I've got an Avensis 1.8 vvti 2004, last November I had my engine block/piston rings changed under Toyota Warranty to fix the problems with excessive oil consumption.
Within the last 10 months, twice I've had the following lights come up on the dashboard together:
- Engine Management light
- TRC Off
The first time it happened was back in April, I got it checked out at a local garage and it came up as P0325 Knock Sensor 1 Circuit Malfunction.
The second time it happened was at the beginning of September and this time I took it to Toyota to get it checked out as I thought it may be related to the work done on the engine previously. It turned out to be same error code.
Toyota advised that the Knock Sensor needs replacing at a cost of £250! When I questioned them about whether this was part of the engine work done to resolve the oil consumption issues they initially said it wasnt related at all. I then asked them as to where the Knock sensor is located and they said its on the engine block (which is what was changed wasnt it???), so they then admitted they would have had to remove it as part of the warranty work. But obviously they wont accept that the sensor may have been damaged in the process as it would be noticable straight away.
I've never had this problem with the sensot prior to any work taking place on the engine. I'm now stuck with what could be a damaged sensor and Toyota not accepting responsibility for it. On top of that, checking my dipstick the other day, its now down to half way after 6000 miles since the engine work was done, so whatever they did it hasnt resolved my oil consumption problems!
I'm contemplating writing a letter of complaint to Toyota GB Head Office as not only is my original problem not resolved, its caused 'Knock' on effects (no pun intended!) as well.
Any help/advice appreciated. Has anyone has had similar issues?
