There is a developing problem on our Spanish RAV. What I can best describe as a hiccup when pulling away at low revs, or driving slowly, like the engine is dying, but doesn't, but then it kicks in with a bit of a jolt. At normal speeds it seems to be OK, but maybe my imagination, the revs seem to be a little higher than normal. Could it be the clutch, or has anyone had a similar problem? 2003, 4.2 auto petrol with approx 150000 miles. Could be a garage job!!  |

Is it a 4.2.5 i.e. does it have round front fogs and indicators in the headlights? If so then I can't comment but if it's an earlier RAV then it may be the start of the dreaded autobox ECU problem. If so it will only get worse and if so, it's imperative that you don't drive the car otherwise the box will self-destruct very quickly. It can be easily fixed by ECUtesting in Derby.

I know nothing specific about it, but when autoboxes start to play up, my first suggestion is replace the oil & ensure you have the correct level, it may or may not clear the problem, but it rules out an issue & is always a good idea anyway.

So what is the dreaded ECU problem, and are my symptoms typical of this? We are in Spain so Derby isn't an option, but our local mechanic is very good, and this may give him a starting point. |

We had that on our 4.2 auto the gearbox issue. Itwoild be awkward changing gear, rough gear changes, struggling to change gears. Every garage we spoke to said it was the gearbox, Toyota including, quoted over £3K. With advice from guys on here sent the gearbox ECU off for testing and it turns out it was the ECU cost around £180 or thereabouts. |

I will try and get the car into the garage next week, and at least have something to start from. Thanks for the suggestions. |

With advice from guys on here sent the gearbox ECU off for testing and it turns out it was the ECU cost around £180 or thereabouts. Ash has summarised the symptoms well. If it is the gearbox ECU ( and it affects early RAVs with squarish front fogs incorporating the indicators) then changing g/box oil or filters will have no effect. It is a well-known issue with the early RAV and is concerned solely with the ECU. It usually starts quite quickly with little warning and the symptoms are severe from the outset. When ours did it, it was on a drive home from Crewe and the car just seemed unable to make up its mind which gear it was supposed to be in. Accelerating made the symptoms worse and a trailing throttle eased them off. Just because you are in Spain doesn't preclude use of ECUtesting as they usually operate via post: you remove your ECU - it is behind the glovebox and is held in by Torx security bolts, so you will need a suitable set of bits - and send it off to them by secure post with their details form from their website ( www.ecutesting.com/?gclid=CjwKCAjwpKveBRAwEiwAo4PqmzsqGHROITUyE1n2ptVUveHC7TNth6cDI-8KNDoxduBfwJk9eudfKBoCMM4QAvD_BwE). Their website will give you a better idea of the symptoms. If they can fix it, they will email you to say so; if not they will only charge a nominal fee. Otherwise it costs about £200 - £300 I seem to recall. Hopefully though,it won't be this. Good luck.

Ours is a 2003, separate headlights, and indicators and driving lights in the lower front bumper. Would that make a difference/

You seem to say though that the indicators are in the lower front bumper in unit with the fogs and NOT in the trailing edge of the headlight unit. That being the case, yours is an early RAV and may have the g/box ECU issue. If you look at ECUtesting's website as advised in a previous post, they give all the symptoms (and stored EM codes) relating to this problem.

Only the early 4.2 suffered the ECU problem this was down to the gearbox being giving the incorrect information by the computer this was down to corrosion or burnt out chips/resistors, if you catch the problem early with a reconditioned ECU it should be as good as new again, my only reservation is you car is up on miles already so,if you got this problem fix could there be another issue around the corner ? Best way maybe to look at it is a few hundred pound spend may fix the gearbox but not worth a full gearbox rebuilt ....well unless the price of 4x4 in Spain dictates its worth spending 👍🏻👍🏻

As yet no. I am going to leave it with the garage that we use, over Christmas, while we are back in UK. The problem is intermittent, and generally seems to reoccur when under heavy load or during a long run. It's not too bad at the moment! |
