Engine Cuts Out Without Warning - Garages So Far All At Sea...

[StephenBK]

The car is a 2.2 Diesel D-4D (estate) 05, bought from a dealer last October at just under 100K, fine until recently at 6K miles later. (I had reason to contact the previous owner who said all he knew was it had had a new injector).

In case useful here is the first incident; in the cold weather it was getting hard to start, 5 goes once, I put this down to the cold and an assumed old Battery - a service was nigh. Then one day, pulling away from the kerb it just stopped and refused to start. RAC got it going and we went to my garage, who said they'd do the service and see it anything turned up, which it didn't except that it had the wrong size Battery. The reason I suspect a connection with the following is it was only a couple of weeks before, and it didn't seem like a regular dead old Battery problem.

Anyhow, since then it started cutting out without the slightest warning. First 2 times at 60 on major roads, then leaving a roundabout, - these all about 200 miles apart, each time after a reasonable amount of time driving. Each time it starts again, unlike the very first time, but after an increasing amount of time in each case. 4th time, manoeuvring in a carpark. Good 2 minutes to start. Then, only about 10 miles later, and a good 5 minutes to start.

This last really freaked me out, so it was back to the garage (already booked in by that stage) but the fault lights on the dash were gone by the time it got there, and while they could read the old fault codes there was nothing actually wrong at the time. They kept it for a couple of days, gave it a serious drive about, it behaved impeccably. I got in to drive it away - and it wouldn't start!!! They took it to a local diesel specialist, who kept it several days and drove about at my expense but also found it behaved perfectly. The dreaded Intermittant Problem!

I've just got it back home again. The invoice lists;

"Carry out diagnostic test on vehicle Fault P0200 logged. Tested wiring from Injectors to Injector control Unit, all OK, Checked Injector resistances and for shorting to ground, ok.

Checked injector control unit terminals, all OK.

Road tested for 65 miles and rechecked for faults, OK."

(and that came to £150!)

All suggestions or advice gratefully received!

Ignition switch.

You say it has the wrong Battery fitted.?did the garage rule out the possibility that it could be part of the problem.

Interesting, nobody's mentioned that. Any suggestions what the issue might be, and the remedy?

Apparently the Battery it came with from the dealer was too small. It had always been a touch unenthusiastic to start, which I put down to the cold and the supposed age of the battery; so, is the suggestion that the use of an inappropropriate Battery Battery for however long (minimum from October to February, nearly 5K miles) is causing the current problem?

when they fitted a new injector did they code & calibrate it?

All I know from the previous only is 'it had an new injector' - not even sure if it was under his ownership or before. Would such a procedure not be the normal thing? ... and if not, would it not have shown up in what has been investigated so far (by a diesel specialist garage)?

I may be wrong but I think that only a Toyota dealer can do it. You need to try to draw Devon Aygo's' attention - he works for a Toyota dealer.

been hearing of a few edu failures recently, sounds like that, an intermittent electrical fault relating to the injector circuit

So if a T dealer fitted the part they would have been sure to do it properly ... if somebody else was able to procure the part but was not able to do it properly, why were they allowed to obtain the part?!

The previous owner to 4 months to reply to my request the first time ...

P0200 is indeed injector circuit. Its worth adding that physically the engine is running as sweet as can be, cold, hot or whatever.

EU anti-trust/competition law - same reason that there is so much theft of keyless cars ... It has it's good points but these are some of the down sides.

A 3rd party technically could do it afaik if they subscribe to the full Toyota tech. system but the annual cost of that is so high that probably nobody but a Toyota dealer is likely too.

Do we know that the "new injector" is actually a brand new Toyota part & not a pattern or refurb. part?

Nope, merely the fact of the change. I doubt the previous owner would know the implicatins, and would suspect they wouldn't go to a main dealer, though have no idea when the change was made. NB, they took months to reply to my request for info.

Its been sitting parked since Tuesday but will have a good work out Friday and Saturday. Is it legal to drive with fingers crossed?
