Error code P0488


I have a 2008 Nissan X-Trail 2.0D 173 (T31) which currently has 31k miles on the clock. I made the huge mistake last week and let the wife borrow the car for a few days emoticon only to have it returned with the MIL on the dashboard lit up emoticon

I connected my code reader to the socket and it happily informed me that the error code was P0488 - Exhaust gas recirculation Throttle control circuit A Range/Performance.

In the first instance I cleared the error and drove a further 50 miles and before it reappeared emoticon

Could anyone recommend how to troubleshoot/repair this fault, I know the code is to point you in the general direction but has anyone else had the same issue?

Thanks for such a fantastic forum emoticon

You may need to take the car for a good long drive on a motorway at a highish speed. it may be related to the DPF regeneration a lot of Australian diesel owners are experienceing.
Have a read through the T31 diesel section under DPF regeneration and MIL light.

Steve,

According to the T31 diesel error codes found HERE P0488 related to a clogged EGR valve.

This is not good news indeed, as you maybe experiencing an oil leak that is clogging the EGR valve as described HERE

Please check your air filter and if you notice any traces of engine oil on it, take it immediately to the dealer to trouble-shoot as they might need to replace the oil separator.

P.S. This has nothing to do with your wife's driving style emoticon

Jalalski,

First of all can I say thank you for answering my post, I've been viewing this forum for sometime and you seem to reply to almost every post emoticon

Thanks for the pointer, I can say that since posting the MIL light has now cleared itself but I will certainly check the air filter for traces of oil.

Will keep you posted.

P.s. Please could I blame this on the wife as I hate to part with the X-Trail even for 2 days a week emoticon

Spot on!!

I checked the air filter and as you predicted there are oil traces all over it, I guess I'll be booking this in at a local Nissan dealership in the morning.

Do you know if this is covered under the standard 3 year, 60k miles warranty?

Again, thanks for such a fantastic "Service".

I'll keep the posting updated.

Hi Steve,

It must be covered by warranty. It's a Nissan defect.
