does anyone know where the fill/check port is on the haldex is? the oil is $30 per/ 175 ml and I'd rather not see any on the garage floor. Please help.

Where is the port to top off the Haldex fluid? How do I check the level and what should it be? I've noticed the case has some oily residue and am concerned going into AWD season. 2003 XC70 60k...

Where is the port to top off the oil in the Haldex? Photos would help greatly.

My CEL has been going on and off, throws code ECM-261a. Found this sensor zip tied by the previous owner, could my search be over? What is the sensor? It sits just in front of the air filter box....

will dial it back half a turn. thanks again JRL

Could the wastegate mod cause a CEL/ throw code ECM-261a?

"volvo code ecm-261a upper limit fault.

according to vadis, potential causes could be the following;

intake air leak
exhaust air leak
low fuel pressure
faulty heat o2 sensor"
Could a K&N...

Thank you Dave and JRL,
Cleaned the sensor and re-fashioned the boot on the haldex and no CEL for now. Didn't think there was a relation between the DEM and tranny but given the complexity of these...

2003 XC70 54k. I purchased the BSR PPC diagnostic tool a couple of weeks ago to clear an SRS code, which it did, because I set it off while taking out the back seat. My CEL went off yesterday after a...

wastegate mod is good and cheap. putting in water/methanor injection system this weekend, will post. ever thought about renting a sports car for the day? tear it up and turn it in as dad used to...

I've got the ones from costco and they work well, I use rainex fluid which seems to help at speed.

My 2003 50K has developed the vibes, at idle it's getting bad. Vibration is present in or out of gear. I have the IPD trans mount and 18 month old round upper motor mount. I'm thinking lower mounts...

I'd hope they're related... that said my, now closed, dealer missed it twice in the past year. If I'm lucky, new pump will solve both issues- time will tell. There is a recall on the pump in the...

2003 XC70 53k, Faint smell of gas in the garage in the AM last couple of weeks. Pulled the back seat and panel under it and to my horror I found gas pooled on top of the fuel pump. Traced the leak to...

I'mvon gas cap #3, Volco OEM. Not it. So, I have to go there. Local dealer quoted $500-600 to drop the tank and replace a sensor, I can live with the CEL for that. I can vacuum test hoses though....

same thing, same year. been living with the CEL. where is the hose?

Vadis indicated a faulty pump in the Haldex. $220 for the part, $60 for the Vadis diag. $30 for Haldex oil. Replaced it myself, AWD works great. Replacing the pump is a pain as you have to remove the...

I've had bad times with both, at least when you get rear ended it's likely not your fault. I fried two nice mavic wheels with the exhaust while on a tray mount, one more thing to watch. A friend...

I've used a tray before, if you're not hauling fancy race bikes they work well and offer a lot in the way of versatility. They're cheaper and easier to store when not in use too. My 2 cents.

I am reasonably sure but will re-check before pulling the oil pump. Which looks fairly easy (compared to pulling the bevel gear -really easy). What kind of oil goes in the Haldex? Same as the diffs?...

i don't know the code that was thrown. I did check the sensor module that gets plugged with snow/dirt in the AOC, is that what you meant JRL? does anybody have a schematic of the Haldex?

1.87 here in KCMO for 87, expect to see cheaper out in the Styx tomorrow.

I just took the # off the receipt from the dealer. Does your copy of VADIS have instructions on replacing the pump?

VADIS reports that the oil pump in my ( 2003 48K) is throwing a fault code and therefore not engaging the rear half of the AWD. Have ordered the pump kit, #30783079-4, and am wondering if anyone has...

bevel gear and splined coupler are fine, shaft turning to rear diff. What could keep the Haldex from engaging? Something about a parking brake sensor? I have checked the sensor in the AOC that gets...
