High Emissions Service Required - Fixed

MisterWooley · Jul 27th, 2018, 19:28

Hi all, This message popped up on my XC90 2004 D5 last week. It was accompanied by constant limp mode. All usual methods of clearing message/fault even as temporary measure failed.

I post here the update of the fix in the hope that it might help another volvo owner with similar problem.

First step to run a scan with Vida, not a great deal of help a whole bunch of codes typically signal too high/too low/out of range. Some research here suggested that all components affected were on the same fuse, No 11 in the engine fuse box. So I pulled no 11 and it was blown. Replacing it blew another immediately. I started disconnecting those components that I could easily identify but fuse kept blowing.

Time pressure and the need for XC 90 to be usable and ready dictated that I pop it round to my local indy, Sheffield & Meredith (Leicester). got it back today fixed. Apparently a broken wire shorting out fuse 11. Something to do with crankcase breather, maybe the feed to the heater nipple. Not a common problem they said, maybe damaged by previous work on the car. Not while I've been owner but I have no previous history.

Anyway, good job from the indy. Now up and running again.

Was it just a cable problem? No parts had to be replaced? It's quite an old post, but I'll see if I can get an answer.

That was a while ago!! The fault was at a connector. The connector was reconnected, that’s all

Sry, my english is not the best. Which connector was reconnected? I have this problem too. Fuse 11 blown, I changed it for 3 times. Car has no torque and A/C doesnt work.

I got these codes: (translated from hungary to english)
6000 - AC RELAY, SIGNAL NOT PROBABLE - PERMANENT
4400 - EGR VALVE; VALUE NOT PROBABLE - CONSTANT
6600 - BAD GLOW PLUG RELAY - PERMANENT
6700 - ELECTRO-HYDRAULIC MOTOR STRUCTURE FAULTY SIGNAL - PERMANENT 6800 - ADJUSTABLE VALVE TURBOCHARGER REGULATOR FAULTY SIGNAL - PERMANENT

I’m sorry, I can’t remember and I have now sold my XC90 so I can’t check.
My suggestion is to try following the VIDA diagnostics. For each of the codes it will give you things to check.
I would take one of the codes and just follow all the diagnostics. The other approach would be to examine the wiring diagram and see what fuse 11 feeds?
