Avensis 2.0 D4d Cold Starting Problem

[bornagain]

Hi,

I have a 2008 (old model) 2.0 d4d Avensis (23,000 miles)

For the last couple of weeks, it has been tricky to start from cold; the engine fires immediately then almost immediately it won't rev and dies away. Try again 2-4 times and then it runs perfectly.

Based on comments on this forum I suspected a blocked EGR but as its still under warranty I have taken it in to the dealers, they kept it overnight to try a cold start and are telling me that it needs a new set of injectors as they are "not holding pressure" I asked if there was a problem with the EGR but they say there isn't.

I questioned them and pushed for more info but was met with the expected "they (the mechanics) are the experts sir"

On the face of it it doesn't really matter to me what the problem is, so long as they fix it under warranty -which they are going to do; my concern is that if I need a new set of injectors after 23,000 miles and 23 months of age, what is the long term reliability (and cost) of the car going to be when it runs out of warranty in 13 months time ?

Any opinions ? are they making sense with their explantion of the injectors not holding pressure, or is the garage just looking to milk Toyota for a big warrantly claim ?

Thanks for reading

Its like asking how long is a peice of string that question to be honest,,,, just pot luck really ,,, my injectors went on my 2.2 06 d4d at 40,000 miles and then my head gasket went at 46.000 miles !!! all done under warranty thank god ,,, Toyota have finaly admitted that there is a common fault with the head gasket on the 2.2 ,, i took quite a bashing on this forum to be honest because i knew the problem was rife but was told otherwise! ,,, all my new work has been given a one year warranty or 100,000 miles ,,,,, my car currently has 110,000 miles on it !! only at 106,000 miles has it started to give me problems ,, wont start in the mornings somtimes ,,, changed filters and plugs etc but to no avail ,,,the old old shape avensis are the best would run forever ,, these new brand of cars are !Removed! parts built in UK ,,, im Taxi Driver and have had from 60k to 105 k trouble free so thats not so bad ,,, cars break down after the warranty goes if you have no confidence in the car just get rid ,,, cost wise at the moment you couldent give a toyota away !!!would i buy a toyota again ?????????? lets see.......... NO

hi mate

the lifetime of the injector depends on what "diesel" it injects. The wrorse diesel the more problems leading to the common railed pressure dropping fastness. So re injector -- it normally has needle valve (needle + seat) -- the needle contacts the seat in a thin circle line to have good sealing under spring pressure. Ok when the needle moves up/down by means of solenoid coil and loading returniing spring -- it kicks this seat and that espands this contact circle. So the more contact surface the less contact pressure (depending on the spot of contact). In case this contactting pressure has become less, but the HP pump does not ask -- " whether needle valve is in order" - -it continue to deliver diesel and criate constand pressure in the rail. And this leeds to diesel pouring into the cylinderss giving no chance to ignit this jet. The normal injection lasts fastly with respective sharp sound + diesl fog. The diesel fog is ignited easily using glow plug than to ignit jet of diiesel (this jet must be heated for ignition temp -- butit takes time. + this badly injected jet is simply accumulated resulting lack of sparks etc).

I think the above is clear. Sorry if i explained it in not clear English.

Reporting Back.

Took it in to the garage who replaced the injectors.

Been fine ever since. it seems to run a bit smoother and now starts first time.

Before you lash out the cash... I had the same problem and came here last year for advice.

My Toyota Avensis 4D4 diesel was bad at starting with any temperature below 10 degrees C

Iv'e cured mine without spending 1 penny.

Put the key in and turn on but don't start it yet.

Pump the accelerator 4 times to the floor (it doesn't flood)

Then start with the accelerator to the floor.

It will catch 1st time - it did today at 4C
