P04d900

[cwmitch]

Hi all the check engine light came on my 2014 D4 118k about a week ago, The error code is as above. P04D900 I popped into my local dealer, To be told Volvo have washed there hands of the issues re Valve and or Cooler.. Is this right or have I just been hit with an £800 bill to have the cooler changed?


Many thanks in advance.

Yes that code relates to an EGR cooler with restricted flow ( sooted up) you might get it off and try and clean it out with acetone?? has it had a new cooler before ?

Maybe try another main dealer or show the following thread to you local dealer: D4 VEA 'check engine' light / EGR fault thread

I've no idea if it's had a cooler before, I got a printout on the history whilst under warranty up to 80k but it's not that detailed and just regular services/histroy since then. Now on 118K.


Thanks for the reply

If you do get a NEW EGR cooler it will be a modified type with larger passages.
Make sure you have the latest engine ECU software too!

Many thanks I did notice the new one has much larger passages than the original one, I did notice that the lower bank of passages were much worse than the upper set. I'll post some pictures tomorrow.


Once again many thanks for the info.

Black and soot looking to me but I didn't scrape them to see.

Hears some pictures annoyingly I can't find the pic of the old cooler!
The EGR wasn't to bad either cleaned before or replaced?
