Dealership Dilema - Ecu


Mick's ECU
 Share

Recommended Posts

:help: All help appreciated.

Basically rounding a corner on Sunday in my MKIII MR2, put my foot on the accelerator and nothing. Complete loss of power, dash lights up like a crimbo tree and I'm coasting to the side of the road.

No problem getting her to turn over, only problem is she only turns for about a second before she powers off again.

Two AA vans later I am being towed to my local dealership, with the knowledge that ignition, starter motor etc are all working correctly, but the car still will not turn over for more than a second.

Dealership have had the car for 4 days now, and have hooked it up to every computer known to man, but they (diagnostics) all say that the car is working fine, but we (me and the mechanics) can obviously see that this is nopt the case.

Dealership want to employ trial and error tactics and replace the ECU (seems sensible as the ECU should be spitting out error codes I guess). But I have to front the £900 for the ECU (I'm out of warranty). Which means that if the ECU is not the issue, I am left with a £900 bill and a car that still doesn't work.

Any ideas please?

Beg, steal or borrow one.

you don't even have to take the original out, just connect the multi-plugs and try. :thumbsup:

That's what I thought. I was all - "well that's get one off a used MKIII or borrow the one off the demonstrator, and see if it works with an different ECU".

The man from Toyota he say no! He say that once an ECU is programmed to a car it is permanantely programmed. It cannot be re-programmed and no 2 ECUs are the same.

Hence if they order one from Toyota and it's not the ECU that's the problem, I'll still be stung for the cost because the ECU is not resellabel and therefore cant be sent back to the manufacturer.

I think the whole thing smells dodge. problem is I dont know enough about car mechanics to prove them wrong. Plus my nose aint gonna get the car fixed.

- Mate of mine just rang to say sticky injectors could be the cause of powerloss????????????????????????????

Wouldn't have thought sticky injectors would suddenly shut the engine down.

I assume you tested for a dodgy ignition switch?

This is why I cannot STAND :censor: tard infested Toyota dealerships!!!

they are useless..infact they are worse then useless as they are money grabbing in their uselessness!!!

They clearly don't have a clue what they are talking about!!!

I have had similar experianced with them and ended up taking my car from the dealership, they tried to plant a £270 bill on me, for not actually doing anything.....

they are not mechanics, mechanics can diagnose problems, they are "fitters".

I would take your car out of the hands of these idiots and find a specialist auto electrition. :thumbsup:

How much is a Toyota Extended Waranty, pobably not as much as an ECU, if indeed you can get an extended warranty at this stage,

Just a thought

It is possible that an ECU is programmed to be car specific for immobiliser purposes. I have no idea if this applies to the mk3 mr2 though. If it is, then Toyota are almost certainly the only people who can sort a replacement for you.

There is no way they should be charging you for a replacement ECU if it turns out not to be at fault. IMO it doesn't sound like an ECU fault, and they are just clutching at straws because the diagnostic kit isn't telling them exactly what part to replace.

It sounds like it could well be a fuel pressure problem, and I would be surprised if the ECU was able to diagnose that. Check all your fuses, listen for the fuel pump and make sure it keeps running after the car is started. Check the fuel filter is not blocked.

I woud be inclined to try another dealer first of all, and maybe complain to Toyota UK. Even out of warranty, it could be argued that the ECU should not have failed.

If it does end up that you have a faulty ECU, you would be better off replacing it with an AEM aftermarket one. They cost about £1k plus installation + mapping, but would give you about 20 hp or more (based on people's results of chipping).

Thanks for the tips boys.

Giddle I'm not sure if its ignition as the car does physically turn over. Personally I think its a fuel / faulty immobaliser issue. But that's more gut than fact.

Know what your saying karma. Definately think its worth a second opinion from someone less likely to charge me 200% over reasonable prices.

Dave I'm hearing you. Tell you what I would have gone that route in hindsight, but I guess like nmost insurance they'll tell me where to get off as its a fault which has showed up prior to me taking out the policy.

Mick I would be surprised, You can buy a warranty at any Toyota branch I do believe, or even over the phone,

when I had a problem that Toyota could not sort they never even logged the fault in their computer system, if they have taken no money off you yet, then the computer probably wont know there is a problem. Maybe worth a shot and a visit to another Toyota garage?

top draw mikeb I'll give that a go.

What I meant with the ignition fault was that you can still turn an engine over on the "start" position but if there is a fault in the "run" position the engine will peter out once you let go. :thumbsup:
