05 Blobeye WRX

Hi,

A week or so ago on driving away from home I noticed my speedometer (& odo) wasn't working. As far as I am aware it was last drive beforehand. Soon after the engine management light came on.

I thought it was the speed sensor on the gearbox, so after checking and cleaning all the connections around there, have just this evening fitted a new speed sensor. The old one was completely seized in and a nightmare to remove, requiring a couple evenings of chipping and chiselling/molegripping away, I had to destroy it.

Anyway, test drove it and speedo still doesn't work

Most people seem to mention this fault puts the car in 'limp mode', is this correct? I test drove it in anger tonight and it was revving over 6k rpm without any rev limiting in place. Anyone got any ideas?

Thanks

 

Thanks for the response. Ordered a ecu reader dongle.

I pulled the clocks out this evening and checked all the connections, all looks as it should, removed and replugged in, no luck as yet. Oddly noticed the fuse for the 'display' had been replaced at some point with a 20a fuse, I replaced that with the correct 10a while I was there.

Seems it might be the gear inside the transmission, is there any way to confirm this?

 

Thought I'd give an update on what happened with this.

Eventually I took it to Surrey Subaru Specialists, they had it for the morning and after much fault finding diagnosed it was indeed the gear inside the gearbox not turning anywhere near fast enough.

I asked for a quote to fix it but they messed me around on this for two weeks, "part has to come especially from Japan, Subaru aren't sure on part".

Eventually as my MOT was fast approaching I took it direct to Hardy Engineering in Leatherhead who booked it in straightaway and had the gearbox split and reassembled within a week. Great guys. They got the 'special Japanese part' next day from a Subaru dealer.

It was a £10 plastic cog that had stripped, apparently looked like it had just worn away.
