Avensis D4d Problem (53 Plate)

[Paul1234]

the car is now dying on the move

all seems lost, or at least my sanity and bank balance

probably need to torch the lump of *****

thanks for the suggestions

To Paul1234.

Sorry to hear you are having such trouble. Just to confirm your engine code before going any further, it is a 1CD-FTV (belt drive) engine producing 110 bhp exactly the same as my car, two other posting confirm this. Anybody who suggests otherwise is wrong.

This is the point at which some confusion appears to rise, i look after my own car & had the same problem a year or two back. It turned out to be a SCV valve. You need to step back & look at this a fresh, you need to check all inlet hoses from air box to inlet manifold to turbo etc etc.

You must check for any splits in hoses no matter how small, also have a friend rev engine from idle whilst you observe all hoses just incase one is collapsing ie; do the simple things first.

As igormus suggests cleaning tank pick up filter & renewing fuel filter can do know harm either. Make sure your fuel supply lines are in good order, no kinks, acute bends or wet patches. Also make sure your hand primer on top of fuel filter housing is not wet from fuel leaks.

This is my point of confusion, when my car played up, i could not pick up any error codes for love nor money. It was suggested to me that SCV units do not create error ( i will stand corrected on this if anybody know's otherwise) codes? I hate guessing, but broke my own rule & renewed what i was told was a SCV valve. A shiney solid small rectangle metal unit that bolts to front of HP pump ( now rusty) no more problems. Maybe your car has a different HP pump set-up, mine being one of the fist MK11 models, registered in early FEB-2003?

Regards, Beagh.

PS: I too am a bit dissapointed at the lack of responce from the Toyota techs on this one ( i work for other car maker) not Toyota. They (some, not all) are quick enough to trounce upon any incorrect info you may give out on other postings in regards to other faults. But i should qualify that by saying, i have been in this position at work before, it would make you lose your hair trying to find some faults, especially on the electrical side of things. It is also very hard to give an accurate opinion on something that you cannot see or touch. Good luck anyway, Beagh.

the car had real trouble last night cutting out even when moving and not responding to throttle

didn't start ths morning but the AA man managed to get it going by spraying fuel directly into the intake

he believes it's a fueling issue and could be the fuel lines (based on age and mileage) dragging air in (alledgedlly happens on older merc's)

putting it in at another diesel specialist to see what they think

hello Paul

- how did he spray diesel into intake????? was it diesel or eher -- because an ether's flash point is about 30-35 C and it is normallyl used to help at very cold starting in winter.

- have yoou tested both SCVs??? do they work?

- do dyou have comon rail? in case of positive -- check with pressure retaining valve;

- the another fuel issue might be with HP pump delivery valve -----> in case all previous fuel changes have been carried out not carefully -->> small mechanical parts could be passed to the pump and remained under the delivery valve making a dimples on both valve and valve case -- resulting diesel pressure criated by the pump is sharply dropped after the plunger delivery stroke. as the result you can not start youor engine even if both SCVs are in order.

- check visually all fuel pipes both suction and returning lines to the tank.

FIRSTLY CHECK WITH FINE FUEL FILTER CASE ---- it is common problem due to age of the booster diafragm it might to have some micro pores ---- > i hava been using aditional glass primer inline filter for rough mechanical deposits holding + this transpparent filter case shows the diesel level inside ----> when case is not filled in full --> it means there might be an air sucting on the line ----> sometimes the cure of this problem is only changing of fine fuel filter cage with new rubber parts.

specialist has found two failed injectors (not holding pressure/ firing when the shouldn't)

he doesn't think there is a fueling problem but can't be sure

[goodison]

the problem is your fuel pump. it is a euro 4 pump and it does have a scv , the problem is no one has taken notice on the live data of the fuel pressure, it should be between 32 and 38mpa at idle, the scv is none replaceble by a normal toyota outlet. your injectors won't be the problem.looking back on other responses ,apart from the ***** hole comments , parts king establishment has been spot on, hope this helps you

[Paul1234]

this is the problem

the car isn't telling him that there is a problem with fuel pressure on the common rail

he's found an "overfueling" and then tested all four individually to find two failing/ not holding pressure and three glow plugs failed

his view is that if it was a Bosch system it would be the injectors, as its a Denzo system and he has no information about what is happening in the fuel system he is less certain

to get back on the road is going to be expensive and if the fuel system is up the spout as well then it will be more than the car is worth and I will need to scrap it

Stick to Lindop Toyota, they no your car inside out. Have had contact with Lindop in the past in regards to other matters regarding my car, not fueling problems. Used to work for company with a couple of thousand RED VEHICLES, from lorries down to the management pool cars, all TOYOTA ( cars would be one year old when purchased to save public money) AVENSIS. As part of purchasing contract, Toyota would come in & carry out diagnostic checks on any cars within warranty with faults, as we would not have access to such test equipment ( thankfully i now work elsewhere, so please don't consider me as one of those A--/----s who cannot deliver precise comments, sorry your mail, ouch) stick with it, they will resolve your problem.

Regards, Beagh.

PS: Don't despair, your car is not scrap. And is well worth persuing fault, until final fix.
