Egr Valve Replacement

[jammyjamie3]

My Toyota Avensis 2.0 D4D 2004, once the engine warms up loses power and struggles to get up hills. When foot is flat on floor takes ages to get going before turbo kicks in, also get black smoke from exhaust. I had the EGR valve cleaned by local garage but it has not fixed the problem. No warning lights on dash and computer plugged in and there is no error codes showing. Do you think it is best to just replace the EGR valve and if so would you go for a second hand one due to cost of a new one been around £275. Also can someone suggested cheapest place to buy one new or second hand.

hi mate

before giving you an advice I'd ask to confirm an EGR stem inside slides well -- in other words the unit as whole is operative. even though they ve cleaned it they had to confirm the flap inside is well shifted. be sure the EGR is only unit serving and responsible for emission control.

Please initially check with the below listed:

- condition of fuel filter;

- total milage on the clock ---please state

- condition of an engine filterl

- remove suction rubber hose from turbo -- just undo and manually rotate the shaft -- at the same time feel how easy the shaft is rotated; its play on axis/radially to evaluate the gaps.

- check with movement of link of vacuum attachment on the turbo;

- release variable vanes on the turbo to evaluate their rotation between polar end points --> if you feel some obstacles braking movement then the outcome is turbo is partly blocked by carbon;

do not buy anything unless you check with the above.

safe your pocket so far matey

Hi

Sorry of rate reply I have only just seen your response. The Milage is 71,000 The fuel filter is about 6 months old new air filter and oil change in last 4,000 miles 3 months.

I have not checked the turbo pipe yet but will try.

I took it to another garage who thought it could be a engine sensor and thought it may not be an egg valve. I have booked it in with a specialist diesel injection centre but thats not for another week. However the problem seemed to corrected it self and the car is fine now. Will it go again do you think.

I had the same problem this week with my 2.2

i was just going along nicely when i lost all power then the vsc and traction control off light came on....also when i tried to accelerate there was heavy black smoke

I checked for a fault with my code reader and P0400 came up ...EGR malfunction

I checked the if EGR was blocked ...although i had only cleaned it a month ago

I contacted my mechanic with a view to getting the car to him

but within 10mins and switching the ignition on and off a couple of times... the warning lights on the dash went off

now the car is back to normal and in fact it seems a bit more lively...perhaps its cleaned something out......Im definatly a bit confused as to what happened but at least its cleared its self

hello

where is the egr valve located on a 2004 d4d avensis 2.0 and is it hard to clean.

[Phil01]

P0400 is infact EGR flow, the ecm has detected that the egr valve has either stuck open or not opened at all, the engine ecu detects the difference of airflow across the MAF sensor in relation to the egr operation, if the GPS (grams per second) air flow does not alter it will throw an orange EML (engine malfunction light)

IMPORTANT,,when you clean the egr valve dont pay too much attention to the actual cleanliness of the valve but pay attention to the valve shaft for free up and down movement,,it must must must move freely.

I give mine an "Italian Tune up" once a week. 70mph in 3rd gear up the M1 for about 3 miles. That seems to keep the EGR flowing ;)
