Technical problems with EGR system (error codes P0657-17, P1304-62, P24A4-68)

What worries me is that it is not sure whether cleaning the DPF and the LP-EGR cooler will be sufficient in the long term. I will keep you posted, regards Bert

Just cleaning the LPEGR cooler will work for a period (current experiance says its variable and could be 1 to 2 years). but it will eventualy block the cooler because the DPF is still cracked. Try to get a 2 year warrenty on the fix. Monitor every decent journey with multiecuscan, if required i will come up with the simplest method to monitor.
At least its better than being told to go away.

@theoneandonly: that is a good advice ! I will ask about this warranty time .
The first thing i will do when we get the van back is to connect the MES software and check for errors and changes in parameters. Next we will go for a 500 km long drive to see if any regen happens and monitor the F4 parameters you gave us.
The lawyer advised us to get an independent 2nd opinion incl. written report to have a prove of the status of the exhaust system. For this i want to go to a Fiat garage let them do a check.
If there any developments i will post them here. Regards Bert

@theoneandonly : when i let fiat do the 2nd opinion check i could point the cracked DPF out to them. What can i tell them to do for a check ?

This should determine you have a cracked DPF
