.seatcupra.net/forums/showthread.php?t=234399

Looks like the DPF is a known problem spot - at least I'm not being singled out.

Looking at this link (and assuming the Audi part is interchangeable) I think number 2 in the picture is the part I seek:

http://www.audi-portal.com/en/diagnostic/sensors_17465.html

Can someone confirm that the part is a G450, that it is the same as the Audi part and that the error codes P0471 and P0473 (and P2002) al relate to this sensor?

Further checking and identifying the part under the bonnet - is it part number 03G906051A ?

Looking at this thread - yes!:
http://www.seatcupra.net/forums/showthread.php?t=282116

Strange about the light coming on soon after a service - this is exactly what happened to me.

Time for a class action? :)

Can I safely change my 03G906051A for a 076906051A?

This link would suggest yes:

"This article has been replaced by the article 076906051A. Please order this item"

Would I need to do anything special to 'recalibrate' this (or any) new sensor?

Ok, so I think I found the sensor - and no way is it hidden or awkward to get to - its just to the left of the engine block as you look at it:

The yellow 'circle' shows its location.
I found a 076906051A on ebay for less than £30
So next weekend I'm going to put it in, clear the fault codes and see what happens

If this all works, £130+ is money for old rope and doubly suspicious if it happens a week after a service (like mine and others did)

I will try to remember to update this thread

I have swapped the sensors and erased the faults but now I get the following:

The MIL is off - but after a short while the DPF light comes on and the glow plugs flash.

If I plug in my OBD II device I get P2002

Do I need to get the VAG-COM up and running?

Do I need to do something else for the P2002?

Cheers

Talking to myself again - more a blog at the moment :)


I'm really struggling at the moment - mentally I was geared up for the new sensor to fix it all.
So any help much appreciated.

Note - changing the Exhaust Pressure sensor has resolved the 0471 and 0473 - I'm just left with the P2002....

I found this thread (for a Leon):
http://www.seatcupra.net/forums/showthread.php?p=3300165

This says that P2002 = "Particulate Trap Efficiency Below Threshold"
And that this typically occurs around the 110k miles mark.
My Ibiza has only done 56k miles - is this a bit early to see this problem?

The thread goes on to say that a new DPF is over £1k :cry:
The car is only just out of warranty - any idea how likely it is that Seat will foot the bill for this?

Then the thread suggests its possible to jet wash the DPF back to health
Has anyone really done this? Or is this just a friend of a friend stuff?

Lastly, it says that the garage did a forced regen.
My Ibiza had a forced regen two weeks ago, then did 600+ miles of French motorways (80mph), then I drove it for 40 minutes at 2k revs, last weekend it did the return 600+ miles and today it did another 200 miles of UK motorway driving (70mph of course!)
Is it really likely to need a regen?

I'm thinking not - but it sounds like the sensor is shot - so my last question (hopefully not to myself) is can the DPF sensor be fixed separately - or is it the whole thing?

The P2002 grew to include a P242F which means that the particulate filter was >90% full

I took it to a dealer who commiserated with me and explained the future and how it would affect my wallet:

£400 for them to take the DPF out, clean it and replace
£800+VAT+Labour to replace the DPF

I took a punt and went for the clean and I'm glad to say it worked.

That said, I very much doubt I'll be keeping the Ibiza - in this adventure I discovered that Seat's idea of customer support is non existant and that the DPF _will_ fail at some point at which point it will cost >10% of the value of the car to replace it!

Time to get rid of the Car!

For the record the sequence of events were
MIL came on due to a broken exhaust pressure sensor.
Took to dealer that forced a regen - but they could not supply sensor (none in stock)
Told to ignore warning light and carry on driving.
Drove >2k miles at european motorway speeds (ie fast enough and long enough for passive regens)
Flashing glow plug lights came on - rang dealer - they said ignore unless limp mode engaged
Drove >500 miles of UK motorway (still fast enough for a passive regen)
DPF light came on and then limp mode
Took to dealership and ended up as described above.

I suspect that with the exhaust pressure sensor broken, the ECU never did a passive regen and even though I was going fast enough for that to happen it never did.
As a result, the soot continued to build up until it was >90% blocked.

I think the moral of the story is:

DO NOT IGNORE A BROKEN EXHAUST PRESSURE SENSOR FAILURE.
Fix it ASAP - do it yourself - £26 from ebay its easily accesible to the left of the engine
(you do need a torx bit - but hey treat yourself to a set of them!!)
Do not let the dealership charge you >£100 for this!

Probably a bit late in the day to be replying to this thread but....i think the dealers ripped you a new asshole.
My fault code developed into P242f so i took it to a specialist expecting the worst as detailed above.
Turns out the DPF was 45% blocked and a forced re-gen was possible.
Car is back to itself now with no more warning lights on

Yeah! You're probably right. I'm sure all the stealership are in it for the money and not the customer service.
That said though the car had gone into limp mode (well the turbo wasn't engaging) and my dashboard was lit up like a christmas tree and if it was over 90% blocked the dealersoftware would not allow a forced regen.
Then the only recourse would be to clean our replace the DPF. Since that takes a couple of hours to take it off and a couple more hours to put out back the price at dealership hourly rates brings it to the ar$e ripping price :-(
On the whole I think you were lucky - you caught it at 45% and the regen was an option. I wish I'd taken mine to the dealer sooner.
